我正在使用 Maven 多模块，其中的战争取决于另一场战争。

Spring Boot webapp 依赖于一个只提供 html 文件的基本 webapp。

当我运行 Spring Boot 应用程序时，我可以从主 webapp（Spring Boot 应用程序）访问服务和 html，但我无法从依赖关系战争 (404) 访问 html 文件。但是这些 html 文件在 Spring Boot webapp 大战中被很好的打包了...

这是一个显示问题的项目：
https ://github.com/ctiebault/spring-boot-war-overlays

这个项目有 2 个战争模块：

  • dependency-webapp : 仅服务于 html (/dependency/index.html) 的基本 webapp
  • main-webapp ：Spring Boot webapp（从 Spring Guides gs-serving-web-content复制）。这个 webapp 依赖于dependency-webapp。

这是 main-webapp pom.xml：

<?xml version="1.0" encoding="UTF-8"?>

运行网络应用程序：

mvn install
cd main-webapp
mvn spring-boot:run

编辑 1：这是我尝试访问 html 页面时的日志：

知道出了什么问题吗？

Spring Boot 插件不知道覆盖（它非常基本），因此如果您喜欢在 github 中提出问题，可以提出相关问题。项目中的 WAR 文件部署并运行（使用 java -jar）就好了，所以其他一切都正常。
