Spring Boot-无法使用aspectj进行加载时间编织

Question

curl -i http://localhost:8080/test-app/motd

[AppClassLoader@58644d46] warning javax.* types are not being woven because the weaver option '-Xset:weaveJavaxPackages=true' has not been specified.

Answer 1

好吧，我快速浏览了一下你的GitHub项目。POM非常奇怪，例如，它不包含对Spring-Instrument的任何依赖。此外，您依赖于aspectjweaver 1.8.2，但依赖于aspectjrt 1.5.4。您确实应该对两者使用相同的版本。

无论如何，我在命令行上尝试了不同的Java代理，似乎仅仅使用AspectJ weaver（result：exception）或Spring Instrument（result：方面不起作用，正如您所描述的那样）是不够的。您需要同时使用：

java -javaagent:path/to/aspectjweaver-1.8.2.jar -javaagent:path/to/spring-instrument-4.1.0.RELEASE.jar ...

这适用于您的代码，当根据您的描述使用Curl时，在控制台上产生以下结果：

[AppClassLoader@58644d46] warning javax.* types are not being woven because the weaver option '-Xset:weaveJavaxPackages=true' has not been specified
