The support for hibernate in spring is very powerful. We can see from a simple example that we will also discuss the so-called lightweight container. First, we need to configure the data source. Generally, we have two methods to obtain the connection. First, we need to write the data source by ourselves.CodeObtain the connection. The second is to obtain the datasource from the JNDI environment and then generate a connection. In any case, since it
