网站建设公司 枫子伽叩,罗伯特清崎说的网络营销是什么,怎么在百度上创建自己的网页,一般通过饼干目录
1.启动zookeeper❤️❤️❤️
2.创建8004模块 ❤️❤️❤️ 3.临时节点还是永久节点❤️❤️❤️
4.创建zk80消费模块❤️❤️❤️ 1.启动zookeeper❤️❤️❤️
进入自己zookeeper的bin目录下 分别使用命令#xff1a;

1.启动zookeeper❤️❤️❤️
2.创建8004模块 ❤️❤️❤️ 3.临时节点还是永久节点❤️❤️❤️
4.创建zk80消费模块❤️❤️❤️ 1.启动zookeeper❤️❤️❤️
进入自己zookeeper的bin目录下 分别使用命令
./zkServer.sh start 和 ./zkCli.sh -server 主机名 2.创建8004模块 ❤️❤️❤️
1.建模块 在父工程下创建模块 注意jdk版本和maven版本 2.添加pom 1.springboot依赖 2.mybatis依赖 3.druid依赖 4.mysql依赖 5.zookeeper依赖 dependenciesdependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-web/artifactId/dependencydependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-actuator/artifactId/dependencydependencygroupIdorg.mybatis.spring.boot/groupIdartifactIdmybatis-spring-boot-starter/artifactId/dependencydependencygroupIdcom.alibaba/groupIdartifactIddruid-spring-boot-starter/artifactIdversion1.2.16/version/dependency!--mysql-connector-java--dependencygroupIdmysql/groupIdartifactIdmysql-connector-java/artifactId/dependency!--jdbc--dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-jdbc/artifactId/dependencydependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-devtools/artifactIdscoperuntime/scopeoptionaltrue/optional/dependencydependencygroupIdorg.projectlombok/groupIdartifactIdlombok/artifactIdoptionaltrue/optional/dependencydependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-test/artifactIdscopetest/scope/dependency!--引入自己的api通用包--dependencygroupIdorg.example/groupIdartifactIdcloud-api-commons/artifactIdversion${project.version}/version/dependency!--springboot整合zookeeper客户端--dependencygroupIdorg.springframework.cloud/groupIdartifactIdspring-cloud-starter-zookeeper-discovery/artifactId/dependency/dependencies
3.添加yml 1.服务端口 2.服务名称 3.数据库连接池 4.zookeeper连接地址 5.mybatis配置 server:port: 8004spring:application:#服务名称name: cloud-provider-paymentdatasource:#druid连接池type: com.alibaba.druid.pool.DruidDataSourcedriver-class-name: com.mysql.cj.jdbc.Driverurl: jdbc:mysql://localhost:3306/springcloudusername: rootpassword: 123456#zookeeper服务注册中心cloud:zookeeper:connect-string: 192.168.20.129:2181,192.168.20.130:2181,192.168.20.131:2181mybatis:mapper-locations: classpath:mapper/*.xmltype-aliases-package: com.xz.springcloud.entity
4.添加主启动类 EnableDiscoveryClient:将服务注册到服务注册中心zookeeper SpringBootApplication
EnableDiscoveryClient//作为服务中心
public class PaymentMain8004 {public static void main(String[] args) {SpringApplication.run(PaymentMain8004.class);}
}
5.编写业务类
RestController
public class PaymentController {Autowiredprivate PaymentService paymentService;Value(${server.port})private String serverPort;GetMapping(/payment/getById/{id})public CommonResult getById(PathVariable(id) Integer id){Payment payment paymentService.getPaymentById(id);if (payment!null){return new CommonResult(200,查询成功,serverPort:serverPort,payment);}else {return new CommonResult(404,查询无果serverPort:serverPort,null);}}RequestMapping(/payment/zk)public String paymentZk(){return springCloud with zookeeper:serverPort\t UUID.randomUUID().toString();}
}6.测试
1.启动主启动类,刷新浏览器 2.访问zookeeper 说明zookeeper配置成功 3.临时节点还是永久节点❤️❤️❤️
当关闭8004服务时在查询zookeeper发现节点剔除 所以zookeeper存储的是临时节点当服务消失时会马上剔除
4.创建zk80消费模块❤️❤️❤️
1.建模块 在父工程下创建模块 注意jdk版本和maven版本 2.写pom 1.springboot依赖 2.通用依赖 3.zookeeper依赖 dependenciesdependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-web/artifactId/dependencydependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-actuator/artifactId/dependencydependencygroupIdorg.projectlombok/groupIdartifactIdlombok/artifactIdoptionaltrue/optional/dependencydependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-test/artifactIdscopetest/scope/dependencydependencygroupIdorg.example/groupIdartifactIdcloud-api-commons/artifactIdversion${project.version}/version/dependency!--spring boot整合zookeeper--dependencygroupIdorg.springframework.cloud/groupIdartifactIdspring-cloud-starter-zookeeper-discovery/artifactId/dependency/dependencies
3.改yml 1.服务端口 2.服务名 3.zookeeper连接ip我这里使用集群 server:port: 80spring:application:name: cloud-consumer-ordercloud:zookeeper:connect-string: 192.168.20.129:2181,192.168.20.130:2181,192.168.20.131:21814.主启动类 EnableDiscoveryClient添加上 SpringBootApplication
EnableDiscoveryClient
public class OrderZkMain80 {public static void main(String[] args) {SpringApplication.run(OrderZkMain80.class);}
}
5.业务代码
1.先将Rest Template注入到spring中
注意因为访问的是服务名而不是具体的ip所以加上LoadBalance注解
Configuration
public class ApplicationConfig {BeanLoadBalancedpublic RestTemplate getRestTemplate(){return new RestTemplate();}
}
2.controller 1.声明常量表示zookeeper中8004的服务名 2.注入RestTemplate 3.调用restTemplate访问 RestController
public class OrderController {public static final String INVOKE_URL http://cloud-provider-payment;Autowiredprivate RestTemplate restTemplate;GetMapping(/payment/getById/{id})public CommonResultPayment getPayment(PathVariable(id) Integer id){return restTemplate.getForObject(INVOKE_URL/payment/getById/id,CommonResult.class);}GetMapping(/payment/zk)public String getDiscovery(){return restTemplate.getForObject(INVOKE_URL/payment/zk,String.class);}
}
6.测试
1.使用80访问刷新浏览器依然成功 2.查看zookeeper节点 节点创建成功
