关键代码

package com.xx.mvc.controller;

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import java.text.SimpleDateFormat;
import java.util.Date;

/**
 * @author xx
 * @version 1.0
 */
@Controller
public class JSONController {

    @RequestMapping(value = "/dateToJson", produces = "application/json;charset=utf-8")
    @ResponseBody
    public String dateToJson() throws JsonProcessingException {
        ObjectMapper mapper = new ObjectMapper();
        //关闭它的时间戳功能
        mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
        //时间格式化：自定义日期格式对象
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        //让mapper指定时间日期格式为simpleDateFormat
        mapper.setDateFormat(simpleDateFormat);
        //创建一个日期对象
        Date date = new Date();
        return mapper.writeValueAsString(date);
    }
}
