使用IDEA 建立一个很基础的Spring项目时，之前用xml方式，写bean标签一直正常使用，改用注解方式后发现报错，显示：
Exception in thread "XXX" org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [XXX.class]; nested exception is org.springframework.core.NestedIOException: ASM ClassReader failed to parse class file - probably due to a new Java class file version that isn't supported yet: file [XXX.class]; nested exception is java.lang.IllegalArgumentException: Unsupported class file major version 57

最终发现，是Spring依赖与JDK版本不兼容导致。Spring创建时为低版本JDK，而最近运行此项目时使用的是现在安装的JDK22。于是将原先使用的 5.2.10.RELEASE 改为 6.1.0 报错解决。
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>6.1.10</version>
</dependency>
对于Spring 依赖的版本选择，可查阅https://mvnrepository.com/artifact/org.springframework/spring-context/6.1.10
