创建子服务：ly-item

在pom中将包类型改为pom <?xmlversion="1.0"encoding="UTF-8"?> <projectxmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0http://maven.apache.org/xsd/maven-4.0.0.xsd"> <parent> <artifactId>leyou</artifactId> <groupId>com.leyou.parent</groupId> <version>1.0.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion>

<groupId>com.leyou.service</groupId> <artifactId>ly-Item</artifactId> <packaging>pom</packaging> </project>

再在ly-item下创建子工程

ly-item-interface

ly-item-service

ly-item实体类基本上不需要什么依赖 ly-item-service中需要依赖，配置pom文件 <?xmlversion="1.0"encoding="UTF-8"?> <projectxmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0http://maven.apache.org/xsd/maven-4.0.0.xsd"> <parent> <artifactId>ly-item</artifactId> <groupId>com.leyou.service</groupId> <version>1.0.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion>

<groupId>com.leyou.service</groupId> <artifactId>ly-item-service</artifactId>

<dependencies> <!--web启动器--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!--Eureka客户端--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> </dependency> <!--通用Mapper启动器--> <dependency> <groupId>tk.mybatis</groupId> <artifactId>mapper-spring-boot-starter</artifactId> </dependency> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper-spring-boot-starter</artifactId> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <dependency> <groupId>com.leyou.service</groupId> <artifactId>ly-item-interface</artifactId> <version>1.0.0-SNAPSHOT</version> </dependency> </dependencies> </project>

新建启动类

packagecom.leyou;

importorg.springframework.boot.SpringApplication; importorg.springframework.boot.autoconfigure.SpringBootApplication; importorg.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication @EnableDiscoveryClient publicclass LyItemApplication{ publicstaticvoid main(String[]args){ SpringApplication.run(LyItemApplication.class,args); } }

新建application.yml server: port:8081 spring: application: name:item-service datasource:#_数据库驱动可自动推断，不用配置 url:jdbc:mysql://localhost:3306/yun6 username:root password:123 eureka: client: service-url: defaultZone:http://127.0.0.1:10086/eureka instance:#_确定拿到的一定是__ip prefer-ip-address:true ip-address:127.0.0.1

修改ly-gateway配置文件

至此，微服务搭建完毕 依次启动LyRegistry,LyItemApplication，LyGateway进行测试 在浏览器中打开http://127.0.0.1:10086/ 可以在gateway的配置文件中修改拉取的时间，默认30s 关键字fetch

如果不想eruka注册自己，可以在ly-registry中进行配置
