9.SpringMVC环境搭建（XML启动方式）
1.创建控制类
package com.shs.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class ShsController {
@RequestMapping("/getShs")
@ResponseBody
public String getShs(){
return "ok";
}
}
2.resouces目录下创建spring-mvc.xml
内容为：
package com.shs.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class ShsController {
@RequestMapping("/getShs")
@ResponseBody
public String getShs(){
return "ok";
}
}
3.web.xml更改为
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">
<display-name>Archetype Created Web Application </display-name>
<!-- 配置springmvc DispatcherServlet -->
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<!--java反射机制加载 -->
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!--servlet初始化，加载创建的xml -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mvc.xml</param-value>
</init-param>
<!-- 让springmvc DispatcherServlet优先加载-->
<load-on-startup>1</load-on-startup>
</servlet>
<!-- 客户端发送所有请求，都会先达到dispatcherServlet静态资源，控制器类中请求-->
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
4.设置tomacat,在tomacat的lib文件下引入下面的依赖包
5.测试
