--------------------

# 1-总体概述 #

## 1.1-版本信息 ##

*  SpringBoot 版本：1.5.9.RELEASE
 *  SpringCloud 版本：Dalston.SR1

## 1.2-案例说明 ##

以 Dept 部门模块做一个微服务的通用案例，Consumer 消费者(Client)通过 Rest 调用 Provider 提供者(Server)提供服务。

## 1.3-Maven 模块化 ##

简单的 Maven 模块结构是这样的：父项目(app-parent)聚合很多子项目(app-util、app-dao、app-service、app-web)。

**将案例拆分成如下模块：**

microservicecloud：父工程(Project)下带着 3 个子模块(Module)

*  microservicecloud-api（封装整体 Entity、接口、公共配置等）
 *  microservicecloud-provider-dept-8001（微服务服务提供者）
 *  microservicecloud-consumer-dept-80（微服务服务消费者）

# 2-搭建步骤 #

## 2.1-父工程 microservicecloud ##

**a、新建父工程 microservicecloud**  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3loajE5OTIwNDE3_size_16_color_FFFFFF_t_70]

**b、删除父工程 microservicecloud 中无用的 src 文件夹**  
![在这里插入图片描述][20210111105450196.png]  
**c、修改父工程 microservicecloud 中 pom.xml**

**切记 packaging 是 pom 模式**：定义 pom 类型，将后续各个子模块公共的 jar 包等统一提取出来，类似抽象父类 pom 文件。  
![在这里插入图片描述][20210111105637316.png]

## 2.2-公共模块 microservicecloud-api ##

**a、右击父工程 microservicecloud，新建子模块 microservicecloud-api**  
![在这里插入图片描述][20210111105831804.png]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3loajE5OTIwNDE3_size_16_color_FFFFFF_t_70 2]  
**b、查看父工程 microservicecloud 中 pom.xml 变化**  
![在这里插入图片描述][2021010814205099.png]  
**c、修改子模块 microservicecloud-api 中 pom.xml**

**d、修改子模块 microservicecloud-api，目录 /src/main/java 中新建包 com.atguigu.springcloud.entities**

**e、修改子模块 microservicecloud-api，包 com.atguigu.springcloud.entities 中新建类 Dept.java**

配合 Lombok 使用

package com.atguigu.springcloud.entities;
    
    import lombok.Data;
    import lombok.NoArgsConstructor;
    import lombok.experimental.Accessors;
    
    import java.io.Serializable;
    
    @Data
    @NoArgsConstructor
    @Accessors(chain = true)
    @SuppressWarnings("serial")
    public class Dept implements Serializable {// 必须序列化
        private Long deptno;// 主键
        private String dname;// 部门名称
        // 来自哪个数据库，因为微服务架构可以一个服务对应一个数据库，同一个信息被存储到不同数据库
        private String db_source;
    
        public Dept(String dname) {
            super();
            this.dname = dname;
        }
    }

**f、子模块 microservicecloud-api，执行 Maven 命令 mvn clean install**  
![在这里插入图片描述][20210111111225415.png]  
执行 mvn clean install 命令打包到 Maven 本地仓库，给其它模块引用达到通用目的。即需要用到部门实体的话，不用每个工程都定义一份，直接引用本模块即可。

## 2.3-提供者服务 microservicecloud-provider-dept-8001 ##

**a、新建 jdbc:mysql://localhost:3306/cloudDB01 数据库**

子模块 microservicecloud-provider-dept-8001 连接 jdbc:mysql://localhost:3306/cloudDB01 数据库。

DROP DATABASE IF EXISTS cloudDB01;
    CREATE DATABASE cloudDB01 CHARACTER SET UTF8;
    
    USE cloudDB01;
    CREATE TABLE dept (
    	deptno BIGINT NOT NULL PRIMARY KEY AUTO_INCREMENT,
    	dname VARCHAR(60),
    	db_source VARCHAR(60)
    );
     
    INSERT INTO dept(dname,db_source) VALUES('开发部',DATABASE());
    INSERT INTO dept(dname,db_source) VALUES('人事部',DATABASE());
    INSERT INTO dept(dname,db_source) VALUES('财务部',DATABASE());
    INSERT INTO dept(dname,db_source) VALUES('市场部',DATABASE());
    INSERT INTO dept(dname,db_source) VALUES('运维部',DATABASE());
     
