SpringSecurity高级应用

1. SpringSecurity核心源码分析

分析SpringSecurity的核心原理,那么我们从哪开始分析?以及我们要分析哪些内容?

  1. 系统启动的时候SpringSecurity做了哪些事情?
  2. 第一次请求执行的流程是什么?
  3. SpringSecurity中的认证流程是怎么样的?

1.1 系统启动

当我们的Web服务启动的时候,SpringSecurity做了哪些事情?当系统启动的时候,肯定会加载我们配置的web.xml文件

web.xml中配置的信息:

  1. Spring的初始化(会加载解析SpringSecurity的配置文件)
  2. SpringMVC的前端控制器初始化
  3. 加载DelegatingFilterProxy过滤器

Spring的初始化操作和SpringSecurity有关系的操作是,会加载介绍SpringSecurity的配置文件,将相关的数据添加到Spring容器中

SpringMVC的初始化和SpringSecurity其实是没有多大关系的

DelegatingFilterProxy过滤器:拦截所有的请求。而且这个过滤器本身是和SpringSecurity没有关系的!!!在之前介绍Shiro的时候,和Spring整合的时候我们也是使用的这个过滤器。 其实就是完成从IoC容器中获取DelegatingFilterProxy这个过滤器配置的 FileterName 的对象。

系统启动的时候会执行DelegatingFilterProxy的init方法

代码语言:javascript
复制
protected void initFilterBean() throws ServletException {
    synchronized(this.delegateMonitor) {
        // 如果委托对象为null 进入
        if (this.delegate == null) {
            // 如果targetBeanName==null
            if (this.targetBeanName == null) {
                // targetBeanName = 'springSecurityFilterChain'
                this.targetBeanName = this.getFilterName();
            }
            // 获取Spring的容器对象
            WebApplicationContext wac = this.findWebApplicationContext();
            if (wac != null) {
                // 初始化代理对象
                this.delegate = this.initDelegate(wac);
            }
        }
​
    }
}

            // 如果targetBeanName==null
            if (this.targetBeanName == null) {
                // targetBeanName = 'springSecurityFilterChain'
                this.targetBeanName = this.getFilterName();
            }
            // 获取Spring的容器对象
            WebApplicationContext wac = this.findWebApplicationContext();
            if (wac != null) {
                // 初始化代理对象
                this.delegate = this.initDelegate(wac);
            }
        }
​
    }
}
代码语言:javascript
复制
protected Filter initDelegate(WebApplicationContext wac) throws ServletException {
    // springSecurityFilterChain
    String targetBeanName = this.getTargetBeanName();
    Assert.state(targetBeanName != null, "No target bean name set");
    // 从IoC容器中获取 springSecurityFilterChain的类型为Filter的对象
    Filter delegate = (Filter)wac.getBean(targetBeanName, Filter.class);
    if (this.isTargetFilterLifecycle()) {
        delegate.init(this.getFilterConfig());
    }
​
    return delegate;
}

init方法的作用是:从IoC容器中获取 FilterChainProxy的实例对象,并赋值给 DelegatingFilterProxy的delegate属性

1.2 第一次请求

客户发送请求会经过很多歌Web Filter拦截。

然后经过系统启动的分析,我们知道有一个我们定义的过滤器会拦截客户端的所有的请求。DelegatingFilterProxy

当用户请求进来的时候会被doFilter方法拦截

代码语言:javascript
复制
public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain) throws ServletException, IOException {
    Filter delegateToUse = this.delegate;
    if (delegateToUse == null) {
        // 如果 delegateToUse 为空 那么完成init中的初始化操作
        synchronized(this.delegateMonitor) {
            delegateToUse = this.delegate;
            if (delegateToUse == null) {
                WebApplicationContext wac = this.findWebApplicationContext();
                if (wac == null) {
                    throw new IllegalStateException("No WebApplicationContext found: no ContextLoaderListener or DispatcherServlet registered?");
                }
​
                delegateToUse = this.initDelegate(wac);
            }
​
            this.delegate = delegateToUse;
        }
    }
​
    this.invokeDelegate(delegateToUse, request, response, filterChain);
}

invokeDelegate

代码语言:javascript
复制
protected void invokeDelegate(Filter delegate, ServletRequest request, ServletResponse response, FilterChain filterChain) throws ServletException, IOException {
    // delegate.doFilter() FilterChainProxy
    delegate.doFilter(request, response, filterChain);
}

