时间格式控制前面显示

/**
     * 创建时间
     */
    @Column(name = "CREATETIME")
    @DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss")
    private Date createtime;

<result column="CREATETIME" property="createtime" jdbcType="TIMESTAMP" />


MySQL中的类型也要如此，控制数据库数据是此类型
以上ajax即可
放在model中不是ajax return用这种
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>

<fmt:formatDate value='${roledetl.createtime}' pattern='yyyy-MM-dd HH:mm:ss' />




二：不在model中是ajax返回的，直接用不要<fmt:formatDate 标签

mysql时间完整显示
table中
`SENDER_TIME` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '发送时间',

map中
<result column="SENDER_TIME" property="senderTime" jdbcType="TIMESTAMP" />

实体中
@DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss")//这种可以不要
  private Date senderTime;
 
 
  查询条件对时间传入处理
     @RequestMapping(value = "/queryPageMessage")
    @ResponseBody
    public PageInfo<Message> queryPageMessage(@RequestParam(value = "pageNo", required = false) int pageNo,
                                                        @RequestParam(value = "pageSize", required = false) int pageSize,
                                                        @DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss") Date statTime,
                                                        @DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss") Date endTime,
                                                         Message message
                                                        ) {
