如何使用Spring Boot Angular 2项目中的Gradle build将静态文件添加到jar

提问于

我有一个Spring Boot Angular 2项目 . 我想将它部署到Heroku . 我能够运行npm构建，然后手动将生成的文件复制到公共文件夹（src / resources / public），然后运行后端构建 . 我想要做的是设置一个gradle构建，它将立即完成所有这些 . 到目前为止我所拥有的是一个gradle构建，它将构建前端，构建后端，但是在生成jar之前它不会复制静态文件 . 由于jar不包含所述静态文件，因此它不适用于Heroku .

这是项目文件夹结构：

root
 backend
  src/main/java
  src/main/resources
 frontend
  --> angular files go here
 build/libs -> where the JAR file goes

gradle构建文件：

buildscript {
repositories {
    mavenCentral()
}
dependencies {
    // spring
    classpath('org.springframework.boot:spring-boot-gradle-plugin:1.5.2.RELEASE')
    classpath('org.springframework:springloaded:1.2.6.RELEASE')
    }
}

plugins {
    id "com.moowork.node" version "1.2.0"
}

// gradle wrapper
task wrapper(type: Wrapper) {
    gradleVersion = '3.4'
}

// configure gradle-node-plugin
node {
    version = '8.1.4'
    npmVersion = '5.0.3'
    download = true
    workDir = file("${project.projectDir}/node")
    nodeModulesDir = file("${project.projectDir}/")
}

// clean node/node_modules/dist
task npmClean(type: Delete) {
    final def webDir = "${rootDir}/frontend"
    delete "${webDir}/node"
    delete "${webDir}/node_modules"
    delete "${webDir}/dist"
    delete "${webDir}/coverage"
    delete "${rootDir}/backend/src/main/resources/public"
}

// clean task for npm

task copyFiles {
    doLast {
        copy {
            from "${rootDir}/frontend/dist"
            into "${rootDir}/backend/src/main/resources/public"
        }
    }    
}

// build task for npm
task frontendBuild {}
frontendBuild.dependsOn(npm_install)
frontendBuild.dependsOn(npm_run_build)

npm_install {
  args = ['--prefix', './frontend']
}

npm_run_build {
  args = ['--prefix', './frontend']
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'

sourceSets {
    main {
        java {
            srcDirs = ['backend/src/main/java']
        }
        resources {
            srcDirs = ['backend/src/main/resources']
        }
    }
}

copyFiles.dependsOn(frontendBuild);
compileJava.dependsOn(frontendBuild);

task backendBuild {}
backendBuild.dependsOn(compileJava)
backendBuild.dependsOn(jar)

jar.dependsOn(copyFiles)

repositories {
    mavenCentral()
}

eclipse {
    classpath {
         containers.remove('org.eclipse.jdt.launching.JRE_CONTAINER')
         containers('org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8')
    }
}

idea {
    module {
        inheritOutputDirs = false
        outputDir = file("${buildDir}/classes/main/")
    }
}

jar {
    baseName = 'expense-splitter'
    version = '0.0.1'
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

configurations {
    dev
}

dependencies {
    // spring
    compile('org.springframework.boot:spring-boot-starter-web:1.5.2.RELEASE')
    compile('org.springframework.boot:spring-boot-starter-data-jpa:1.5.2.RELEASE')
    compile('org.springframework.boot:spring-boot-starter-security:1.5.2.RELEASE')

    compile('org.apache.commons:commons-lang3:3.3.2')

    // to make hibernate handle java 8 date and time types correctly
    // it's marked as deprecated but we need to keep it until
    // spring boot jpa starts using hibernate 5.2
    compile('org.hibernate:hibernate-java8:5.1.0.Final')

    // json web tokens
    compile ('io.jsonwebtoken:jjwt:0.7.0')

    compile 'mysql:mysql-connector-java'
    // google gson
    compile('com.google.code.gson:gson:2.8.0')
    // jackson - parsing of java 8 date and time types
    compile('com.fasterxml.jackson.datatype:jackson-datatype-jsr310:2.8.7')


    // spring dev tools
    dev('org.springframework.boot:spring-boot-devtools:1.5.2.RELEASE')

    // testing
    testCompile('org.springframework.boot:spring-boot-starter-test:1.5.2.RELEASE')
}

// run spring boot app
bootRun {
    //addResources = true
    classpath = sourceSets.main.runtimeClasspath + configurations.dev
    jvmArgs = ["-Xdebug -agentlib:jdwp=transport=dt_socket,address=8080,server=y,suspend=n"]
}

// run all task
task runAll {}
runAll.dependsOn(bootRun)

    尝试不同的方法 . 而不是手动复制资源，告诉Gradle当它处理JAR的资源时，还要考虑 frontend/dist/ 中的内容：

    processResources {
    from ('frontend/dist/') {
        into 'public'
    }
}

    这应该导致JAR包含 public/ 目录，其中包含 frontend/dist/ 的内容 .

    Gradle configuration for Spring Boot 1.5\2.x + Angular 2-6

    子文件夹中的角度 frontend

    Frontend module

    箱子 build.gradle ：

    plugins {
  id "com.moowork.node" version "1.2.0"
}

node {
  version = '8.11.3'
  npmVersion = '5.6.0'
  download = true
  workDir = file("${project.buildDir}/node")
  nodeModulesDir = file("${project.projectDir}")
}

task build(type: NpmTask) {
  args = ['run', 'build']
}

build.dependsOn(npm_install)

    Note for Angular 6

    将 angular.json 中的 outputPath 值更新为'dist'

    Backend module

    编辑后端模块的 build.gradle ：

    Spring Boot 2.X：

    bootJar {
    archiveName = "yourapp.jar"
    mainClassName = 'com.company.app.Application'

    from('frontend/dist') {
        into 'static'
    }
}

    Spring Boot 1.5.X：

    jar {
    archiveName = "yourapp.jar"
    manifest {
        attributes 'Main-Class': 'com.company.app.Application'
    }
    from('frontend/dist') {
        into 'static'
    }
    from {
        configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
    }
}

    最后执行 bootRepackage 或 bootJar 任务并检查 builds/libs 中的结果
