我创建了一个Angular 2前端Application.and创建了一个连接到DB的Java Rest WS后端应用程序。
Angular 2 App的My Folder结构如下 -
我的Java Maven Web应用程序结构如下 -
我想知道如何将这两个应用程序集成到一个只生成一个war文件的应用程序中。
这是我做的: -
目录结构(ng app文件夹休息除外是标准的Maven结构。)
ngfirst
├── pom.xml
├── src
│ └── main
│ ├── java
│ ├── resources
│ ├── webapp
│ └── ngapp
角部
在终端打开ngapp文件夹并输入ng init命令来初始化节点和npm配置,结果将是一个简单的Angular2示例应用程序将ngapp文件夹中的以下目录结构: -
├── angular-cli.json
├── e2e
├── karma.conf.js
├── node_modules
├── package.json
├── protractor.conf.js
├── README.md
├── tslint.json
├── src
├── app
├── assets
├── environments
├── favicon.ico
├── index.html
├── main.ts
├── polyfills.ts
├── styles.css
├── test.ts
└── tsconfig.json
这个结构是Angular等效的Maven项目结构,而src目录是Angular Application的源代码,就像maven build命令在目标文件夹中生成它的输出一样,ng build命令在dist文件夹中生成它的输出。
为了在Maven生成的WAR中打包生成的Angular应用程序,修改构建配置以将输出文件夹从dist更改为webapp,打开angular-cli.json文件并修改其outDir,如下所示: -
"outDir": "../webapp/ng"
此时,ng build命令将在ngfirst / src / main / webapp文件夹的ng目录中生成内置的Angular Application。
Maven部分
打开pom.xml并配置以下三个maven插件: -
这是它应该是这样的: -
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.3</version>
<configuration>
<excludes>
<exclude>ngapp/**</exclude>

<argument>--base-href=/ngfirst/ng/</argument>
</arguments>
</configuration>
<goals>
<goal>exec</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
构建Maven项目(以及Angular App)
在项目根文件夹ngfirst中打开终端并运行mvn package命令,这将在目标文件夹中生成WAR文件(ngfirst.war)。
在容器中部署ngfirst.war,在浏览器中打开http://localhost:8080/ngfirst/ng/index.html。 (如果需要,调整主机名和端口)
如果一切顺利,你应该看到app工作!在浏览器中,这是Angular Application在工作!!
JSP预处理
我们可以利用Angular应用程序利用JSP技术的动态配置和页面呈现功能,Angular SPA作为常规HTML页面由Java容器提供服务,在这种情况下是index.html,如果我们将JSP Engine配置为预处理html文件,那么所有JSP魔术都可以包含在Angular SPA页面中,只需在web.xml中包含以下内容即可
<servlet-mapping>
<servlet-name>jsp</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
保存,重建maven项目,部署WAR和瞧!
我的方面我有一个叫做prj-angular的角度源的maven模块,另一个叫做prj-war的战争应用程序。
第一个prj angular建立:
npm install
和ng build
(感谢@J_Dev!)dist/
然后,第二个prj_war构建:
按照我使用的相应插件配置进行操作:

有趣的是,我上周做了这个!
使用Netbeans 8.1和Tomcat servlet版本8.0.27

我建议让两个应用程序分开,这样你就有了模块化。这样您就可以在不影响服务的情况下更改Angular App,反之亦然。第二,你的apache / nginx可以更快地从Angular而不是Tomcat(例如)传递你的js和html。但是如果你仍然想把Angular应用程序放在战争中,那么模式就是所有的web资源都在src / main / webapp中。
