Maven+SSM+Shiro整合配置

效果图:



简介

1.shiro是用于权限控制还有对密码加密的框架,同时可以控制尝试登入次数,超出将对用户锁定

2.shiro的运行轨迹是用户登入以后,shiro会自动查询用户的角色以及权限,并将用户信息保存到session里,当用户在进行访问资源时候,会根据之前对资源权限的定义,检查用户是否具有这个权限,比如访问/allUser,访问需要admin的角色,shiro会根据登入用户的信息,检查用户是否具有admin的角色

3.shiro1.2提供了passwordService,对密码加密更加方便

4.shiro的shiroFilter配置,如果是访问其他已存在的页面被拦截到登录页面,登录后就会跳转到之前的页面;如果是直接访问登录页面或者是通过退出登录到登录页面,再次登录就会跳转到“/”

5.Spring MVC的json传输,可以自动的根据属性名称,将json和对象自动转换

6.实例环境的搭建 http://blog.csdn.net/zzhao114/article/details/54958339

7.实例用到的mybatis多表联立 http://blog.csdn.net/zzhao114/article/details/55106270

遇到的问题及解决

1.shiro定义的权限控制无效的问题

在web.xml中需要将shiro的配置放在是Spring MVC的配置之前,shiro的过滤集为<url-pattern>/*</url-pattern>,Spring MVC的过滤集为<url-pattern>/</url-pattern>

2.使用shiro加密,用户登入密码匹配一直不成功问题

自定义的userRealm,不能通过注释的方式自动注册bean,不然不能讲使用passwordService的加密方式对密码正确的匹配,需要在配置文件里配置

<!-- 注册自定义的Realm,并把密码匹配器注入,使用注解的方式自动注解会无法正确匹配密码 -->
	<bean id="userRealm" class="com.shiro.UserRealm">
        <property name="credentialsMatcher" ref="passwordMatcher"/>
        <property name="cachingEnabled" value="false"/>
    </bean>

3.shiro的注解无效问题

需要在Spring MVC的配置文件中启动shiro注解

<!--启用shiro注解 -->
	<bean
		class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"
		depends-on="lifecycleBeanPostProcessor">
		<property name="proxyTargetClass" value="true" />
	</bean>
	<bean
		class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
		<property name="securityManager" ref="securityManager" />
	</bean>

4.使用注解后,无权限异常的问题

如果没有对资源的访问权限,并不是跳转到在shiro配置文件中的<property name="unauthorizedUrl" value="/unauthorized" />设置的url,而是抛出无权限的异常,需要在Spring MVC的配置文件中加入即可解决

<!-- shiro为集成springMvc 拦截异常,使用注解时无权限的跳转 -->
	<bean
		class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
		<property name="exceptionMappings">
			<props>
				<!-- 这里你可以根据需要定义N多个错误异常转发 -->
				<prop key="org.apache.shiro.authz.UnauthorizedException">redirect:/unauthorized</prop>
				<prop key="org.apache.shiro.authz.UnauthenticatedException">redirect:/unauthorized</prop>
				<prop key="java.lang.IllegalArgumentException">/error</prop>  <!-- 参数错误(bizError.jsp) -->
				<prop key="java.lang.Exception">/error</prop>  <!-- 其他错误为'未定义错误'(unknowError.jsp) -->
			</props>
		</property>
	</bean>

5.对静态资源设置不须任何权限的问题

需要同时在Spring MVC和shiro的配置文件中配置。

Spring MVC:

<!-- 静态资源访问(不拦截此目录下的东西的访问) -->
	<mvc:resources location="/js/" mapping="/js/**" />
	<mvc:resources location="/icon/" mapping="/icon/**" />
Shiro:

/icon/**=anon
/js/**=anon

6.shiro中的successUrl不生效的问题

successUrl配置只是做为一种附加配置,只有session中没有用户请求地址时才会使用successUrl。系统默认的是认证成功后跳转到上一次请求的路径,如果是首次请求,那shiro就会跳转到默认虚拟路径“/”,也就是跳转到index.jsp。

