idea gradle+springboot 构建多项目 运行 打包

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
