1 鉴权
1.1 在bootstrap.yml 中定义过滤器 dubbo.provider.filter: 过滤器的名字 1.2 resources 目录下创建配置文件 1 resources 创建目录/META-INF/dubbo 2 创建文件名字为org.apache.dubbo.rpc.Filter 的纯文本文件 3 定义过滤器 过滤器名字过滤器路径地址 4服务提供端DubboTokenFilter

}
ResponseDTO 封装类
// loomback 插件
Data
Accessors(chain true)
public class ResponseDTOT implements Serializable {private static final long serialVersionUID 3918877423924837166L;private int code 200;private T body;private String msg;private boolean redirect true;private ListResponseMessage messages;private ListString message new ArrayList();private int errNum;private String errorMsg;private Object errorObject;private boolean success true;public static T ResponseDTO defaultResponse(T t) {return new ResponseDTO().setCode(BizHttpStatus.HTTP_STATUS_200.getStatus()).setBody(t);}
}RedisUtil 封装类stringRedisTemplate bean 自行配置实现
Component
public class RedisUtil {AutowiredQualifier(stringRedisTemplate)private StringRedisTemplate redisTemplate;public void setRedisTemplate(StringRedisTemplate redisTemplate) {this.redisTemplate redisTemplate;}public StringRedisTemplate getRedisTemplate() {return this.redisTemplate;}/*** 获取指定 key 的值** param key* return*/public String get(String key) {return redisTemplate.opsForValue().get(key);}/*** 设置指定 key 的值** param key* param value*/public void set(String key, String value) {redisTemplate.opsForValue().set(key, value);}
}服务业务类提供者 DubboTestServiceImpl
import org.apache.dubbo.config.annotation.DubboService;
import org.lgx.bluegrass.api.common.dto.ResponseDTO;
import org.lgx.bluegrass.api.service.DubboTestService;/*** Description TODO* Date 2023/2/23 15:50* Author lgx* Version 1.0*/
// dubbo 服务暴露标识token 1234 定义token验证标识
DubboService(token 1234)
public class DubboTestServiceImpl implements DubboTestService {Overridepublic ResponseDTO test(String token) {return ResponseDTO.defaultResponse(hello es token);}
}
服务定义DubboThreeService
public interface DubboThreeService {ResponseDTO testOne(String token);
}
5 消费端同服务提供端12,3,相同 定义好过滤器 定义消费端token 填充 DubboTokenFilter
public class DubboTokenFilter implements Filter {private RedisUtil redisUtil;Overridepublic Result invoke(Invoker? invoker, Invocation inv) throws RpcException {if (null redisUtil) {Object obj ApplicationContextUtils.getBean(redisUtil);if (null ! obj){redisUtil (RedisUtil) obj;}}String isNeedToken invoker.getUrl().getParameter(Constants.TOKEN_KEY);// 是否需要进行token 验证if (StringUtils.hasText(isNeedToken)) {// Constants.TOKEN_KEY, 1234 便于跳过duboo 内置的token 验证// 1234 对应服务提供端业务实现类中定义的token DubboService(token 1234)inv.setAttachment(Constants.TOKEN_KEY, 1234);// 设置本次真正需要验证的tokeninv.setAttachment(dubbo_accesstoken, 1234qazwsxedc);}// 远程接口调用return invoker.invoke(inv);}
}6 消费端测试
RestController
public class DubboRpcController {DubboReferenceprivate DubboTestService dubboTestService;RequestMapping(value /dubbo-test, method RequestMethod.GET)public String index(RequestParam(token) String token) {return dubboTestService.test(token).toString();}
}2 日志记录
DubboAccessLogFilter
import org.apache.dubbo.common.logger.Logger;
import org.apache.dubbo.common.logger.LoggerFactory;
import org.apache.dubbo.common.utils.ConfigUtils;
import org.apache.dubbo.rpc.*;
import org.apache.dubbo.rpc.support.AccessLogData;import java.util.Date;/*** Description TODO* Date 2023/3/8 16:48* Author lgx* Version 1.0*/
public class DubboAccessLogFilter implements Filter {private static final Logger logger LoggerFactory.getLogger(DubboAccessLogFilter.class);Overridepublic Result invoke(Invoker? invoker, Invocation inv) throws RpcException {try {// 是否需要对改接口进行日志记录String accessLogKey invoker.getUrl().getParameter(accesslog);if (ConfigUtils.isNotEmpty(accessLogKey)) {// 请求的数据AccessLogData logData this.buildAccessLogData(invoker, inv);// save logsaveLog(logData);}} catch (Throwable var5) {logger.warn(Exception in AccessLogFilter of service( invoker - inv ), var5);}return invoker.invoke(inv);}// 自行实现数据的保存private void saveLog(AccessLogData logData) {}private AccessLogData buildAccessLogData(Invoker? invoker, Invocation inv) {AccessLogData logData AccessLogData.newLogData();logData.setServiceName(invoker.getInterface().getName());logData.setMethodName(inv.getMethodName());logData.setVersion(invoker.getUrl().getParameter(version));logData.setGroup(invoker.getUrl().getParameter(group));logData.setInvocationTime(new Date());logData.setTypes(inv.getParameterTypes());logData.setArguments(inv.getArguments());return logData;}
}
服务业务提供端
// accesslog 日志记录标识
DubboService(accesslog 123)
public class DubboTestServiceTwoImpl implements DubboTestTwoService {Overridepublic ResponseDTO sayHello() {MapString,Object result new HashMap(12);result.put(data,Hello !);result.put(success,true);result.put(code,200);return ResponseDTO.defaultResponse(result);}
}3 数据统一封装
AppendedFilter:
import org.apache.dubbo.rpc.*;
import org.lgx.bluegrass.api.common.dto.ResponseDTO;/*** Description TODO* Date 2023/3/7 11:00* Author lgx* Version 1.0*/
public class AppendedFilter implements Filter {Overridepublic Result invoke(Invoker? invoker, Invocation invocation) throws RpcException {Result result invoker.invoke(invocation);Result appResponse ((AsyncRpcResult) result).getAppResponse();Object data appResponse.getValue();if (data instanceof ResponseDTO) {return result;}// 统一进行ResponseDTO 格式数据封装返回appResponse.setValue(ResponseDTO.defaultResponse(data));return result;}
}
