summaryThe escaped pointer variable itself is also allocated in the heap space, so the function can return the address of the local variable. At this time, the local variable is equivalent to the local pointer variable. When escaping, the pointer variable itself is also allocated in the heap space, so it can return its address.The memory of sta ...

Apache Dubbo has the communication mode of injvm, which can avoid the delay caused by the network and does not occupy the local port.
