SSM常用配置文件

SSM常用配置文件

因学习ssm框架时 需配置各种配置文件(配置地狱) 为了方便自己平时的使用 特此从各官网上找到各种配置文件的模板 总结成此博客

<aop:aspectj-autoproxy />有一个proxy-target-class属性,默认为false,表示使用jdk动态代理织入增强,当配为<aop:aspectj-autoproxy  poxy-target-class="true"/>时,表示使用CGLib动态代理技术织入增强。不过即使proxy-target-class设置为false,如果目标类没有声明接口,则spring将自动使用CGLib动态代理。-->
