爲了使用Spring AOP實現Logging,我遵循了以下簡單的步驟。但它似乎不起作用。任何幫助將是非常有用切入點不能與Spring AOP一起使用
1)創建MyLoggingAspect創建一個類(TixServiceImpl)類
import org.aspectj.lang.ProceedingJoinPoint;
public class MyLoggingAspect
{
public MyLoggingAspect() {
super();
System.out.println("Instantiated MyLoggingAspect");
}
public Object log(ProceedingJoinPoint call) throws Throwable
{
System.out.println("from logging aspect: entering method [" + call.toShortString()
+"] with param:"+call.getArgs()[0]);
Object point = call.proceed();
System.out.println("from logging aspect: exiting method [" + call.toShortString()
+ "with return as:" +point);
return point;
}
}
2),我想記錄
public class TixServiceImpl implements TixService{
@Override
public void calculateSomething() {
String s = "did some calculation..";
System.out.println(s);
}
@Override
public String getTixName() {
return null;
}
}
3 )創建了spring-aspectj.xml文件
<beans...
<bean id="LoggingAspect" class = "MyLoggingAspect"/>
<aop:config>
<aop:aspect ref="LoggingAspect">
<aop:pointcut id="myCutLogging"
expression="execution(* TixService*.*(..))"/>
<aop:around pointcut-ref="myCutLogging" method="log"/>
</aop:aspect>
</aop:config>
</beans>
4)創建了一個簡單的測試客戶端(TixClient)
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
public class TixClient {
public static void main(String[] a){
ApplicationContext context = new FileSystemXmlApplicationContext("conf/spring-aspectj.xml");
TixService tix = new TixServiceImpl();
tix.calculateSomething();
String s = tix.getTixName();
System.out.println("End of the the client invocation!!");
}
}
5)它給了我下面的輸出
...
Instantiated MyLoggingAspect
did some calculation..
End of the the client invocation!!
感謝您的提示,它的工作。如果在線提供的示例/示例/教程中提到了這將是一件好事。 – 2009-01-19 03:38:25
