Spring Boot 鉴权之—— springboot2.0.4+mybatis 整合的完整用例

自上一篇文章的基础上，Spring Boot 鉴权之—— JWT 鉴权我做了一波springboot2.0.4+mybatis 的整合。

参考文章： Spring Boot+Spring Security+JWT 实现 RESTful Api 权限控制

源码地址：

码云：https://gitee.com/region/spring-security-oauth-example/tree/master/spring-security-jwt

springboot2.0.4+mybatis pom.xml:

这里由于springboot2.0.4没有默认的passwordencoder，也就是说我们登录不能明文登录，所以为了方便期间，我直接使用了数据库。

@Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Qualifier("userDetailServiceImpl")
    @Autowired
    private UserDetailsService userDetailsService;

    @Autowired
    private BCryptPasswordEncoder bCryptPasswordEncoder;

    @Override
    public void configure(WebSecurity web) throws Exception {
        super.configure(web);
    }

    @Override

        // 使用自定义身份验证组件   手动注入加密类
        auth.authenticationProvider(new CustomAuthenticationProvider(userDetailsService, bCryptPasswordEncoder));
    }

}

自定义身份验证组件

package com.jwt.server.provider;

import java.util.ArrayList;

import org.springframework.security.authentication.AuthenticationProvider;
import org.springframework.security.authentication.BadCredentialsException;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;


/**
 * 自定义身份认证验证组件
 * @author zyl
 *
 */
public class CustomAuthenticationProvider implements AuthenticationProvider {

    private UserDetailsService userDetailsService;

    private BCryptPasswordEncoder bCryptPasswordEncoder;

    public CustomAuthenticationProvider(UserDetailsService userDetailsService, BCryptPasswordEncoder bCryptPasswordEncoder){
        this.userDetailsService = userDetailsService;
        this.bCryptPasswordEncoder = bCryptPasswordEncoder;
    }

    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
        // 获取认证的用户名 & 密码
        String name = authentication.getName();
        String password = authentication.getCredentials().toString();
        // 认证逻辑
        UserDetails userDetails = userDetailsService.loadUserByUsername(name);
        if (null != userDetails) {
            if (bCryptPasswordEncoder.matches(password, userDetails.getPassword())) {
                // 这里设置权限和角色
                ArrayList<GrantedAuthority> authorities = new ArrayList<>();
                authorities.add( new GrantedAuthorityImpl("ROLE_ADMIN"));
                authorities.add( new GrantedAuthorityImpl("ROLE_API"));
                authorities.add( new GrantedAuthorityImpl("AUTH_WRITE"));
                // 生成令牌 这里令牌里面存入了:name,password,authorities, 当然你也可以放其他内容
                Authentication auth = new UsernamePasswordAuthenticationToken(name, password, authorities);
                return auth;
            } else {
                throw new BadCredentialsException("密码错误");
            }
        } else {
            throw new UsernameNotFoundException("用户不存在");
        }
    }

    /**
     * 是否可以提供输入类型的认证服务
     * @param authentication
     * @return
     */
    @Override
    public boolean supports(Class<?> authentication) {
        return authentication.equals(UsernamePasswordAuthenticationToken.class);
    }

}

权限类型，负责存储权限和角色

package com.jwt.server.provider;

import org.springframework.security.core.GrantedAuthority;

/**
 * 权限类型，负责存储权限和角色
 *
 * @author zyl
 */
public class GrantedAuthorityImpl implements GrantedAuthority {

    /**
     * 
     */
    private static final long serialVersionUID = 1L;
    
    private String authority;

    public GrantedAuthorityImpl(String authority) {
        this.authority = authority;
    }

    public void setAuthority(String authority) {
        this.authority = authority;
    }

    @Override
    public String getAuthority() {
        return this.authority;
    }
}

定义数据库service、dao文件

package com.jwt.server.service;

import com.jwt.server.domain.UserInfo;

/**
 * 用户service
 * @author zyl
 *
 */
public interface UserService {

    /**
     * 根据用户名查询用户是否存在
     * @param username
     * @return
     */
    public UserInfo findByUsername(String username);

    /**
     * 添加用户
     * @param user
     * @return
     */
    public UserInfo save(UserInfo user);

}

package com.jwt.server.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.jwt.server.domain.UserInfo;
import com.jwt.server.mapper.UserMapper;
import com.jwt.server.service.UserService;

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserMapper  usermapper;
    
