shiro权限控制《二》+spring

shiro+spring web项目

1.在web.xml中配置filter

    <!-- Apache Shiro -->
    <filter>
        <filter-name>shiroFilter</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
        <init-param>
            <param-name>targetFilterLifecycle</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>shiroFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

2.配置文件spring-shiro.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="

    }
    
    public String getMessageParam() {
        return messageParam;
    }
    
    /**
     * 登录成功之后跳转URL
     */
    public String getSuccessUrl() {
        return super.getSuccessUrl();
    }
    
    @Override
    protected void issueSuccessRedirect(ServletRequest request,
            ServletResponse response) throws Exception {
//        Principal p = UserUtils.getPrincipal();
//        if (p != null && !p.isMobileLogin()){
             WebUtils.issueRedirect(request, response, getSuccessUrl(), null, true);
//        }else{
//            super.issueSuccessRedirect(request, response);
//        }
    }

    /**
     * 登录失败调用事件
     */
    @Override
    protected boolean onLoginFailure(AuthenticationToken token,
            AuthenticationException e, ServletRequest request, ServletResponse response) {
        String className = e.getClass().getName(), message = "";
        if (IncorrectCredentialsException.class.getName().equals(className)
                || UnknownAccountException.class.getName().equals(className)){
            message = "用户或密码错误, 请重试.";
        }
        else if (e.getMessage() != null && StringUtils.startsWith(e.getMessage(), "msg:")){
            message = StringUtils.replace(e.getMessage(), "msg:", "");
        }
        else{
            message = "系统出现点问题，请稍后再试！";
            e.printStackTrace(); // 输出到控制台
        }
        request.setAttribute(getFailureKeyAttribute(), className);
        request.setAttribute(getMessageParam(), message);
        return true;
    }
    
}

当用户登录的时候，会到过滤器里，它有什么作用呢，最主要的作用是：调用createToken()方法返回token，其中token中包含着用户登录所需要的信息，然后到realms认证方法的时候，就可以取出token，然后查库进行操作。

不加这个过滤器，他会默认用org.apache.shiro.web.filter.authc.FormAuthenticationFilter，如果有个性需求（比如登录的时候要加一个短信验证码啊什么之类的），你就需要自己实现表单过滤器。本身的org.apache.shiro.web.filter.authc.FormAuthenticationFilter，只有用户名和密码之类常用的。

5.Controller类，shiro权限

@RequiresPermissions("sys:menu:view")
@RequestMapping("list"})
public String list(Model model) {
　　return "/list";

}

url对应的权限配置

6.jsp页面

Jsp页面添加：

<%@ tagliburi="http://shiro.apache.org/tags" prefix="shiro" %>

 

标签名称	标签条件（均是显示标签内容）
<shiro:authenticated>	登录之后
<shiro:notAuthenticated>	不在登录状态时
<shiro:guest>	用户在没有RememberMe时
<shiro:user>	用户在RememberMe时
<shiro:hasAnyRoles name="abc,123" >	在有abc或者123角色时
<shiro:hasRole name="abc">	拥有角色abc
<shiro:lacksRole name="abc">	没有角色abc
<shiro:hasPermission name="abc">	拥有权限资源abc
<shiro:lacksPermission name="abc">	没有abc权限资源
<shiro:principal>	显示用户身份名称

 <shiro:principal property="username"/>     显示用户身份中的属性值

7.配置文件解释：

　　1.自定义过滤器　　

    <!-- Shiro权限过滤过滤器定义 -->
    <bean name="shiroFilterChainDefinitions" class="java.lang.String">
        <constructor-arg>
            <value>
                /static/** = anon
                /userfiles/** = anon
                ${adminPath}/cas = cas
                ${adminPath}/login = authc
                ${adminPath}/logout = logout
                ${adminPath}/** = user
                /act/rest/service/editor/** = perms[act:model:edit]
                /act/rest/service/model/** = perms[act:model:edit]
                /act/rest/service/** = user
                /ReportServer/** = user
            </value>
        </constructor-arg>
    </bean>

