spring_boot打jar包及打包错误的解决⽅法
问题产⽣及解决
对于刚接⼿spring_boot的⼈，可能会感觉到很茫然⽆措，看到书上写的spring_boot是直接打包成jar包，使⽤java -jar *运⾏。然⽽却不知道该怎么打包。⽽创建spring_boot以后在pom⽂件中会安装spring_boot打包插件，此时我们会看到如下⼏个选项：pom⽂件内容如下：
<?xml version="1.0" encoding="UTF-8"?>

在idea的右侧我们会看如下选项
如果此时我们直接点击repackage，则打包时会出现如下错误：
Process finished with exit code 1
正确的打包⽅法是：
直接使⽤maven的package命令，即可完成打包，若有新的内容添加，可以使⽤spring-boot-maven-plugin的repackage命令.详细步骤如下图：
