springcloud脚手架搭建（1）maven与docker

作者: 东方不喵 | 来源:发表于2019-07-25 00:06 被阅读0次

    微服务项目主要需要分为 模型层，业务层，网关层。而springcloud+maven构建项目时，往往需要 抽象父级maven项目和子maven项目。本章主要描述maven父子项目构建时候需要的注意点
    github https://github.com/oldguys/SpringCloudOldguyDemo

    模块：
    -commom: micro services app 常用基础类
-generator: 自动建表 + mybatis mapper.xml 文件创建
-auth: 授权
    - default-auth-server: Token,权限认证
-clients:
    - auth-client: 接入认证和授权的入口
    - log-client: 接入日志的入口
-gate: 网关
-module-api: 模型层，实体以及微服务调用service抽象
-modules: micro services app
    - log-server: 日志服务器( webflux + mongodb)
    - multi-datasource: 多数据库 mybatis示例
    - base: 通用示例及基础业务

    step1：最顶层模块 spring-cloud-oldguy 所有项目的通用模块，在此层主要配置项目通用的内容

            <artifactId>persistence-api</artifactId>
            <version>1.0</version>

        </dependency>

    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

</project>

    其中需要注意点

    1. springcloud项目 默认构建都会配置插件
            <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>

    此插件在模型层构建的时候，由于模型层只是提供通用的实体，接口，常量等，不具备SpringBoot启动条件，此时编译会报错。需要将此模块替换 为

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>

    此时只会走默认maven项目编译。

    1. 需要引入子项目，如果不引入，则在 mvn package的时候，不会编译。
        <modules>
        <module>oldguy-module-api</module>
        <module>oldguy-clients</module>
        <module>oldguy-generator</module>
        <module>oldguy-common</module>
        <module>oldguy-modules</module>
        <module>oldguy-auth</module>
        <module>oldguy-gate</module>
    </modules>
    1. 全局环境变量，配置完成之后，子maven项目引用的时候可以直接调用。
        <properties>
        <java.version>1.8</java.version>
        <spring-cloud.version>2.1.5.RELEASE</spring-cloud.version>
        <nacos.version>0.2.1.RELEASE</nacos.version>
        <swagger.version>2.7.0</swagger.version>
        <swagger-bootstrap-ui.version>1.9.4</swagger-bootstrap-ui.version>
        <mybatis-plus.version>3.0.5</mybatis-plus.version>
        <mysql-driver.version>5.1.47</mysql-driver.version>
        <druid.version>1.1.12</druid.version>
        <skipTests>true</skipTests>
    </properties>
    1. 配置打包类型，默认为jar 但是抽象层不需要打包，则需要修改为pom
        <packaging>pom</packaging>

    step2：模型层 oldguy-module-api 构建

    <?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">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>com.example.oldguy</groupId>
        <artifactId>spring-cloud-oldguy</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>

    <packaging>pom</packaging>

    <groupId>com.example.oldguy</groupId>
    <artifactId>oldguy-module-api</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>oldguy-module-api</name>

    <modules>
        <module>oldguy-workflow-api</module>
        <module>oldguy-base-api</module>
        <module>oldguy-log-api</module>
        <module>oldguy-common-api</module>
        <module>oldguy-auth-api</module>
    </modules>

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-openfeign</artifactId>
            <version>2.1.1.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.hibernate.validator</groupId>
            <artifactId>hibernate-validator</artifactId>
        </dependency>
    </dependencies>

</project>
    1. 继承父maven项目
        <parent>
        <groupId>com.example.oldguy</groupId>
        <artifactId>spring-cloud-oldguy</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>

    注意：其中被 省略的 <build></build> <dependency></dependency>会默认继承父级的

    step3：配置抽象模型层 oldguy-common-api

    <?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">
    <modelVersion>4.0.0</modelVersion>

    <parent>
        <groupId>com.example.oldguy</groupId>
        <artifactId>oldguy-module-api</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>

    <groupId>com.example.oldguy</groupId>
    <artifactId>oldguy-common-api</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>oldguy-common-api</name>
    <description>Demo project for Spring Boot</description>

</project>

    注意，此处不能使用<packaging>pom</packaging>，此层需要提供公共抽象类给其他模块，需要编译层 jar

    step4: 权限认证模型 oldguy-auth-api

    <?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">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>com.example.oldguy</groupId>
        <artifactId>oldguy-module-api</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>
    <groupId>com.example.oldguy</groupId>
    <artifactId>oldguy-auth-api</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>oldguy-auth-api</name>

    <description>Demo project for Spring Boot</description>

    <dependencies>
        <dependency>
            <groupId>com.example.oldguy</groupId>
            <artifactId>oldguy-common-api</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>
    </dependencies>
</project>
    1. 此处调用前面的通用模型层,引用整套系统的通用基类
           <dependency>
           <groupId>com.example.oldguy</groupId>
           <artifactId>oldguy-common-api</artifactId>
           <version>0.0.1-SNAPSHOT</version>
       </dependency>
    以上完成了模型层的构建，接下来是clients层

    step5：clients层，clients层主要用于做集成功能，如类似于SpringBoot的@Enable* 此类型的注解，抽象到此模块下，

    <?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">
   <modelVersion>4.0.0</modelVersion>
   <parent>
       <groupId>com.example.oldguy</groupId>
       <artifactId>spring-cloud-oldguy</artifactId>
       <version>0.0.1-SNAPSHOT</version>
   </parent>

