Spring provides two types of transaction management: programmatic and declarative. Programming, flexible, but with a large amount of code, there are more repeated code; declarative is more flexible than programming. The main programming method is transactionTemplate. Some commit, rollback, and a series of transaction object definitions are omitted, which need to be injected into the transaction management object. Declarative: mainly uses TransactionPr
