AspectJ 匹配 return 类型作为与泛型的接口
AspectJ matching return type as interface with generics
我正在尝试创建一个 AspectJ 方面来拦截具有通用接口的返回方法。
这是我的 AspectJ
@AspectJ
public class MyAspect {
@AfterReturning("execution(java.util.Collection+<mypackage.MyAbstractEntity+> mypackage.mvc.controllers..*.*(..))", returning = "list")
public doStuff(JoinPoint j, Collection<MyAbstractEntity> list) {
}
}
这是我的class,我想编织成:
package mypackage.mvc.controller;
public class MyController {
// MyEntity extends MyAbstractEntity
public List<MyEntity> findAll() {
}
}
我做错了什么?
已解决!
将"plus"放在泛型定义之后("plus"表示"classes that extends it"):
java.util.Collection<mypackage.MyAbstractEntity+>+
并将 "list" 收缩为 "?extends":
public doStuff(JoinPoint j, Collection<? extends MyAbstractEntity> list) {
代码将如下所示:
@AspectJ
public class MyAspect {
@AfterReturning("execution(java.util.Collection<mypackage.MyAbstractEntity+>+ mypackage.mvc.controllers..*.*(..))", returning = "list")
public doStuff(JoinPoint j, Collection<MyAbstractEntity> list) {
}
}
