Spring boot 1.4.2.RELEASE 启动时出错 java.lang.ClassNotFoundException: org.springframework.beans.factory.ObjectProvider

Juz*_*Ali 5 spring hibernate spring-bean spring-boot

我正在尝试将 spring-boot 从 1.3 升级到1.4.2.RELEASE. 运行mvn spring-boot:run会引发以下错误。

Answer 1

Raf*_* G. 3

答案是：Ali 在他的 pom.xml 中使用了一些依赖管理插件，并定义了 4.2.4.RELEASE 属性。这些插件之一使用此属性来确定应下载哪些版本的 JAR。

在他的场景中，他必须记住将“spring-boot-starter-parent”的版本升级到兼容版本。
