spring security4.1.0基础配置

1.security.xml配置

(1) 配置一些不需要安全验证即可登录的资源:

<http pattern="/login.html" security="none"/>

(2)认证管理器,也就是确认用户名密码是否正确。

<authentication-manager erase-credentials="false"  alias="authenticationManager">
    <authentication-provider  ref="customAuthenticationProvider"   >
        <!-- 如果用户的密码采用加密的话,可以加点“盐” <password-encoder hash="md5" /> -->
    </authentication-provider>
</authentication-manager>

(3)配置收到HTTP请求时的安全验证配置:

	<!--http 标签属性中定义了 登录点,认证类,访问控制类-->
	<http auto-config="false" entry-point-ref="authenticationEntryPoint" authentication-manager-ref="authenticationManager" access-decision-manager-ref="customAccessDecisionManager">
		<csrf disabled="true"></csrf>
		<logout success-handler-ref="logoutSuccessHandler"></logout>
		<!-- 一部分允许所有用户访问的.do后台资源在此配置,AccessDecisionManage不再进行权限验证 -->
		<intercept-url pattern="/admin/**" access="ROLE_ADMIN"></intercept-url>
		<intercept-url pattern="/user/getCurrentUser.do" access="permitAll"></intercept-url>
		<!-- 其他所有资源要求进行访问权限验证 -->
		<intercept-url pattern="/**" access="isAuthenticated()"></intercept-url>
		<!--自定义实现用户名密码及验证码判断功能的Filter-->
		<custom-filter  ref="customUsernamePasswordAuthenticationFilter"  position="FORM_LOGIN_FILTER"/>
		<anonymous enabled="false"></anonymous>
	</http>

其中可以自定义实现功能的<b:bean>,比如“自定义实现用户名及密码验证判断功能的Filter”,它将class文件注入,

<!--自定义实现用户名密码及验证码判断功能的Filter,因为用户认证模块涉及了验证码,所以单独写了一个filter,这里这个类就只起了比对用户密码的功能 -->
	<b:bean id="customUsernamePasswordAuthenticationFilter" class="cn.topcheer.common.authority.springsec.CustomUsernamePasswordAuthenticationFilter">
		<b:property name="enableValidateCode" value="false"></b:property>
		<b:property name="authenticationManager" ref="authenticationManager"></b:property>
		<b:property name="authenticationFailureHandler" ref="failureHandler"></b:property>
		<b:property name="authenticationSuccessHandler" ref="successHandler"></b:property>
	</b:bean>

其中,<b:property>定义的是该类属性,<b:constuctor-arg></b:constructor-arg>是该类的构造方法;

(4)用户自定义过滤器

设定格式形如: 

<custom-filter  ref="customUsernamePasswordAuthenticationFilter"  position="过滤器假名"/>

 ” position”表示本过滤器,要替代其后的过滤器. "过滤器假名"指示了被替代的过滤器名; 除了” position”,还有”before” 与”after”两种方式。

分别表示将要把本过滤器挂在其后的过滤器前或后。 

标准过滤器假名和顺序
