ssm整合：Spring层

1.配置Spring整合Mybatis，我们这里的数据源使用c3p0连接池

2.编写Spring整合Mybatis的相关配置文件:spring-dao.xml

<?xml version="1.0" encoding="UTF-8"?>
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/aop
        https://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd">

    
    
    

    
        
        
        
        


        
        

        

        

        
    

    
        

        
    

    

        

        
    

3.spring整合service层

spring-service.xml

<?xml version="1.0" encoding="UTF-8"?>
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/aop
        https://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd">


    

    
        
    

    

        
    

 applicationContext.xml:
