Spring 正在尝试在存在 aop 时子类化记录组件

Question

我有一个 spring 引导应用程序，我在其中使用了方面。最近，我尝试将我的 @ConfigurationProperties 类记录转换为 java 记录，但失败并显示 "Cannot subclass final class {..}Properties"。似乎 spring 正在尝试为我的记录制作 cglib 代理，这显然失败了。有什么办法可以告诉 spring 不要为特定的类创建代理吗？

编辑：

属性：

@ConfigurationProperties(prefix = "foo.bar")
public record MyProperties(String a,
                           String b) {

}

我克隆了您的 MCVE 存储库。谢谢，很有帮助。

请注意，Java 条记录隐式为最终记录。因此，Spring AOP 无法将它们子类化以创建动态代理。

你需要改变

@Pointcut("within(foo.bar..*) @target(org.springframework.stereotype.Service)")

（请同时注意语法错误，缺少&&）到

@Pointcut(
  "within(foo.bar..*) && " +
  "@target(org.springframework.stereotype.Service) && " +
  "!@within(org.springframework.boot.context.properties.ConfigurationProperties)"
)

我只是添加了几个换行符以使切入点更具可读性。
