标签:方案   添加   art   实体   run   template   register   obj   spi   

1

.创建maven工程

2.添加web和eureka依赖

技术图片

在pom.xml添加依赖如下,目的是@DATA用到

<!-- lombok代码模板解决方案,没有使用lombok的可以把这个依赖删除 -->
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.16.10</version>
</dependency>

3.编写服务端口和注册配置application.yml

server:
port: 8761
spring:
application:
name: eureka-server1
eureka:
instance:
hostname: server1
client:
registerWithEureka: false
fetchRegistry : false
serviceUrl:
defaultZone: http://server2:8762/eureka/
4.编写启动类EurekaServerApplication.java,添加@EnableEurekaServer
@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {

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

}
4-2启动

5.用统样方法配置端口8762的服务注册,和8761互相注册调用

6.编写消费者consumer,

用同样方法创建springboot的项目,

配置application.yml如下

server:
port: 8084

spring:
application:
name: eureka-consumer

eureka:
client:
serviceUrl:
defaultZone: http://localhost:8761/eureka,http://localhost:8762/eureka
编写启动类如下:
@SpringBootApplication
@EnableEurekaClient
public class MicreoserviceDicoveryEurekaConsumerApplication {

public static void main(String[] args) {
SpringApplication.run(MicreoserviceDicoveryEurekaConsumerApplication.class, args);
}

}
编写控制层类如下
@Controller
@Configuration
public class ConsumerController {
@Bean
@LoadBalanced
public RestTemplate getRestTemplate(){
return new RestTemplate();
}
//当访问localhost:8084/router时跳转到http://eureka-provider/search/1地址
    @GetMapping(value = "/router")
@ResponseBody
public String router() {
RestTemplate temp = getRestTemplate();
return temp.getForObject("http://eureka-provider/search/1", String.class);
}
}

7.用同样方法创建springboot的供应商类
application.yml如下
spring:
application:
name: eureka-provider

eureka:
client:
serviceUrl:
defaultZone: http://localhost:8761/eureka,http://localhost:8762/eureka
server:
port: 8082
启动类如下:
@SpringBootApplication
@EnableEurekaClient
public class MicreaoserviceDicoveryEurekaProvider02Application {

public static void main (String[]args){
SpringApplication.run(MicreaoserviceDicoveryEurekaProvider02Application.class, args);
}

}
控制层类如下
@RestController
public class ProviderController {

@RequestMapping(value = "/search/{id}", method = RequestMethod.GET,produces = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public Person searchPerson(@PathVariable Integer id, HttpServletRequest request) {
Person person = new Person();
person.setId(id);
person.setName("Spirit");
person.setMessage(request.getRequestURL().toString());
return person;

}
}

实体类如下


@Data
public class Person {

private Integer id; //主键ID
private String name; //姓名
private String message; //信息

public Integer getId() {
return id;
}

public void setId(Integer id) {
this.id = id;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getMessage() {
return message;
}

public void setMessage(String message) {
this.message = message;
}
}

8.先启动8761和8762端口,然后访问http://localhost:8762/http://localhost:8761/可以看到注册的端口

9.再启动8082和8084端口,然后访问localhost:8084/router会跳转到http://eureka-provider/search/1页面
