java.lang.ClassNotFoundException: org.aspectj.util.PartialOrder$PartialComparable
提问by Nikem
I am using Spring 4.2.4.RELEASE in my web application and I would like to remove the dependency on aspectjweaver.jar from it. I don't use AOP directly and I certainly don't use AspectJ. But my application fails with the following exception:
我在我的 web 应用程序中使用 Spring 4.2.4.RELEASE，我想从中删除对 aspectjweaver.jar 的依赖。我不直接使用 AOP，当然也不使用 AspectJ。但我的应用程序失败，出现以下异常：

Is the any way to completely remove the dependency on aspectjweaver.jar ?
有没有办法完全消除对 aspectjweaver.jar 的依赖？
回答by Adam C.
I encountered this problem when using the @Transactionalannotation on a class annotated with @Componentin Spring Boot similar to: https://spring.io/guides/gs/managing-transactions/
我在 Spring Boot 中使用@Transactional注解的类上使用注解时遇到了这个问题，@Component类似于：https: //spring.io/guides/gs/managing-transactions/
The easiest way to fix it is to add the proper Maven dependency:
修复它的最简单方法是添加适当的 Maven 依赖项：
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.8.9</version>
</dependency>

No, you cannot. You are using Spring AOP. The Spring project spring-aopdoes have a hard dependency on aspectjweaver.jar. Read the Spring-aop docsthat clearly identifies it as a dependency.
你不能。您正在使用 Spring AOP。Spring 项目spring-aop确实对aspectjweaver.jar. 阅读明确将其标识为依赖项的 Spring-aop文档。

The answer is no. Spring AOP is syntactically an AspectJ subset, thus it uses AspectJ classes for parsing pointcuts. It also exposes AspectJ classes like JoinPoint, ProceedingJoinPointand AspectJ annotations like @Poinctut, @Before, @After, @Around, @DeclareParentsetc.
答案是不。Spring AOP 在语法上是一个 AspectJ 子集，因此它使用 AspectJ 类来解析切入点。它还公开的AspectJ类，如JoinPoint，ProceedingJoinPoint和AspectJ注解喜欢@Poinctut，@Before，@After，@Around，@DeclareParents等。
回答by Raj kannan Iyyappan
Adding spring-boot-starter-aop dependency would resolve the issue, if you are facing it in the springboot application.
如果您在 springboot 应用程序中遇到它，添加 spring-boot-starter-aop 依赖项将解决该问题。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-aop</artifactId>
</dependency>
