无法访问我的 docker servlet 应用程序上的 Web 资源(无 spring)[重复]

问题描述 投票:0回答:1

在我的 java 11、基于 tomcat 和 maven 的 servlet 应用程序中,我无法访问客户端的 Web 资源。比如css文件、图片无法加载,xhtml文件也无法加载。

在服务器端,它们是可以访问的。

我尝试在 Maven 插件的配置中手动添加这些资源。

但是没有效果。

我的目录结构:
enter image description here

我的 Dockerfile:

FROM maven:3-eclipse-temurin-11 AS build

WORKDIR /deploy
COPY . .
RUN mvn package -DskipTests

FROM tomcat:8.5
COPY --from=build /deploy/target/amazonlite-1.0-SNAPSHOT.war /usr/local/tomcat/webapps/amazonlite.war
EXPOSE 8080
ENTRYPOINT ["catalina.sh", "run"]

资源在我的 docker 容器的 /usr/local/tomcat/webapps/project 目录中可用。

tomcat servlets

经过几个小时的工作,我找到了解决方案。

在我的 web.xml 中,我确实需要指定我希望通过我的网络服务器访问的资源(css/等)。

<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>/css/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>/jpg/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>/html/*</url-pattern>
</servlet-mapping>

在 webapp-dir 中,我确实需要应用这些目录结构,我在 web.xml 中指定为可访问资源。
