SpringBoot + Gradle 多模块项目构建、运行、打包

工具： IDEA

一、在IDEA中使用工具创建SpringBoot + Gradle的父工程

new -> project -> Spring Initializr  -> type选项选中Gradle Project(其他视情况填写)

父工程 : demo-springboot-gradle

二、在父工程下新建两个模块 web、dao

右键单击父工程 new -> module -> Spring Initializr -> type选项选中Gradle Project(其他视情况填写)

创建module的最后一步要注意，子模块最好在父工程的目录下，避免不必要的麻烦

三、删除dao子模块下的所有.java文件 、 删除父工程src文件

四、在dao子模块下创建两个类，用于测试Student 和 StudentService

public class Student {
    
        private Integer id;
        private String name;
    
        public Integer getId() {
            return id;
        }
    
        public void setId(Integer id) {
            this.id = id;
        }
    
        public String getName() {
            return name;
        }
    
        public void setName(String name) {
            this.name = name;
        }
    }

@Component
    public class StudentService {
    
        public Student query(){
            Student student = new Student();
            student.setId(1);
            student.setName("嘿");
            return student;
        }
    
    }

五、在web子模块下创建一个接口类StudentController

@RestController
    public class StudentController {
    
        @Autowired
        private StudentService studentService;
    
        @GetMapping("/hello")
        public Student hello(){
            return studentService.query();
        }
    }

六、dao子模块的bulid.gradle

group 'com.zeke'
    version '1.0-SNAPSHOT'
    
    apply plugin: 'java'
    
    sourceCompatibility = 1.8
    
    repositories {
        mavenCentral()
    }
    
    dependencies {
        testCompile group: 'junit', name: 'junit', version: '4.12'
    }

七、web子模块的bulid.gradle

buildscript {
    	ext {
    		springBootVersion = '1.5.3.RELEASE'
    	}
    	repositories {
    		mavenCentral()
    	}
    	dependencies {
    		classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    	}
    }
    
    apply plugin: 'java'
    apply plugin: 'idea'
    apply plugin: 'org.springframework.boot'
    apply plugin: 'war'
    
    version = '0.0.1-SNAPSHOT'
    sourceCompatibility = 1.8
    
    repositories {
    	mavenCentral()
    }
    
    configurations {
    	providedRuntime
    }
    
    dependencies {
    	compile('org.springframework.boot:spring-boot-starter-thymeleaf')
    	compile('org.springframework.boot:spring-boot-starter-web')
    //	providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
    	testCompile('org.springframework.boot:spring-boot-starter-test')
    }

八、父工程bulid.gradle

allprojects {
    	apply plugin: 'java'
    	group 'com.zeke'
    	version = '1.0'
    	sourceCompatibility = 1.8
    	targetCompatibility = 1.8
    }
    
    
    subprojects {
    	ext {
    //        slf4jVersion = '1.7.7'
    		springVersion = '4.3.8.RELEASE'
    		hibernateVersion = '4.3.1.Final'
    	}
    	[compileJava, compileTestJava, javadoc]*.options*.encoding = 'UTF-8'
    	repositories {
    		mavenCentral()
    	}
    	configurations {
    		//compile.exclude module: 'commons-logging'
    		all*.exclude module: 'commons-logging'
    	}
    	dependencies {
    		compile(
    				'redis.clients:jedis:2.9.0',
    				'org.slf4j:slf4j-api:1.7.25',
    				'ch.qos.logback:logback-core:1.1.11',
    				'ch.qos.logback:logback-classic:1.1.11',
    
    //                "org.slf4j:jcl-over-slf4j:${slf4jVersion}",
    //                "org.slf4j:slf4j-log4j12:${slf4jVersion}",
    				"org.springframework:spring-context:$springVersion",
    //                "org.springframework:spring-orm:$springVersion",
    //                "org.springframework:spring-tx:$springVersion",
    //                "org.springframework.data:spring-data-jpa:1.5.2.RELEASE",
    //                "org.hibernate:hibernate-entitymanager:$hibernateVersion",
    //                "c3p0:c3p0:0.9.1.2",
    				"mysql:mysql-connector-java:5.1.35",
    //                "commons-fileupload:commons-fileupload:1.3.1",
    				"com.fasterxml.jackson.core:jackson-databind:2.3.1"
    		)
    		testCompile(
    				"org.springframework:spring-test:$springVersion",
    				"junit:junit:4.12"
    		)
    	}
    }
    
    project(':dao') {
    
    }
    project(':web') {
    	apply plugin: "war"
    	dependencies {
    		compile project(":dao")
    		compile(
    				'org.springframework.boot:spring-boot-starter-thymeleaf',
    				'org.springframework.boot:spring-boot-starter-web'
    		)
    		testCompile(
    				'org.springframework.boot:spring-boot-starter-test'
    		)
    //        providedCompile(
    //                "javax.servlet:javax.servlet-api:3.1.0",
    //                "javax.servlet.jsp:jsp-api:2.2.1-b03",
    //                "javax.servlet.jsp.jstl:javax.servlet.jsp.jstl-api:1.2.1"
    //        )
    	}
    	processResources{
    		/* 从'$projectDir/src/main/java'目录下复制文件到'WEB-INF/classes'目录下覆盖原有同名文件*/
    		from("$projectDir/src/main/java")
    	}
    
    	/*自定义任务用于将当前子项目的java类打成jar包,此jar包不包含resources下的文件*/
    	def jarArchiveName="${project.name}-${version}.jar"
    	task jarWithoutResources(type: Jar) {
    		from sourceSets.main.output.classesDir
    		archiveName jarArchiveName
    	}
    
    	/*重写war任务:*/
    	war {
    		dependsOn jarWithoutResources
    		/* classpath排除sourceSets.main.output.classesDir目录,加入jarWithoutResources打出来的jar包 */
    		classpath = classpath.minus(files(sourceSets.main.output.classesDir)).plus(files("$buildDir/$libsDirName/$jarArchiveName"))
    	}
    	/*打印编译运行类路径*/
    	task jarPath << {
    		println configurations.compile.asPath
    	}
    }
    
    /*从子项目拷贝War任务生成的压缩包到根项目的build/explodedDist目录*/
    task explodedDist(type: Copy) {
    	into "$buildDir/explodedDist"
    	subprojects {
    		from tasks.withType(War)
    	}
    }

九、启动web子模块的application启动类，访问localhost:8080/hello

十、打包：

在父工程目录下输入命令 gradle build

取出 web子模块下 build -> libs -> web-1.0.jar

java -jar 执行即可访问
