若我使用旧版本运行，一切都很好，但当升级到1.2.5时，我看到了上面的错误。如何修复此异常，非常感谢

尝试检查在上打开的相关问题

您似乎需要更新版本的Spring framework，如下所述：

Spring Boot 1.2需要Spring Framework 4.1.5或更高版本，而不是 与SpringFramework 4.0兼容

谢谢@aUserHimselt：我正在查看你们链接中关于Spring boot的版本。它有效吗？接受答案或发布此解决方案的输出，以便其他有类似问题的人可以使用。@hi aUserHimself:是的，它起作用了，我已将所有内容更新到最新版本1.5.2。在每个版本中，API都发生了更改，所以我必须更新代码，无论如何，非常感谢：）

@Configuration
@ComponentScan
@EnableAutoConfiguration
@Import({SearchContext.class, WebContext.class })

public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
