In development mode, you can use http: // host: port/wls-cat for access. It can help solve class conflicts or study the classloader structure of weblogic. Here are two articles for reference.

T *CachedObj ::freeStore = 0;template const std::size_t CachedObj ::chunk = 24; As usual, for static members of the class template, different static members are used for each type to instantiate the CachedObj class. Initialize the chunk to any value. In this example, the value is 24. Initialize the freeStore pointer to 0, indicating that the freeStore pointer is empty at the beginning. The alloc_mem mem
