inherits or implements the corresponding classes or interfaces in a normal class, you can get the ApplicationContext object of spring. However, it is important to note that the normal Java class that inherits or implements these abstract classes or interfaces must be configured in the spring's configuration file (that is, the Application-context.xml file), otherwise the obtained ApplicationContext object will be null. The following shows how to get

The Java "No bean named ' sessionfactory ' is defined" occurs frequently in the SHH framework or in the implementation of Hibernate SPING+JPA with annotation; The reason for the exception is the sessionfactory bean could not be found .The reasons are as follows:1, in Many-to-one or Many-to-many time we set the fetchtype= "lazy" delay loading. Solution to the prob
