SpringMVC环境搭建

  前段时间刚刚接触springMVC，学习了下springMVC的环境搭配，为了让自己以后用到的时候能够更快的搭建起来，所以写下这篇博客使自己更好记忆。

1.先创建一个maven工程

   右键new一个project，选择maven project

这里可以选择保存路径

选择webapp1.0

项目的名字

2.将依赖添加到项目中

   在pom.xml中添加依赖

 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

  <packaging>war</packaging>
  <version>0.0.1-SNAPSHOT</version>
  <name>springmvc Maven Webapp</name>

  </properties>

</project>

3.在web.xml中配置spring配置文件的加载

<!DOCTYPE web-app PUBLIC

 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>


<!--解决中文乱码问题 -->
<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>


<!-- 让web项目自动加载spring配置文件 -->
<servlet>
   <servlet-name>springmvc</servlet-name>
   <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
   <init-param>
    <param-name>contextConfigLocation</param-name>
   
    <!-- 让web项目加载springmvc的配置文件 -->
<param-value>classpath:springmvc.xml</param-value>
</init-param> 
<load-on-startup>1</load-on-startup>
</servlet>
  
 <servlet-mapping>
  <servlet-name>springmvc</servlet-name>
  <url-pattern>*.do</url-pattern>
 </servlet-mapping>


</web-app>

4.写spring配置文件

将application.xml名字改成web.xml中的名字springmvc.xml,这个xml在resources文件夹下

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="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.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">
        
<!-- spring配置文件中添加组件扫描 
扫描这个包下的所有类-->
<context:component-scan base-package="com.ex.controller"></context:component-scan>


<!-- scpringmvc注解驱动 -->
<mvc:annotation-driven/>
<!-- 配置数据源 -->
<!-- <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"> -->
<!--  <property name="driverClassName" value="com.mysql.jdbc.Driver"></property> -->

<!--  连接字符串 --> 
<!-- <property name="url" value="jdbc:mysql://localhost:3306/access?characterEncoding=utf8" /> -->
<!-- <property name="username" value="root" /> -->
<!-- <property name="password" value="" /> -->
<!-- <property name="maxActive" value="20" /> -->
<!-- <property name="initialSize" value="5" /> -->
<!-- <property name="maxWait" value="60000" /> -->
<!-- <property name="minIdle" value="1" /> -->
<!-- </bean> -->




<!-- 定义jdbc连接对象 -->
<!-- <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate"> -->
<!-- <property name="dataSource" ref="dataSource" /> -->
<!-- </bean> -->


<!-- 上传文件 -->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
     <property name="defaultEncoding" value="utf-8" />
     
     <!-- 最大上传大小 104857600 字节 ~  100M -->
     <property name="maxUploadSize" value="104857600"/>
     
     <!-- 最大上传服务器的内存大小  -->
     <property name="maxInMemorySize" value="4096"/>
</bean>
</beans>

5.写控制器Controller

package com.ex.controller;


import java.util.Map;


import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;


import com.ex.model.User;
import com.ex.service.UserService;
//转换为对象，用什么注解.  @Controller @Compontent
//业务逻辑，注解
@Controller
@RequestMapping("/user/") 
public class UserController {

// UserService userService =new UserService();



// @RequestMapping("quer")
// public User querUser(@PathVariable(value="id") Integer id){
// System.out.println(id);
// return userService.QuerUserById(id);
// }
// spring mvc 配置接口的路径
@RequestMapping("/show1/{a:[a-z]+}{b:\\d+}")
//@RequestMapping("/show1/{a:[a-z]+}")
//@RequestMapping("/show1/{a}")
public String show1(@PathVariable(value="a") String a,
@PathVariable(value="b") Integer b
){
System.out.println("a:"+a);
System.out.println("b:"+b);
return "/index.jsp";
}


@RequestMapping(value="/cart")
@ResponseBody
public Map<String, Object> cart(HttpServletRequest request) {

HttpSession session = request.getSession();

String username = (String)session.getAttribute("username");

System.out.println("username:" + username);

return null;
}

@RequestMapping(value="/login")
@ResponseBody
public Map<String, Object> login(HttpServletRequest request) {

HttpSession session = request.getSession();

// 将用户的信息保存到 session 变量中
session.setAttribute("username", "zhangsan");


return null;
}
// @RequestMapping("findUserByReq")
// public String findUserByReq(
// @RequestParam(value="username",required=false) String username,
// @RequestParam(value="password") String password,
// HttpServletRequest request
// ){
// System.out.println("进到用户的控制层了！！！！");
// System.out.println("username:"+username+""+"password"+password);
// request.setAttribute("username", username);
// return "/fildUser.jsp";
//
// }
@RequestMapping("edit")
public String bianji(@RequestParam(value="id") int id,
@RequestParam(value="name") String name,
@RequestParam(value="adds") String adds
){
System.out.println("id:"+id);
return "";
}
// // {a} 说明是1个可变的变量
// @RequestMapping(value="/detail/{a}") // 根路径
// public  String detail(@PathVariable(value="a") Integer id){
// System.out.println("id:"+id);
// return "/index.jsp";
// }

}
