Answer 1

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" 
destroy-method="close" 
p:driverClass="com.mysql.jdbc.Driver"
p:jdbcUrl="jdbc:mysql://localhost:3306/ebuy?characterEncoding=utf-8" 
p:user="root" 
p:password="123456" />
p是个什么东西？正常的不是<bean><property name="driverClass" value="......."/>..........</bean>

Answer 2

不关这个事的吧，这个是直接复制老师的。关键是我在delete()的时候，出现了这个问题，是代码问题还是spring配置问题

Answer 3

@Transactional(readOnly=false)
