如何配置Spring和Apache Tiles定义以从classpath解析jsps

要配置Spring和Apache Tiles定义以从classpath解析jsps，请按照以下步骤操作：

首先，确保已将Spring和Apache Tiles相关依赖添加到项目中。在Maven项目中，可以将以下依赖添加到pom.xml文件中：

   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-web</artifactId>
</dependency><dependency>
   <groupId>org.apache.tiles</groupId>
   <artifactId>tiles-jsp</artifactId>
</dependency>

在Spring配置类中，配置Apache Tiles视图解析器。以下是一个示例配置：

import org.apache.tiles.definition.dao.ClassPathDefinitionsFactory;
import org.apache.tiles.definition.dao.DefinitionsDAO;
import org.apache.tiles.factory.AbstractTilesContainerFactory;
import org.apache.tiles.factory.BasicTilesContainerFactory;
import org.apache.tiles.impl.BasicTilesContainer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.view.UrlBasedViewResolver;
import org.springframework.web.servlet.view.tiles3.TilesConfigurer;
import org.springframework.web.servlet.view.tiles3.TilesView;
import org.springframework.web.servlet.view.tiles3.TilesViewResolver;

@Configuration
public class TilesConfig {

    @Bean
    public TilesConfigurer tilesConfigurer() {
        TilesConfigurer tilesConfigurer = new TilesConfigurer();
        tilesConfigurer.setDefinitions(new String[] { "classpath:/tiles-definitions.xml" });
        tilesConfigurer.setCheckRefresh(true);
        return tilesConfigurer;
    }

    @Bean
    public UrlBasedViewResolver tilesViewResolver() {
        TilesViewResolver tilesViewResolver = new TilesViewResolver();
        tilesViewResolver.setViewClass(TilesView.class);
        return tilesViewResolver;
    }

    @Bean
    public BasicTilesContainerFactory tilesContainerFactory() {
        BasicTilesContainerFactory factory = new BasicTilesContainerFactory();
        factory.setDefinitionsFactoryClass(ClassPathDefinitionsFactory.class);
        return factory;
    }

    @Bean
    public BasicTilesContainer tilesContainer(DefinitionsDAO definitionsDao) {
        BasicTilesContainer container = new BasicTilesContainer();
        container.setDefinitionsFactory(definitionsDao);
        return container;
    }
}

在项目的classpath下创建一个名为tiles-definitions.xml的文件，并添加以下内容：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE tiles-definitions PUBLIC "-//Apache Software Foundation//DTD Tiles Configuration 3.0//EN" "http://tiles.apache.org/dtds/tiles-config_3_0.dtd">
<tiles-definitions>
   <definition name="base.definition" template="/WEB-INF/views/layout.jsp">
        <put-attribute name="header" value="/WEB-INF/views/header.jsp" />
        <put-attribute name="body" value="" />
        <put-attribute name="footer" value="/WEB-INF/views/footer.jsp" />
    </definition>

   <definition name="home" extends="base.definition">
        <put-attribute name="body" value="/WEB-INF/views/home.jsp" />
    </definition>
</tiles-definitions>

在layout.jsp文件中，添加以下内容以包含头部、主体和尾部：

<!DOCTYPE html>
<html>
<head>
   <title>My Application</title>
</head>
<body>
    <jsp:include page="${header}" />
    <jsp:include page="${body}" />
    <jsp:include page="${footer}" />
</body>
</html>

现在，Spring应用程序将从classpath解析jsps，并使用Apache Tiles定义来组织页面布局。