    SELECT * FROM dept;

**b、右击父工程 microservicecloud，新建子模块 microservicecloud-provider-dept-8001**  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3loajE5OTIwNDE3_size_16_color_FFFFFF_t_70 3]

**a、右击父工程 microservicecloud，新建子模块 microservicecloud-consumer-dept-80**  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3loajE5OTIwNDE3_size_16_color_FFFFFF_t_70 4]  
**b、修改子模块 microservicecloud-consumer-dept-80 中 pom.xml**

**c、修改子模块 microservicecloud-consumer-dept-80，目录 /src/main/resources 中新建 application.yml**

server:
      port: 80

**d、修改子模块 microservicecloud-consumer-dept-80，目录 /src/main/java 中新建包 com.atguigu.springcloud.cfgbeans**

**e、修改子模块 microservicecloud-consumer-dept-80，包 com.atguigu.springcloud.cfgbeans 中新建类 ConfigBean.java**

类似 Spring 里面 applicationContext.xml 写的注入 Bean。

package com.atguigu.springcloud.cfgbeans;
    
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.web.client.RestTemplate;
    
    @Configuration
    public class ConfigBean {
        @Bean
        public RestTemplate getRestTemplate() {
            return new RestTemplate();
        }
    }

**RestTemplate 是什么？**

RestTemplate 提供了多种便捷访问远程 Http 服务的方法，是一种简单便捷的访问 Restful 服务模板类，是 Spring 提供的用于访问 Rest 服务的**客户端模板工具集**。

**RestTemplate 官网及使用**

*  官网：[https://docs.spring.io/spring-framework/docs/4.3.7.RELEASE/javadoc-api/org/springframework/web/client/RestTemplate.html][https_docs.spring.io_spring-framework_docs_4.3.7.RELEASE_javadoc-api_org_springframework_web_client_RestTemplate.html]
 *  **使用**：使用 RestTemplate 访问 Restful 接口非常的简单粗暴无脑(url, requestMap, ResponseBean.class)，这三个参数分别代表 Rest 请求地址、请求参数、Http 响应转换被转换成的对象类型。

**f、修改子模块 microservicecloud-consumer-dept-80，目录 /src/main/java 中新建包 com.atguigu.springcloud.controller**

**g、修改子模块 microservicecloud-consumer-dept-80，包 com.atguigu.springcloud.controller 中新建类 DeptController\_Consumer.java**

package com.atguigu.springcloud.controller;
    
    import com.atguigu.springcloud.entities.Dept;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    import org.springframework.web.client.RestTemplate;
    
    import java.util.List;
    
    @RestController
    public class DeptController_Consumer {
        private static final String REST_URL_PREFIX = "http://localhost:8001";
    
        @Autowired
        private RestTemplate restTemplate;
    
        @RequestMapping(value = "/consumer/dept/add")
        public boolean add(Dept dept) {
            return restTemplate.postForObject(REST_URL_PREFIX + "/dept/add", dept, Boolean.class);
        }
    
        @RequestMapping(value = "/consumer/dept/get/{id}")
        public Dept get(@PathVariable("id") Long id) {
            return restTemplate.getForObject(REST_URL_PREFIX + "/dept/get/" + id, Dept.class);
        }
    
        @SuppressWarnings("unchecked")
        @RequestMapping(value = "/consumer/dept/list")
        public List<Dept> list() {
            return restTemplate.getForObject(REST_URL_PREFIX + "/dept/list", List.class);
        }
    }

**h、修改子模块 microservicecloud-consumer-dept-80，包 com.atguigu.springcloud 中新建启动类 DeptConsumer80\_App.java**

package com.atguigu.springcloud;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication
    public class DeptConsumer80_App {
        public static void main(String[] args) {
            SpringApplication.run(DeptConsumer80_App.class, args);
        }
    }

**i、测试子模块 microservicecloud-consumer-dept-80**

*  启动子模块 microservicecloud-provider-dept-8001
 *  启动子模块 microservicecloud-consumer-dept-80
 *  [http://localhost/consumer/dept/get/2][http_localhost_consumer_dept_get_2]