所以在此处我们发现DelegatingFilterProxy最终是调用的委托代理对象的doFilter方法

FilterChainProxy

过滤器链的代理对象:增强过滤器链(具体处理请求的过滤器还不是FilterChainProxy ) 根据客户端的请求匹配合适的过滤器链链来处理请求

代码语言:javascript
复制
public class FilterChainProxy extends GenericFilterBean {
    private static final Log logger = LogFactory.getLog(FilterChainProxy.class);
    private static final String FILTER_APPLIED = FilterChainProxy.class.getName().concat(".APPLIED");
    // 过滤器链的集合  保存的有很多个过滤器链  一个过滤器链中包含的有多个过滤器
    private List<SecurityFilterChain> filterChains;
    private FilterChainProxy.FilterChainValidator filterChainValidator;
    private HttpFirewall firewall;
// .....
}

代码语言:javascript
复制
// 处理用户请求
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
    boolean clearContext = request.getAttribute(FILTER_APPLIED) == null;
    if (clearContext) {
        try {
            request.setAttribute(FILTER_APPLIED, Boolean.TRUE);
            this.doFilterInternal(request, response, chain);
        } finally {
            SecurityContextHolder.clearContext();
            request.removeAttribute(FILTER_APPLIED);
        }
    } else {
        this.doFilterInternal(request, response, chain);
    }
​
}

doFilterInternal

代码语言:javascript
复制
private void doFilterInternal(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
    FirewalledRequest fwRequest = this.firewall.getFirewalledRequest((HttpServletRequest)request);
    HttpServletResponse fwResponse = this.firewall.getFirewalledResponse((HttpServletResponse)response);
    // 根据当前的请求获取对应的过滤器链
    List<Filter> filters = this.getFilters((HttpServletRequest)fwRequest);
    if (filters != null && filters.size() != 0) {
        FilterChainProxy.VirtualFilterChain vfc = new FilterChainProxy.VirtualFilterChain(fwRequest, chain, filters);
        vfc.doFilter(fwRequest, fwResponse);
    } else {
        if (logger.isDebugEnabled()) {
            logger.debug(UrlUtils.buildRequestUrl(fwRequest) + (filters == null ? " has no matching filters" : " has an empty filter list"));
        }
​
        fwRequest.reset();
        chain.doFilter(fwRequest, fwResponse);
    }
}

获取到了对应处理请求的过滤器链

SpringSecurity中处理请求的过滤器中具体处理请求的方法

代码语言:javascript
复制
public void doFilter(ServletRequest request, ServletResponse response) throws IOException, ServletException {
    if (this.currentPosition == this.size) {
        if (FilterChainProxy.logger.isDebugEnabled()) {
            FilterChainProxy.logger.debug(UrlUtils.buildRequestUrl(this.firewalledRequest) + " reached end of additional filter chain; proceeding with original chain");
        }
​
        this.firewalledRequest.reset();
        this.originalChain.doFilter(request, response);
    } else {
        ++this.currentPosition;
        Filter nextFilter = (Filter)this.additionalFilters.get(this.currentPosition - 1);
        if (FilterChainProxy.logger.isDebugEnabled()) {
            FilterChainProxy.logger.debug(UrlUtils.buildRequestUrl(this.firewalledRequest) + " at position " + this.currentPosition + " of " + this.size + " in additional filter chain; firing Filter: '" + nextFilter.getClass().getSimpleName() + "'");
        }
​
        nextFilter.doFilter(request, response, this);
    }
​
}

主要过滤器的介绍

https://www.processon.com/view/link/5f7b197ee0b34d0711f3e955

ExceptionTranslationFilter

ExceptionTranslationFilter是我们看的过滤器链中的倒数第二个,作用是捕获倒数第一个过滤器抛出来的异常信息。

FilterSecurityInterceptor

做权限相关的内容

代码语言:javascript
复制
    public void invoke(FilterInvocation fi) throws IOException, ServletException {
        if (fi.getRequest() != null && fi.getRequest().getAttribute("__spring_security_filterSecurityInterceptor_filterApplied") != null && this.observeOncePerRequest) {
            fi.getChain().doFilter(fi.getRequest(), fi.getResponse());
        } else {
            if (fi.getRequest() != null && this.observeOncePerRequest) {
                fi.getRequest().setAttribute("__spring_security_filterSecurityInterceptor_filterApplied", Boolean.TRUE);
            }
            // 抛出异常 ExceptionTranslationFilter就会捕获异常
            InterceptorStatusToken token = super.beforeInvocation(fi);
​
            try {
                fi.getChain().doFilter(fi.getRequest(), fi.getResponse());
            } finally {
                super.finallyInvocation(token);
            }
​
            super.afterInvocation(token, (Object)null);
        }
​
    }

