to create consumer repeatedly and communicate with the server frequently, but it is not a problem in applications with low performance requirements.2, do not use Jmstemplate, manually create a consumer, at this time can make full use of prefetch mechanism. In conjunction with multithreading, each thread has its own consumer, which maximizes the speed advantage of MQ at high throughput.PS: How to see the prefetch mechanism of ACTIVEMQ?The default valu

Convenient tool in C ++ 11-chrono Library (processing date and time) Chrono is the name of a header, but also of a sub-namespace: All the elements in this header (partition t for the common_type specializations) are not defined directly under the std namespace (like most of the standard library) but under the std: chrono namespace. The elements in this header deal with
