Example 1 with Connection

use of com.tencent.polaris.plugins.connector.grpc.Connection in project polaris-java by polarismesh.

the class PolarisConfigFileConnector method getConfigFile.

@Override
public ConfigFileResponse getConfigFile(ConfigFile configFile) {
    Connection connection = null;
    try {
        connection = connectionManager.getConnection(OP_KEY_GET_CONFIG_FILE, ClusterType.SERVICE_DISCOVER_CLUSTER);

        PolarisConfigGRPCGrpc.PolarisConfigGRPCBlockingStub stub = PolarisConfigGRPCGrpc.newBlockingStub(connection.getChannel());
        // 附加通用 header
        GrpcUtil.attachRequestHeader(stub, GrpcUtil.nextInstanceRegisterReqId());
        // 执行调用
        ConfigFileProto.ConfigFileResponse response = stub.getConfigFile(transfer2DTO(configFile));

    } catch (Throwable t) {
        // 网络访问异常
