Replace one of annotation parameters with IntelliJ IDEA's Structural replace

问题

I have many classes with the Spring @ContextConfiguration annotation. The annotation has the classes parameter, which can be an array.

Now most of my classes look like this:

@RunWith(SpringJUnit4ClassRunner.class)         
@ContextConfiguration(classes = {
        ThisShellBeTwoClassesInContextHierarchyConfig.class,
        SomeTest.SomeTestConfig.class,
        WhateverConfig.class
})
@Transactional
public class SomeTest { ...

Desired output of some magical batch operation would be following:

@RunWith(SpringJUnit4ClassRunner.class)         
@ContextHierarchy(classes = {
        @ContextConfiguration(classes = { ConfigA.class }),
        @ContextConfiguration(classes = { ConfigB.class }),
        @ContextConfiguration(classes = {
            SomeTest.SomeTestConfig.class,
            WhateverConfig.class
        })
})
@Transactional
public class SomeTest { ...

So far, I was not even able to have the IntelliJ IDEA Structural replace tool find annotations with the classes parameter, let alone replacing it. Even simplified structure like this

@$Annotation$($param$ = { $ctx$ })

doesn't find anything. The occurrences of ctx are set to unlimited.

How should I properly work with the annotation parameters?

回答1:

It seems that because of a bug it is not possible to match arrays (ElementValueArrayInitializer) in annotation name-value pairs. You can match the annotation you want using a query like:

@$Annotation$($param$ = $value$)

But this is probably not very helpful.
