项目的目录结构如图
-
UserAction，首先在action层把需要返给前端的数据组装好，源代码如下
package com.shengfeng.action; import java.util.HashMap; import java.util.Map; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; import com.shengfeng.po.User; import com.shengfeng.service.UserService; @Controller @RequestMapping("/user") public class UserAction { @Autowired @Qualifier("userService") private UserService userService; @RequestMapping("/userInfo.html") public ModelAndView getUserInfo() { User user = userService.getUserByUserId(1); Map<String,Object> userInfoMap = new HashMap<String,Object>(); userInfoMap.put("username",user.getUsername()); userInfoMap.put("password",user.getPassword()); userInfoMap.put("level",user.getLevel()); userInfoMap.put("sex",user.getSex()); userInfoMap.put("mobilephone",user.getMobilephone()); userInfoMap.put("img",user.getImg()); ModelAndView view = new ModelAndView("/user/userInfo"); view.addObject("userInfo",userInfoMap); return view; } }
3.然后spring的配置文件，applicationContext.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:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd"> <context:annotation-config /> <context:component-scan base-package="com.shengfeng"/> <bean id="velocityConfigurer" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer"> <property name="resourceLoaderPath"> <value>WEB-INF/view</value> </property> <property name="velocityProperties"> <props> <prop key="input.encoding">UTF-8</prop> <prop key="output.encoding">UTF-8</prop> </props> </property> </bean> <bean id="viewResolver" class="org.springframework.web.servlet.view.velocity.VelocityViewResolver"> <property name="contentType" value="text/html;charset=UTF-8" /> <property name="exposeSpringMacroHelpers" value="true" /> <property name="suffix" value=".vm" /> <property name="toolboxConfigLocation" value="WEB-INF/velocity-toolbox.xml" /> <property name="cache" value="false" /> </bean> </beans>
4.velocity-toolbox.xml

{ "username":"$!{userInfo.username}", "password":"$!{userInfo.password}", "level":"$!{userInfo.level}", "sex":$!{userInfo.sex}, "mobilephone":"$!{userInfo.mobilephone}", "img":"$!{userInfo.img}" } 6.web.xml

8.启动tomcat，访问http://localhost:8080/myweb/user/userInfo.html可以看到：
返回了一个json数据，大功告成