过滤器简称    对应的java类
anon    org.apache.shiro.web.filter.authc.AnonymousFilter
authc    org.apache.shiro.web.filter.authc.FormAuthenticationFilter
authcBasic    org.apache.shiro.web.filter.authc.BasicHttpAuthenticationFilter
perms    org.apache.shiro.web.filter.authz.PermissionsAuthorizationFilter
port    org.apache.shiro.web.filter.authz.PortFilter
rest    org.apache.shiro.web.filter.authz.HttpMethodPermissionFilter
roles    org.apache.shiro.web.filter.authz.RolesAuthorizationFilter
ssl    org.apache.shiro.web.filter.authz.SslFilter
user    org.apache.shiro.web.filter.authc.UserFilter
logout    org.apache.shiro.web.filter.authc.LogoutFilter

anon:例子/admins/**=anon 没有参数，表示可以匿名使用。
authc:例如/admins/user/**=authc表示需要认证(登录)才能使用，FormAuthenticationFilter是表单认证，没有参数 
perms：例子/admins/user/**=perms[user:add:*],参数可以写多个，多个时必须加上引号，并且参数之间用逗号分割，例如/admins/user/**=perms["user:add:*,user:modify:*"]，当有多个参数时必须每个参数都通过才通过，想当于isPermitedAll()方法。
user:例如/admins/user/**=user没有参数表示必须存在用户, 身份认证通过或通过记住我认证通过的可以访问，当登入操作时不做检查

1、在applicationContext-shiro.xml中配置filter规则
    <!--商品查询需要商品查询权限  -->
    /items/queryItems.action = perms[item:query]
2、用户在认证通过后，请求/items/queryItems.action
3、被PermissionsAuthorizationFilter拦截，发现需要“item:query”权限
4、PermissionsAuthorizationFilter调用realm中的doGetAuthorizationInfo获取数据库中正确的权限
5、PermissionsAuthorizationFilter对item:query 和从realm中获取权限进行对比，如果“item:query”在realm返回的权限列表中，授权通过。

　　2.shiro安全过滤器

    <!-- 安全认证过滤器 -->
    <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
        <property name="securityManager" ref="securityManager" /><!-- 
        <property name="loginUrl" value="${cas.server.url}?service=${cas.project.url}${adminPath}/cas" /> -->
        <property name="loginUrl" value="${adminPath}/login" />
        <property name="successUrl" value="${adminPath}?login" />
        <property name="filters">
            <map>
                <entry key="cas" value-ref="casFilter"/>
                <entry key="authc" value-ref="formAuthenticationFilter"/>
            </map>
        </property>
        <property name="filterChainDefinitions">
            <ref bean="shiroFilterChainDefinitions"/>
        </property>
    </bean>

loginUrl:登录地址

successUrl:成功登录地址

filterChainDefinitions：自定义的过滤器添加到这儿，等等的参数

 

流程：

1.通过浏览器访问路径，配置文件查看，是否需要认证等，如果不需要，直接访问controller

2.如果需要认证，通过配置文件的loginUrl，跳到这个地址，输入用户名、密码等

3.登录：1.访问自定义的form表单过滤器FormAuthenticationFilter（自己起的名字和shiro一样了，所以。。）的createToken方法，装配token；

　　　　 如果没有自定义表单过滤器，默认的FormAuthenticationFilter会自动装配表单token

　　　　2.访问自定义realms的认证方法doGetAuthenticationInfo()，查库（或者缓存），判断用户名和密码是否正确。

4.如果登录之后访问的url，通过配置文件里的配置需要权限：

　　调用自定义realms的授权方法：doGetAuthorizationInfo()，查库（或者缓存），查出用户权限，判断是否拥有权限，没权访问，跳到响应的refuse配置的路径，有权访问，跳到响应的url
