SpringMVC集成velocity模版

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"?>

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
