创建一个springboot工程最小化代码(json-lib的引入gradle方式)

   compile 'org.springframework.boot:spring-boot-starter-web:1.4.0.RELEASE'

   compile 'net.sf.json-lib:json-lib:2.4:jdk15'

   compile 'org.apache.httpcomponents:httpcore:4.4.10'
   compile 'org.apache.httpcomponents:httpmime:4.5.6'
   compile 'org.apache.httpcomponents:httpclient:4.5.6'
<!-- maven -->
<dependency>    
    <groupId>net.sf.json-lib</groupId>    
    <artifactId>json-lib</artifactId>    
    <version>2.4</version>    
    <classifier>jdk15</classifier>    
</dependency> 

最小代码的springboot工程:

settings.gradle:

/*
 * This settings file was generated by the Gradle 'init' task.
 *
 * The settings file is used to specify which projects to include in your build.
 * In a single project build this file can be empty or even removed.
 *
 * Detailed information about configuring a multi-project build in Gradle can be found
 * in the user guide at https://docs.gradle.org/4.3/userguide/multi_project_builds.html
 */

/*
// To declare projects as part of a multi-project build use the 'include' method
include 'shared'
include 'api'
include 'services:webservice'
*/

rootProject.name = 'testcase'

 

build.gradle

apply plugin: 'java-library'
apply plugin: 'org.springframework.boot'


buildscript {
    repositories {
        maven {
            name 'Aliyun Maven Repository'
            url "http://maven.aliyun.com/nexus/content/groups/public/"
        }
    }
    dependencies {

        classpath "io.spring.gradle:dependency-management-plugin:1.0.5.RELEASE"
    }
}
// In this section you declare where to find the dependencies of your project
repositories {
    maven {
        name 'Aliyun Maven Repository'
        url "http://maven.aliyun.com/nexus/content/groups/public/"
    }
    jcenter()
}


springBoot {
    executable = true
    mainClass = 'com.casetest.TestCaseBoot'
}

dependencies {
