用Idea 2019.3+和Gradle5.2.1+ 構建 SpringBoot多項目(三)

現在開始項目大多數默認使用SpringBoot，下面配置SpringBoot多項目，

之前都是用Maven管理項目依賴，使用https://start.spring.io/ 初始化一個Gradle類型項目作爲參考，配置如下：

主要參考文件build.gradle

plugins {
	id 'org.springframework.boot' version '2.2.5.RELEASE'
	id 'io.spring.dependency-management' version '1.0.9.RELEASE'
	id 'java'
}

group = 'org.hazulnut'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'

repositories {
	mavenCentral()
}

dependencies {
	implementation 'org.springframework.boot:spring-boot-starter-actuator'
	implementation 'org.springframework.boot:spring-boot-starter-web'
	testImplementation('org.springframework.boot:spring-boot-starter-test') {
		exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
	}
}

test {
	useJUnitPlatform()
}

先配置公共repositories

allprojects {
    apply plugin: 'java'

    group 'org.hazulnut'
    version '1.0-SNAPSHOT'
    setProperty('sourceCompatibility', 1.8)
    setProperty('targetCompatibility', 1.8)

    repositories {
        maven { url 'https://maven.aliyun.com/repository/public/' }
        maven { url 'https://maven.aliyun.com/repository/central' }
        maven { url 'https://maven.aliyun.com/repository/jcenter'}
        maven { url 'https://maven.aliyun.com/repository/spring/' }
        maven { url 'https://maven.aliyun.com/repository/spring-plugin'}
        maven { url 'https://maven.aliyun.com/repository/gradle-plugin'}
        mavenLocal()
        mavenCentral()
        jcenter()
    }
}

選一個model項目配置依賴：

plugins {
    id 'org.springframework.boot' version '2.2.5.RELEASE'
    id 'io.spring.dependency-management' version '1.0.9.RELEASE'
    id 'java'
}


dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-actuator'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }
}

build正常，logback項目下依賴可以正常引入：

項目都是依賴於SpringBoot，把公共配置放到root項目中配置，子項目去掉公共配置：

root項目的build.Gradle文件

plugins {
    id 'org.springframework.boot' version '2.2.5.RELEASE'
    id 'io.spring.dependency-management' version '1.0.9.RELEASE'
    id 'java'
}

allprojects {
    apply plugin: 'java'

    group 'org.hazulnut'
    version '1.0-SNAPSHOT'
    setProperty('sourceCompatibility', 1.8)
    setProperty('targetCompatibility', 1.8)

    repositories {
        maven { url 'https://maven.aliyun.com/repository/public/' }
        maven { url 'https://maven.aliyun.com/repository/central' }
        maven { url 'https://maven.aliyun.com/repository/jcenter'}
        maven { url 'https://maven.aliyun.com/repository/spring/' }
        maven { url 'https://maven.aliyun.com/repository/spring-plugin'}
        maven { url 'https://maven.aliyun.com/repository/gradle-plugin'}
        mavenLocal()
        mavenCentral()
        jcenter()
    }
}

subprojects {
    apply plugin: 'org.springframework.boot'
    apply plugin: 'io.spring.dependency-management'

    dependencies {
        implementation 'org.springframework.boot:spring-boot-starter-actuator'
        implementation 'org.springframework.boot:spring-boot-starter-web'
        testImplementation('org.springframework.boot:spring-boot-starter-test') {
            exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
        }
    }
}

子項目build.Gradle文件

從上圖紅框標註可以看到所有子項目都正常引入公共依賴。

注意：root項目的build.Gradle中的plugins配置塊不能缺少，否則報下圖所示錯誤。

至此 Gradle5.2.1+ 構建 SpringBoot多項目完成。
