1、前端Angular，后端Spring Boot

2、在后端pom.xml文件中增加以下内容：

<build>
        <resources>
            <resource>
                <directory>${project.basedir}/src/main/resources</directory>
            </resource>
            <resource>
                <directory>${project.build.directory}/generated-resources</directory>
            </resource>
        </resources>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <plugin>
                <groupId>com.github.eirslett</groupId>
                <artifactId>frontend-maven-plugin</artifactId>
                <version>1.6</version>
                <configuration>
                    <nodeVersion>v8.8.1</nodeVersion>
                </configuration>
                <executions>
                    <execution>
                        <id>install-npm</id>
                        <goals>
                            <goal>install-node-and-npm</goal>
                        </goals>
                    </execution>
                    <execution>
                        <id>npm-install</id>
                        <goals>
                            <goal>npm</goal>
                        </goals>
                    </execution>
                    <execution>
                        <id>npm-build</id>
                        <goals>
                            <goal>npm</goal>
                        </goals>
                        <configuration>
                            <arguments>run-script build</arguments>
                        </configuration>
                    </execution>
                    <execution>
                        <id>npm-test</id>
                        <goals>
                            <goal>npm</goal>
                        </goals>
                        <configuration>
                            <arguments>run-script e2e</arguments>
                        </configuration>
                        <phase>test</phase>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

3、增加缺少的jar包，例如：

npm install ng2-completer --save

4、修改输出目录:

"outDir": "target/classes/static",

5、拷贝主页面

从文件夹拷贝到文件夹
