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

	}

}
