Java 将Spring Boot与现有Spring应用程序集成

java spring hibernate spring-mvc

Java 将Spring Boot与现有Spring应用程序集成,java,spring,hibernate,spring-mvc,Java,Spring,Hibernate,Spring Mvc,我不熟悉弹簧靴。我已经阅读了文档和一些教程。我从他们那里了解到，SpringBoot使开发变得容易。SpringBoot可以轻松创建独立的、生产级的、基于Spring的应用程序，您可以“直接运行”。在辅导课之前，一切都很好但是假设您已经有了一个应用程序（SpringMVC+Hibernate+MySql），我可以在这个应用程序中利用SpringBoot吗？为了找出答案，我决定将SpringBoot集成到一个项目中。我从下载了一个示例工作代码，并尝试集成Spring Boot。我不能让它工作。

但是假设您已经有了一个应用程序（SpringMVC+Hibernate+MySql），我可以在这个应用程序中利用SpringBoot吗？为了找出答案，我决定将SpringBoot集成到一个项目中。我从下载了一个示例工作代码，并尝试集成Spring Boot。我不能让它工作。我越来越不正常了

Exception in thread "main" java.lang.IllegalArgumentException: Cannot instantiate interface org.springframework.context.ApplicationListener : org.springframework.boot.logging.ClasspathLoggingApplicationListener

根据上述错误，应用程序无法找到从jar依赖项定义的类

GenericApplicationListener

是从spring版本

4.2

AFAIK中添加的

<org.springframework-version>4.0.3.RELEASE</org.springframework-version>

除此之外,

maven中的育儿是什么
如何更改子pom中的版本

将帮助您自定义应用程序。

Spring Boot为您管理依赖项。springboot版本中的所有依赖项都经过测试，可以与合理的默认值协同工作。可以定义您自己的或覆盖的，但建议您不要这样做。请参阅以下官方文件：

<org.springframework-version>4.0.3.RELEASE</org.springframework-version>
