Question

调用仪表板主页时出现以下错误。http://localhost:8082/web/fix/dashboard

我从中了解到，JSP文件/WEB-INF/jsp/dashboard.jsp某种程度上丢失了，或者也许spring无法找到它，或者我做错了事。

为确保我尝试反编译jar，但缺少JSP文件。不知道在哪里？

我已将JSP文件放置在src/main/webapp/WEB-INF/jsp/dashboard.jsp中。

但是，仅在使用jar文件运行应用程序时才会出现此问题。在日食中工作正常。

java -jar application.jar

这是一个maven项目。

Application.properties

spring.profiles.active=dev
spring.main.allow-bean-definition-overriding=true
server.address=127.0.0.1
server.port=8082
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

请对此提供帮助

由于缺少jsp文件，并且正如您在反编译jar文件之后提到的那样，没有jsp文件意味着在打包jar文件时，maven不会复制它们。

尝试告诉Maven手动将webapp文件夹复制为类似于在摘要下方

<build>
    <resources>
      ...
      <resource>
        <directory>src/main/webapp</directory>
      </resource>
      ...
    </resources>
    ...
</build>
