解决方式: 对下一个操作,强制进行却换


@DataSource(name=DataSource.dataSourceMaster)
  SyncJob selectByJob(SyncJob syncJob);


数据源利用AOP注解 却换代码:


    public void before(Method method, Object[] args, Object target)   
            throws Throwable {   
    	//这里DataSource是自定义的注解,不是java里的DataSource接口 
        if (method.isAnnotationPresent(DataSource.class))    
        {   
            DataSource datasource = method.getAnnotation(DataSource.class); 
            if(null == datasource || (null != datasource && null == datasource.name())) 
            	DataSourceContextHolder.setDataSource(datasource.dataSourceMaster); 
    		else { 
    			System.out.println(datasource.name()); 
    			DataSourceContextHolder.setDataSource(datasource.name());   
    		} 
        }   
           
    }
