SSM Learning-3. Adding the SPRINGMVC configuration

1. Create a new SPRINGMVC configuration file in the project Applicationcontext.xml

　　

2. Basic Configuration

[1]. Configure the data source

[2]. Integration of configuration and MyBatis

[3]. Configuring the MyBatis Scanner

[4]. Transaction control Configuration

The Applicationcontext.xml is configured as follows:

　　The configuration of the dbconfig.properties is as follows:

Jdbc.jdbcurl=jdbc:mysql://localhost:mysql port number/database name jdbc.driverclass=com.mysql.jdbc.driverjdbc.user= User name jdbc.password= password
