Build springmvc+hibernate+sping Frame

1. The first required jar is imported into the project;
   

2. Thespring configuration file is introduced in Web. XML, the project initiates the initialization of the spring controller, Spingbean injection, <!--controller method call rule definition--><!-- Page view layer basic information Settings--><!--servlet mapping list, where the servlet of all control layer controllers is defined--

Hibernate configuration is mainly the!!! ：

The package to scan (hibernate annotations);

data source; sessionfactory;

Hibernatetemplate;

Configure things (Get data does not start a transaction)

NOTE 2:

<!--introduce a property file--
<context:property-placeholder location= "Classpath:dbconfig.properties"/>

This gets the value ${JDBC.URL.JEECG}

Db.properties Content
