无法使用 Struts 约定插件加载 bean
Unable to load bean using Struts convention plugin
我想使用基于注释的配置而不是基于 xml 的配置。 Struts有convention plugin做这种事。
所以我删除了 main/resources 中的 struts.xml 文件，添加了这个插件作为依赖项，在操作上添加了一些注释并尝试 运行 我的项目在服务器上（Tomcat 7).
当服务器启动时，我得到下一个堆栈跟踪：

问题是 struts 有 xwork-core 作为依赖项，所以它位于类路径中，但不知何故 tomcat 找不到它。这些是我来自 pom.xml 的依赖项：

我做错了什么？
如果您查看 maven 依赖项，struts2-core 已经对 xwork-core 有依赖项，因此您应该在构建应用程序时下载它。不同版本的插件可能会使插件停止工作或在启动时中断。您应该使用以下工件
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-core</artifactId>
<version>2.3.24</version>
</dependency>
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-convention-plugin</artifactId>
<version>2.3.24</version>
</dependency>
pom.xml有2分错误
1. struts2-core 已经包含xwork-core
2. struts2-core 的版本应该大于 than/equal 到 structs2-convention-plugin
的版本
