maven项目中搭建spring框架

1.首先看一下，项目结构：

 

2.在pom.xml添加依赖，这样spring所需要的jar包就自动下载到项目中了

<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/xsd/maven-4.0.0.xsd">

   <dependencies>
   <!-- 依赖servlet，导入servlet所需jar包  -->

    </dependency>
    <!-- 依赖spring，导入spring所需jar包  -->

    </plugins>
  </build>
</project>

 

3.web.xml配置

<?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"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    id="schedule-console" version="3.0">
  
  <!-- 配置spring的servlet -->  
  <servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>
org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>/WEB-INF/applicationContext.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>
  
    <!-- Spring的log4j监听器 -->  
    <listener>  
        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>  
    </listener>  
    
    <!-- 字符集 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>  
        <init-param>  
            <param-name>forceEncoding</param-name>  
            <param-value>true</param-value>  
        </init-param>  
    </filter>  
    <filter-mapping>  
        <filter-name>CharacterEncodingFilter</filter-name>  
        <url-pattern>/*</url-pattern>  
    </filter-mapping>
    
  <!-- 欢迎页 -->
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
  <!-- 设置session有效时间 -->
  <session-config>  
  <session-timeout>9999</session-timeout>  
</session-config>
    
    </web-app>

 

4.applicationContext.xml配置

<?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:util="http://www.springframework.org/schema/util"  
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:jpa="http://www.springframework.org/schema/data/jpa" xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
        http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.9.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

    
      <!-- viewresolver -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/">
        </property>
        <property name="suffix" value=".jsp">
        </property>
    </bean>
    
    <!-- 使用如下两个class激活@RequestMapping annotation -->
    <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>   
    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>

    <!-- 扫描service,controller -->
    <context:component-scan 
        base-package="com.zp.test"/>

    <!-- handlermapping @RequestMapping,
    @ResponseBody,@ExceptionHanlder -->
    <mvc:annotation-driven/>
    
</beans>

 

 

5.编写jsp页面

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<script type="text/javascript" src="js/jquery-1.10.1.min.js"></script>
<script>
function test(){
    
    $.ajax({
         url:"/test2/test.do",
         data:{},
         type:"post",
         dataType:"json",
         success:function(data){
             alert("success");
         },
         error:function(){
             alert("error");
         }
     });
    
    
}

</script>
<body>
<input type="button" value="test" onclick="test();"/>
</body>
</html>

 

6.编写Controller

package com.zp.test.controller;

import java.util.HashMap;
import java.util.Map;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;


@Controller
public class TestController {
    
      @RequestMapping("/test.do")
      @ResponseBody
      public Map<String,Object> test(){
          System.out.println("测试");
          String s = "ok";
          Map<String,Object> resMap=new HashMap<String,Object>();
          resMap.put("code", s);
          return resMap;
      }
      

}

 

7.右键工程——run as——run configuration...——goals:tomcat:run——点击run

启动服务，运行项目
