spring-security3 配置和使用 （一）（转载）
<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

</beans:beans>

3、然后在web.xml中添加配置,内容如下:

Xml代码?

<!--?spring?security??-->???????

? <context-param>????????

?????? <param-name>contextConfigLocation</param-name>??????????

?????? <param-value>??????????????classpath*:/applicationContext*.xml ??????????</param-value>??????

?</context-param>????????

<filter>?????????

?????? <filter-name>springSecurityFilterChain</filter-name>?????????

????? <filter-class>??????????????org.springframework.web.filter.DelegatingFilterProxy ??????????</filter-class>?????

</filter>??????

<filter-mapping>??????????

??? <filter-name>springSecurityFilterChain</filter-name>??????????

?? <url-pattern>/*</url-pattern>??????

?? </filter-mapping>?????

????????? <listener>?????????

????????????? <listener-class>??????????????org.springframework.web.context.ContextLoaderListener ????????

? </listener-class>??????</listener>??

<!-- spring security -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath*:/applicationContext*.xml
</param-value>
</context-param>

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

配置起来很简单,由于我的security是整合到现有项目中的.一些jar可能已经存在. 单独做demo的朋友配置的时候可能会出现问题.

本想分开发挣点积分..但怕大家看起来累.. 就发到一起吧.. (*^__^*)

使用篇

1、建立login.jsp页面.内容如下:

Html代码?

<form?action="<%=path?%>/j_spring_security_check"?method="post">??????????USERNAME:<input?type="text"?name="j_username"?value="${sessionScope['SPRING_SECURITY_LAST_USERNAME']}"?/><br/>??????????PASSWORD:<input?type="password"?name="j_password"?value=""?/><br/>????????

?<input?type="checkbox"?name="_spring_security_remember_me"?/>两周之内不必登陆<br/>????????

?<input?type="submit">????? ??????

</form>??

<form action="<%=path %>/j_spring_security_check" method="post">
USERNAME:<input type="text" name="j_username" value="${sessionScope['SPRING_SECURITY_LAST_USERNAME']}" /><br/>
PASSWORD:<input type="password" name="j_password" value="" /><br/>
<input type="checkbox" name="_spring_security_remember_me" />两周之内不必登陆<br/>
<input type="submit">
</form>

j_spring_security_check : 为security验证中心(不知道怎么说合适.暂时这么理解吧..).
j_username: 验证用户名;
j_password: 验证密码;
${sessionScope['SPRING_SECURITY_LAST_USERNAME']}:使用最后一次登录用户名.
_spring_security_remember_me:记住我...
