【springcloudalibaba】-支付微服務進行集羣搭建（zcw-demo）【十一】

前言

本篇博客主要是介紹我們支付微服務進行集羣搭建，支付微服務主要是對外提供接口服務，在這進行集羣搭建主要是方便其他服務使用。根據之前幾篇博客，已經編寫了支付服務，現在再創建一個支付服務。

支付微服務B

1.創建module

2.修改POM文件：


<dependencies>
        <!--eureka-client-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.1.10</version>
        </dependency>
        <!--mysql-connector-java-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>
        <!--jdbc-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <scope>runtime</scope>
            <optional>true</optional>
        </dependency>
        <!--引入自定義的api通用包，可以使用payment支付Entitiy-->
        <dependency>
            <groupId>com.zcw</groupId>
            <artifactId>cloud-api-commons</artifactId>
            <version>${project.version}</version>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
        </dependency>
    </dependencies>

3.修改YML文件

server:
  port: 8097

spring:
  application:
    name: cloud-provider-payment-zcw-service
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource   # 當前數據源操作類型
    driver-class-name: org.gjt.mm.mysql.Driver
    url: jdbc:mysql://localhost:3306/zcw20200509?useUnicode=true&characterEncoding=utf-8&useSSL=false
    username: root
    password: root

eureka:
  client:
    #表示是否將自己祖冊到EurekaServer默認爲true
    register-with-eureka: true
    #是否從EurekaServer抓取已有的註冊信息，默認爲true，單節點無所謂，集羣必須設置爲true，才能配合ribbon負載均衡
    fetchRegistry: true
    serviceUrl:
      #defaultZone:  http://server1:7001/eureka/
      defaultZone:  http://server2:7008/eureka/,http://server1:7001/eureka/
mybatis:
  mapper-locations: classpath:mapper/*.xml
  type-aliases-package: com.zcw.springcloud.entities # 所有entity別名類所在包

4.創建mapper類文件：


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.zcw.springcloud.dao.PaymentDao">
    <resultMap id="BaseResultMap" type="com.zcw.springcloud.entities.Payment">
        <id column="id" jdbcType="BIGINT" property="id" />
        <result column="serial" jdbcType="VARCHAR" property="serial" />
    </resultMap>
    <sql id="Base_Column_List">
    id, serial
  </sql>
    <insert id="create" parameterType="Payment" useGeneratedKeys="true" keyProperty="id">
        insert into payment(serial) values(#{serial});
    </insert>
    <select id="getPaymentById" parameterType="Long" resultMap="BaseResultMap">
        select * from payment where id=#{id};
    </select>

</mapper>
