Spring aspectj - compilation of external can weaving time

Question

I have a project that uses compilation time aspects. this project depends on another project that is included as a bank. I want to weave a class in a jar file at compile time. How can i achieve this.

thanks

Answer 1

This jar should be added to the inpath of the compiled project. The result will be a new set of class files. These new class files are woven and should be used at run time instead of the original jar.

How to set the input path depends on how you compile your code:

• In Eclipse / AJDT, you can set the path on the AspectJ Build project properties page. Here you can also set a folder in the path to specify a special location for these class files.
• From ant, with the iajc task, you can use the inpath attribute. See here for more information: http://www.eclipse.org/aspectj/doc/released/devguide/antTasks-iajc.html
• When using the ajc command, use the -inpath option. See here http://www.eclipse.org/aspectj/doc/released/devguide/ajc-ref.html .

The hard part is not to forget to use the original cans in the running application, but rather woven cans.

Answer 2

If you are using maven, you can also use the aspectj-maven plugin. It works well with eclipse (m2e).

In the plugin, simply specify the groupId / artifactId of the dependent jar, as well as in the / weaveDependencies / weaveDepedency configuration.
