在SpringBoot gRPC中集成全局異常處理可以通過以下步驟實現:
io.grpc.ServerInterceptor
接口,并重寫interceptCall
方法以捕獲異常。public class GlobalExceptionHandler implements ServerInterceptor {
@Override
public <ReqT, RespT> ServerCall.Listener<ReqT> interceptCall(ServerCall<ReqT, RespT> serverCall, Metadata metadata, ServerCallHandler<ReqT, RespT> serverCallHandler) {
ServerCall.Listener<ReqT> listener = serverCallHandler.startCall(serverCall, metadata);
return new ForwardingServerCallListener.SimpleForwardingServerCallListener<ReqT>(listener) {
@Override
public void onHalfClose() {
try {
super.onHalfClose();
} catch (Exception e) {
// 處理異常
Status status = Status.INTERNAL.withDescription(e.getMessage());
serverCall.close(status, new Metadata());
}
}
};
}
}
@Configuration
public class GrpcConfig extends GrpcServerConfigurerAdapter {
@Override
public void addServerInterceptors(ServerInterceptorRegistry registry) {
registry.addServerInterceptors(new GlobalExceptionHandler());
}
}
通過以上步驟,就可以在SpringBoot gRPC中實現全局異常處理。當服務中出現異常時,全局異常處理器會捕獲異常并返回自定義的錯誤信息。
