SpringBoot - 制作jar文件 - 在META-INF/spring.factories中找不到自动配置类

使用Intellij启动我的应用程序时一切正常.但是当我做了fatJar并执行时:

java -jar myapp.jar

我懂了:

16:37:44.194 [main] ERROR org.springframework.boot.SpringApplication - Application startup failed

看起来它没有在META-INF/spring.factories中找到自动配置类.如何添加此文件？这个文件的内容应该是什么？

我有同样的问题,只是解决了它.

起初我用它生成了胖罐maven-assembly-plugin,它创建了一个名为的文件mavenproject1-0.0.1-SNAPSHOT-jar-with-dependencies.jar.当我尝试运行它时,此文件提供了与您相同的问题.

我认为因为它是一个Spring Boot应用程序,所以你需要使用它们的插件.我将包装改为了spring-boot-maven-plugin,它创建了两个文件:mavenproject1-0.0.1-SNAPSHOT.jar和mavenproject1-0.0.1-SNAPSHOT.jar.original.只是尝试java -jar target/mavenproject1-0.0.1-SNAPSHOT.jar,它将有希望工作.:-)

作为参考,这是我的pom.xml:
