SpringBoot+shiro+JwtToken，多方式登录

其他 2019-08-15 00:18:06 阅读次数: 0

使用场景：用户使用手机号或密码登录后返回token，之后的请求的请求头带上token进行token鉴权。

 一、依赖

        <!-- aop -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-aop</artifactId>
        </dependency>    

        <!-- JWT -->
        <dependency>
            <groupId>com.auth0</groupId>
            <artifactId>java-jwt</artifactId>
            <version>3.4.0</version>
        </dependency>  
        
        <!-- shiro -->
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>

        securityManager.setSubjectDAO(subjectDAO);

        return securityManager;
    }

}

三、shiro多方式鉴权需要配置多个realm

　　1.验证码登录Realm

package com.ydzl.lxyd.config.realm;

import com.baomidou.mybatisplus.mapper.EntityWrapper;
import com.ydzl.lxyd.config.token.CustomizedToken;
import com.ydzl.lxyd.pojo.user.User;
import com.ydzl.lxyd.service.user.UserService;
import com.ydzl.lxyd.util.JwtUtil;
import com.ydzl.lxyd.util.RedisUtil;
import lombok.extern.slf4j.Slf4j;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.util.ByteSource;

import javax.annotation.Resource;

/**
 * @author lixiao
 * @date 2019/7/31 11:40
 */
@Slf4j
public class CodeRealm extends AuthorizingRealm {

    @Resource
    private UserService userService;

    @Resource
    private RedisUtil redisUtil;

    @Override
    public boolean supports(AuthenticationToken token) {
        return token instanceof CustomizedToken;
    }

    /**
     * 获取授权信息
     * @param principals principals
     * @return AuthorizationInfo
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        return null;
    }

    /**
     * 获取身份认证信息
     * @param authenticationToken authenticationToken
     * @return AuthenticationInfo
     * @throws AuthenticationException AuthenticationException
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {

        CustomizedToken token = (CustomizedToken) authenticationToken;
        log.info("CodeRealm"+token.getUsername()+"开始身份认证");
        // 根据手机号查询用户
        User user = userService.selectOne(new EntityWrapper<User>().eq("phone", token.getUsername()));
        if (user == null) {
            // 抛出账号不存在异常
            throw new UnknownAccountException();
        }
        // 1.principal：认证的实体信息，可以是手机号，也可以是数据表对应的用户的实体类对象
        // 2.从redis中获取登录验证码
        Object credentials = redisUtil.get(user.getPhone()+"loginCode");
        // 3.realmName：当前realm对象的name，调用父类的getName()方法即可

        // 4.盐,取用户信息中唯一的字段来生成盐值，避免由于两个用户原始密码相同，加密后的密码也相同
        ByteSource credentialsSalt = ByteSource.Util.bytes(user.getPhone());

        return new SimpleAuthenticationInfo(user, credentials, credentialsSalt, getName());
    }
}

　　2.密码登录Realm

package com.ydzl.lxyd.config.realm;

import com.baomidou.mybatisplus.mapper.EntityWrapper;
import com.ydzl.lxyd.config.token.CustomizedToken;
import com.ydzl.lxyd.pojo.user.User;
import com.ydzl.lxyd.service.user.UserService;
import com.ydzl.lxyd.util.JwtUtil;
import lombok.extern.slf4j.Slf4j;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.subject.Subject;
import org.apache.shiro.util.ByteSource;

import javax.annotation.Resource;

/**
 * @author lixiao
 * @date 2019/7/31 11:40
 */
@Slf4j
public class PasswordRealm extends AuthorizingRealm {

    @Resource
    private UserService userService;

    @Override
    public boolean supports(AuthenticationToken token) {
        return token instanceof CustomizedToken;
    }

    /**
     * 获取授权信息
     * @param principals principals
     * @return AuthorizationInfo
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        return null;
    }

    /**
     * 获取身份认证信息
     * @param authenticationToken authenticationToken
     * @return AuthenticationInfo
     * @throws AuthenticationException AuthenticationException
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {

        CustomizedToken token = (CustomizedToken) authenticationToken;
        log.info("PasswordRealm"+ token.getUsername()+ "开始身份认证");
        // 根据手机号查询用户
        User user = userService.selectOne(new EntityWrapper<User>().eq("phone", token.getUsername()));
        if (user == null) {
            // 抛出账号不存在异常
            throw new UnknownAccountException();
        }
        // 1.principal：认证的实体信息，可以是手机号，也可以是数据表对应的用户的实体类对象
        // 2.credentials：密码
        Object credentials = user.getPassword();
        // 3.realmName：当前realm对象的name，调用父类的getName()方法即可

