spring Bean已经注册- struts2-核心依赖错误

我试图将一个项目迁移到Maven并声明Struts 2依赖项，但我被这个错误卡住了。我已经仔细检查了pom.xml依赖项，确保struts2-core只声明一次，添加了排除项和所有项。我还尝试了有xwork-core依赖项和无xwork-core依赖项，同样的错误。我真的卡住了，不知道如何继续。

我的错误：

首先，你需要添加struts2-core工件并测试它是否工作，然后添加Spring和/或其他插件。请参阅如何Create Struts 2 Web Application Using Maven To Manage Artifacts and To Build The Application。
核心struts2应用程序的pom.xml只需要

<dependency>
    <groupId>org.apache.struts</groupId>
    <artifactId>struts2-core</artifactId>
    <version>X.X.X.X</version>
</dependency>

字符串
其中X.X.X.X是具体版本，即2.3.16.3或2.3.24.1，它将下载所有其他依赖项。与其他框架集成使用插件，不要弄乱重复的依赖项。清理，重建，重新部署。检查WEB-INF/lib，它不应该包含来自不同版本的重复库。在您的情况下，struts2-core-2.3.16.3.jar和struts2-core-2.3.16.jar都加载在classpath。这是错误，不应该有两个不同版本的相同库。
您还可以使用其他插件

<dependency>
    <groupId>org.apache.struts</groupId>
    <artifactId>struts2-json-plugin</artifactId>
    <version>2.3.16.3</version>
</dependency>

<dependency>
    <groupId>org.apache.struts</groupId>
    <artifactId>struts2-spring-plugin</artifactId>
    <version>2.3.16.3</version>
</dependency>

<dependency>
    <groupId>org.apache.struts</groupId>
    <artifactId>struts2-struts1-plugin</artifactId>
    <version>2.3.16.3</version>
</dependency>

型
可以添加到pom.xml。
