4、搭建Spring

4.1、 创建配置文件，添加c3p0数据源配置信息

      src/main/resources/applicationConfig.xml

copy

1. #application all config  
2.   
3. #jdbc c3p0  
4. jdbc.driver = com.mysql.jdbc.Driver  
5. jdbc.url = jdbc:mysql://localhost:3306/shop?useUnicode=true&characterEncoding=utf-8  
6. jdbc.username = root  
7. jdbc.password = 12345  

4.2、创建Spring配置文件

    src/main/resources/applicationContext.xml

copy

1. <?xml version="1.0" encoding="UTF-8"?>  
2. <beans xmlns="http://www.springframework.org/schema/beans"