        // 4.盐,取用户信息中唯一的字段来生成盐值，避免由于两个用户原始密码相同，加密后的密码也相同
        ByteSource credentialsSalt = ByteSource.Util.bytes(user.getPhone());
        return new SimpleAuthenticationInfo(user, credentials, credentialsSalt, getName());
    }
}

　　3.JwtTokenRealm

package com.ydzl.lxyd.config.realm;

import com.baomidou.mybatisplus.mapper.EntityWrapper;
import com.ydzl.lxyd.config.token.JwtToken;
import com.ydzl.lxyd.enums.ResultEnums;
import com.ydzl.lxyd.pojo.user.User;
import com.ydzl.lxyd.service.user.UserService;
import com.ydzl.lxyd.util.JwtUtil;
import lombok.extern.slf4j.Slf4j;
import org.apache.shiro.authc.AuthenticationException;
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.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;

import javax.annotation.Resource;

/**
 * @author lixiao
 * @date 2019/8/6 10:02
 */
@Slf4j
public class JwtRealm extends AuthorizingRealm {

    @Resource
    private UserService userService;

    @Override
    public boolean supports(AuthenticationToken token) {
        return token instanceof JwtToken;
    }

    /**
     * 只有当需要检测用户权限的时候才会调用此方法，例如checkRole,checkPermission之类的
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        log.info("JwtRealm  doGetAuthorizationInfo  运行()");
        String username = JwtUtil.getPhone(principals.toString());
        User user = userService.selectOne(new EntityWrapper<User>().eq("phone", username));

        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        authorizationInfo.addRole(user.getLastLoginIdentity()==0?"user":"driver");
        return authorizationInfo;

    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken auth) throws AuthenticationException {
        String token = (String) auth.getCredentials();
        // 解密获得username，用于和数据库进行对比
        String username = JwtUtil.getPhone(token);
        if (username == null) {
            throw new AuthenticationException(ResultEnums.TOKEN_INVALID.getMsg());
        }
        User user = userService.selectOne(new EntityWrapper<User>().eq("phone", username));
        if(user == null){
            throw new AuthenticationException(ResultEnums.USER_NOT_EXIST.getMsg());
        }
        if (!JwtUtil.verify(token, username, user.getUserId(), user.getPassword())) {
            throw new AuthenticationException(ResultEnums.TOKEN_ERROR.getMsg());
        }
        return new SimpleAuthenticationInfo(token, token, "JwtRealm");
    }
}

　　4.当配置了多个Realm时，我们通常使用的认证器是shiro自带的 org.apache.shiro.authc.pam.ModularRealmAuthenticator， 其中决定使用的Realm的是doAuthenticate()方法

package com.ydzl.lxyd.config.realm;

import com.ydzl.lxyd.config.token.CustomizedToken;
import com.ydzl.lxyd.config.token.JwtToken;
import lombok.extern.slf4j.Slf4j;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.pam.ModularRealmAuthenticator;
import org.apache.shiro.realm.Realm;

import java.util.ArrayList;
import java.util.Collection;

/**
 * @author lixiao
 * @date 2019/7/31 20:48
 *  当配置了多个Realm时，我们通常使用的认证器是shiro自带的
 *  org.apache.shiro.authc.pam.ModularRealmAuthenticator，
 *  其中决定使用的Realm的是doAuthenticate()方法
 */
@Slf4j
public class UserModularRealmAuthenticator extends ModularRealmAuthenticator {

    @Override
    protected AuthenticationInfo doAuthenticate(AuthenticationToken authenticationToken) throws AuthenticationException {
        log.info("UserModularRealmAuthenticator:method doAuthenticate() 执行 ");
        // 判断getRealms()是否返回为空
        assertRealmsConfigured();

        // 所有Realm
        Collection<Realm> realms = getRealms();
        // 登录类型对应的所有Realm
        Collection<Realm> typeRealms = new ArrayList<>();

        // 强制转换回自定义的Token
        try{
            JwtToken jwtToken = (JwtToken) authenticationToken;
            for(Realm realm : realms){
                if (realm.getName().contains("Jwt")){
                    typeRealms.add(realm);
                }
            }
            return doSingleRealmAuthentication(typeRealms.iterator().next(), jwtToken);
        }catch (ClassCastException e){
            typeRealms.clear();

