写了个列表查询接口，
provider端实现：
` public void list(SearchUserRequest request,
StreamObserver<UserResponse> responseObserver) {
users.forEach(c -> {
UserResponse ur =
UserResponse.newBuilder().setId(c.getId()).setName(c.getName()).build();
responseObserver.onNext(ur);
});
responseObserver.onCompleted();
}`
consumer端调用：
`SearchUserRequest request = SearchUserRequest.newBuilder().build();
Iterator<UserResponse> responseIterator = userService.list(request);
responseIterator.forEachRemaining(item -> {
String str = String.format("user[id=%d, name=%s, address=%s]",
item.getId(), item.getName(), item.getAddress());
System.out.println(str);
});`
先启动provider，然后再起consumer，有时正常，有时还是报这个错，求解。
