2、搭建框架
2.1、父工程
创建Maven工程pinyougou-parent （POM） ，groupId 为com.pinyougou ,artifactId 为pinyougou-parent 。

2.3、服务注册中心模块
创建服务注册中心模块-pinyougou-eurekaserver
配置注册中心,端口号设置为8761
server: port: 8761 eureka: instance: hostname: localhost # eureka实例的主机名 client: register-with-eureka: false #不把自己注册到eureka上 fetch-registry: false #不从eureka上来获取服务的注册信息 service-url: defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/ #服务的注册地址
添加启动类,开启Eureka Server服务
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
@EnableEurekaServer //开启Eureka Server
public class EurekaServerApplication {
public static void main(String[] args){
SpringApplication.run(EurekaServerApplication.class,args);
}
}
测试:启动Eureka Server服务,浏览器输入http://localhost:8761/,
能访问springEureka说明服务注册中心配置成功.
2.4、通用实体类模块
创建通用实体类模块-pinyougou-pojo
Pojo:数据库实体类
Entity:统一返回数据实体类
Pojogroup:封装的实体类数据
2.5、通用数据访问模块
创建通用数据访问模块pinyougou-dao .添加依赖pinyougou-pojo
新建包com.pinyougou.mapper,写需要的mapper接口,注意:需要在加注释@Mapper
在resource下,写mapper映射文件
2.6、通用工具类模块
创建通用工具类模块pinyougou-common
2.7、商家商品服务接口模块
创建模块pinyougou-sellergoods-interface,添加依赖pinyougou-pojo
新建包com.pinyougou.sellergoods.service,写service层接口
2.8、服务接口提供模块
创建pinyougou-api(pom)
说明:该模块提供各模块所需提供的接口,为api父工程,各模块需要提供接口服务时,在该父工程下新建各自的子模块.
本项目实现流程:该模块提供的接口,在对应service模块编写逻辑,调用方调用服务的时候,继承api提供的接口,使用@FeignClient(‘service模块的名称’)注解调用服务.
2.9、商品服务api
创建pinyougou-sellergoods-api模块,依赖pinyougou-pojo
创建包com.pinyougou.pojo.TbBrand,编写一个测试类:
@RequestMapping("/brand")
public interface BrandApiService {
@RequestMapping("/findAll")
public List<TbBrand> findAll();
}
2.10、商家商品服务模块
创建pinyougou-sellergoods-service,
添加依赖pinyougou-sellergoods-interface,pinyougou-dao,pinyougou-sellergoods-api
配置文件:
server: port: 9001 eureka: client: service-url: defaultZone: http://localhost:8761/eureka/ spring: application: name: sellergoods datasource: name: pinyougoudb #?useUnicode=true&characterEncoding=utf8 url: jdbc:mysql://localhost:3306/pinyougoudb?useUnicode=true&characterEncoding=utf8&serverTimezone=UTC username: root password: root # 使用druid数据源 type: com.alibaba.druid.pool.DruidDataSource driver-class-name: com.mysql.cj.jdbc.Driver # 数据源其他配置 initialSize: 5 minIdle: 5 maxActive: 20 maxWait: 60000 timeBetweenEvictionRunsMillis: 60000 minEvictableIdleTimeMillis: 300000 validationQuery: SELECT 1 FROM DUAL testWhileIdle: true testOnBorrow: false testOnReturn: false poolPreparedStatements: true # 配置监控统计拦截的filters，去掉后监控界面sql无法统计，‘wall‘用于防火墙 filters: stat,wall,log4j maxPoolPreparedStatementPerConnectionSize: 20 useGlobalDataSourceStat: true connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500 mybatis: # 指定全局配置文件位置 #config-location: classpath:mybatis/mybatis-config.xml mapper-locations: classpath*:/mapper/*Mapper.xml #实体扫描，多个package用逗号或者分号分隔 type-aliases-package: com.pinyougou.pojo configuration: #配置返回数据库(column下划线命名&&返回java实体是驼峰命名)，自动匹配无需as（没开启这个，SQL需要写as： select user_id as userId） map-underscore-to-camel-case: true #配置JdbcTypeForNull, oracle数据库必须配置 jdbc-type-for-null: ‘null‘
编写启动类,添加扫描mapper类的注解,将服务注册到注册中心
@MapperScan(value = "com.pinyougou.mapper") @SpringBootApplication @EnableEurekaClient public class SellerGoodsServiceApplication { public static void main(String[] args) { SpringApplication.run(SellerGoodsServiceApplication.class, args); } }
创建包com.pinyougou.sellergoods.service.impl,作用:实现interface模块,编写数据访问层业务逻辑.注意:该类上要加@Service注解.
创建包com.pinyougou.sellergoods.api.service.impl,作用:实现服务提供者api接口,编写暴露接口的业务逻辑,注意:该类上要添加@RestController注解.
2.11、运营商管理后台
创建包pinyougou-manager-web,依赖pinyougou-sellergoods-api
在resources下创建配置文件:
server: port: 9101 eureka: client: service-url: defaultZone: http://localhost:8761/eureka/ spring: freemarker: suffix: .html templateLoaderPath: classpath:/templates/ cache: false #禁用模板缓存,正式环境取消 application: name: managerweb main: allow-bean-definition-overriding: true
创建包com.pinyougou.manager.feign,用于服务的调用
@FeignClient("sellergoods") //写service层的名称
public interface BrandFeign extends BrandApiService {
}
此时,就可以使用BrandFeign调用BrandApiService的接口
创建包com.pinyougou.manager.controller,进行测试
@RestController @RequestMapping("/brands") public class BrandController { @Autowired private BrandFeign brandFeign; @RequestMapping("/findAll") public List<TbBrand> findAll(){ List<TbBrand> lists=null; lists=brandFeign.findAll(); return lists; } }
启动服务:
启动pinyougou-eurekaserver
启动pinyougou-sellergoods-service
启动pinyougou-manager-web
在浏览器输入:http://localhost:9101/brands/findAll,如果能获取到数据库数据,说明服务调用成功.
此时,浏览器中输入http://localhost:8761/,能看到刚启动的两个服务已经注册到Eureka注册中心了.
