IllegalArgumentException in CustomizableTraceInterceptor

Just want to point out a problem with the org.springframework.aop.interceptor.CustomizableTr aceInterceptor

We used it the following way:

Code:

---

<bean id="loggingInterceptor"
 class="org.springframework.aop.interceptor.CustomizableTraceInterceptor">
        <property name="enterMessage">
            <value>$&#91;targetClassShortName&#93;.$&#91;methodName&#93;&#40;$&#91;arguments&#93;&#41; Types&#40;$&#91;argumentTypes&#93;&#41;</value>
        </property>
</bean>

---

To log the values, passed into our business facade.
The problem comes in with the the $[arguments] Placeholder. Passing a String containing a dollar sign $ throws a nice

Code:

---

java.lang.IllegalArgumentException: Illegal group reference
at java.util.regex.Matcher.appendReplacement(Matcher.java:554)
        at org.springframework.aop.interceptor.CustomizableTraceInterceptor.replacePlaceholders(CustomizableTraceInterceptor.java:321)
        at org.springframework.aop.interceptor.CustomizableTraceInterceptor.invokeUnderTrace(CustomizableTraceInterceptor.java:274)
        at org.springframework.aop.interceptor.AbstractTraceInterceptor.invoke(AbstractTraceInterceptor.java:77)
        at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:144)

---

So we throwed the arguments out of the logging.
Does anyone know about another solution? Are we doing something wrong here?
Besides this error this aop style of logging simply rocks. So easy and yet so powerful. Besides this little flaw.

Karsten,

Can you raise a JIRA issue for this and ask for it to be assigned to me. I'll put the fix in for 1.2.3.

Rob

Created a JIRA issue at SPR-1151. Issue is marked as resolved and the fix has been added to CVS.

Rob,
thx a lot for this quick fix. Sorry for not putting it in Jira so fast.
I am amazed by the speed of your response. Thank you.
Cheers,
Karsten.

Just downloaded the brand new 1.2.3 version. So I can confirm fix in Spring 1.2.3.
Thx again.

I tried to follow the above example. And I tried to get exception error, I could not see degug or log message anywhere. How Can I make to get these message?

I put the following def in ApplicationContext.xml

<bean id="traceInterceptor" class="org.springframework.aop.interceptor.Customi zableTraceInterceptor">
<property name="enterMessage">
<value>$[targetClassShortName].$[methodName]($[arguments]) Types($[argumentTypes])</value>
</property>
<property name="exitMessage"><value>EXIT - {1}{2}</value></property>
<property name="exceptionMessage"><value>EXIT - {1}{2}</value></property>
</bean>

<bean id="wbxml-builder" class="org.springframework.aop.framework.ProxyFact oryBean">
<property name="proxyInterfaces"><value>xxx.r.builder.Builde r</value></property>
<property name="interceptorNames">
<list>
<value>traceInterceptor</value>

Please help me to get this log?

Thanks,

Kai

Same problem with $[exception] placeholder remains in CustomizableTraceInterceptor. Strangely no one has been reported about it as sign '$' is quite frequently found in stack traces(e.g. in inner classes' names)
