将项目SDK从jdk_16换成jdk_1.8即可

开发环境

  • 系统：Windows 10 x64
  • 项目SDK环境：jdk_16
  • 开发工具：IntelliJ IDEA 2021.1 x64
  • pom.xml如下
   <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>5.0.5.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>javax.annotation</groupId>
            <artifactId>jsr250-api</artifactId>
            <version>1.0</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>5.0.5.RELEASE</version>
        </dependency>

异常产生

项目结构

所有类均按照Spring注解配置正确，运行测试代码时抛错

    AnnotationConfigApplicationContext applicationContext = new AnnotationConfigApplicationContext();
    applicationContext.register(SpringConfiguration.class);
    applicationContext.refresh();
    UserService userService = applicationContext.getBean("userService", UserService.class);
    userService.save();

异常如下（部分）

Exception in thread "main" java.lang.IllegalStateException: Cannot load configuration class: com.timber.config.SpringConfiguration
	at org.springframework.context.annotation.ConfigurationClassPostProcessor.enhanceConfigurationClasses(ConfigurationClassPostProcessor.java:414)
	at org.springframework.context.annotation.ConfigurationClassPostProcessor.postProcessBeanFactory(ConfigurationClassPostProcessor.java:254)
	at org.springframework.context.support.PostProcessorRegistrationDelegate.invokeBeanFactoryPostProcessors(PostProcessorRegistrationDelegate.java:

异常解决

将项目SDK从jdk_16换成jdk_1.8

重启IDEA，重新加载项目，异常解决
