获取输入值到ejb 3.1抛出拦截器

Question

Do you know if there is any way to log, throw an interceptor, the input values of the called method?

my actual interceptor is

public class Interceptor {
@AroundInvoke
public Object interceptor(InvocationContext invocationcontext) throws Exception{
    //Stampa prima del metodo
    long startTime = System.currentTimeMillis();
    log.debug("Invoked method: "+invocationcontext.getMethod().getName());
    //here I would like to log also parameters. 
    try{
        return invocationcontext.proceed();
    } finally{
        log.debug("End of method: " + invocationcontext.getMethod().getName());
        log.debug(" duration: " + (System.currentTimeMillis() - startTime));
    }
}
}

The bean is

@Interceptors({Interceptor.class})

@Stateless public class MrBean implements MrBeanRemote, MrBeanLocal {

/**
 * Default constructor. 
 */
public MrBean() {       
}

public void print(String in){
    System.out.println("Print: " + in);
}
}

So if i call the print method with in = "print that" the interceptor should log "print that". Is it possible? Thanks in advance

您要记录方法的参数，因此可以在InvocationContext上使用getParameters（）方法： http : //docs.oracle.com/javaee/6/api/javax/interceptor/InvocationContext.html#getParameters（）
