spring boot mvc docker白标错误

我有一个运行在docker容器上的spring boot mvc应用程序。容器运行得非常好，但当我尝试在浏览器上访问应用程序时，我会看到一个白色标签错误页面，显示它找不到/WEB-INF/views/***.jsp。下面是我的pom.xml

当我在本地执行“java-jar target/LoginModel-0.0.1-SNAPSHOT.jar”并尝试在浏览器上查看它时，它工作得非常好，没有任何错误。我只有在尝试在docker容器上运行应用程序时才出现错误。错误到底在哪里

看起来您使用的是JSP，但您的应用程序是打包为JAR的。您应该将应用程序打包为WAR。文件还提到：

创建custom error.jsp页面不会覆盖错误处理的默认视图，应该使用自定义错误页面

在docker容器中运行简单的springboot web应用程序时，我遇到了类似的情况。我已经打包了我的应用程序和.jar，所以JSP页面的内容没有显示在浏览器上。我将打包更改为.war，然后再次运行该过程，并在浏览器中显示内容。

您需要将项目设置为war和Dockerfile，如下所示

FROM tomcat:8.5-alpine
VOLUME /tmp
ARG WAR_FILE
ADD ${WAR_FILE} /usr/local/tomcat/webapps/app.war
RUN sh -c 'touch /usr/local/tomcat/webapps/app.war'
ENTRYPOINT [ "sh", "-c", "java -Djava.security.egd=file:/dev/./urandom -jar /usr/local/tomcat/webapps/app.war" ]

<plugin>
    <groupId>com.spotify</groupId>
    <artifactId>dockerfile-maven-plugin</artifactId>
    <version>1.3.6</version>
    <configuration>
        <repository>${docker.image.prefix}/${project.artifactId}</repository>
        <buildArgs>
            <WAR_FILE>target/${project.build.finalName}.war</WAR_FILE>
        </buildArgs>
    </configuration>
</plugin>

还有像这样的pom插件

FROM tomcat:8.5-alpine
VOLUME /tmp
ARG WAR_FILE
ADD ${WAR_FILE} /usr/local/tomcat/webapps/app.war
RUN sh -c 'touch /usr/local/tomcat/webapps/app.war'
ENTRYPOINT [ "sh", "-c", "java -Djava.security.egd=file:/dev/./urandom -jar /usr/local/tomcat/webapps/app.war" ]

<plugin>
    <groupId>com.spotify</groupId>
    <artifactId>dockerfile-maven-plugin</artifactId>
    <version>1.3.6</version>
    <configuration>
        <repository>${docker.image.prefix}/${project.artifactId}</repository>
        <buildArgs>
            <WAR_FILE>target/${project.build.finalName}.war</WAR_FILE>
        </buildArgs>
    </configuration>
</plugin>
