mybatis中string和date的转换方式

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;
