filter自定义过滤器  增加了 对验证码的校验

package com.youxiong.filter;

import com.youxiong.shiro.usernamepasswordkaptchatoken;
import org.apache.shiro.authc.authenticationtoken;
import org.apache.shiro.subject.subject;
import org.apache.shiro.web.filter.authc.formauthenticationfilter;

import javax.servlet.servletrequest;
import javax.servlet.servletresponse;
import javax.servlet.http.httpservletrequest;
import javax.servlet.http.httpsession;

public class formvalid extends formauthenticationfilter {

    private string kaptcha = "kaptcha_session_key";

    public formvalid() {
        super();
    }

    //用户未登录
 /*   @override
    protected boolean onaccessdenied(servletrequest request, servletresponse response) throws exception {
        httpservletrequest httpservletrequest = (httpservletrequest) request;
        httpsession session = httpservletrequest.getsession();
        string kaptchacode = (string) session.getattribute(kaptcha);
        string code = httpservletrequest.getparameter("code");
        if(code!=null&&kaptchacode!=null&&!kaptchacode.equals(code)){
            httpservletrequest.setattribute("shirologinfailure","codeerror");
            return true;
        }
        return super.onaccessdenied(request, response);
    }
*/
    //用户提交表单时候  创建的token
    @override
    protected authenticationtoken createtoken( servletrequest request, servletresponse response) {
        httpservletrequest httpservletrequest = (httpservletrequest) request;
        string code = (string) httpservletrequest.getparameter("kaptcha");
        string host = gethost(request);
        string username = getusername(request);
        string password = getpassword(request);
        boolean rememberme = isrememberme(request);
        system.out.println("create token--------------code------>one "+code);
        return new usernamepasswordkaptchatoken(username,password.tochararray(),rememberme,host,code);
    }
}

自定义usernamepassword是为了接收前台发送过来的数据

package com.youxiong.shiro;

import org.apache.shiro.authc.authenticationtoken;
import org.apache.shiro.authc.usernamepasswordtoken;

import java.io.serializable;

public class usernamepasswordkaptchatoken extends usernamepasswordtoken {

    private static final long serialversionuid = 1l;

    private string kaptcha;


    public usernamepasswordkaptchatoken(){
        super();
    }

    public usernamepasswordkaptchatoken(string username, char[] password, boolean rememberme, string host, string kaptcha) {
        super(username, password, rememberme, host);
        this.kaptcha = kaptcha;
    }

    public string getkaptcha() {
        return kaptcha;
    }

    public void setkaptcha(string kaptcha) {
        this.kaptcha = kaptcha;
    }
}

    //这里就是会话管理的操作类
    @bean

    //这里需要设置一个cookie的名称  原因就是会跟原来的session的id值重复的

    public simplecookie simplecookie() {

shiro中的权限控制

#需要同时拥有order:add和order:query权限才可以访问
/order-add = perms["order:add","order:query"]
#只需要order:del权限就可以访问
/order-del = perms["order:del"]

perms表示的就是权限控制,中括号中就是需要访问等号之前路径,需要的权限名称。如果在使用shiro过滤器的时候,不配置过滤器,就会使用默认的过滤器。

以下是默认权限过滤器的源码。

public class permissionsauthorizationfilter extends authorizationfilter {
    public permissionsauthorizationfilter() {
    }

    public boolean isaccessallowed(servletrequest request, servletresponse response, object mappedvalue) throws ioexception {
        subject subject = this.getsubject(request, response);
        string[] perms = (string[])mappedvalue;
        boolean ispermitted = true;
        if (perms != null && perms.length > 0) {
            if (perms.length == 1) {
                if (!subject.ispermitted(perms[0])) {
                    ispermitted = false;
                }
            } else if (!subject.ispermittedall(perms)) {
                ispermitted = false;
            }
        }

        return ispermitted;
    }
}

从上面的代码可以看出,我们的配置会默认被强转为string类型的字符串数组。当只有一个权限时,会直接判断有没有该权限; 当配置多个权限时,从下面的代码可以看出只用在请求url的用户拥有所有的权限时,才会返回true,否则就会被拒绝访问。