7.使用json问题

需要在Spring MVC加入json转换器

<!-- 启动SpringMVC的注解功能,完成请求和注解POJO的映射 -->
	<bean
		class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
		<property name="messageConverters">
			<list>
				<ref bean="jsonMapping" />     <!-- JSON转换器 -->
			</list>
		</property>
	</bean>

	<!--避免IE执行AJAX时,返回JSON出现下载文件 -->
	<bean id="jsonMapping"
		class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
		<property name="supportedMediaTypes">
			<list>
				<value>text/html;charset=gbk</value>
			</list>
		</property>
	</bean>
需要的jar包:

<!-- 映入JSON -->
		<dependency>
			<groupId>org.codehaus.jackson</groupId>
			<artifactId>jackson-mapper-asl</artifactId>
			<version>1.9.13</version>
		</dependency>


拓展

1.登入的几种异常

try {
			subject.login(token);
		} catch (UnknownAccountException uae) {
			logger.info("用户名为【" + token.getPrincipal() + "】不存在");
		} catch (IncorrectCredentialsException ice) {
			logger.info("用户名为【 " + token.getPrincipal() + " 】密码错误!");
		} catch (LockedAccountException lae) {
			logger.info("用户名为【" + token.getPrincipal() + " 】的账户锁定,请联系管理员。");
		} catch (DisabledAccountException dax) {
			logger.info("用户名为:【" + token.getHost() + "】用户已经被禁用.");
		} catch (ExcessiveAttemptsException eae) {
			logger.info("用户名为:【" + token.getHost() + "】的用户登录次数过多,有暴力破解的嫌疑.");
		} catch (ExpiredCredentialsException eca) {
			logger.info("用户名为:【" + token.getHost() + "】用户凭证过期.");
		} catch (AuthenticationException ae) {
			logger.info("用户名为:【" + token.getHost() + "】用户验证失败.");
		} catch (Exception e) {
			logger.info("别的异常信息。。。。具体查看继承关系");
		}

2.filterChainDefinitions的解释

<property name="filterChainDefinitions">      
            <value>      
                <!-- anon表示此地址不需要任何权限即可访问 -->    
                /static/**=anon    
                <!-- perms[user:query]表示访问此连接需要权限为user:query的用户 -->    
                /user=perms[user:query]    
                <!-- roles[manager]表示访问此连接需要用户的角色为manager -->    
                /user/add=roles[manager]    
                /user/del/**=roles[admin]    
                /user/edit/**=roles[manager]    
                <!--所有的请求(除去配置的静态资源请求或请求地址为anon的请求)都要通过登录验证,如果未登录则跳到/login-->      
                /** = authc    
            </value>      
        </property> 

3.shiro在jsp页面的用法

配置:

<%@ taglib prefix="shiro" uri="http://shiro.apache.org/tags" %>
用法:
<shiro:authenticated>用户已经登录显示此内容</shiro:authenticated>    
    <shiro:hasRole name="manager">manager角色登录显示此内容</shiro:hasRole>    
    <shiro:hasRole name="admin">admin角色登录显示此内容</shiro:hasRole>    
    <shiro:hasRole name="normal">normal角色登录显示此内容</shiro:hasRole>          
    <shiro:hasAnyRoles name="manager,admin">** manager or admin 角色用户登录显示此内容**</shiro:hasAnyRoles>    
    <shiro:principal/>显示当前登录用户名    
    <shiro:hasPermission name="add">add权限用户显示此内容</shiro:hasPermission>    
    <shiro:hasPermission name="user:query">query权限用户显示此内容<shiro:principal/></shiro:hasPermission>    
    <shiro:lacksPermission name="user:del"> 不具有user:del权限的用户显示此内容 </shiro:lacksPermission> 

具体的配置:

数据库:

user:id、username、password

mapping_UR:userid(FK:user.id)、roleid(FK:role.id)

role:id、name
mapping_RP:roleid(FK:role.id)、permissionid(FK:permission.id)

permission:id、pname
