database connection pool selection algorithm By default, database connections can be configured automatically using the DataSource pool. Here is an algorithm for selecting a specific implementation: because of the performance and concurrency of the Tomcat data source connection pool, we always use it preferentially when Tomcat is available. If HIKARICP is available, we will use it. If Commons DBCP is available, we will use it, but it is not recommended in the production environment. Finally, if

The Spring boot configuration file is available in two formats: Application.properties and APPLICATION.YML. Only one of the two profiles needs to be used.There are some differences in the syntax of the two configuration files, as follows1. Application.propertiesServer.port = 8080--Tomcat portServer.context-path =/webname--URL path2. Application.ymlServerport:8080--Tomcat port, note that there are spaces aft

Springboot officially recommends that we use spring-boot-starter-parent. spring-boot-starter-parent contains the following information: 1. Use Java 6 for compilation 2. UTF-8 encoding 3. implemented a general testing framework (JUnit, Hamcrest, Mockito ). 4. SMART Resource Filtering 5. intelligent plug-in configuration

For example, when you link a database, you need to use some or-mapping middleware, such as

integrity constraints that are defined on the data. Isolation (Isolation): There may be multiple transactions executing concurrently in the same environment, and each transaction should be performed independently. The effect of serially executing a series of transactions should be the same as executing them concurrently. This requires two things: During the execution of a transaction, the intermediate (possibly inconsistent) state of the data should not be exposed to all other transactions. T
