将Spring Boot 1.4.4升级到1.5.4 - NoClassDefFoundError：ServletRegistrationBean

时间：2017-06-23 23:08:20

标签： java spring maven spring-mvc spring-boot

我正在使用Maven构建的Java服务并使用Spring Boot框架。截至目前，我服务的pom.xml有以下内容：

    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.4.5.RELEASE</version>

我尝试升级到Spring Boot 1.5.4，但我在应用程序启动时遇到错误（基本上，当我运行项目的.JAR文件时）。

我通过浏览找到的是，在两个Spring Boot版本之间不推荐使用org.springframework.boot.context.embedded.ServletRegistrationBean类;相反，使用org.springframework.boot.web.servlet.ServletRegistrationBean类。

但是，我仍然坚持使用ServletRegistrationBean类。我没有在我的服务的pom.xml或Java代码中的任何导入中看到任何直接引用。这使我相信它可能用于下游依赖，但有很多，很难知道它可能在哪里。

我已经尝试过mvn依赖：树来查看依赖树，但它在缩小范围方面似乎没什么帮助。还有什么想法吗？

1 个答案:

答案 0 :(得分：3)

我能够成功构建，但只有在修复了我的服务的pom.xml中引用的下游依赖项之后。

很难追查，因为它是依赖的依赖;最终，Maven依赖树确实帮助我至少弄清楚我可以缩小导入到项目中的依赖项的位置。

确切的问题是，所涉及的依赖项导入了org.springframework.boot.context.embedded.ServletRegistrationBean;正如我在问题中所说，这被弃用了org.springframework.boot.web.servlet.ServletRegistrationBean。

我只需要确保导入已更新并且我的项目中使用了新的依赖项，并且升级到Spring 1.5.4有效。
