<!-- 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 >

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

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
