springmvc创建的基础

1、springmvc的web.xml配置

2、在web-inf下创建classes文件夹

3、创建spring-mvc.xml

<?xmlversion="1.0"encoding="UTF-8"?>

<beansxmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:aop="http://www.springframework.org/schema/aop"

xmlns:tx="http://www.springframework.org/schema/tx"xmlns:context="http://www.springframework.org/schema/context"

   xmlns:mvc="http://www.springframework.org/schema/mvc"

xsi:schemaLocation="

      <!-- 组件扫描 -->

     <context:component-scan base-package="com.lanou.mvctest"></context:component-scan>

     <!-- 动态 全局资源试图解析器 -->

   <bean    class="org.springframework.web.servlet.view.InternalResourceViewResolver">

     <property name="prefix"value="/jsp/"></property>

     <property name="suffix" value=".jsp"></property>

   </bean>

     <!--注解驱动 -->

     <mvc:annotation-driven></mvc:annotation-driven>

     <!-- ************************* -->

     <!-- 静态通过资源处理 ，不会分给动态-->

     <mvc:resourceslocation="/static/"  mapping="/static/**"/>

</beans>

5、配置文件基本完毕

6、在webContent下创建jsp动态文件夹

static下方js 、css、.html文件

7、以下应用实例

package com.lanou.mvctest.controller;

import java.util.HashMap;

import java.util.Map;

import javax.annotation.Resource;

import org.apache.log4j.Logger;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import org.springframework.ui.Model;

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

import org.springframework.web.bind.annotation.RequestParam;

import org.springframework.web.bind.annotation.ResponseBody;

import org.springframework.web.servlet.ModelAndView;

import com.lanou.mvctest.entiry.User;

import com.lanou.mvctest.services.IUserService;

/**

 * struts的属性分装

 * springMVC基于参数封装

 *

 */

//视图解析器相当于struts2的result

@Controller

@RequestMapping("/user") //映射文件 namespace

public classUserController {

publicstatic  Loggerlog=Logger.getLogger(UserController.class);

//@Autowired //根据类型自动装配

@Resource(name="userService")//根据名字装配

publicIUserService userService;

@RequestMapping("/login")//接口

@ResponseBody//返回json 时配置

//返回值String类型  返回动态页面 //参数可以直接对象 

    publicMap<String,Object>login(@RequestParam(name="name")String username,Stringpwd){

log.info("请求到这里了");

System.out.println(username);

  Map<String,Object>  result=newHashMap<>();

  result.put("status",1);

  result.put("data","hahahahaha");

    return result;

    }

//参数可以是原生的servlet的内置对象

@RequestMapping("/test")

public String test(Modelmodel){

model.addAttribute("username","fuxionglongferqhjniogerqjmngioreqj'jpjn'");

return"user/bbb";

}

@RequestMapping("/test1")

publicModelAndView  test1(){

Map<String,Object>  map=newHashMap<>();

map.put("username","zhangkaikai");

ModelAndView modelAndView  =newModelAndView("user/bbb",map);

returnmodelAndView;

}

@RequestMapping("/service")

@ResponseBody

publicString testService(Useruser){

  userService.login(user);

return"success";

}

}
