思路：

        通过maven管理，将前后端分离两个项目合并打包成一个jar，成为一个单体项目。springboot在install或者package打包时，调动vue打包，vue自动install和build，将生成的dist复制到spring boot后端的resources下，完成合并打包。

项目结构：

itemsplus
    ─ items-springBoot
    ─ items-vue

配置：

1、在items-vue前端项目下新建pom.xml，无需添加标签配置，新建完成选中pom右击add到maven

<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">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.nokia.items</groupId>
    <artifactId>itemsplus</artifactId>
    <version>${global.version}</version><!--改成自己项目版本-->
    <relativePath>../../pom.xml</relativePath>
  </parent>
  <artifactId>items-vue</artifactId>
  <packaging>jar</packaging>
  <name>items-vue</name>
  <description>items-vue for itmesplus</description>

</project>

2、在itemsplus主pom配置exec版本

			    <plugin>
					<groupId>org.codehaus.mojo</groupId>
					<artifactId>exec-maven-plugin</artifactId>
					<version>3.0.0</version>
				</plugin>

3、 配置items-springBoot后端pom

<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">  
       <modelVersion>4.0.0</modelVersion>
         <parent>
             <groupId>com.nokia.itms</groupId>
             <artifactId>itemsplus</artifactId>
             <version>${global.version}</version>
             <relativePath>../../pom.xml</relativePath>
         </parent>
         <artifactId>items-springBoot</artifactId>
         <packaging>jar</packaging>

         <name>items-springBoot</name>
         <description>items-springBoot for itmsplus</description>

注意：

建议先参考vue通过maven自动打包成jar_码的的博客-CSDN博客_vue打包jar

        items-springBoot进行install或者package即可

        项目目录有变，修改pom中相应的目录路径

        注意配置vue的port和后端端口一致

        后端注意放开静态文件的访问
