在SpringBoot gRPC中集成全局异常处理可以通过以下步骤实现:
io.grpc.ServerInterceptor
接口,并重写interceptCall
方法以捕获异常。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) {
// 处理异常
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());
}
}
通过以上步骤,就可以在SpringBoot gRPC中实现全局异常处理。当服务中出现异常时,全局异常处理器会捕获异常并返回自定义的错误信息。
