SpringMVC集成velocity模版
-
項目的目錄結構如圖
-
UserAction，首先在action層把需要返給前端的數據組裝好，源代碼如下
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"?>
