Question

我用Spring 3 MVC编写了“Hello World”网站，现在我正在尝试使用Apache Tiles技术重写它。我正在使用Maven来构建我的项目。的pom.xml

的web.xml

tiles.xml

    <tiles-definitions>

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

HomeController.java

package com.michat.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HomeController {

    @RequestMapping("/")
    public String showHomePage() {
        return "home";
    }
}

我在WEB-INF的views目录中定义了footer.jsp，home.jsp，header.jsp和layout.jsp。为什么我会收到此错误？

请添加到您的dispatcher.servlet.xml

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:beans="http://www.springframework.org/schema/beans"
    xsi:schemaLocation="
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
        http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-3.2.xsd">

<context:annotation-config />
<mvc:annotation-driven />
<context:component-scan base-package="com.michat" />

<bean class="org.springframework.web.servlet.view.UrlBasedViewResolver">
    <property name="viewClass" value="org.springframework.web.servlet.view.tiles3.TilesView" />
</bean>

<bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles3.TilesConfigurer">
    <property name="definitions">
        <value>/WEB-INF/tiles-defs.xml</value>
    </property>
</bean>

这个

<context:annotation-config/>

将激活各种注释，例如@Required和@Autowired

这个

<mvc:annotation-driven />

需要具有注释驱动的控制器。

下面的配置只是扫描类路径以获取带注释的组件。

<context:component-scan base-package="com.antenna.nn.patient" />

UrlBasedViewResolver是viewResolver，允许将符号视图名称直接解析为URL。瓷砖需要这个。
