我不知道该怎么办。谢谢你回答我。我对英语很抱歉，我来自巴西。

Answer 1

似乎您混合了不同版本的spring-boot库和Spring：

• 对spring-boot-starter、spring-boot-autocigure和spring-boot-maven-plugin使用相同的1.5.6.release版本
• 我不使用Spring boot，但我假设它带有自己的Spring版本，所以尝试完全删除对org.springFramework：spring-context的依赖。
• 运行MVN dependency:tree以确保Spring和Spring Boot库的所有版本都是一致的
