一、web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"

二、applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.2.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">

<!-- <bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<property name="basename" value="classpath:org/springframework/security/messages"/>
</bean> --> </beans>
三、spring-security.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:security="http://www.springframework.org/schema/security"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/security
http://www.springframework.org/schema/security/spring-security-3.2.xsd"> <!-- Spring-Security 的配置 -->
<security:http auto-config="true" use-expressions="true"
access-denied-page="/auth/denied">
<security:intercept-url pattern="/auth/login"

<bean id="customUserDetailsService"

<!-- 访问决策器，决定某个用户具有的角色，是否有足够的权限去访问某个资源 -->
<bean id="customAccessDecisionManager"
class="com.candy.common.utils.security.CustomAccessDecisionManager"></bean>
<!-- 资源源数据定义，即定义某一资源可以被哪些角色访问 -->
<bean id="customSecurityMetadataSource"
class="com.candy.common.utils.security.CustomSecurityMetadataSource"></bean>
</beans>
spring-security.xml命名空间配置，官方提供了两种配置方案
第一种、命名空间用beans开头，但是在配置中一直需要用<security:*>来配置。
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:security="http://www.springframework.org/schema/security"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/security
http://www.springframework.org/schema/security/spring-security.xsd">
...
</beans>
第二种、命名空间用security开头，在配置中不需要security前缀，但是bean的配置需要用<beans:bean>配置。
<beans:beans xmlns="http://www.springframework.org/schema/security"
xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/security
http://www.springframework.org/schema/security/spring-security.xsd">
...
</beans:beans>
四、mvc-servlet.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:p="http://www.springframework.org/schema/p" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

http://www.springframework.org/schema/context/spring-context-3.2.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd"> <!-- 激活spring的注解. -->
<context:annotation-config /> <!-- 扫描注解组件并且自动的注入spring beans中. 例如,他会扫描@Controller 和@Service下的文件.所以确保此base-package设置正确. -->
<context:component-scan base-package="com.candy.controller" /> <!-- 配置注解驱动的Spring MVC Controller 的编程模型.注:次标签只在 Servlet MVC工作! -->
<!-- SpringMVC通过JACKSON包，将responsebody中的对象转换为JSON -->
<mvc:annotation-driven>
<mvc:message-converters register-defaults="false">
