cloud-provider-payment8001 微服务提供者Module模块
总结：
1.建module
2.改pom
3.写yml
4.主启动
5.业务类
1.建module
这里没有选骨架，可以根据自己情况选择
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

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
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
Json封装体CommonResult
dao
接口PaymentDao
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
<?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">
PaymentMapper.xml
<?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.sunyan.springcloud.dao.PaymentDao">
<insert id="create" parameterType="Payment" useGeneratedKeys="true" keyProperty="id">
insert into payment(serial) values (#{serial});
</insert>
<resultMap id="BaseResultMap" type="com.sunyan.springcloud.entity.Payment">
<id property="id" column="id" jdbcType="BIGINT"></id>
<id property="serial" column="serial" jdbcType="VARCHAR"></id>
</resultMap>
<select id="getPaymentById" parameterType="Long" resultMap="BaseResultMap">
select * from payment where id = #{id};
</select>
</mapper>
service
接口PaymentService
实现类
controller
测试
浏览器一般不支持post，用postman
1.postman工具模拟
2.自测通过
代码结构