    @Override
    public UserInfo findByUsername(String username) {
        return usermapper.findByUsername(username);
    }

    @Override
    public UserInfo save(UserInfo user) {
        return usermapper.save(user);
    }

}

修改之前定义的UserDetailServiceImpl文件为：

package com.jwt.server.service.impl;

import static java.util.Collections.emptyList;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;

import com.jwt.server.domain.UserInfo;
import com.jwt.server.service.UserService;

/**
 * 
 * @author zyl
 *
 */
@Service
public class UserDetailServiceImpl implements UserDetailsService {

    @Autowired
    protected UserService userService;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        UserInfo user = userService.findByUsername(username);
        if (user == null) {
            throw new UsernameNotFoundException(username);
        }
        return new org.springframework.security.core.userdetails.User(user.getUsername(), user.getPassword(),
                emptyList());
    }
}

增加IdGenerator id生成类

package com.jwt.server.util;


import java.net.InetAddress;
import java.net.UnknownHostException;

import org.apache.commons.lang3.time.DateFormatUtils;

import lombok.extern.slf4j.Slf4j;

/**
 * 与snowflake算法区别,返回字符串id,占用更多字节,但直观从id中看出生成时间
 *
 */
@Slf4j
public enum IdGenerator {
    /**
     * 每个要生成的序号类型对应一个序号
     */
    USER_TRANSID("1");

    private long workerId;   //用ip地址最后几个字节标示
    private long datacenterId = 0L; //可配置在properties中,启动时加载,此处默认先写成0
    private long sequence = 0L;
    private final long twepoch = 1516175710371L;
    private final long workerIdBits = 1L;
    private final long datacenterIdBits = 2L;
    private final long sequenceBits = 3L;
    private final long workerIdShift = sequenceBits;
    private final long datacenterIdShift = sequenceBits + workerIdBits;
    private final long timestampLeftShift = sequenceBits + workerIdBits + datacenterIdBits;
    private long sequenceMask = -1L ^ (-1L << sequenceBits); //4095
    private long lastTimestamp = -1L;

    private String index;
    
    IdGenerator(String ind) {
        this.index = ind;
        workerId = 0x000000FF & getLastIP();
    }

    public synchronized String nextId() {
        long timestamp = timeGen(); //获取当前毫秒数
        //如果服务器时间有问题(时钟后退) 报错。
        if (timestamp < lastTimestamp) {
            throw new RuntimeException(String.format(
                    "Clock moved backwards.  Refusing to generate id for %d milliseconds", lastTimestamp - timestamp));
        }
        //如果上次生成时间和当前时间相同,在同一毫秒内
        if (lastTimestamp == timestamp) {
            //sequence自增，因为sequence只有12bit，所以和sequenceMask相与一下，去掉高位
            sequence = (sequence + 1) & sequenceMask;
            //判断是否溢出,也就是每毫秒内超过4095，当为4096时，与sequenceMask相与，sequence就等于0
            if (sequence == 0) {
                timestamp = tilNextMillis(lastTimestamp); //自旋等待到下一毫秒
            }
        } else {
            sequence = 0L; //如果和上次生成时间不同,重置sequence，就是下一毫秒开始，sequence计数重新从0开始累加
        }
        lastTimestamp = timestamp;

        long suffix =  ((timestamp - twepoch) << timestampLeftShift) | (datacenterId << datacenterIdShift) | (workerId << workerIdShift) | sequence;
        
        String datePrefix = DateFormatUtils.format(timeGen(), "yyyyMMddHHmmss");
        return datePrefix +index + suffix;
    }
    

    private long tilNextMillis(long lastTimestamp) {
        long timestamp = timeGen();
        while (timestamp <= lastTimestamp) {
            timestamp = timeGen();
        }
        return timestamp;
    }

    private long timeGen() {
        return System.currentTimeMillis();
    }

    private byte getLastIP(){
        byte lastip = 0;
        try{
            InetAddress ip = InetAddress.getLocalHost();
            byte[] ipByte = ip.getAddress();
            lastip = ipByte[ipByte.length - 1];
        } catch (UnknownHostException e) {
            log.error("UnknownHostException error：{}", e.getMessage());
        }
        return lastip;
    }
    
    public static void main(String[] args) {
        IdGenerator id = IdGenerator.USER_TRANSID;
        for (int i = 0; i < 1000; i++) {
            String serialNo = id.nextId();
            System.out.println(serialNo + "===" + serialNo.length());
