实体里用的java.util.date,数据库用的是datetime,页面是字符串。将页面标签的内容添加到数据库
public class BaseInformation {
//信息主键
private String id;
//信息标题
private String title;
//信息类型id(需要在数据字典定义)
private String typeCode;
//属性id(需要在数据字典定义)
private String propertityId;
//信息可视范围,部门可见或者整个单位可见,值是组织结构的id
private String scope;
//内容
private String content;
//发布人id
private String releaseId;
//是否发布,1发布,0保存
private Integer released;
//接收人id,对应tb_base_information_receiver的主键
private String receiver;
//创建时间就是发布时间
private Date createDate;
//更新时间
private Date updateDate;
//开始时间
private Date beginDate;
//结束时间
private Date endDate;
//定时器,规定什么时候发布信息
private Date timer;
。。。。。省略getter和setter

string和date的类型转换失败,此时在实体中,对需要进行转换的类型添加如下注解,实现java.lang.String和java.util.Date之间自动转换
@DateTimeFormat(pattern="yyyy-MM-dd")//页面写入数据库时格式化
@JSONField(format="yyyy-MM-dd")//数据库导出页面时json格式化
即
既然java.lang.String和java.util.Date之间可以自动转换了,后台就不需要通过request获取参数来进行转换,可以将红方格中的注释掉
1.注解@JsonFormat
2.注解@DateTimeFormat
@DateTimeFormat的使用和@jsonFormat差不多,首先需要引入是spring还有jodatime,spring我就不贴了
关于@DateTimeFormat和@JsonFormat还可以参考https://blog.csdn.net/eeeeasy/article/details/81201819
