<!-- 配置shiro过滤器 --> < bean id = "shiroFilter" class = "org.apache.shiro.spring.web.ShiroFilterFactoryBean" > <!-- 表示现在要配置的是一个安全管理器 --> < property name = "securityManager" ref = "securityManager" /> <!-- 出现错误之后的跳转路径的配置 --> < property name = "loginUrl" value = "/login.html" /> <!-- 认证失败之后的跳转路径页面 --> < property name = "unauthorizedUrl" value = "/login.html" /> <!-- 登录成功之后的跳转访问路径 --> < property name = "successUrl" value = "/pages/welcome.jsp" /> < property name = "filterChainDefinitions" > < value > /admin=authc /logout=logout /xxxxxx=user </ value > </ property > </ bean > |
Properties属性文件可以这样写

shiro.loginUrl=/login.html shiro.unauthorizedUrl=/login.html shiro.successUrl=/pages/welcome.jsp shiro.filterChainDefinitions=/admin=authc \n\ /logout=logout \n\ /info=authc |
后面的等号不需要转义,\n表示值中的换行,再加个转义符\表示值还没结束,这样就没问题了

< bean id = "shiroFilter" class = "org.apache.shiro.spring.web.ShiroFilterFactoryBean" > < property name = "securityManager" ref = "securityManager" /> < property name = "loginUrl" value = "${shiro.loginUrl}" /> < property name = "unauthorizedUrl" value = "${shiro.unauthorizedUrl}" /> < property name = "successUrl" value = "${shiro.successUrl}" /> < property name = "filterChainDefinitions" > < value >${shiro.filterChainDefinitions}</ value > </ property > </ bean > |
处理properties文件中key包含空格和等号的情况
在properties文件中都是以key=value的方式存储的,在java代码中用java.util.Properties的load方法,存储在一个map中,当key中有空格和等号的时候,要用\(斜杠)进行转义,而用xml的话,就没有转义这么麻烦了,所以推荐使用xml了。
处理方案

以上为个人经验,希望能给大家一个参考,也希望大家多多支持服务器之家。
