我有同样的问题，只是解决了。
最初，我是使用生成胖子的
maven-assembly-plugin，该胖子创建了一个名为的文件
mavenproject1-0.0.1-SNAPSHOT-jar-with-dependencies.jar。与我尝试运行该文件时提到的问题相同。
我认为，因为它是Spring Boot应用程序，所以你需要使用它们的插件。我将包装更改为，spring-boot-maven-plugin并生成了两个文件：
mavenproject1-0.0.1-SNAPSHOT.jar和
mavenproject1-0.0.1-SNAPSHOT.jar.original。只需尝试
java -jar target/mavenproject1-0.0.1-SNAPSHOT.jar，它将有望工作。
供参考，这是我的
