一个spring security拦截器的配置

首先肯定是要将spring security的包下载并包含在项目当中。

1. web.xml

<listener>
    		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    	</listener>
    
    	<filter>
    		<filter-name>filterChainProxy</filter-name>
    		<filter-class>
    			org.springframework.web.filter.DelegatingFilterProxy
    		</filter-class>
    	</filter>
    	<filter-mapping>
    		<filter-name>filterChainProxy</filter-name>
    		<url-pattern>/*</url-pattern>
    	</filter-mapping>

2. applicationContext.xml

<bean id="filterChainProxy"
    		class="org.springframework.security.util.FilterChainProxy">
    		<property name="filterInvocationDefinitionSource">
    			<value>
    				CONVERT_URL_TO_LOWERCASE_BEFORE_COMPARISON
    				PATTERN_TYPE_APACHE_ANT
    				/**=myFilter
    			</value>
    		</property>
    	</bean>
    
    	<bean id="myFilter" class="com.unews.test.MyFilter"></bean>

FilterChianProxy表示的是一系列的拦截器，按照在value当中定义的顺序前后执行。

3. MyFilter.java

package com.unews.test;
    
    import java.io.IOException;
    
    import javax.servlet.Filter;
    import javax.servlet.FilterChain;
    import javax.servlet.FilterConfig;
    import javax.servlet.ServletException;
    import javax.servlet.ServletRequest;
    import javax.servlet.ServletResponse;
    
    public class MyFilter implements Filter {
    	public void destroy() {
    		// TODO Auto-generated method stub
    
    	}
    
    	public void doFilter(ServletRequest arg0, ServletResponse arg1,
    			FilterChain arg2) throws IOException, ServletException {
    		System.out.println("111");
    	}
    
    	public void init(FilterConfig arg0) throws ServletException {
    		// TODO Auto-generated method stub
    
    	}
    
    }