            CustomizedToken customizedToken = (CustomizedToken) authenticationToken;
            // 登录类型
            String loginType = customizedToken.getLoginType();

            for (Realm realm : realms) {
                if (realm.getName().contains(loginType)){
                    typeRealms.add(realm);
                }
            }

            // 判断是单Realm还是多Realm
            if(typeRealms.size() == 1){
                return doSingleRealmAuthentication(typeRealms.iterator().next(), customizedToken);
            }else {
                return doMultiRealmAuthentication(typeRealms, customizedToken);
            }
        }

    }
}

四、其中用到了JWTUtils / 自定义TOKEN

package com.ydzl.lxyd.util;

import com.auth0.jwt.JWT;
import com.auth0.jwt.JWTVerifier;
import com.auth0.jwt.algorithms.Algorithm;
import com.auth0.jwt.exceptions.JWTDecodeException;
import com.auth0.jwt.exceptions.JWTVerificationException;
import com.auth0.jwt.interfaces.DecodedJWT;
import com.ydzl.lxyd.commons.Constant;

import java.util.Date;

/**
 * @author lixiao
 * @date 2019/8/5 23:46
 */
public class JwtUtil {


    /**
     * 校验token是否正确
     *
     * @param token  密钥
     * @param secret 用户的密码
     * @return 是否正确
     */
    public static boolean verify(String token, String phone, Integer userId, String secret) {
        try {
            //根据密码生成JWT效验器
            Algorithm algorithm = Algorithm.HMAC256(secret);
            JWTVerifier verifier = JWT.require(algorithm)
                    .withClaim("phone", phone)
                    .withClaim("userId", String.valueOf(userId))
                    .build();
            // 效验TOKEN
            verifier.verify(token);
            return true;
        } catch (JWTVerificationException exception) {
            return false;
        }
    }

    /**
     * 获得token中的信息无需secret解密也能获得
     *
     * @return token中包含的用户名
     */
    public static String getPhone(String token) {
        try {
            DecodedJWT jwt = JWT.decode(token);
            return jwt.getClaim("phone").asString();
        } catch (JWTDecodeException e) {
            return null;
        }
    }

    /**
     * 获得token中的信息无需secret解密也能获得
     *
     * @return token中包含的用户名
     */
    public static String getUserId(String token) {
        try {
            DecodedJWT jwt = JWT.decode(token);
            return jwt.getClaim("userId").asString();
        } catch (JWTDecodeException e) {
            return null;
        }
    }

    /**
     *
     * @param phone 用户名/手机号
     * @param userId   用户id
     * @param secret   用户的密码
     * @return 加密的token
     */
    public static String sign(String phone,Integer userId, String secret) {
        Date date = new Date(System.currentTimeMillis() + Constant.TOKEN_EXPIRE_TIME);
        Algorithm algorithm = Algorithm.HMAC256(secret);
        return JWT.create()
                .withClaim("phone", phone)
                .withClaim("userId", String.valueOf(userId))
                .withExpiresAt(date)
                .sign(algorithm);

    }

}
package com.ydzl.lxyd.config.token;

import org.apache.shiro.authc.UsernamePasswordToken;

/**
 * @author lixiao
 * @date 2019/7/31 20:54
 */
public class CustomizedToken extends UsernamePasswordToken {

    /**
     * 登录类型
     */
    private String loginType;

    public CustomizedToken(final String username, final String password, String loginType){
        super(username, password);
        this.loginType = loginType;
    }

    public String getLoginType() {
        return loginType;
    }

    public void setLoginType(String loginType) {
        this.loginType = loginType;
    }

    @Override
    public String toString(){
        return "loginType="+ loginType +",username=" + super.getUsername()+",password="+ String.valueOf(super.getPassword());
    }
}
package com.ydzl.lxyd.config.token;

import org.apache.shiro.authc.AuthenticationToken;

/**
 * @author lixiao
 * @date 2019/8/5 23:43
 */
public class JwtToken implements AuthenticationToken {

    private String token;

    public JwtToken(String token) {
        this.token = token;
    }

    @Override
    public Object getPrincipal() {
        return token;
    }

    @Override
    public Object getCredentials() {
        return token;
    }
}

六、自定义filter拦截自定义请求头拦截 / 获取token后进行鉴权

package com.ydzl.lxyd.filter;

import com.ydzl.lxyd.commons.Constant;
import com.ydzl.lxyd.config.token.JwtToken;

import com.ydzl.lxyd.enums.ResultEnums;
import lombok.extern.slf4j.Slf4j;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.web.filter.authc.BasicHttpAuthenticationFilter;
import org.springframework.http.HttpStatus;
