SSM - demo2 xml+ 注解的相关文章

spring Mvc 执行原理 及 xml注解配置说明 (六)

Spring MVC 执行原理 在 Spring Mvc 访问过程里,每个请求都首先经过 许多的过滤器,经 DispatcherServlet 处理; 一个Spring MVC工程里,可以配置多个的 dispatcherServlet ,每个 DispatcherServlet 可以对应多个的 HandlerMapping ,每个 HandlerMapping 可以有自己的 Interceptor (拦截器). 1. 请求首先 由 前端 DispatcherServlet 捕获: 2. Disp

XML序列化与反序列化+自定义XML注解框架XmlUtils

背景 前面一篇总结了Serializable的序列化与反序列化,现在接着总结XML.主要内容:XML基本的序列化与反序列化方法.一些注意事项.以及自定义了一个XML注解框架(简洁代码,解放双手). XML的序列化与反序列化 先与Serializable进行简单的对比: Serializable存储的文件,打开后无法正常查看,安全性高.xml文件可通过文本编辑器查看与编辑,可读性高(浏览器会格式化xml文件,更方便查看),安全性低: Serializable文件通过了签名,只能在自己的程序中反序列

SSM框架——以注解形式实现事务管理

上一篇博文<SSM三大框架整合详细教程>详细说了如何整合Spring.SpringMVC和MyBatis这三大框架.但是没有说到如何配置mybatis的事务管理,在编写业务的过程中,会需要进行事务处理,当需要执行多条插入语句时,如果前几条成功,而最后一条失败,那么我们需要回滚数据库操作,保持数据的一致性和完整性,此时,就需要利用DB的事务处理.事务是恢复和并发控制的基本单位. 简单来说,所谓的事务,是一个操作序列,这些操作要么都执行,要么都不执行,它是一个不可分割的工作单位. 事务应该具有4个

SSM框架中注解含义及应用场景小结

先说一下什么是组件扫描: 指定一个包路径,Spring会自动扫描该包及其子包所有组件类,当发现组件类定义前有特定的注解标记时,就将该组件纳入到Spring容器.等价于原有XML配置中的<bean>定义功能. 组件扫描可以替代大量XML配置的<bean>定义. 使用组件扫描,首先需要在XML配置中指定扫描类路径 <context:component-scan base-package = "org.example"/> 上面配置,容器实例化时会自动扫描