ExceptionTranslationFilter 处理异常的代码

当用第二次提交 http://localhost:8082/login时 我们要关注的是 DefaultLoginPageGeneratingFilter 这个过滤器

代码语言:javascript
复制
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
    HttpServletRequest request = (HttpServletRequest)req;
    HttpServletResponse response = (HttpServletResponse)res;
    boolean loginError = this.isErrorPage(request);
    boolean logoutSuccess = this.isLogoutSuccess(request);
    if (!this.isLoginUrlRequest(request) && !loginError && !logoutSuccess) {
        // 正常的业务请求就直接放过
        chain.doFilter(request, response);
    } else {
        // 需要跳转到登录页面的请求
        String loginPageHtml = this.generateLoginPageHtml(request, loginError, logoutSuccess);
        // 直接响应登录页面
        response.setContentType("text/html;charset=UTF-8");
        response.setContentLength(loginPageHtml.getBytes(StandardCharsets.UTF_8).length);
        response.getWriter().write(loginPageHtml);
    }
}

generateLoginPageHtml

代码语言:javascript
复制
private String generateLoginPageHtml(HttpServletRequest request, boolean loginError, boolean logoutSuccess) {
    String errorMsg = "Invalid credentials";
    if (loginError) {
        HttpSession session = request.getSession(false);
        if (session != null) {
            AuthenticationException ex = (AuthenticationException)session.getAttribute("SPRING_SECURITY_LAST_EXCEPTION");
            errorMsg = ex != null ? ex.getMessage() : "Invalid credentials";
        }
    }
​

    sb.append("<!DOCTYPE html>\n<html lang=\"en\">\n  <head>\n    <meta charset=\"utf-8\">\n    <meta name=\"viewport\" content=\"width=device-width, initial-scale=1, shrink-to-fit=no\">\n    <meta name=\"description\" content=\"\">\n    <meta name=\"author\" content=\"\">\n    <title>Please sign in</title>\n    <link href=\"https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/css/bootstrap.min.css\" rel=\"stylesheet\" integrity=\"sha384-/Y6pD6FV/Vv2HJnA6t+vslU6fwYXjCFtcEpHbNJ0lyAFsXTsjBbfaDjzALeQsN6M\" crossorigin=\"anonymous\">\n    <link href=\"https://getbootstrap.com/docs/4.0/examples/signin/signin.css\" rel=\"stylesheet\" crossorigin=\"anonymous\"/>\n  </head>\n  <body>\n     <div class=\"container\">\n");

第一次请求的完整的流程

页面调试也可以验证我的推论

1.3 认证流程

UsernamePasswordAuthenticationFilter:专门处理用户认证请求的

在父类中AbstractAuthenticationProcessingFilter看doFilter的逻辑

代码语言:javascript
复制
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        HttpServletRequest request = (HttpServletRequest)req;
        HttpServletResponse response = (HttpServletResponse)res;
        if (!this.requiresAuthentication(request, response)) {
            // 如果不是必须要认证的请求就直接放过
            chain.doFilter(request, response);
        } else {
            if (this.logger.isDebugEnabled()) {
                this.logger.debug("Request is to process authentication");
            }
​
            Authentication authResult;
            try {
                // 获取认证的信息  客户端提交的表单信息
                authResult = this.attemptAuthentication(request, response);
                if (authResult == null) {
                    return;
                }
​
                this.sessionStrategy.onAuthentication(authResult, request, response);
            } catch (InternalAuthenticationServiceException var8) {
                this.logger.error("An internal error occurred while trying to authenticate the user.", var8);
                this.unsuccessfulAuthentication(request, response, var8);
                return;
            } catch (AuthenticationException var9) {
                this.unsuccessfulAuthentication(request, response, var9);
                return;
            }
​
            if (this.continueChainBeforeSuccessfulAuthentication) {
                chain.doFilter(request, response);
            }
​
            this.successfulAuthentication(request, response, chain, authResult);
        }
    }
​

attemptAuthentication在UsernamePasswordAuthenticationFilter实现

代码语言:javascript
复制
    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {
        if (this.postOnly && !request.getMethod().equals("POST")) {
            throw new AuthenticationServiceException("Authentication method not supported: " + request.getMethod());
        } else {
            // 获取表单提交的账号密码
            String username = this.obtainUsername(request);
            String password = this.obtainPassword(request);
            if (username == null) {
                username = "";
            }
​
            if (password == null) {
                password = "";
            }
            // 空处理
            username = username.trim();
            // 账号密码封装为对应的对象
            UsernamePasswordAuthenticationToken authRequest = new UsernamePasswordAuthenticationToken(username, password);
            this.setDetails(request, authRequest);
            // 认证操作
            return this.getAuthenticationManager().authenticate(authRequest);
        }
    }

authenticate

变量获取每个认证提供者,然后处理认证

具体处理认证的实现

此处就会进入到我们自定义的UserServiceImpl中

到这儿就和我们讲的数据库认证连接起来了

2.SpringBoot整合

2.1 整合实现

我们如何在SpringBoot项目里面使用SpringSecurity呢?

