在mybatis和spring整合后 , 在把springmvc整合进来

在maven里创建web工程

然后进行mybatis和spring的整合步骤(写在其他博客里)

在把springmvc 加进来

步骤  
引入依赖

配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    	xmlns="http://java.sun.com/xml/ns/javaee"

    	<display-name>SSM-01</display-name>
    	<welcome-file-list>
    		<welcome-file>index.html</welcome-file>
    		<welcome-file>index.htm</welcome-file>

    		<welcome-file>default.htm</welcome-file>

    	<context-param>
    		<param-name>contextConfigLocation</param-name>

    	<servlet>

    	</servlet>
    
    
    	<servlet-mapping>

    		<filter-name>characterEncoding</filter-name>
    		<url-pattern>/*</url-pattern>
    	</filter-mapping>
    
    </web-app>

添加springmvc的配置文件

springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    	xmlns:context="http://www.springframework.org/schema/context"
    	xmlns:mvc="http://www.springframework.org/schema/mvc"
    	xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.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-4.3.xsd">
     	
     	
     	
     	<context:component-scan base-package="com.liy.controller" use-default-filters="false">
     		<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
     	</context:component-scan>
     
     	
     	
     	<mvc:annotation-driven>
     		<mvc:message-converters register-defaults="true">
                <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                  <constructor-arg value="GBK" />
                </bean>
            </mvc:message-converters>
     	</mvc:annotation-driven>
     	
     
     	
     	
     	
     
      <bean  class="org.springframework.web.servlet.view.InternalResourceViewResolver">
     		<property name="prefix" value="/"></property>
     		<property name="suffix" value=".jsp"></property>
     	</bean>  
     </beans>

然后写个controller层

@Controller
    public class MyController {
    	
    	@Resource
    	private IUserService service;
    	
    	
    	@RequestMapping("/fun")
    	public String  fun(Map mm){
    		List<User> list = service.query();
    		
    		System.out.println(list);
    		mm.put("list", list);
     		return "hello";
    	}
    	
    	@RequestMapping("/delete")
    	@ResponseBody
    	public String delete(){
    		
    		int row = 0 ;
    		row = service.delete(19);
    		String msg = "";
    		if (row == 1) {
    			msg = "ok";
    		}else {
    			msg ="no";
    		}
    		System.out.println(msg);
    		return msg;
    	}
    	
    	
    	@RequestMapping("/insert")
    	@ResponseBody
    	public String insert(){
    		 
    		int row = 0 ;
    		row = service.insert(new User("a","aaa",17,"gaag"));
    		String msg = "";
    		if (row == 1) {
    			msg = "成功";
    		}else {
    			msg ="失败";
    		}
    		return msg;
    	}
    	
    	@RequestMapping("/update")
    	@ResponseBody
    	public String update(){
    		 
    		int row = 0 ;
    		row = service.update(new User(20,"aa","aaa",19,"gaag"));
    		String msg = "";
    		if (row == 1) {
    			msg = "ok";
    		}else {
    			msg ="no";
    		}
    		System.out.println(msg);
    		return msg;
    	}
