4.api相关配置编写
ExampleService接口类编写
1 package com.goku.demo.api.service; 2 3 /** 4 * Created by nbfujx on 2017-11-23. 5 */ 6 public interface ExampleService { 7 String echo(String str); 8 }
5.provider相关配置编写
application.properties编写
## 避免和 consumer 工程端口冲突 server.port=8081 spring.dubbo.application.name=provider spring.dubbo.registry.address=zookeeper://localhost:2181 spring.dubbo.protocol.name=dubbo spring.dubbo.protocol.port=20880 ## 本机的IP地址 spring.dubbo.protocol.host=127.0.0.1 spring.dubbo.scan=com.goku.demo ## 设置Module spring.dubbo.module.default=false
ExampleServiceImpl接口实现类编写
package com.goku.demo.service.impl;
import com.goku.demo.api.service.ExampleService;
import com.alibaba.dubbo.config.annotation.Service;
/**
* Created by nbfujx on 2017-11-23.
*/
@Service(version = "1.0.0")
public class ExampleServiceImpl implements ExampleService {
@Override
public String echo(String str) {
return "hello"+ str;
}
}
6.consumer相关配置编写
application.properties编写
spring.dubbo.application.name=consumer spring.dubbo.registry.address=zookeeper://localhost:2181 spring.dubbo.scan=com.goku.demo spring.dubbo.module.default=false
ExampleController控制器编写
1 package com.goku.demo.controller; 2 3 import com.alibaba.dubbo.config.annotation.Reference; 4 import com.goku.demo.api.service.ExampleService; 5 import org.springframework.web.bind.annotation.PathVariable; 6 import org.springframework.web.bind.annotation.RequestMapping; 7 import org.springframework.web.bind.annotation.RestController; 8 9 /** 10 * Created by nbfujx on 2017-11-20. 11 */ 12 @RestController 13 public class ExampleController { 14 15 @Reference(version = "1.0.0") 16 public ExampleService exampleService; 17 18 @RequestMapping("/") 19 public String helloWorld() 20 { 21 return "helloWorld"; 22 } 23 24 @RequestMapping("/{str}") 25 public String echo(@PathVariable String str) 26 { 27 return exampleService.echo(str); 28 } 29 }
7.在页面上运行
8.降级服务
mock的配置可以在出现非业务异常(比如超时，网络异常等)时执行。mock的配置支持两种，一种为boolean值，默认的为false。如果配置为true，则缺省使用mock类名，即类名+Mock后缀；另外一种则是配置"return null"，可以很简单的忽略掉异常。
ExampleServiceMock缺省类编写
1 package com.goku.demo.api.service; 2 3 import org.springframework.stereotype.Service; 4 5 /** 6 * Created by nbfujx on 2017-11-27. 7 */ 8 @Service 9 public class ExampleServiceMock implements ExampleService { 10 @Override 11 public String echo(String str) { 12 return "hello"+ str+"this is error!"; 13 } 14 }
ExampleController控制器修改
1 package com.goku.demo.controller; 2 3 import com.alibaba.dubbo.config.annotation.Reference; 4 import com.goku.demo.api.service.ExampleService; 5 import com.goku.demo.api.service.ExampleServiceMock; 6 import org.springframework.beans.factory.annotation.Autowired; 7 import org.springframework.web.bind.annotation.PathVariable; 8 import org.springframework.web.bind.annotation.RequestMapping; 9 import org.springframework.web.bind.annotation.RestController; 10 11 /** 12 * Created by nbfujx on 2017-11-20. 13 */ 14 @RestController 15 public class ExampleController { 16 17 @Reference(version = "1.0.0",check=false,mock="com.goku.demo.api.service.ExampleServiceMock") 18 @Autowired 19 public ExampleService exampleService; 20 21 @RequestMapping("/") 22 public String helloWorld() 23 { 24 return "helloWorld"; 25 } 26 27 @RequestMapping("/{str}") 28 public String echo(@PathVariable String str) 29 { 30 return exampleService.echo(str); 31 } 32 }