添加相关的依赖

代码语言:javascript
复制
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

启动访问

账号是:user 密码:控制台中有帮我们自动生成

2.2 自定义登录页面

我们通过Thymeleaf来实现,先创建一个登录页面

代码语言:javascript
复制
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <h1>登录管理</h1>
    <form th:action="@{/login}" method="post">
        账号:<input type="text" name="username"><br>
        密码:<input type="password" name="password"><br>
        <input type="submit" value="登录">
    </form>
</body>
</html>

添加对应的控制器

代码语言:javascript
复制
@Controller
public class LoginController {
​
    @RequestMapping("/login.html")
    public String goLoginPage(){
        return "/login";
    }
}

添加SpringSecurity的配置类

代码语言:javascript
复制
package com.bobo.config;
​
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
​
@Configuration
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {
​
    /**
     * 先通过内存中的账号密码来处理
     * @param auth
     * @throws Exception
     */

效果

2.3 数据库认证

关键配置

2.4 授权

3. SpringBoot中的源码分析

前面我们介绍了Spring中整合SpringSecurity的核心源码流程,那么中SpringBoot应该怎么看呢?

代码语言:javascript
复制
org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration, // 初始化
org.springframework.boot.autoconfigure.security.servlet.UserDetailsServiceAutoConfiguration,// 认证 创建默认的账号密码
org.springframework.boot.autoconfigure.security.servlet.SecurityFilterAutoConfiguration // 和过滤器链有关

默认账号密码

DelegatingFilterProxy

代码语言:javascript
复制
//
// Source code recreated from a .class file by IntelliJ IDEA
// (powered by FernFlower decompiler)
//
​
package org.springframework.boot.autoconfigure.security.servlet;
​
import java.util.EnumSet;
import java.util.stream.Collectors;
import javax.servlet.DispatcherType;
import org.springframework.boot.autoconfigure.AutoConfigureAfter;
import org.springframework.boot.autoconfigure.condition.ConditionalOnBean;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.boot.autoconfigure.condition.ConditionalOnWebApplication;
import org.springframework.boot.autoconfigure.condition.ConditionalOnWebApplication.Type;
import org.springframework.boot.autoconfigure.security.SecurityProperties;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.boot.web.servlet.DelegatingFilterProxyRegistrationBean;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.web.context.AbstractSecurityWebApplicationInitializer;
​
@Configuration(
    proxyBeanMethods = false
)
@ConditionalOnWebApplication(
    type = Type.SERVLET
)
@EnableConfigurationProperties({SecurityProperties.class})
@ConditionalOnClass({AbstractSecurityWebApplicationInitializer.class, SessionCreationPolicy.class})
@AutoConfigureAfter({SecurityAutoConfiguration.class})
public class SecurityFilterAutoConfiguration {
    private static final String DEFAULT_FILTER_NAME = "springSecurityFilterChain";
​
    public SecurityFilterAutoConfiguration() {
    }
​
    @Bean
    @ConditionalOnBean(
        name = {"springSecurityFilterChain"}
    )
    public DelegatingFilterProxyRegistrationBean securityFilterChainRegistration(SecurityProperties securityProperties) {
        // 获取DelegatingFilterProxy对象,并且设置 url-parttern=/*
        DelegatingFilterProxyRegistrationBean registration = new DelegatingFilterProxyRegistrationBean("springSecurityFilterChain", new ServletRegistrationBean[0]);
        registration.setOrder(securityProperties.getFilter().getOrder());
        registration.setDispatcherTypes(this.getDispatcherTypes(securityProperties));
        return registration;
    }
​
    private EnumSet<DispatcherType> getDispatcherTypes(SecurityProperties securityProperties) {
        return securityProperties.getFilter().getDispatcherTypes() == null ? null : (EnumSet)securityProperties.getFilter().getDispatcherTypes().stream().map((type) -> {
            return DispatcherType.valueOf(type.name());
        }).collect(Collectors.toCollection(() -> {
            return EnumSet.noneOf(DispatcherType.class);
        }));
    }
}
​

那么后面的处理又是一样的了,进入FilterChainProxy中
