整合spring和springmvc
1、在web.xml中添加spring监听器
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
version="4.0">
<display-name>Archetype Created Web Application</display-name>
<!-- 配置spring监听器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 配置前端控制器 -->
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 加载springmvc的配置文件 -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<!-- 启动服务器 -->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- 配置中文乱码过滤器 -->
<filter>
<filter-name>characterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>characterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
2、测试spring和springmvc
- 在com.gychen.controller的TestDemo里写测试代码
package com.gychen.controller;
import com.gychen.service.ClassInfoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class TestController {
@Autowired
private ClassInfoService classInfoService;
@RequestMapping("/test")
public String testIndex(){
System.out.println("测试springmvc内容");
return "test";
}
@RequestMapping("/test01")
public String testSpring(){
classInfoService.queryClassInfoAll();
System.out.println("测试spring和springmvc整合");
return "test01";
}
}
- 在pages里新建test01.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Spring和SpringMVC整合测试</title>
</head>
<body>
Spring和SpringMVC整合测试
</body>
</html>
- 运行Tomcat并输入
http://localhost:8080/library/test01
出现页面结果，表明整合成功
