总结：

1.建module

2.改pom

3.写yml

4.主启动

5.业务类

1.建module

![590a1c8edfa1c1c5f72121bcba729d65.png][]

这里没有选骨架，可以根据自己情况选择

![d8e836417ab59e166dca1527368751d5.png][]

创建完成后回到父工程查看pom文件变化

gav pom放在最上面

2.改pom

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">

3.写yml

一定要有服务端口号和服务名称

server:

port: 8001

spring:

application:

name: cloud-payment-service

datasource:

type: com.alibaba.druid.pool.DruidDataSource

driver-class-name: org.gjt.mm.mysql.Driver

url: jdbc:mysql://localhost:3306/db2020?useUnicode=true&characterEncoding=utf-8&useSSL=false

username: root

password: root

mybatis:

mapperLocations: classpath:mapper/\*.xml

type-aliases-package: com.sunyan.springcloud.entity

4.主启动

![0df78072ad126a9ae467771a2554bd09.png][]

5.业务类

建表SQL

CREATE TABLE \`payment\`(

\`id\` BIGINT(20) NOT NULL AUTO\_INCREMENT COMMENT 'ID',

\`serial\` VARCHAR(20) DEFAULT '',

PRIMARY KEY(id)

)ENGINE=INNODB AUTO\_INCREMENT=1 DEFAULT CHARSET=utf8

entity

主实体Payment

dao

接口PaymentDao

![a1eda8ad0e3fb602721540f466333a3f.png][]

注意：建议加Mapper注解

mybatis的映射文件PaymentMapper.xml

路径：src/main/resources/mapper/PaymentMapper.xml

文件头

/p>

"http://mybatis.org/dtd/mybatis-3-mapper.dtd">

PaymentMapper.xml

/p>

"http://mybatis.org/dtd/mybatis-3-mapper.dtd">

insert into payment(serial) values (\#\{serial\});

select \* from payment where id = \#\{id\};

service

接口PaymentService

测试

浏览器一般不支持post，用postman

1.postman工具模拟

2.自测通过
