摘要: 对java程序员来说,最好用的模版引擎有velocity和freemarker。相比较 FreeMarker 而言,Velocity 更加简单、轻量级,但它的功能却没有 FreeMarker 那么强大。这里介绍一下velocity模版的集成~
  1. 项目的目录结构如图


  2. 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

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
