注册中心的配置：
需要的依赖的配置
<parent>
<groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.4.RELEASE</version> <relativePath/> <!-- lookup parent from repository --></parent><properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version></properties><dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <!-- SpringCloud eureka server--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka-server</artifactId> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency></dependencies><dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Dalston.SR1</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies></dependencyManagement>
2、注册中心配置文件application.properties的配置
#配置注册中心我的端口号
server.port=5001
#配置服务的名称
spring.application.name=spring-cloud-register
#服务所在的机器的名称
eureka.instance.hostname=com.lcg.test0
#配置eureka不注册自己
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
#配置注册中心的地址
eureka.client.serviceUrl.defaultZone=http\://${eureka.instance.hostname}\:${server.port}/eureka,http\://com.lcg.test1\:4001/eureka
3、配置中心启动类
package com.lcg;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@SpringBootApplication
@EnableEurekaServer
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run ( DemoApplication.class, args );
}
}
发布接口的服务端的配置
依赖配置：
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.4.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Dalston.SR1</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
2、发布接口的服务端的application.properties配置
#配置服务端的端口
server.port=8090
#服务的名称
spring.application.name=cloud-server-provider
#配置服务的注册中心
eureka.client.service-url.defaultZone==http\://com.lcg.test0\:5001/eureka,http\://com.lcg.test1\:4001/eureka
3、服务端启动类的配置
package com.lcg;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
@SpringBootApplication
@EnableEurekaClient
public class CloudServerProviderApplication {
public static void main(String[] args) {
SpringApplication.run ( CloudServerProviderApplication.class, args );
}
}
4、服务接口的测试
package com.lcg.server;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.client.discovery.DiscoveryClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.servlet.http.HttpServletRequest;
@RestController
public class TestServerProviderController {
@Autowired
private DiscoveryClient discoveryClient;
@RequestMapping("/test")
public String test1(HttpServletRequest request){
System.out.println ("=========ppp===========>"+request.getParameter ( "str" ));
return "server-provider-ok";
}
}
客户端的配置
客户端依赖：
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.4.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-feign</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Dalston.SR1</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
2、客户端application.properties配置文件
server.port=8080
spring.application.name=cloud-server-client
eureka.client.service-url.defaultZone==http\://com.lcg.test0\:5001/eureka,http\://com.lcg.test1\:4001/eureka
3、客户端启动类
package com.lcg;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.feign.EnableFeignClients;
@SpringBootApplication
@EnableEurekaClient
@EnableFeignClients
public class CloudServerClientApplication {
public static void main(String[] args) {
SpringApplication.run ( CloudServerClientApplication.class, args );
}
}
4、测试类
package com.lcg.client;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.sql.SQLOutput;
@RestController
public class TestClientController {
@Autowired
private TestClient testClient;
@RequestMapping("/testClient")
public String test(){
String str= testClient.test000 ( "客户端的请求信息" );
System.out.println ("----------服务端返回--------message------"+str);
return "ok";
}
}
接口配置类
package com.lcg.client;
import org.springframework.cloud.netflix.feign.FeignClient;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
//服务的名称
@FeignClient("cloud-server-provider")
public interface TestClient {
/**
* @RequestParam 配置请求参数的注解
* @param str
* @return
*/
@RequestMapping("/test")
public String test000(@RequestParam("str") String str);
