春季靴子Maven战争叠加 [英] Spring Boot & Maven war overlay

问题描述

我正在与一个Maven多模块一起使用，这取决于另一场战争.

I'm working with a Maven multi module with a war depending on an other war.

Spring Boot Webapp依赖于仅提供html文件的基本Webapp.

The Spring Boot webapp depends on a basic webapp that only serves html files.

当我运行Spring Boot应用程序时，我能够从主Web应用程序(Spring Boot之一)访问服务和html，但是无法从依赖项战争中访问html文件(404).但是这些html文件在Spring Boot webapp war中打包得很好...

When I run the Spring Boot app, I'm able to access services and html from the main webapp (the Spring Boot one) but I can't access the html files from the dependency war (404). But these html files are well packaged in the Spring Boot webapp war...

这是一个显示问题的项目:

Here is a project that show the problem:
https://github.com/cthiebault/spring-boot-war-overlays

该项目有2个战争模块:

This project has 2 war modules:

• dependency-webapp :仅提供html(/dependency/index.html)的基本webapp
• main-webapp :Spring Boot Webapp(摘自Spring Guides

• dependency-webapp: basic webapp serving just html (/dependency/index.html)
• main-webapp: Spring Boot webapp (copied from Spring Guides gs-serving-web-content). This webapp has a dependency on dependency-webapp.

这是主Web应用程序pom.xml:

Here is the main-webapp pom.xml:

运行网络应用程序:

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

当我尝试访问html页面时，以下是日志:

有什么问题的想法吗?

推荐答案

Spring Boot插件不了解覆盖(这是非常基本的)，因此如果您喜欢github，可以提出有关此问题.项目中的WAR文件可以正常部署和运行(使用java -jar)，因此其他所有功能都可以正常工作.

The Spring Boot plugin doesn't know about the overlay (it's pretty basic), so you can raise an issue about that if you like in github. The WAR file from your project deploys and runs (with java -jar) just fine though, so everything else is working.
