一、简介

技术	版本
Spring Cloud版本	Hoxton.SR1
Spring Boot版本	2.2.2RELEASE
Cloud Alibaba版本	2.1.0.RELEASE

SpringCloud的版本

Spring Cloud 采用了英国伦敦地铁站的名称来命名，并由地铁站名称字母A-Z依次类推的形式来发布迭代版本SpringCloud是一个由许多子项目组成的综合项目，各子项目有不同的发布节奏。为了管理SpringCloud与各子项目的版本依赖关系，发布了一个清单，其中包括了某个SpringCloud版本对应的子项目版本。为了避免SpringCloud版本号与子项目版本号混淆，SpringCloud版本采用了名称而非版本号的命名，这些版本的名字采用了伦敦地铁站的名字，根据字母表的顺序来对应版本时间顺序。例如Angel是第一个版本, Brixton是第二个版本。当SpringCloud的发布内容积累到临界点或者一个重大BUG被解决后，会发布一个"service releases"版本，简称SRX版本，比如Greenwich.SR2就是SpringCloud发布的Greenwich版本的第2个SRX版本。

2、关于Cloud各种组件的停更/升级/替换

官网：https://cloud.spring.io/spring-cloud-static/Hoxton.SR1/reference/htmlsingle/

官网：https://docs.spring.io/spring-boot/docs/2.2.2.RELEASE/reference/htmlsingle/

Spring Cloud中文文档: https://www.bookstack.cn/read/spring-cloud-docs/docs-index.md

升级后:

3、微服务架构编码构建(cloud-provider-payment8001)

3.1 pom文件

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

    </dependencies>


</project>

3.2 改yml文件

server:
  port: 8001


spring:
  application:
    name: cloud-payment-service



  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/springcloud?useUnicode=true&characterEncoding=utf-8&useSSL=false
    username: root
    password: root



mybatis:
  mapper-locations: classpath:mapper/*.xml
  type-aliases-package: com.yyds.springcloud.entities

3.3 主启动

package com.yyds.springcloud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;


@SpringBootApplication
public class PaymentMain8001 
    public static void main(String[] args) 
        SpringApplication.run(PaymentMain8001.class, args);
        System.out.println("*******************PaymentMain8001启动成功********************");

3.4 业务类

3.4.1 dao及mapper.xml

package com.yyds.springcloud.dao;

import com.yyds.springcloud.entities.Payment;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;

@Mapper
public interface PaymentDao 

    int create(Payment  payment);


    Payment getPaymentById(@Param("id") Long id);

<?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.yyds.springcloud.dao.PaymentDao">

    <resultMap id="BaseResultMap" type="payment">
        <result column="id" property="id"/>
        <result column="serial" property="serial"/>
    </resultMap>

    <insert id="create" parameterType="Payment" useGeneratedKeys="true" keyProperty="id">
        insert into payment (serial) value (#serial);
    </insert>


   <select id="getPaymentById" parameterType="Long" resultMap="BaseResultMap">
       select * from payment where id = #id
   </select>

</mapper>

3.4.2 service

package com.yyds.springcloud.service;

import com.yyds.springcloud.entities.Payment;
import org.apache.ibatis.annotations.Param;

public interface PaymentService 
     int create(Payment payment);
     Payment getPaymentById(@Param("id") Long id);

package com.yyds.springcloud.service.impl;

@Service

    @Override
    public int create(Payment payment) 
        return paymentDao.create(payment);
    

    @Override
    public Payment getPaymentById(Long id) 
        return paymentDao.getPaymentById(id);

3.4.3 controller

package com.yyds.springcloud.controller;

import com.yyds.springcloud.entities.CommonResult;
import com.yyds.springcloud.entities.Payment;
import com.yyds.springcloud.service.PaymentService;
import lombok.extern.slf4j.Slf4j;

    @PostMapping("/create")
    public CommonResult<Payment> create(@RequestBody  Payment payment)
        int result = paymentService.create(payment);
        if(result > 0)
            return new CommonResult(200,"插入数据库成功",result);
        else 
            return new CommonResult(444,"插入数据库失败",null);
        
    

    @GetMapping("/get/id")
    public CommonResult<Payment> getPaymentById(@PathVariable("id") Long id)
        Payment payment = paymentService.getPaymentById(id);