   <packaging>pom</packaging>

   <groupId>com.example.oldguy</groupId>
   <artifactId>oldguy-clients</artifactId>
   <version>0.0.1-SNAPSHOT</version>
   <name>oldguy-clients</name>
   <description>Demo project for Spring Boot</description>

   <modules>
       <module>oldguy-mybatis-plus-client</module>
       <module>oldguy-nacos-client</module>
       <module>oldguy-auth-client</module>
       <module>oldguy-log-client</module>
   </modules>

</project>

    step6：auth-client 授权认证client，用于各个微服务app集成 认证中心，配置通用拦截器

    <?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">
   <modelVersion>4.0.0</modelVersion>
   <parent>
       <groupId>com.example.oldguy</groupId>
       <artifactId>oldguy-clients</artifactId>
       <version>0.0.1-SNAPSHOT</version>
   </parent>

   <groupId>com.example.oldguy</groupId>
   <artifactId>oldguy-auth-client</artifactId>
   <version>0.0.1-SNAPSHOT</version>
   <name>oldguy-auth-client</name>
   <description>Demo project for Spring Boot</description>

   <dependencies>
       <dependency>
           <groupId>com.example.oldguy</groupId>
           <artifactId>oldguy-auth-api</artifactId>
           <version>0.0.1-SNAPSHOT</version>
       </dependency>
       <dependency>
           <groupId>org.springframework</groupId>
           <artifactId>spring-webmvc</artifactId>
           <version>5.1.8.RELEASE</version>
           <scope>compile</scope>
       </dependency>
       <dependency>
           <groupId>org.apache.tomcat.embed</groupId>
           <artifactId>tomcat-embed-core</artifactId>
       </dependency>
   </dependencies>

</project>

    此处开始由其他层引用模型层 oldguy-auth-api

    step6：微服务App 通用层 ，此处主要为app的各种通用工具类

    <?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>
    <groupId>com.example.oldguy</groupId>
    <artifactId>oldguy-common</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>oldguy-common</name>
    <description>Demo project for Spring Boot</description>

    <dependencies>

            <scope>compile</scope>
        </dependency>
    </dependencies>

</project>
    以上完成了通用集成模块介绍和抽象工具模块介绍，下面为示例app 配置

    step7：认证中心构建

    1. 抽象认证服务层

           </plugin>
       </plugins>
   </build>

</project>

    1) 配置springboot插件
    此处需要配置springboot插件，因为生成的jar为springboot项目，不配置会抛找不到app.js 异常。

    <plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
</plugin>

    2) 配置docker插件

              <plugin>
              <groupId>com.spotify</groupId>
              <artifactId>docker-maven-plugin</artifactId>
              <version>0.4.11</version>
              <configuration>
                  <imageName>${project.artifactId}</imageName>
                  <dockerDirectory>src/main/docker</dockerDirectory>
                  <resources>
                      <resource>
                          <targetPath>/</targetPath>
                          <directory>${project.build.directory}</directory>
                          <include>${project.build.finalName}.jar</include>
                      </resource>
                  </resources>
              </configuration>
          </plugin>

    配置 Dockefile

    #运行此项目还需要基于java镜像
FROM java:8
#将本地文件夹挂载到当前容器
VOLUME /tmp
#拷贝文件到容器，注意这里的jar包是事先准备好的一个演示Cloud的jar项目，需要放在Dockerfile同样的目录下
ADD oldguy-default-auth-server-0.0.1-SNAPSHOT.jar app.jar
RUN ["/bin/bash","-c","touch /app.jar"]
#指定JAVA 环境变量
ENV JAVA_HOME /jdk/jre
ENV PATH $PATH:$JAVA_HOME/bin
ENV CLASSPATH .:$JAVA_HOME/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
#开放8761端口
EXPOSE 9010
#配置容器启动后执行的命令
ENTRYPOINT ["java","-jar","/app.jar"]

    配置 docker-compose.yml

    version: '3'
services:
 oldguy-gate:
   image: oldguy-gate:latest
   restart: always
   volumes:
     - /etc/localtime:/etc/localtime
     - /home/dc-ui/volume/data:/data
   ports:
     - 9010:9010
   environment:
     - PROFILES=router,sit
     - NACOS_ADDR=192.168.62.129:8848
     - LOG_LEVEL=info

    以上完成springcloud maven构建

    测试效果

    step1: 上传项目到centos /usr/workspace/SpringCloudOldguyDemo

    step2: mvn clean package

    mvn clean package

    step3 : cd /usr/workspace/SpringCloudOldguyDemo/oldguy-gate
    mvn docker:build

    mvn docker:build

    查看镜像是否存在


    docker images

    使用docker compose 启动
    docker-compose up


    docker-compose up
