一、项目内部依赖关系

项目的内部依赖关系表明的是：在coin-exchange该项目内部，我的那个模块需要依赖那个模块。

file

1.1在所有service 里面添加自己项目api的依赖

涉及的项目包含：

  • coin-admin
  • coin-member
  • coin-finance
  • coin-chan
  • coin-statistics
  • match-engine
  • exchange-engine
    在这些项目的service 里面均需要添加api的依赖。
    对于远程调用，我们暂时先不做依赖的管理

在coin-admin/admin-service 的pom.xml文件添加 api的依赖

    <dependencies>
        <dependency>
            <groupId>com.quantsmart</groupId>
            <artifactId>admin-api</artifactId>
            <version>1.0</version>
        </dependency>
    </dependencies>

1.2 打包依赖后的项目

在IDEA找到我们 coin-exchange 该父项目，点击install 即可打包所有的项目。

二、项目的外部依赖

file

2.1 通过parent引入springboot

在coin-exchange项目里面，添加如下：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.2.3.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

2.2 通过依赖管理导入springcloud

2.2.1定义版本号

    <properties>
        <java.version>1.8</java.version>
        <spring-cloud.version>Hoxton.SR3</spring-cloud.version>
    </properties>

2.2.2 依赖管理

<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>

2.3 通过依赖管理导入spring-cloud-alibaba

2.3.1定义版本号

<properties>
<java.version>1.8</java.version>
<com-alibaba-cloud.version>2.2.0.RELEASE</com-alibaba-cloud.version>
</properties>

2.3.2 依赖管理

<dependencyManagement>
    <dependencies>
     <dependency>
<groupId>com.alibaba.cloud</groupId>
      <artifactId>spring-cloud-alibaba-dependencies</artifactId>
      <version>${com-alibaba-cloud.version}</version>
      <type>pom</type>
      <scope>import</scope>
     </dependency>
</dependencies>
</dependencyManagement>

2.4 其他依赖的导入

其他依赖我们均采用依赖管理的方式来导入
注意：其他依赖具体的作用，我们在使用到时，再给大家说明。

2.4.1 版本号的定义

<properties>
        <java.version>1.8</java.version>

          </dependency>
      </dependencies>
    </dependencyManagement>

</project>

三、coin-exchange依赖

coin-exchang 是所有项目的父项目，在它里面添加依赖时需要谨慎，因为它的依赖会传递到我们所有的子项目里面。

我们在coin-exchange里面依赖：

<dependencies>
    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
    </dependency>
    <!-- https://mvnrepository.com/artifact/io.swagger/swagger-annotations -->
    <dependency>
        <groupId>io.swagger</groupId>
        <artifactId>swagger-annotations</artifactId>
    </dependency>
    <dependency>
        <groupId>com.baomidou</groupId>
        <artifactId>mybatis-plus-annotation</artifactId>
    </dependency>
    <!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-annotations -->
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-annotations</artifactId>
    </dependency>
</dependencies>

大家不难发现，我们仅仅依赖了一些注解而已。

可以看到，我们的根目录实际只依赖了四个依赖：

file

知识扩展：

Maven中dependencymanagement和dependency的区别：

简单来说：
dependencyManagement 里只是声明依赖，并不实现引入，而dependencies相对于dependencyManagement，所有声明在dependencies里的依赖都会自动引入，并默认被所有的子项目继承。

Maven 使用dependencyManagement 元素来提供了一种管理依赖版本号的方式。通常会在一个组织或者项目的最顶层的父POM 中看到dependencyManagement 元素。使用pom.xml 中的dependencyManagement 元素能让所有在子项目中引用一个依赖而不用显式的列出版本号。Maven 会沿着父子层次向上走，直到找到一个拥有dependencyManagement 元素的项目，然后它就会使用在这个dependencyManagement 元素中指定的版本号。

相对于dependencyManagement，所有声明在dependencies里的依赖都会自动引入，并默认被所有的子项目继承。

      </dependencies>
    </dependencyManagement>

</project>

四、coin-common的依赖

coin-common 以后将会让所有的xxx-service依赖，因此我们需要提取xxx-service里面所有的公共依赖。现在我们来思考一下，作为一个微服务或中台服务，都需要那些依赖：

①、服务注册

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>

②、配置文件拉取

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
</dependency>

③、服务保护（限流、熔断）

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
</dependency>

④、服务保护（鉴权）

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-oauth2</artifactId>
</dependency>

⑤、数据库的访问

<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-boot-starter</artifactId>
</dependency>
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
</dependency>

⑥、缓存的使用

<dependency>
    <groupId>com.alicp.jetcache</groupId>
    <artifactId>jetcache-starter-redis</artifactId>
</dependency>

⑦、工具类

<dependency>
    <groupId>io.springside</groupId>
    <artifactId>springside-utils</artifactId>
</dependency>

⑧、远程调用

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>

    </dependencies>
</project>

五、xxx-service的依赖

在所有的xxx-service 里面依赖coin-common

六、打包插件

我们的模块以后需要单独的运行起来，因此我们还需要添加一个打包插件：
file

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

涉及的项目包含：

  • coin-admin
  • coin-chan
  • coin-finance
  • coin-member
  • coin-statistics
  • coin-task
  • exchange-engine
  • match-engine

coin-exchange/exchange-engine/exchange-service/pom.xml 添加示例

<?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"

    <modelVersion>4.0.0</modelVersion>

        </dependency>
    </dependencies>
