This is only to save the startup time during the development process. In the deployment to the actual environment, it is not necessary to set default-lazy-init to true. After all, deployment to the actual environment is not a frequent issue. It is not a big problem to start every 1 minute, and it can improve server Efficiency --> <! -- Configure the data source --> <bean id = "dataSource" class = "org. springframework. jdbc. datasource. driverManagerDataSource "> <property name =" driverClassName "> <value> com. mysql. jdbc. driver </value> </property> <property name = "url"> <value> jdbc: mysql: // localhost/ssh?
