Two ways to configure Hibernate mapping files using spring

There are two ways to configure Hibernate mappings in spring to implement the

1: When the required mapping file is less, can be implemented by mappingresources

The specific implementation is as follows:

<property name= "Mappingresources" > <list> <value>com/yourcompany/model/teacher.hbm.xml</ Value> <value>com/yourcompany/model/Student.hbm.xml</value> <value>com/yourcompany/model/ School.hbm.xml</value> </list> </property>

The main thing is to use <value> </value> to list the location and name of your mapping file in <list></list>.

The advantages of this realization: more intuitive, easy to understand, the drawback is: if the mapping file too much, one is too much repetition of code, the second is if there is a wrong place to find.

So we can use the following method, just give spring a folder, other things, let Spring do.

2: When there are too many files to map, we can use: Mappingdirectorylocations to implement

Specific as follows:

You can specify or change the Classpath:/com/yourcompany to a folder location by Classpath: web-inf/modelmappings

<property name= "Mappingdirectorylocations" > <list> <value>classpath:/com/yourcompany/model/< /value> </list> </property>
