[/code]1、项目用到了什么spring-boot的版本，就用spring-boot的工具进行打包。这点很重要呢例如v<version>1.3.0.M1</version>机器里面装了很多版本，一定要找对才行。[插入]配置MavenBuild-RunConfigurations如下图所示其中Goals:位置为org.apache.maven.plugins:maven-jar-plugin:2.5:jarorg.springframework.boot:spring-boot-maven-plugin:1.3.0.M1:repackage必须选择先maven后spring-boot-maven这个是有先后顺序的呢。不这样搞不行。成功的话会生成如下图所示：这两个缺一不可部。源代码：
