Spring security;spring security Spring Security是一个能够为基于Spring的企业应用系统提供声明式的安全访问控制解决方案的安全框架。它提供了一组可以在Spring应用上下文中 配置的Bean，充分利用了Spring IoC，DI（控制反转Inversion of Control ,DI:Dependency Injection 依赖注入）和AOP（面向切面编程）功能，为应用系统提供声明式的安全访问控制功能，减少了为企业系统安全控制编写大量重复代码的工作。 外文名：Spring Security 原???? 名：Acegi Security 类???? 别：安全服务体系 所???? 属：Spring 项目 ;Brief ;Function;Advantage;Advantage;Advantage;Application;这是web.xml 配置文件 ！！！?xml?version=1.0?encoding=UTF-8?web-app?version=2.5?xmlns=?/xml/ns/javaee??xmlns:xsi=?/2001/XMLSchema-instance? ?xsi:schemaLocation=?/xml/ns/javaee?/xml/ns/javaee/web-app_2_5.xsd???!--?编码统一最好放最上面，最先加载，防止乱码--??????filter??????????filter-nameSet?Character?Encoding/filter-name??????????filter-class org.springframework.web.filter.CharacterEncodingFilter /filter-class??????????init-param??????????????param-nameencoding/param-name??????????????param-valueUTF-8/param-value??????????/init-param??????????init-param??????????????param-nameforceEncoding/param-name??????????????param-valuetrue/param-value!--?强制进行转码?--??????????/init-param/filterfilter-mapping??????????filter-nameSet?Character?Encoding/filter-name??????????url-pattern/*/url-pattern/filter-mapping??;!--?然后接着是SpringSecurity必须的filter?优先配置，让SpringSecurity先加载，防止SpringSecurity拦截失效--??????filter??????????filter-namespringSecurityFilterChain/filter-name??????????filter-class org.springframework.web.filter.DelegatingFilterProxy /filter-class??????/filter????????filter-mapping??????????filter-namespringSecurityFilterChain/filter-name??????????url-pattern/*/url-pattern??????/filter-mapping??????welcome-file-list??????????welcome-fileindex.jsp/welcome-file ?????/welcome-file-list???;!--???spring需要加载的配置文件??--??????context-param??????????param-namecontextConfigLocation/param-name??????????param-value??????WEB-INF/classes/applicationContext.xml,??????WEB-INF/spring3-servlet.xml,??????WEB-INF/spring-security.xml??????????/param-value??????/context-p
