一 可执行和可引用区别

SpringBoot项目内置了Maven代码管理，可以方便我们快捷生成可执行jar,无论是windows还是linux环境，可以简单使用java -jar这种命令是执行jar文件，但是可引用是无法完成的，boot-dev文件并不运行时文件添加在libs文件中，这也是可执行和可引用的区别。

二 Gradle代码管理生成可引用Jar

    id 'java'

tasks.withType(JavaCompile) {
    options.encoding = "UTF-8"
}
tasks.withType(Javadoc) {
    options.encoding = 'UTF-8'
}
tasks.withType(Test) {
    systemProperty "file.encoding", "UTF-8"
