微服务拆分作业参考

依赖

user-service的pom.xml文件内容如下：

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

1.3.启动类

在user-service中的com.hmall.user包下创建启动类：

package com.hmall.user;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@MapperScan("com.hmall.user.mapper")
@SpringBootApplication
public class UserApplication {
    public static void main(String[] args) {
        SpringApplication.run(UserApplication.class, args);
    }
}

 

1.4.配置文件

从hm-service项目中复制3个yaml配置文件到user-service的resource目录。

其中application-dev.yaml和application-local.yaml保持不变。application.yaml如下：

server:
  port: 8084
spring:
  application:
    name: user-service # 服务名称
  profiles:
    active: dev
  datasource:
    url: jdbc:mysql://${hm.db.host}:3306/hm-user?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&serverTimezone=Asia/Shanghai
    driver-class-name: com.mysql.cj.jdbc.Driver
    username: root
    password: ${hm.db.pw}
  cloud:
    nacos:
      server-addr: 192.168.150.101 # nacos地址
mybatis-plus:
  configuration:
    default-enum-type-handler: com.baomidou.mybatisplus.core.handlers.MybatisEnumTypeHandler
  global-config:
    db-config:
      update-strategy: not_null
      id-type: auto
logging:
  level:
    com.hmall: debug
  pattern:
    dateformat: HH:mm:ss:SSS
  file:
    path: "logs/${spring.application.name}"
knife4j:
  enable: true
  openapi:
    title: 用户服务接口文档
    description: "信息"
    email: zhanghuyi@itcast.cn
    concat: 虎哥
    url: https://www.itcast.cn
    version: v1.0.0
    group:
      default:
        group-name: default
        api-rule: package
        api-rule-resources:
          - com.hmall.user.controller
hm:
  jwt:
    location: classpath:hmall.jks
    alias: hmall
    password: hmall123
    tokenTTL: 30m

 

将hm-service下的hmall.jks文件拷贝到user-service下的resources目录，这是JWT加密的秘钥文件：

 

1.5.代码

复制hm-service中所有与user、address、jwt有关的代码，最终项目结构如下：
