java - 将方面添加到实现类而不是接口(interface)

Question

我们有一个实现多个接口(interface)的类。我们想为整个类添加一些切入点 - 而不是为它的特定接口(interface)。

如何使用 Spring AOP 来完成？是否可以将方面应用于非接口(interface)类？

Answer 1

是的，你必须使用 CGLIB 来代理类。参见 section 7.1.3 of the spring docs

Spring AOP can also use CGLIB proxies. This is necessary to proxy classes, rather than interfaces. CGLIB is used by default if a business object does not implement an interface. As it is good practice to program to interfaces rather than classes, business classes normally will implement one or more business interfaces.

神奇的是通过以下定义代理目标类...

<aop:config proxy-target-class="true">
    <!-- other beans defined here... -->
</aop:config>
