Dear all,
I am developing an application using Tuscany 2.0 using java components
in which I would like to use AOP for cross-cutting concerns like
register exceptions and timing and logging some method calls, among
other things. However, I don't have a clear idea about how I can do it.
I have read a guide article
(http://tuscany.apache.org/logging-tracing-and-timing-in-tuscany.html)
which describes a module that use AspectJ in Tuscany.
I would like to create my own aspects and define their point cuts in the
aop.xml file. My question is, how Tuscany is aware of the existence of
the aop.xml in order to create the advices? Are the aspects loaded when
the Tuscany Runtime start up (like Spring) or do I need to specified it
from the command line?
My aop.xml is very simple, one aspect for logging and another for
exception management
<aspectj>
<aspects>
<aspect name="com.mystore.aspects.LoggingAspect" />
<concrete-aspect
name="org.apache.tuscany.sca.aspectj.ExceptionManagementAspect">
<pointcut name="methodCall"
expression="call(* com.mystore.services..*(..))"/>
</concrete-aspect>
</aspects>
<weaver options="-verbose">
<include within="org.apache.tuscany.sca..*" />
</weaver>
</aspectj>
Ant the structure of my project is:
MyStore
-->src/main/java/com/mystore/aspects
-->ExceptionManagementAspect.java
-->LoggingAspect.java
-->src/main/java/com/mystore/services
-->AccountantImpl.java
-->AccountService.java
-->CatalogService.java
-->StoreImpl.java
-->src/main/resources
-->META-INF
-->aop.xml
-->MyStore.composite
-->Lib
...
M2_REPO\org\aspectj\aspectjrt\1.6.8\aspectjrt-1.6.8.jar
M2_REPO\org\aspectj\aspectjweaver\1.6.8\aspectjweaver-1.6.8.jar
...
If it's not possible to loaded them when the app start up, can I get the
same goal using other things like applying policies?
Thanks,
Fran
