HIbernate與不支持boolean的數據庫之間的映射

    1.JPA本身是不支持boolean。可以用Hibernater自带的标签.修改如下.  

    @Column(name = "manager_log")
    @org.hibernate.annotations.Type(type="yes_no")
    private boolean manageLog = false; // 能否管理系统日志  

    2.当然你也可以不用Hibernater的标签,但要改写setter,getter方法  

    给你一个例子:
    @Entity
    public class User {
      @Id
      private Integer id;  

      @Basic
      private Character enabled;  

      public Boolean getEnabled() {
        if (enabled == null) return null;
        return enabled == 'Y' ? Boolean.TRUE : Boolean.FALSE;
      }  

      public void setEnabled(Boolean enabled) {
        if (enabled == null) {
          this.enabled = null;
        } else {
          this.enabled = enabled == true ? 'Y' : 'N';
        }
      }
    }
