我使用Spring-AOP來建議一個Spring管理bean,它擴展了實現3個接口的抽象類。在繼承層次結構中還有其他由spring管理的bean。Spring-AOP和SLF4J

我試圖採取最少侵入性的方法,使用彈簧LTW:

<context:component-scan base-package="com.foo.aop"/> 
<!-- ... --> 
<aop:aspectj-autoproxy proxy-target-class="true"/> 
<context:load-time-weaver/> 

使用廚房水槽的方法,試圖讓登錄的情況發生:

@Aspect 
@Component 
public class ForStackOverflow { 

    private final Log commons = LogFactory.getLog(ForStackOverflow.class); 
    private final org.apache.log4j.Logger log4j = org.apache.log4j.Logger.getLogger(ForStackOverflow.class); 
    private final Logger jul = Logger.getLogger(ForStackOverflow.class.getSimpleName()); 
    private final org.slf4j.Logger slf4j = org.slf4j.LoggerFactory.getLogger(ForStackOverflow.class); 

    @Pointcut(value="within(com.foo.aop.AbstractClass+) " + 
        "&& execution(* advisedMethod(com.foo.SomeType)) " + 
        "&& args(someType)") 
    private void adviseMe(SomeType someType){} 

    @After(value="adviseMe(com.foo.SomeType) && args(someType)", argNames = "someType") 
    public void itWorked(SomeType someType) { 
     String msg = "DEBUG DEBUG DEBUG DEBUG DEBUG DEBUG DEBUG DEBUG DEBUG DEBUG DEBUG DEBUG"; 
     logIt(msg);    
     IsNotNull(someType, "someType"); 
     String message = "SomeType [ " + someType + "] loaded."; 
     status(message); 
     logIt(msg); 
    } 

    void status(String message) {   
     logIt(message); 
    } 

    private void logIt(String msg){ 
     System.out.println("STDOUT: " + msg); 
     System.err.println("STDERR: " + msg); 
     commons.warn("COMMONS: " + msg); 
     log4j.warn("LOG4J: " + msg); 
     jul.warning("JUL: " + msg); 
     slf4j.warn("SLF4J: " + msg); 
    } 
} 

我有證據表明我的方法正在被建議,因爲我可以從那裏拋出並看到堆棧軌跡彈出到適當的位置。

但日誌記錄是難以捉摸的。

(我log4j的銜接和共享記錄到SLF4J。應用程序需要Java util的記錄作爲其底層的實現。)

哪裏是questio在你的問題中標記? – kan 2012-02-13 16:16:55
