ZhXZhao opened a new issue, #715:
URL: https://github.com/apache/rocketmq-clients/issues/715
### Before Creating the Enhancement Request
- [X] I have confirmed that this should be classified as an enhancement
rather than a bug/feature.
### Programming Language of the Client
Java
### Summary
java sdk SimpleConsumerExample示例代码增加对receive方法的异常捕获
### Motivation
在触发服务端限流等异常事件时，receive方法会抛出异常，当限流恢复时，consumer不会自愈
### Describe the Solution You'd Like
示例代码增加对receive方法的异常捕获
```
// Receive message, multi-threading is more recommended.
do {
List<MessageView> messages = null;
try {
messages = consumer.receive(maxMessageNum,
invisibleDuration);
}catch (Throwable t) {
log.error("*****", t);
}
log.info("Received {} message(s)", messages.size());
for (MessageView message : messages) {
final MessageId messageId = message.getMessageId();
try {
consumer.ack(message);
log.info("Message is acknowledged successfully,
messageId={}", messageId);
} catch (Throwable t) {
log.error("Message is failed to be acknowledged,
messageId={}", messageId, t);
}
}
} while (true);
```
