1. 首先的话需要配置build.gradle

buildscript {
        ext {
            springBootVersion = '2.2.4.RELEASE'
        }
    
        tasks.withType(JavaCompile) {
            options.encoding = "UTF-8"
        }
    
        repositories {
            maven {
                url 'http://maven.aliyun.com/nexus/content/groups/public'
            }
        }
        dependencies {
            // 引入 gradle 插件
            classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        }
    }
    
    allprojects {
        apply plugin: 'java'
        apply plugin: 'eclipse'
        apply plugin: 'idea'
        apply plugin: 'jacoco'
        //注意这里使用org.springframework.boot的bootJar插件因此要引入这个插件
        apply plugin: 'org.springframework.boot'
    
        sourceCompatibility = '1.8'
        compileJava.options.encoding = 'UTF-8'
        compileTestJava.options.encoding = 'UFT8'
        repositories {
            maven {
                url 'http://maven.aliyun.com/nexus/content/groups/public'
            }
        }
        dependencies {
            implementation "org.springframework.boot:spring-boot-starter-web:${springBootVersion}"
            testImplementation "org.springframework.boot:spring-boot-starter-test:${springBootVersion}"
            testCompile group: 'junit', name: 'junit', version: '4.12'
            
            implementation group: 'mysql', name: 'mysql-connector-java', version: '8.0.18'
    
            implementation group: 'org.mybatis.spring.boot', name: 'mybatis-spring-boot-starter', version: '2.1.2'
    
    //        implementation files('lib/demo.main.jar')
    
        }
    }
    // Main-Class的目录 必须有的
    jar {
        String someString = ''
        configurations.runtime.each {someString = someString + " lib//"+it.name}
        manifest {
            attributes 'Main-Class': 'com.xu.Application'
            attributes 'Class-Path': someString
        }
    }

2. 使用gradle 的build 的命令进行打包

3. jar包会生成在项目根目录的 \\build\\libs 下

通过命令行执行 java -jar ×××.jar

执行功能，可以正常访问，**执行java -jar 的时候需要你当前的环境有java环境**
