需要添加spring-security-taglibs-3.0.5.RELEASE.jar包及其依赖包
对于spring security我只是初学者，原来只是想找一个用于权限验证的源码借鉴一下，结果一搜索，就搜到了spring security安全机制框架，我现在要将这个安全机制框架整合到我原来的ssh项目中去。 我现在只是在实验和学习阶段，没有深入的东西，用户名密码及其权限均是在xml文件配置的，以后有时间再学习一下如何和数据库交互，下面仅是简单的整合，将spring security的示例整合到项目中去。如果你是下载的spring security的发行包，会在其dist目录下找到一个spring-security-samples-tutorial-x.x.x.xxxxx.war的war包，我直接使用了这里的applicationContext-security.xml和jsp文件。 下面开始整合： 1.首先添加jar包依赖，我使用的maven来管理依赖包，只需添加下面依赖：
Xml代码 <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-core</artifactId> <version>3.0.5.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-web</artifactId> <version>3.0.5.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-config</artifactId> <version>3.0.5.RELEASE</version> </dependency>版本号自己控制，我使用的3.0.5.RELEASE版本，自己手动管理jar包依赖的，将dist目录下的除了war包和***-sources.jar外的所有jar包添加项目下。 2.在web.xml下配置spring security的过滤器和spring security的配置文件的位置，这里注意，在ssh框架整合spring security时，一定要将spring security的filter-mapping配置在struts2的filter-mapping之前，否则会出现如下错误：
Html代码 HTTP ERROR 404 Problem accessing /Struts_Spring_Maven/spring_security_login. Reason: There is no Action mapped for namespace [/] and action name [spring_security_login] associated with context path [/Struts_Spring_Maven].struts2和spring security配置如下：
Xml代码 <context-param> <param-name>contextConfigLocation</param-name> <param-value> classpath:applicationContext.xml /WEB-INF/applicationContext-security.xml </param-value> </context-param> <!-- 配置Struts中心过滤器 --> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> <init-param> <param-name>actionPackages</param-name> <param-value>zwh.struts.maven.action</param-value> </init-param> </filter> <!-- 配置spring security的过滤器 --> <filter> <filter-name>springSecurityFilterChain</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> </filter> <!-- spring security的filter-mapping一定要配置struts的前面 --> <filter-mapping> <filter-name>springSecurityFilterChain</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- struts的filter-mapping --> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>3.添加applicationContext-security.xml文件，我是直接将示例项目中的文件直接拷贝到我的项目中去的，拷贝到WEB-INF目录下。文件内容如下：
Xml代码 <?xml version="1.0" encoding="UTF-8"?> <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-3.0.xsd"> <global-method-security pre-post-annotations="enabled"> <!-- AspectJ pointcut expression that locates our "post" method and applies security that way <protect-pointcut expression="execution(* bigbank.*Service.post*(..))" access="ROLE_TELLER"/> --> </global-method-security> <http use-expressions="true"> <intercept-url pattern="/secure/extreme/**" access="hasRole('ROLE_SUPERVISOR')"/> <intercept-url pattern="/secure/**" access="isAuthenticated()" /> <!-- Disable web URI authorization, as we're using <global-method-security> and have @Secured the services layer instead <intercept-url pattern="/listAccounts.html" access="isRememberMe()" /> <intercept-url pattern="/post.html" access="hasRole('ROLE_TELLER')" /> --> <intercept-url pattern="/**" access="permitAll" /> <form-login /> <logout /> <remember-me /> <!-- Uncomment to enable X509 client authentication support <x509 /> --> <!-- Uncomment to limit the number of sessions a user can have --> <session-management invalid-session-url="/timeout.jsp"> <concurrency-control max-sessions="1" error-if-maximum-exceeded="true" /> </session-management> </http> <!-- Usernames/Passwords are rod/koala dianne/emu scott/wombat peter/opal --> <authentication-manager> <authentication-provider> <password-encoder hash="md5"/> <user-service> <user name="rod" password="a564de63c2d0da68cf47586ee05984d7" authorities="ROLE_SUPERVISOR, ROLE_USER, ROLE_TELLER" /> <user name="dianne" password="65d15fe9156f9c4bbffd98085992a44e" authorities="ROLE_USER,ROLE_TELLER" /> <user name="scott" password="2b58af6dddbd072ed27ffc86725d7d3a" authorities="ROLE_USER" /> <user name="peter" password="22b5c9accc6e1ba628cedc63a72d57f8" authorities="ROLE_USER" /> </user-service> </authentication-provider> </authentication-manager> </beans:beans>从该文件中可以看到/secure路径下面的所有文件的访问需要登陆才能访问，而/secure/extreme路径下的所有文件的访问必须是超级用户，即具备ROLE_SUPERVISOR的角色。rod是超级用户，密码是koala，后面登陆需要使用。 4.在项目目录下创建secure目录和secure/extreme目录，并在这些目录下放一些需要验证才能访问的页面，我为了省事，将示例中jsp页面直接拷贝到项目目录下了。 5.下面将该项目添加到tomcat中去，运行，访问http://localhost:8080/项目名称/secure/index.jsp 。这时你发现并不是展示出你访问的页面，而是出现了一个登陆页面。如下： 6.输入用户名rod和密码koala，提交，这时就可以看到了你想要访问的页面了。 7.如果遇到如下问题：
Html代码 The absolute uri: http://www.springframework.org/security/tags cannot be resolved in either web.xml or the jar files deployed with this application.对于maven还需要添加如下依赖
Xml代码 <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-taglibs</artifactId> <version>3.0.5.RELEASE</version> </dependency>自己管理jar包需要添加spring-security-taglibs-3.0.5.RELEASE.jar包及其依赖包。
