我试图实现一个 Axis2 服务，它接收用户请求并将它们作为事件发布到 CEP，使用 carbon databridge thrift（通过 'org.wso2.carbon.databridge.agent.thrift.DataPublisher'）

我遵循了 wso2cep-3.1.0/samples/producers/activity-monitor 中提供的代码示例

请看下面的代码片段

public class GatewayServiceSkeleton{

        private static Logger logger = Logger.getLogger(GatewayServiceSkeleton.class);


        public RequestResponse request(Request request)throws AgentException,
                    MalformedStreamDefinitionException,StreamDefinitionException,
                    DifferentStreamDefinitionAlreadyDefinedException,
                    MalformedURLException,AuthenticationException,DataBridgeException,
                    NoStreamDefinitionExistException,TransportException, SocketException,
                    org.wso2.carbon.databridge.commons.exception.AuthenticationException
            {

               final String GATEWAY_SERVICE_STREAM = "gateway.cep";
               final String VERSION = "1.0.0";
               final String PROTOCOL = "tcp://";
               final String CEPHOST = "cep.gubnoi.com";
               final String CEPPORT = "7611";
               final String CEPUSERNAME = "admin";
               final String CEPPASSWORD = "admin";

               Object[] metadata = { request.getDeviceID(), request.getViewID()};
               Object[] correlationdata = { request.getSessionID()};
               Object[] payloaddata = {request.getBucket()};


               KeyStoreUtil.setTrustStoreParams();

               KeyStoreUtil.setKeyStoreParams(); 


               DataPublisher dataPublisher = new DataPublisher(PROTOCOL + CEPHOST + ":" + CEPPORT, CEPUSERNAME, CEPPASSWORD);

                 //create event 
               Event event = new Event (GATEWAY_SERVICE_STREAM + ":" + VERSION, System.currentTimeMillis(), metadata, correlationdata, payloaddata);

                 //Publish event for a valid stream

               dataPublisher.publish(event);
                 //stop 
               dataPublisher.stop();


                RequestResponse response = new RequestResponse();
                response.setSessionID(request.getSessionID());
                response.setDeviceID(request.getDeviceID());
                response.setViewID(request.getViewID());
                response.setBucket(request.getBucket());
                return response; 

            }

还有一个实用程序类将密钥存储参数设置如下

public class KeyStoreUtil {

    static  File filePath = new File("../../../repository/resources/security");

    public static void setTrustStoreParams() {
        String trustStore = filePath.getAbsolutePath();
        System.setProperty("javax.net.ssl.trustStore", trustStore + "/client-truststore.jks");
        System.setProperty("javax.net.ssl.trustStorePassword", "wso2carbon");

    }

    public static void setKeyStoreParams() {
        String keyStore = filePath.getAbsolutePath();
        System.setProperty("Security.KeyStore.Location", keyStore + "/wso2carbon.jks");
        System.setProperty("Security.KeyStore.Password", "wso2carbon");

    }
}

我将服务上传到 wso2as-5.2.1，并使用 SOAPUI 调用服务

请求返回错误消息“无法为 TCP 借用客户端”

我调试，发现问题可能出在“KeyStoreUtil”类上，

其中'filePath'以某种方式重新调整了'null'，

static  File filePath = new File("../../../repository/resources/security");

并导致这条线上的失败

DataPublisher dataPublisher = new DataPublisher(PROTOCOL + CEPHOST + ":" + CEPPORT, CEPUSERNAME, CEPPASSWORD);

我想如果我使用“CARBON_HOME”的值来确定密钥库的位置可能是一个更好的主意

所以我的问题是：

我怎样才能在 Java 代码中获得“CARBON_HOME”的值？

那说。如果您想得更多：该服务将被调用无数次；而“setTrustStoreParams”和“setKeyStoreParams”只需要在服务器/服务启动时执行一次。

那么，有没有更好的方法从服务代码中删除“setTrustStoreParams”和“setKeyStoreParams”，或者作为可配置项实现？

请指教

谢谢

您应该使用如下属性carbon.home来检索 WSO2 产品的主目录。

System.getProperty("carbon.home");
