好些日子之前就在網(wǎng)上看見(jiàn)一篇文章，說(shuō)一個(gè)小后端想用 Vue 作前端技術(shù)結(jié)合 SpringBoot 后端作開(kāi)發(fā)，但又想方便點(diǎn)讓前端的工程能夠自己跑進(jìn) Jar 包里。很感興趣誒，于是就動(dòng)手跟著實(shí)現(xiàn)一遍。

原文：A Lovely Spring View: Spring Boot & Vue.js

原理實(shí)際是利用 frontend-maven-plugin 來(lái)調(diào)用 node ，不過(guò)這個(gè)插件有個(gè)好處，它是在工程的目錄下安裝 node，這樣能擺脫對(duì)本機(jī) node 的依賴，在很多地方進(jìn)行構(gòu)建。

起來(lái)先建一個(gè)普通的 SpringBoot 工程項(xiàng)目，然后普通地把 src/ 刪掉開(kāi)始建立子模塊。我是建立了 backend 和 frontend 兩個(gè)模塊。

springboot-vue/
    |- frontend/
    |   |- src/
    |   |   |- ...
    |   |- pom.xml
    |- backend/
    |   |- src/
    |   |   |- ...
    |   |- pom.xml
    |- pom.xml

根 pom ：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <relativePath/> <!-- lookup parent from repository -->

    </dependencies>
</project>

后端，backend 需要配置一下 maven-resource-plugin

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>springboot-vue</artifactId>
        <groupId>net.catten</groupId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>backend</artifactId>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <plugin>
                <artifactId>maven-resources-plugin</artifactId>
                <executions>
                    <execution>
                        <id>copy Vue frontend content</id>
                        <phase>generate-resources</phase>
                        <goals>
                            <goal>copy-resources</goal>
                        </goals>
                        <configuration>
                            <outputDirectory>src/main/resources/static</outputDirectory>
                            <overwrite>true</overwrite>
                            <resources>
                                <resource>
                                    <directory>
                                        ${project.parent.basedir}/frontend/dist
                                    </directory>
                                </resource>
                            </resources>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
</project>

對(duì)這個(gè)插件熟悉的就可以跳過(guò)下面說(shuō)明了。

其中 plugin 的 configuration 內(nèi)，outputDirectory 是指輸出的地方， resource 指從哪里復(fù)制文件，復(fù)制的文件當(dāng)然就是 webpack 打包出來(lái)的了。

前端，配置 frontend-maven-plugin

<?xml version="1.0" encoding="UTF-8"?>

         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>frontend</artifactId>

        <plugins>
            <plugin>

                <artifactId>frontend-maven-plugin</artifactId>
                <version>1.6</version>
                <executions>
                    <!-- Install our node and npm version to run npm/node scripts-->
                    <execution>
                        <id>install node and npm</id>
                        <goals>
                            <goal>install-node-and-npm</goal>
                        </goals>
                        <configuration>
                            <nodeVersion>v9.11.1</nodeVersion>
                        </configuration>
                    </execution>
                    <!-- Install all project dependencies -->
                    <execution>
                        <id>npm install</id>
                        <goals>
                            <goal>npm</goal>
                        </goals>
                        <!-- optional: default phase is "generate-resources" -->
                        <phase>generate-resources</phase>
                        <!-- Optional configuration which provides for running any npm command -->
                        <configuration>
                            <arguments>install</arguments>
                        </configuration>
                    </execution>
                    <!-- Build and minify static files -->
                    <execution>
                        <id>npm run build</id>
                        <goals>
                            <goal>npm</goal>
                        </goals>
                        <configuration>
                            <arguments>run build</arguments>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

</project>

這個(gè)基本上不用去動(dòng)，如果對(duì) nodeVersion 有要求可以修改一下。這里的配置是會(huì)在 generate-resources 的時(shí)候調(diào)用 npm run build ，實(shí)際拷貝資源文件的操作還是 backend 內(nèi)的插件做的，所以拷貝的源文件路徑需要和 webpack 的配置配合，按需修改 backend 的 configurations。
