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';  
        }  
      }  
    }
