第33-34周 Spring Cloud电商实战

一、Eureka-server模块开发

1、引入依赖

父项目依赖：cloud-mall-practice

1. springboot的父项目依赖
2. springboot的启动类
3. springboot的测类类
4. 对外访问的web依赖
5. swagger依赖
6. springcloud的管理依赖
7. idea整合maven插件
8. mybatisplus代码自动生成依赖

子模块依赖：cloud-mall-eureka-server

  <dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-eureka-server</artifactId></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build>

2、配置文件

子模块cloud-mall-eureka-server配置：application.properties

spring.application.name=eureka-server
server.port=8000
eureka.instance.hostname=localhost
#单节点不需要获取其他节点信息
eureka.client.fetch-registry=false
#不需要把自己注册上去
eureka.client.register-with-eureka=false 
eureka.client.service-url.defaultZone=http://${eureka.instance.hostname}:${server.port}/eureka/

3、启动注解

子模块cloud-mall-eureka-server启动类：EurekaServerApplication

@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {public static void main(String[] args) {SpringApplication.run(EurekaServerApplication.class,args);}
}

二、用户模块开发

1、引入依赖

子模块cloud-mall-user依赖：pom.yml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"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"><parent><artifactId>cloud-mall-practice</artifactId><groupId>com.imooc</groupId><version>1.0-SNAPSHOT</version></parent><modelVersion>4.0.0</modelVersion><artifactId>cloud-mall-user</artifactId><dependencies>
<!--        //对外访问的web依赖--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency>
<!--        //连接mysql的依赖--><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency>
<!--        //mybatis的依赖--><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>2.1.1</version></dependency>
<!--        eureka客户端依赖--><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-eureka-client</artifactId></dependency>
<!--        //redis依赖--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency>
<!--        //session redis的依赖--><dependency><groupId>org.springframework.session</groupId><artifactId>spring-session-data-redis</artifactId></dependency>
<!--        //openfeign服务间调用依赖--><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-openfeign</artifactId></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

三、模块开发

1、常量

2、异常

3、工具类
