在Spring MVC中调用API并从update方法中选择正确的选项,可以按照以下步骤进行:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>5.3.10</version>
</dependency>
@Controller
注解标记该类,并使用@RequestMapping
注解指定请求的URL路径。@Controller
@RequestMapping("/api")
public class ApiController {
@RequestMapping("/update")
public String update() {
// 在这里编写处理update请求的逻辑
return "update_success";
}
}
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<context:component-scan base-package="com.example.controller" />
<mvc:annotation-driven />
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
/WEB-INF/views/
目录下创建一个名为update_success.jsp
的JSP文件,用于显示更新成功的信息。<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<!DOCTYPE html>
<html>
<head>
<title>Update Success</title>
</head>
<body>
<h1>Update Successful!</h1>
</body>
</html>
至此,你已经完成了在Spring MVC中调用API并从update方法中选择正确的选项的步骤。当访问/api/update
路径时,将会执行update
方法,并返回update_success.jsp
页面显示更新成功的信息。
