是否可以将 AngularJs 包含到带有 Gradle 的项目中

Question

我知道可以将 AngularJs 与 Maven 一起包含到 Spring 项目中，但如何将它包含在 Gradle 中？

查看 gradle 存储库，我发现没有 AngularJs 条目。也许可以使用 Gradle 从 Maven 存储库中获取它？但是如何做到这一点。

Answer 1

尽管在下面的讨论中证明通过 gradle 下载 angular 没有意义，但可以使用以下代码来完成：

repositories {
   ivy {
      name = 'AngularJS'
      url = 'https://code.angularjs.org/'
      layout 'pattern', {
         artifact '[revision]/[module](.[classifier]).[ext]'
      }
   }
}

configurations {
   angular
}

dependencies {
   angular group: 'angular', name: 'angular', version: '1.3.9', classifier: 'min', ext: 'js'
}

task fetch(type: Copy) {
   from configurations.angular
   into 'src/main/webapp/js'
   rename {
      'angular.js'
   }
}

Answer 2

查看webjars，我强烈推荐它。

我刚刚在 Maven 和 Gradle 项目中使用过它。
基本上它正是我们所需要的，大量的前端项目和框架打包在 jars 中。

• 将此依赖项添加到您的 build.gradle 脚本中：

  compile 'org.webjars:angularjs:1.3.14'

• 转到文档部分以获取 Spring 的快速设置指南

• 在脚本中包含 angular.js 或 jar 中的其他模块，例如本地资源

  <script src="where-you-exposed-webjars/angular/1.3.14/angular.js"></script>

• 或者可选地从require.js脚本中要求它

可能会迟到，但请结帐https://github.com/gharia/spring-boot-angular。 这是使用资产管道的带有角度 JS 的 Spring Boot 项目。

编辑：

使用this gradle plugin，我们可以轻松管理客户端依赖项，无论是 npm 还是 bower 或 GIT。请参阅下面的示例 build.gradle，其中我在 clientDependencies 中包含了 Angular 的几个依赖项。

buildscript {
    repositories {
        mavenCentral()
        mavenLocal()
        maven { url "https://repo.grails.org/grails/core" }
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.3.3.RELEASE")
        classpath("org.codehaus.groovy:groovy:2.4.6")
        classpath("gradle.plugin.com.boxfuse.client:flyway-release:4.0")
    }
}

plugins {
    id 'com.craigburke.client-dependencies' version '1.0.0-RC2'
}

apply plugin: 'groovy'
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'
apply plugin: 'war'

jar {
    baseName = 'boot-demo'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
    mavenLocal()
    maven { url "https://repo.grails.org/grails/core" }
    jcenter()
    maven { url "http://repo.spring.io/libs-snapshot" }
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

configurations {
    providedRuntime
}

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
    providedRuntime("org.springframework.boot:spring-boot-starter-tomcat")
    compile("org.springframework.boot:spring-boot-starter-actuator")
    compile("org.springframework.boot:spring-boot-starter-data-jpa")

    compile("org.codehaus.groovy:groovy")
    testCompile("org.springframework.boot:spring-boot-starter-test")
    testCompile("junit:junit")
}

task wrapper(type: Wrapper) {
    gradleVersion = '2.3'
}

clientDependencies {


    npm {
        'angular'('1.5.x', into: 'angular') {
            include 'angular.js'
            include 'angular.min.js'
        }
        'angular-resource'('1.5.x', into: 'angular') {
            include 'angular-resource.js'
            include 'angular-resource.min.js'
        }
        'angular-mocks'('1.5.x', into: 'angular') {
            include 'angular-mocks.js'
            include 'angular-mocks.min.js'
        }
        'angular-route'('1.5.x', into: 'angular'){
            include 'angular-route.js'
            include 'angular-route.min.js'
        }
        'angular-animate'('1.5.x', into: 'angular') {
            include 'angular-animate.js'
            include 'angular-animate.min.js'
        }               

    }

}

assets {
  minifyJs = true
  minifyCss = true
}

Answer 4

我有 AngularJS 2 + Spring Boot 应用程序和 Gradle。我使用 typescript（.ts 文件）和 npm（node js 包管理器）。所以我正在运行 npm install 来生成 node_modules 和 npm run tsc 来将打字稿翻译成 javascript。不过，我仍然使用一些 webjar，基本上依赖项在构建时由 npm 任务收集，并由 systemjs.config.js 文件连接

下面是我的文件夹结构

/src/main/java
/src/main/resources
                   /app           - .ts files and .js translated from .ts
                   /css
                   /js            - systemjs.config.js
                   /node_modules  - generated by npm install
                   /typings       - generated by npm install
                   package.json
                   tsconfig.json
                   typings.json
/src/main/webapp/WEB-INF/jsp      - .jsp files

