SpringMVC4零配置--SpringSecurity相关配置【SpringSecurityConfig】

 SpringSecurity的配置相对来说有些复杂，如果是完整的bean配置，则需要配置大量的bean，所以xml配置时使用了命名空间来简化配置，同样，spring为我们提供了一个抽象类WebSecurityConfigurerAdapter和一个注解@EnableWebMvcSecurity，达到同样减少bean配置的目的，如下：

 

applicationContext-SpringSecurityConfig.xml

<http security="none" pattern="/static/**" />
	<http security="none" pattern="/**/*.jsp" />

	<http auto-config='true' access-decision-manager-ref="accessDecisionManager" access-denied-page="/login"
		use-expressions="true">
		<logout logout-url="/logout" invalidate-session="true"
			logout-success-url="/login" />


		<form-login login-page="/login" authentication-failure-url="/login?error=1"
			login-processing-url="/j_spring_security_check" password-parameter="j_password"
			username-parameter="j_username" />


		<intercept-url pattern="/**/*.do*" access="hasRole('ROLE_USER')" />
		<intercept-url pattern="/**/*.htm" access="hasRole('ROLE_ADMIN')" />

		<session-management session-fixation-protection="changeSessionId">
			<concurrency-control max-sessions="1"
				expired-url="/access/sameLogin.do" />
		</session-management>

		<remember-me key="webmvc#FD637E6D9C0F1A5A67082AF56CE32485"
			remember-me-parameter="remember-me" />
	</http>

	<!-- 启用表达式 为了后面的投票器做准备 -->
	<beans:bean
		class="org.springframework.security.web.access.expression.DefaultWebSecurityExpressionHandler"
		id="expressionHandler" />
	<beans:bean
		class="org.springframework.security.web.access.expression.WebExpressionVoter"
		id="expressionVoter">
		<beans:property name="expressionHandler" ref="expressionHandler" />
	</beans:bean>

	<!-- Automatically receives AuthenticationEvent messages -->
	<beans:bean id="loggerListener"
		class="org.springframework.security.authentication.event.LoggerListener" />
	<beans:bean id="authorizationListener"
		class="org.springframework.security.access.event.LoggerListener" />

	<!-- 认证管理器，使用自定义的UserDetailsService，并对密码采用md5加密 -->
	<authentication-manager>
		<authentication-provider user-service-ref="userService">
			<password-encoder hash="md5" />
		</authentication-provider>
	</authentication-manager>





	<beans:bean id="userService" class="web.security.CP_UserDetailsService" />

	<beans:bean id="accessDecisionManager"
		class="org.springframework.security.access.vote.AffirmativeBased">
		<beans:property name="decisionVoters">
			<beans:list>
				<beans:bean class="org.springframework.security.access.vote.RoleVoter" />
				<beans:bean
					class="org.springframework.security.access.vote.AuthenticatedVoter" />
				<beans:ref bean="expressionVoter" />
			</beans:list>
		</beans:property>
	</beans:bean>

SpringSecurityConfig.java

	}

	@Override

	}

	/*

楼主你的抠抠号多少，请教一下这个如果权限都配置在数据库里的，如何写这些代码？我的抠抠359709421
