篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了total commander 不能重命名以黑体显示的文件?相关的知识,希望对你有一定的参考价值。
有人遇到过吗?如何解决?
可能没表述清楚,我是想批量重命名,不是针对单个文件重命名,谢谢!
压缩文件或文件夹到当前目录下,可以用ATL+C、再按“=”键,将两边窗口设成同一路径,再ALT+F5压缩;还可以点击鼠标右键(时间稍长点),调出右键菜单,找到压缩解压软件,也可以在同一目录下操作。
Hibernate命名策略
hibernate的命名策略,可以减少对数据库标识符命名的维护,进一步减少这部份命名的重复性代码量,以提高维护。
hibernate的命名方式,有两类,一类是显式命名,一类是隐式命名。
- 显式命名:在映射配置时,设置的数据库表名,列名等,就是进行显式命名。
- 隐式命名:显式命名一般不是必要的,所以可以选择当不设置名称,这时就交由hibernate进行隐式命名,另外隐式命名还包括那些不能进行显式命名的数据库标识符。接口ImplicitNamingStrategy,就是用于实现隐式命名。
- 过滤命名:接口PhysicalNamingStrategy,用于对显式命名或隐式命名进一步过滤处理。
示例:
TestTable1Impl.java
@Entity // 隐式命名表名 @Table public class TestTable1Impl { //--------------------------------------------------------------- // Field //--------------------------------------------------------------- @Id @Column() @GeneratedValue(strategy = GenerationType.IDENTITY) private Long testId; @Column(length = 20) private String testName; @ManyToOne private TestTable2Impl testForeign; //--------------------------------------------------------------- // Method //--------------------------------------------------------------- public Long getId() { return testId; } public void setId(Long id) { this.testId = id; } public String getName(){ return testName; } public void setName(String name){ this.testName = name; } public TestTable2Impl getTestForeign() { return testForeign; } public void setTestForeign(TestTable2Impl testForeign) { this.testForeign = testForeign; } }
TestTable2Impl.java
@Entity // 显式命名表名 @Table(name = "TestTable2Impl") public class TestTable2Impl { //--------------------------------------------------------------- // Field //--------------------------------------------------------------- @Id @Column() @GeneratedValue(strategy = GenerationType.IDENTITY) private Long testId; @Column(length = 20) private String testName; //--------------------------------------------------------------- // Method //--------------------------------------------------------------- public Long getId() { return testId; } public void setId(Long id) { this.testId = id; } public String getName(){ return testName; } public void setName(String name){ this.testName = name; } }
