Question

我有这个课程，我想知道是否有可能以statuc的方式获取课程名称

public abstract class AbstractDAProcedureMenuReceivedHandler<T extends AbstractDAProcedureMenuReceivedEvent> extends DaCommonEventHandler<T> {

    private static final Logger logger = LoggerFactory.getLogger ( this.getClass());

Answer 1

为什么不只是“硬编码”这个类名？对于记录器，这是常见的方法

public abstract class AbstractDAProcedureMenuReceivedHandler<T extends AbstractDAProcedureMenuReceivedEvent> extends DaCommonEventHandler<T> {
    private static final Logger logger = LoggerFactory.getLogger(AbstractDAProcedureMenuReceivedHandler.class);
    ...
}

其他所有解决方案都是为此坦白地说

Answer 2

private static final Logger LOGGER = LoggerFactory.getLogger(AbstractDAProcedureMenuReceivedHandler.class);

Answer 3

使用此：

--------------------------------------
| Id  | Operation             | Name | 
--------------------------------------
|   0 | SELECT STATEMENT      |      |    
|*  1 |  HASH JOIN RIGHT ANTI |      |     
|   2 |   INDEX FAST FULL SCAN| IDX  |  
|*  3 |   TABLE ACCESS FULL   | TAB  |  
--------------------------------------
Predicate Information (identified by operation id):
---------------------------------------------------

   1 - access("PRINCIPAL"="T"."PRINCIPAL")
       filter(ROWID<>"T".ROWID)
   3 - filter("T"."PRINCIPAL" IS NOT NULL)

在静态属性中从Abstract类获取类名称
