shiro学习

shiro中的第一个程序用户认证

 //1.创建安全管理器对象
        DefaultSecurityManager securityManager=new DefaultSecurityManager();

        //2.给安全管理器设置realm
        securityManager.setRealm(new IniRealm("classpath:shiro.ini"));

        //3.SecurityUtils 给全局安全工具类设置安全管理器
        SecurityUtils.setSecurityManager(securityManager);

        //4.关键对象subject主体
        Subject subject=SecurityUtils.getSubject();

        //5.创建令牌
        UsernamePasswordToken   token=new UsernamePasswordToken("xiaoou","1123");
        try {
            subject.login(token);
            System.out.println("认证状态:"+subject.isAuthenticated());
        }catch (UnknownAccountException w){
            System.out.println("账号不存在!");
        }catch (IncorrectCredentialsException e){
            System.out.println("密码错误!");
        }finally {
            System.out.println("认证结束 ");
        }

shiro中认证流程源码

认证：1.最终执行用户名比较 是在SimpleAccountRealm类中的doGetAuthenticationInfo 方法中完成用户名校验的

    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        UsernamePasswordToken upToken = (UsernamePasswordToken) token;
        SimpleAccount account = getUser(upToken.getUsername());

        if (account != null) {

            if (account.isLocked()) {
                throw new LockedAccountException("Account [" + account + "] is locked.");
            }
            if (account.isCredentialsExpired()) {
                String msg = "The credentials for account [" + account + "] are expired";
                throw new ExpiredCredentialsException(msg);
            }

        }

        return account;
    }

2.最终密码校验是在AuthenticatingRealm类中的assertCredentialsMatch方法中完成密码校验的

protected void assertCredentialsMatch(AuthenticationToken token, AuthenticationInfo info) throws AuthenticationException {
    CredentialsMatcher cm = getCredentialsMatcher();
    if (cm != null) {
        if (!cm.doCredentialsMatch(token, info)) {
            //not successful - throw an exception to indicate this:
            String msg = "Submitted credentials for token [" + token + "] did not match the expected credentials.";
            throw new IncorrectCredentialsException(msg);
        }
    } else {
        throw new AuthenticationException("A CredentialsMatcher must be configured in order to verify " +
                "credentials during authentication.  If you do not wish for credentials to be examined, you " +
                "can configure an " + AllowAllCredentialsMatcher.class.getName() + " instance.");
    }
}

总结:

AuthenticatingRealm   认证realm          doGetAuthenticationInfo

AuthorizingRealm         授权realm         doGetAuthorizationInfo

shiro自定义Realm

测试类:

        //创建SecuirityManager
        DefaultSecurityManager defaultSecurityManager = new DefaultSecurityManager();
        //设置自定义realm
        defaultSecurityManager.setRealm(new CustomerRealm());
        //将安全工具类设置安全工具类
        SecurityUtils.setSecurityManager(defaultSecurityManager);
        //通过安全管理器获取Subject（主体）
        Subject subject = SecurityUtils.getSubject();
        //创建token
        UsernamePasswordToken usernamePasswordToken=new UsernamePasswordToken("x","6");
        try {
            subject.login(usernamePasswordToken);
            System.out.println("状态"+subject.isAuthenticated());

        }catch (UnknownAccountException e){
            System.out.println("账号错误");
        }catch (IncorrectCredentialsException e){
            System.out.println("密码错误");
        }

自定义的realm

package org.realm;

import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;

public class CustomerRealm extends AuthorizingRealm {


    //授权realm
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        //因为暂时还没有涉及到授权 所有授权可以忽略
        return null;
    }

    //认证realm
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        //在token中获取用户名
        Object principal = token.getPrincipal();
       //模拟使用mybatis查询数据库
        if (principal.toString().equals("x")){
            //参数一 返回数据库中正确的用户名  参数二返回数据库中的正确密码   参数三 提供当前realm的名字
            SimpleAuthenticationInfo simpleAuthenticationInfo = new SimpleAuthenticationInfo(principal.toString(),"6",this.getName());
            return simpleAuthenticationInfo;
        }
        return null;
    }
