springboot瘦身

鉴于网上很多代码都是同一篇文章转载过来的基本验证无效，以下是经过项目测试后可用的方案

jar.doFirst {
    manifest {
        attributes 'Class-Path': configurations.compileClasspath.files.collect { "lib"+File.separator+"$it.name" }.join(' ')
        attributes 'Main-Class':  'com.halower.dynamicdb.DynamicDatasourceLab'
    }
}

task thinJar(type: Copy) {
    def dir = new File( "$buildDir"+File.separator+"libs");
    if(!dir.exists()) dir.mkdir()
    dir.eachDir{d -> d.delete()}
    from configurations.compileClasspath
    into "$buildDir"+File.separator+"libs"+File.separator+"lib"
    print('依赖包提取完成')
}

jar.enabled = true
bootJar.enabled = false


bootJar {
    dependsOn thinJar
}
