找到了org.springframework.web.servlet.DispatcherServlet，但是缺少另一个必需的类

Question

EAR包已部署到WAS8.5.5.7。 用户界面可以显示。 但是，当UI尝试触发Java函数时，我得到以下响应。

Error 404: javax.servlet.UnavailableException: SRVE0203E: Servlet [rrbapp]: org.springframework.web.servlet.DispatcherServlet was found, but is missing another required class.

SRVE0206E: This error typically implies that the servlet was originally compiled with classes which cannot be located by the server.

SRVE0187E: Check your class path to ensure that all classes required by the servlet are present.SRVE0210I: This problem can be debugged by recompiling the servlet using only the classes in the application's runtime class path

SRVE0234I: Application class path=[/opt/WebSphere85/profiles/appprofile/installedApps/wascell/abcapp.ear/cn-abc-web-app-1.0.0.war/WEB-INF/classes:

Answer 1

它似乎是Jar依赖项错误，您是否尝试过运行mvn clean install ，它应该可以解决您的问题。 运行此命令，然后尝试重新部署

Answer 2

在我的软件包中添加“ slf4j-log4j12” jar之后，它可以正常工作而不会出现此错误。 我认为原因是，如果没有服务器中的这个jar，日志将无法打印，因此程序会在开始时停止。