这是我的 build.gradle 文件并添加两个自定义任务（npmInstall 和 npmRunTsc）来运行 npm 任务

build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.3.5.RELEASE")
        classpath("org.flywaydb:flyway-gradle-plugin:3.2.1")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'
apply plugin: 'war'

war {
    baseName = 'my-angular-app'
    version =  '1.0'
    manifest {
        attributes 'Main-Class': 'com.my.Application'
    }
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    mavenLocal()
    mavenCentral()
}

task npmInstall(type:Exec) {
    workingDir 'src/main/resources'
    commandLine 'npm', 'install'
    standardOutput = new ByteArrayOutputStream()
    ext.output = {
        return standardOutput.toString()
    }
}

task npmRunTsc(type:Exec) {
    workingDir 'src/main/resources'
    commandLine 'npm', 'run', 'tsc'
    standardOutput = new ByteArrayOutputStream()
    ext.output = {
        return standardOutput.toString()
    }
}

dependencies {
    // tag::jetty[]
    compile("org.springframework.boot:spring-boot-starter-web")
    compile("org.springframework.boot:spring-boot-starter-tomcat",
            "org.springframework.boot:spring-boot-starter-data-jpa",
            "org.springframework.boot:spring-boot-starter-actuator",
            "org.springframework.boot:spring-boot-starter-security",
            "org.springframework.boot:spring-boot-starter-batch",
            "org.springframework.cloud:spring-cloud-starter-config:1.0.3.RELEASE",
            "org.springframework.cloud:spring-cloud-config-client:1.0.3.RELEASE",
            "com.google.code.gson:gson",
            "commons-lang:commons-lang:2.6",
            "commons-collections:commons-collections",
            "commons-codec:commons-codec:1.10",
            "commons-io:commons-io:2.4",
            "com.h2database:h2",
            "org.hibernate:hibernate-core",
            "org.hibernate:hibernate-entitymanager",
            "org.webjars:datatables:1.10.5",
            "org.webjars:datatables-plugins:ca6ec50",
            "javax.servlet:jstl",
            "org.apache.tomcat.embed:tomcat-embed-jasper",
            "org.quartz-scheduler:quartz:2.2.1",
            "org.jolokia:jolokia-core",
            "org.aspectj:aspectjweaver",
            "org.perf4j:perf4j:0.9.16",
            "commons-jexl:commons-jexl:1.1",
            "cglib:cglib:3.2.1",
            "org.flywaydb:flyway-core",
            )
    providedRuntime("org.springframework.boot:spring-boot-starter-tomcat")
    testCompile("junit:junit",
                "org.springframework:spring-test",
                "org.springframework.boot:spring-boot-starter-test",
                "org.powermock:powermock-api-mockito:1.6.2",
                "org.powermock:powermock-module-junit4:1.6.2",
                )
}

task wrapper(type: Wrapper) {
    gradleVersion = '1.11'
}

当我运行 gradle 构建过程时，我运行如下

$ gradle clean npmInstall npmRunTsc test bootRepackage

我可以使用 AngularJS 教程中显示的相同 systemjs.config.js

systemjs.config.js

(function(global) {
  // map tells the System loader where to look for things
  var map = {
    'app':                        'app', // 'dist',
    'rxjs':                       'node_modules/rxjs',
    'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api',
    '@angular':                   'node_modules/@angular'
  };
  // packages tells the System loader how to load when no filename and/or no extension
  var packages = {
    'app':                        { main: 'main.js',  defaultExtension: 'js' },
    'rxjs':                       { defaultExtension: 'js' },
    'angular2-in-memory-web-api': { defaultExtension: 'js' },
  };
  var packageNames = [
    '@angular/common',
    '@angular/compiler',
    '@angular/core',
    '@angular/http',
    '@angular/platform-browser',
    '@angular/platform-browser-dynamic',
    '@angular/router',
    '@angular/router-deprecated',
    '@angular/testing',
    '@angular/upgrade',
  ];
  // add package entries for angular packages in the form '@angular/common': { main: 'index.js', defaultExtension: 'js' }
  packageNames.forEach(function(pkgName) {
    packages[pkgName] = { main: 'index.js', defaultExtension: 'js' };
  });
  var config = {
    map: map,
    packages: packages
  }
  System.config(config);
})(this);

在 .jsp 文件中，我将 systemjs.config.js 包含在 head 部分中

<script type="text/javascript" src="node_modules/zone.js/dist/zone.js"></script>
<script type="text/javascript" src="node_modules/reflect-metadata/Reflect.js"></script>
<script type="text/javascript" src="node_modules/systemjs/dist/system.src.js"></script>
<script type="text/javascript" src="js/systemjs.config.js"></script>

最后，整理一下我在 Spring WebMvcConfigurerAdapter 上的上下文路径

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.my.controller")
public class WebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        if (!registry.hasMappingForPattern("/webjars/**")) {
            registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
        }
        if (!registry.hasMappingForPattern("/images/**")) {
            registry.addResourceHandler("/images/**").addResourceLocations("classpath:/images/");
        }
        if (!registry.hasMappingForPattern("/css/**")) {
            registry.addResourceHandler("/css/**").addResourceLocations("classpath:/css/");
        }
        if (!registry.hasMappingForPattern("/js/**")) {
            registry.addResourceHandler("/js/**").addResourceLocations("classpath:/js/");
        }
        if (!registry.hasMappingForPattern("/app/**")) {
            registry.addResourceHandler("/app/**").addResourceLocations("classpath:/app/");
        }
        if (!registry.hasMappingForPattern("/node_modules/**")) {
            registry.addResourceHandler("/node_modules/**").addResourceLocations("classpath:/node_modules/");
        }
    }

    @Bean
    public InternalResourceViewResolver internalViewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("/WEB-INF/jsp/");
        viewResolver.setSuffix(".jsp");
        viewResolver.setOrder(1);
        return viewResolver;
    }
}
