Question

我的Spring Boot应用程序包含Java部分和Angular部分。 Angular部分（带有index.html等）生成到文件夹src / main / resources / static中。工作良好。我注意到在构建最终的JAR时，经常会丢失静态部分。

为什么？如何将static / HTML部分放入最终的Spring Boot JAR中？

我的pom.xml的部分如下所示。所有不重要的部分（例如单元测试等）都将被删除。

<build>
    ... 
    <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.6.0</version>
    <executions>
      <execution>
        <id>npm install</id>
        <goals>
          <goal>exec</goal>
        </goals>
        <phase>initialize</phase>
        <configuration>
          <executable>npm</executable>
          <arguments>
            <argument>install</argument>
          </arguments>

我正在使用validate阶段将静态角度资源复制到spring：

mvn clean install

使用父pom从Spring项目中拆分角度：

<modules>
    <module>phs-frontend</module>
    <module>phs-frontend-web</module>
</modules>

其中phs-frontend项目是一个带有pom文件和maven clean插件的有角项目：

<build>
    <plugins>
        <plugin>
            <artifactId>maven-clean-plugin</artifactId>
            <version>2.5</version>
            <configuration>
                <filesets>
                    <fileset>
                        <directory>dist</directory>
                        <includes>
                            <include>*</include>
                        </includes>
                    </fileset>
                </filesets>
            </configuration>
        </plugin>

        <plugin>

                        <nodeVersion>v6.10.3</nodeVersion>
                        <npmVersion>5.6.0</npmVersion>
                    </configuration>
                </execution>

                <execution>

                    </goals>
                    <configuration>
                        <arguments>install</arguments>
                    </configuration>
                </execution>

                <execution>
                    <id>npm run build</id>
                    <goals>
                        <goal>npm</goal>

                    <configuration>

                    </configuration>
                </execution>

            </executions>
        </plugin>

    </plugins>

phs-frontend-web是Spring项目：

Answer 2

谢谢@Carlos Cavero！你为我指明了正确的方向。非常感谢！

问题在于npm构建是在“编译”阶段完成的。在某些机器上，Java代码的“编译”阶段是在用Angular的“ npm build”进行“编译”之前完成的。

解决方案是将Angular（打字稿）npm阶段放在之前编译阶段。即：在“生成资源”阶段。它不可能是“验证”阶段，因为该阶段是在“安装”和“ npm安装”之前完成的。

现在这是正确的Angular / npm构建阶段。

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.6.0</version>
    <executions>
      <execution>
        <id>npm install</id>
        <goals>
          <goal>exec</goal>
        </goals>
        <phase>initialize</phase>
        <configuration>
          <executable>npm</executable>
          <arguments>
            <argument>install</argument>
          </arguments>
        </configuration>
