See the question: is the single case beans in the Spring framework thread safe? The spring framework does not encapsulate any multithreaded encapsulation of a single instance bean. Threading security and concurrency issues for a single bean need to be done by the developer themselves. But in fact, most spring beans do not have mutable states (such as the Serview class and DAO classes), so in some ways sprin

Thread-Safety (thread security) means that the Code still works normally when it is executed by multiple threads at the same time. This is especially true when multiple threads need to access the same shared data space. Only one thread can be satisfied. Multi-threaded execution is in a shared address space, and each thread can access the memory space of other thr
