spring-boot - Spring Boot Gradle 多模块项目找不到模板位置

问题描述

我正在使用 Gradle 管理我的项目，并且根项目中有 3 个模块（Spring Boot）。

每个模块在自定义模板位置都有自己的模板，/WEB-INF/templates/我在每个模块上设置了这些属性application.yml。

但是，当应用程序启动时出现警告日志

2021-09-16 22:53:39.153  WARN 17043 --- [  restartedMain] o.s.b.a.m.MustacheAutoConfiguration      : Cannot find template location: /WEB-INF/templates/ (please add some templates, check your Mustache configuration, or set spring.mustache.check-template-location=false)

这很奇怪，因为我独立运行应用程序，它不是作为多模块项目打开的项目，只是将项目作为单个项目打开，它运行良好。

这是我的 build.gradle

如果你们有任何解决这个问题的想法请告诉我谢谢

我发现了一些不同之处！当多模块项目运行时，它会检查是否存在作为模板位置的资源，/WEB-INF/templates/如下TemplateLocation.java所示

public boolean exists(ResourcePatternResolver resolver) {
        Assert.notNull(resolver, "Resolver must not be null");
        if (resolver.getResource(this.path).exists()) {
            return true;
        }
        try {
            return anyExists(resolver);
        }
        catch (IOException ex) {
            return false;
        }
    }

我在此检查处理时检查了根文件路径，另一方面，当我在单个模块项目上执行相同的工作时resolver.getResource('/').getFile()，它返回了一些临时目录，它返回了实际的项目目录/AppData/.../tomcat-docbase...D:\Java\...

我希望它可以成为解决问题的线索
