我正在尝试使用一组类别记录实现过滤方法，作为模块升级的一部分。为此，我添加了
IS_ENABLED NUMBER(1,0)
到CATEGORY表，每行的0或1分别为false或true。
ID NAME DISPLAY IS_ENABLED
ORDER
12 Direct Mail 6 1
1 Annual reports null 0
2 Books 1 1
3 Brochures 2 1
4 Calendars null 0
5 Catalogs 3 1
6 Digital Print 5 1
7 Magazines
(sheetfed) 8 1
8 Magazines (web) 9 1
9 Printer's own
promotions 10 1
10 General print 7 1
我还通过添加
修改了Hibernate配置文件<property name="enabled" type = "boolean">
<column name="IS_ENABLED" />
</property>
并在POJO模型中添加带有getter和setter的相应布尔字段。该模型包含toString()方法，其中包括行记录的名称，顺序和启用状态。
public class Category implements java.io.Serializable {
private long id;
private String name;
private Short displayOrder;
private boolean enabled;
//getters and setters
@Override
public String toString(){
return this.id + "\t" + this.name + "\t" + this.enabled + "\t" + this.displayOrder + "\n";
}
我的问题是toString（）正在打印
Current category: 2 Books false 1
Current category: 3 Brochures false 2
Current category: 5 Catalogs false 3
Current category: 6 Digital Print false 5
Current category: 12 Direct Mail false 6
Current category: 10 General print false 7
Current category: 7 Magazines
(sheetfed) false 8
Current category: 8 Magazines
(web) false 9
Current category: 9 Printer's own
promotions false 10
Current category: 1 Annual
reports false null
Current category: 4 Calendars false null
正如你所看到的，一切都是虚假的，而不是它应该是什么。要使实例enabled属性反映数据库值，需要做些什么？
