dubbox框架的搭建小伙伴们知道该怎么配置吗?上会我们聊完了它的原理，这次就一起来看看它该如何搭建吧。
一、定义服务接口及传输对象DTO
项目结构如下:
具体实现代码：
User.java
package yjmyzz.dubbo.demo.api;
import org.codehaus.jackson.annotate.JsonProperty;
import javax.validation.constraints.Min;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import java.io.Serializable;
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class User implements Serializable
{
@NotNull
@Min(1 L)
private Long id;
@JsonProperty("username")
@XmlElement(name = "username")
@NotNull
@Size(min = 6, max = 50)
private String name;
public User()
{}
public User(Long id, String name)
{
this.id = id;
this.name = name;
}
public Long getId()
{
return id;
}
public void setId(Long id)
{
this.id = id;
}
public String getName()
{
return name;
}
public void setName(String name)
{
this.name = name;
}
@Override
public String toString()
{
return "User (" +
"id=" + id +
", name='" + name + '\'' +
')';
}
}UserService.java
package yjmyzz.dubbo.demo.api;
public interface UserService
{
User getUser(Long id);
}UserRestService.java
package yjmyzz.dubbo.demo.api;
import javax.validation.constraints.Min;
public interface UserRestService
{
User getUser(@Min(value = 1 L, message = "User ID must be greater than 1") Long id);
}pom.xml
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.cnblogs.yjmyzz</groupId> <artifactId>dubbo-hello-api</artifactId> <version>0.1</version> <dependencies> <dependency> <groupId>com.alibaba</groupId> <artifactId>dubbo</artifactId> <version>2.8.4</version> </dependency> <dependency> <groupId>javax.validation</groupId> <artifactId>validation-api</artifactId> <version>1.0.0.GA</version> </dependency> <dependency> <groupId>javax.annotation</groupId> <artifactId>javax.annotation-api</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.12</version> </dependency> </dependencies> </project>
二、定义服务生产者
UserServiceImpl.java
package yjmyzz.dubbo.demo.provider;
import yjmyzz.dubbo.demo.api.User;
import yjmyzz.dubbo.demo.api.UserService;
public class UserServiceImpl implements UserService
{
public User getUser(Long id)
{
return new User(id, "username" + id);
}
}UserRestServiceImpl.java
package yjmyzz.dubbo.demo.provider;
import com.alibaba.dubbo.rpc.RpcContext;
import com.alibaba.dubbo.rpc.protocol.rest.support.ContentType;
import yjmyzz.dubbo.demo.api.User;
import yjmyzz.dubbo.demo.api.UserRestService;
import yjmyzz.dubbo.demo.api.UserService;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.ws.rs.*;
import javax.ws.rs.core.MediaType;
@Path("users")
@Consumes(
{
MediaType.APPLICATION_JSON
, MediaType.TEXT_XML
})
@Produces(
{
ContentType.APPLICATION_JSON_UTF_8
, ContentType.TEXT_XML_UTF_8
})
public class UserRestServiceImpl implements UserRestService
{
private UserService userService;
public void setUserService(UserService userService)
{
this.userService = userService;
}
@GET
@Path("{id : \\d+}")
public User getUser(@PathParam("id") Long id)
{
if (RpcContext.getContext()
.getRequest(HttpServletRequest.class) != null)
{
System.out.println("Client IP address from RpcContext: " + RpcContext.getContext()
.getRequest(HttpServletRequest.class)
.getRemoteAddr());
}
if (RpcContext.getContext()
.getResponse(HttpServletResponse.class) != null)
{
System.out.println("Response object from RpcContext: " + RpcContext.getContext()
.getResponse(HttpServletResponse.class));
}
return userService.getUser(id);
}
}DemoProvider.java
package yjmyzz.dubbo.demo.provider;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import java.io.IOException;
public class DemoProvider
{
public static void main(String[] args) throws IOException
{
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath*:META-INF/spring/*.xml");
context.start();
System.out.println("服务已经启动...");
System.in.read();
}
}配置文件：resources\META-INF\spring\dubbo-demo-provider.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd"> <dubbo:application name="demo-provider" owner="programmer" organization="dubbox"/> <dubbo:registry address="zookeeper://127.0.0.1:2181"/> <dubbo:protocol name="dubbo" serialization="kryo" optimizer="yjmyzz.dubbo.demo.api.SerializationOptimizerImpl"/> <!-- use tomcat server --> <dubbo:protocol name="rest" port="8888" threads="500" contextpath="services" server="tomcat" accepts="500" extension="com.alibaba.dubbo.rpc.protocol.rest.support.LoggingFilter"/> <dubbo:service interface="yjmyzz.dubbo.demo.api.UserService" ref="userService" protocol="dubbo" /> <dubbo:service interface="yjmyzz.dubbo.demo.api.UserRestService" ref="userRestService" protocol="rest" validation="true"/> <bean id="userService" class="yjmyzz.dubbo.demo.provider.UserServiceImpl"/> <bean id="userRestService" class="yjmyzz.dubbo.demo.provider.UserRestServiceImpl"> <property name="userService" ref="userService"/> </bean> </beans>

测试时，运行DemoProvider中的main方法即可启动服务，所有服务注册在ZooKeeper，层次结构类似下面这样：
/dubbo / dubbo / yjmyzz.dubbo.demo.api.UserRestService / dubbo / yjmyzz.dubbo.demo.api.UserRestService / providers / dubbo / yjmyzz.dubbo.demo.api.UserRestService / configurators / dubbo / yjmyzz.dubbo.demo.api.UserService / dubbo / yjmyzz.dubbo.demo.api.UserService / providers / dubbo / yjmyzz.dubbo.demo.api.UserService / configurators
三、定义服务消费方
DemoConsumer.java
package yjmyzz.dubbo.demo.consumer;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import yjmyzz.dubbo.demo.api.UserService;
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.WebTarget;
import javax.ws.rs.core.Response;
public class DemoConsumer
{
public static void main(String[] args)
{
final String port = "8888";
//测试Rest服务
getUser("http://localhost:" + port + "/services/users/1.json");
getUser("http://localhost:" + port + "/services/users/1.xml");
//测试常规服务
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath*:META-INF/spring/*.xml");
context.start();
UserService userService = context.getBean(UserService.class);
System.out.println(userService.getUser(1 L));
}
private static void getUser(String url)
{
System.out.println("Getting user via " + url);
Client client = ClientBuilder.newClient();
WebTarget target = client.target(url);
Response response = target.request()
.get();
try
{
if (response.getStatus() != 200)
{
throw new RuntimeException("Failed with HTTP error code : " + response.getStatus());
}
System.out.println("Successfully got result: " + response.readEntity(String.class));
}
finally
{
response.close();
client.close();
}
}
}配置文件：resources\META-INF\spring\dubbo-hello-consumer.xml

全部配置完整，则搭建成功了。
以上就是本文的全部内容了，相比于dubbo，dubbox功能显得更加丰富。还想了解更多java项目中常见问题及答案就请持续关注本网站吧。
