## idea maven 搭建springcloud项目 ##

**新建一个maven什么骨架都不用**

**新建的maven父项目不写代码，所以删掉src文件夹**

引入依赖

<parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.2.5.RELEASE</version>
        </parent>
        
        <properties>
            <java.version>1.8</java.version>
            <spring.cloud.version>Hoxton.SR6</spring.cloud.version>
        </properties>
        
        <dependencyManagement>
            <dependencies>
                <dependency>
                    <groupId>org.springframework.cloud</groupId>
                    <artifactId>spring-cloud-dependencies</artifactId>
                    <version>${spring.cloud.version}</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
            </dependencies>
        </dependencyManagement>

**然后就是建立公共的项目，基于java，所以用quickstart骨架**

**然后选定父项目**  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0hlbGxvd29ybGRfcGFuZw_size_16_color_FFFFFF_t_70_pic_center 1]  
**pom文件删除不必要的代码**  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0hlbGxvd29ybGRfcGFuZw_size_16_color_FFFFFF_t_70_pic_center 2]  
**commons以后主要是放置公共实体类以及公共工具类以及公共依赖，所以不需要启动类，以及test**  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0hlbGxvd29ybGRfcGFuZw_size_16_color_FFFFFF_t_70_pic_center 3]  
**然后按照commons创建方式 随意 新建两个服务 （user服务，产品服务）**  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0hlbGxvd29ybGRfcGFuZw_size_16_color_FFFFFF_t_70_pic_center 4]  
**现在为了写入口类，需要引入springboot启动依赖（当然，应该写在commons里面）**

**然后这里是公共的服务，其他的服务需要引入**

**依赖被引入了，去开启入口类注解**

然后就是建resource文件夹以及下面的application.properties文件，然后转换成Resource root文件夹

**user服务跟prod服务一样**  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0hlbGxvd29ybGRfcGFuZw_size_16_color_FFFFFF_t_70_pic_center 9]  
由于删掉了junit依赖，所以暂时先把test删掉  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0hlbGxvd29ybGRfcGFuZw_size_16_color_FFFFFF_t_70_pic_center 10]  
给application.properties配置个服务端口，然后启动入口类

**报错**

file >>> setting

如果报错了：nstall (default-cli) on project kai-commons: The packaging for this project did not assign a file to；错误: 找不到或无法加载主类 org.com.kai.UserApplication，多clean install一下commons  
**现在把两个服务注册到consul注册中心**
