如何在Maven中使用Typescript配置Angular2应用程序？

我正在使用Maven在Angular 2 + Spring Boot应用程序中使用Typescript .ts文件。我运行npm install以获得依赖关系，并运行npm tsc通过exec-maven-plugin将.ts文件转换为.js 。

以下是我pom.xml中的插件部分。在我的应用程序中，pacakge.json，tsconfig.json和Types.json都在src / main / resources路径下，因此在该路径下运行npm任务

pom.xml

<parent>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-parent</artifactId>

                        <executable>npm</executable>
                        <arguments>

                            <argument>tsc</argument>

                    </configuration>
                    <goals>
                        <goal>exec</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

我的Angular2 + Spring Boot应用程序文件夹结构如下

src/main/resources
                  /app          - .ts and converted .js
                  /css
                  /images
                  /js           - systemjs.config.js is also placed here
                  /node_modules - generated by npm install and will include in war
                  /typings
                  application.properties
                  package.json
                  tsconfig.json
                  typings.json

src/main/webapp
               /WEB-INF
                       /jsp     - all .jsp files

在.jsp文件头部分，包含systemjs.config.js

<script type="text/javascript" src="webjars/zone.js/0.6.12/dist/zone.js"></script>
<script type="text/javascript" src="webjars/reflect-metadata/0.1.3/Reflect.js"></script>
<script type="text/javascript" src="webjars/systemjs/0.19.27/dist/system.js"></script>
<script type="text/javascript" src="js/systemjs.config.js"></script>

这也是我的WebMvcConfigurerAdapter代码到映射路径

@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;
    }
}

我想提到的一件事是，如果操作系统是Windows或Mac，则在eclipse上运行exec-maven-plugin会有一些漏洞。Linux（Ubuntu）看起来完全没有问题。在Windows或Mac上从eclipse运行构建时，问题是它不理解npm命令并尝试查找此类文件，即使maven构建在终端或命令窗口上完全正常。

为了解决这个问题，我做了一些调整。对于Mac，如下所示在/ usr / bin路径下为node和npm进行符号链接。但是不允许修改/ usr / bin，因此我是在通过恢复磁盘重新启动后完成的

lrwxr-xr-x     1 root   wheel        17 May 22 03:01 node -> ../local/bin/node
lrwxr-xr-x     1 root   wheel        44 May 22 02:50 npm -> ../local/lib/node_modules/npm/bin/npm-cli.js

对于Windows，我在如下所示的系统路径下制作了node.bat和npm.bat文件。完成此操作后，在Windows 10上的Eclipse和Command窗口中，maven的构建都完全正常。
