Spring boot：如何从构建 .war 文件中排除静态文件？ [复制]

Question

我正在将 Spring Boot 用于 Web 应用程序，远程服务器要求我将 .war 文件上传到其根目录并在每次进行更改时部署它。我已设法更改 applications.properties 选项 spring.resources.static-locations 以使用战争文件之外的资源，它对我来说正常工作。

但是，当我使用 Maven 构建应用程序时，它仍然在生成的 .war 文件中包含静态文件。 .war 文件的大小已经超过 50 MB，当我开始添加静态图像文件时，这可能会成为一个严重的问题。我该怎么做才能从“maven 包”生成的 .war 文件中排除所有静态文件？

下面是我的 Spring Boot 应用程序的 pom.xml 文件。静态文件也位于“${project.basedir}/src/main/resources/static”目录中。

你可以尝试在你的构建块中添加下面的块吗？

<resources>
            <resource>
                <directory>${project.basedir}/src/main/resources</directory>
                <filtering>true</filtering>
                <excludes>
                    <exclude>${project.basedir}/src/main/resources/static/*</exclude>
                </excludes>
            </resource>
            <resource>
                <directory>${project.basedir}/src/main/resources</directory>
                <filtering>false</filtering>
            </resource>
</resources>

编辑

<resources>
            <resource>
                <directory>${project.basedir}/src/main/resources</directory>
                <filtering>true</filtering>
                <excludes>
                    <exclude>**/static/*</exclude>
                </excludes>
            </resource>
</resources>
