项目结构说明

结构说明：

changgou-common

公共模块用于引入公共依赖，工具包引用等。

changgou_gateway

网关模块，根据网站的规模和需要，可以将综合逻辑相关的服务用网关路由组合到一起。在这里还可以做鉴权和限流相关操作。

changgou_service

微服务模块，该模块用于存放所有独立的微服务工程。

changgou_service_api

对应工程的JavaBean实体类、Feign接口、以及Hystrix配置，该工程主要对外提供依赖。

changgou_transaction_fescar

分布式事务模块，将分布式事务抽取到该工程中，任何工程如需要使用分布式事务，只需依赖该工程即可。

changgou_web

web服务工程，对应功能模块如需要调用多个微服务，可以将他们写入到该模块中，例如网站后台、网站前台界面等。

删除src文件夹

二级父工程模块搭建

创建changgou_gateway、changgou_service、changgou_service_api、changgou_web工程，工程全部为pom工程，并将所有工程的src文件删除。

Eureka微服务搭建

（1）pom.xml依赖

创建模块changgou_eureka，pom.xml引入依赖

<?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>
        <artifactId>changgou-parent</artifactId>
        <groupId>com.changgou</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>

        </dependency>
    </dependencies>
</project>

（2） appliation.yml配置

创建配置文件application.yml

server:
  port: 7001
eureka:
  instance:
    hostname: 127.0.0.1
  client:
    register-with-eureka: false   #是否将自己注册到eureka中
    fetch-registry: false         #是否从eureka中获取信息
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

（3）启动类配置

创建包com.changgou 包下创建启动类EurekaApplication，代码如下：

package com.changgou;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class EurekaApplication {
    public static void main(String[] args) {
        SpringApplication.run(EurekaApplication.class,args);
    }
}

公共模块搭建

全局公共模块

（1）pom.xml依赖

创建公共子模块changgou_common，pom.xml引入依赖

<?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>
        <artifactId>changgou-parent</artifactId>
        <groupId>com.changgou</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>changgou-common</artifactId>

    <dependencies>
        <!--web的起步依赖-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!-- redis 使用-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>
        <!--eureka-client-->

            <artifactId>httpclient</artifactId>
        </dependency>
    </dependencies>
</project>

（2）常用对象

创建com.changgou.entity包，包下封装相关公共实体类、工具类等。

package com.changgou.entity;

/**
 * 返回结果实体类
 */
public class Result<T> {

    private boolean flag;//是否成功
    private Integer code;//返回码
    private String message;//返回消息

    private T data;//返回数据

    public Result(boolean flag, Integer code, String message, Object data) {
        this.flag = flag;
        this.code = code;
        this.message = message;
        this.data = (T)data;
    }

    public Result(boolean flag, Integer code, String message) {
        this.flag = flag;
        this.code = code;
        this.message = message;
    }

    public Result() {
        this.flag = true;
        this.code = StatusCode.OK;
        this.message = "执行成功";
    }

    //getter and setter..
}

建立类用于承载分页的数据结果

/**
 * 分页结果类
 */
public class PageResult<T> {

    private Long total;//总记录数
    private List<T> rows;//记录

    public PageResult(Long total, List<T> rows) {
        this.total = total;
        this.rows = rows;
    }

    public PageResult() {
    }

    //getter and setter ......
}

创建返回状态码实体类

/**
 * 返回码
 */
public class StatusCode {

    public static final int OK=20000;//成功
    public static final int ERROR =20001;//失败
    public static final int LOGINERROR =20002;//用户名或密码错误
    public static final int ACCESSERROR =20003;//权限不足
    public static final int REMOTEERROR =20004;//远程调用失败
    public static final int REPERROR =20005;//重复操作
}

数据访问公共模块搭建

这个公共模块是连接mysql数据库的公共微服务模块，所有需要连接mysql的微服务都继承自此工程。

创建公共模块changgou_common_db，pom文件引入依赖：

<?xml version="1.0" encoding="UTF-8"?>

            <artifactId>mapper-spring-boot-starter</artifactId>
            <version>2.0.4</version>
        </dependency>
        <!--MySQL数据库驱动-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>
        <!--mybatis分页插件-->
        <dependency>
            <groupId>com.github.pagehelper</groupId>
            <artifactId>pagehelper-spring-boot-starter</artifactId>
            <version>1.2.3</version>
        </dependency>
    </dependencies>
</project>

商品微服务搭建：

商品微服务API工程搭建：

（1）changgou_service_api 引入persistence-api和changgou-common的依赖

<dependencies>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-openfeign</artifactId>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>javax.persistence</groupId>
        <artifactId>persistence-api</artifactId>
        <version>1.0</version>
        <scope>compile</scope>
    </dependency>
</dependencies>

（2）changgou_service_api 下创建changgou_service_goods_api子模块并添加changgou-common模块依赖：

商品微服务工程搭建：

（1）changgou_service下创建changgou_service_goods子模块，pom.xml引入依赖：

<dependencies>
    <dependency>
        <groupId>com.changgou</groupId>
        <artifactId>changgou_common_db</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>
    <dependency>
        <groupId>com.changgou</groupId>
        <artifactId>changgou_service_goods_api</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
    </dependency>
</dependencies>

（2）创建配置文件application.yml

server:
  port: 18081
spring:
  application:
    name: goods
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://192.168.211.132:3306/changgou_goods?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
    username: root
    password: 123456
eureka:
  client:
    service-url:
      defaultZone: http://127.0.0.1:7001/eureka
  instance:
    prefer-ip-address: true
feign:
  hystrix:
    enabled: true
#hystrix 配置
hystrix:
  command:
    default:
      execution:
        isolation:
          thread:
            timeoutInMilliseconds: 10000
          strategy: SEMAPHORE

#mybatis的配置 可以不配置  需要整合通用mapper
#mybatis:
#  configuration:
#    map-underscore-to-camel-case: true
#  mapper-locations: classpath:mapper/*Mapper.xml
#  type-aliases-package: com.changgou.goods.pojo

（3）创建包com.changgou.goods 包下创建启动类

@SpringBootApplication
@EnableEurekaClient
@MapperScan(basePackages = {"com.changgou.goods.dao"})
public class GoodsApplication {
    public static void main(String[] args) {
        SpringApplication.run(GoodsApplication.class);
    }
}

注意：@MapperScan是tk.mybatis.spring.annotation包下的，用于扫描Mapper接口
