今天完成的事情：
1.完成步骤三
首先：引入依赖，先指定json-taglib所在仓库，进行下载
<repositories>
<repository>
<id>java.net</id>
<url>http://maven.jahia.org/maven2</url>
</repository>
</repositories>
<dependency>
<groupId>atg.taglib.json</groupId>
<artifactId>json-taglib</artifactId>
<version>0.4.1</version>
</dependency>
运行结果：
UserController
package com.wp.json.controller;
import com.github.pagehelper.PageHelper;
import com.wp.json.beans.User;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
@Controller
@RequestMapping("/user")
public class UserController {
@RequestMapping(value ="/insertview",method = RequestMethod.GET)
public ModelAndView addUserView(ModelAndView mv) {
mv.setViewName("insert");
return mv;
}
@RequestMapping(value = "/json",method= RequestMethod.POST)
public ModelAndView insertUser(@ModelAttribute User user, ModelAndView mv) throws Exception {
user.setName(user.getName());
user.setQq(user.getQq());
user.setBro(user.getBro());
mv.addObject("user",user);
mv.setViewName("json");
return mv;
}
@RequestMapping(value = "/json1",method= RequestMethod.GET)
public ModelAndView insertUser1(User user, ModelAndView mv) throws Exception {
user.setName("enen");
user.setQq(1233333);
user.setBro("广告歌");
mv.addObject("user",user);
mv.setViewName("json");
return mv;
}
}

明天计划的事情：
继续任务
遇到的问题：
1.刚开始运行时报400错误，可能原因是我用表格存放了其他多余的数据，因为其他数据的干扰导致数据类型的报错。
2.Jetty就是不好使
收获：
了解了Json的作用及简单的操作方式。
