什么是RBAC权限模型r

基于角色的权限访问控制（Role-Based Access Control）作为传统访问控制（自主访问，强制访问）的有前景的代替受到广泛的关注。在RBAC中，权限与角色相关联，用户通过成为适当角色的成员而得到这些角色的权限。这就极大地简化了权限的管理。在一个组织中，角色是为了完成各种工作而创造，用户则依据它的责任和资格来被指派相应的角色，用户可以很容易地从一个角色被指派到另一个角色。角色可依新的需求和系统的合并而赋予新的权限，而权限也可根据需要而从某角色中回收。角色与角色的关系可以建立起来以囊括更广泛的客观情况。

微服务系统中，管理平台也是有分布式的，比如会员管理，订单管理，支付管理等

最终通过SSO将公司颞部所有管理进行整合。比如用户同一登录 www.toov5.com 进行管理

将权限的设置信息不要写死通过表去进行动态的配置动态的维护整合Mybatis就OK了

通过表的动态配置

参考前面的写死的配置

数据库环境：

对密码需要加密 md5加密

对传入到后台的数据进行比对：

对于加密后的处理逻辑：

用户登录时候会去各个表中查询出信息

包括权限信息

通过查询出来的信息给配置文件赋值，动态赋值。

管理者可以通过管理这些表去进行权限的管理。

对于User的bean字段需要严格按照规范去写，框架已经定义了接口，需要去实现：

// 用户信息表
@Data
public class User implements UserDetails {
   //框架地层查询时候 必须依赖的字段 实现这个接口 规范了名称
    private Integer id;
    private String username;
    private String realname;
    private String password;
    private Date createDate;
    private Date lastLoginTime;
    private boolean enabled;
    private boolean accountNonExpired;
    private boolean accountNonLocked;
    private boolean credentialsNonExpired;
    // 用户所有权限
    private List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();

    public Collection<? extends GrantedAuthority> getAuthorities() {  //一个用户可能多个权限 所以用了集合去处理存储
        return authorities;
    }

}

对于数据库的查询:Mapper层

import java.util.List;

import org.apache.ibatis.annotations.Select;

import com.mayikt.entity.Permission;

public interface PermissionMapper {

    // 查询苏所有权限
    @Select(" select * from sys_permission ")
    List<Permission> findAllPermission();

}

import java.util.List;

import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;

import com.mayikt.entity.Permission;
import com.mayikt.entity.User;

public interface UserMapper {
    // 查询用户信息
    @Select(" select * from sys_user where username = #{userName}")
    User findByUsername(@Param("userName") String userName);

    // 查询用户的权限
    @Select(" select permission.* from sys_user user" + " inner join sys_user_role user_role"
            + " on user.id = user_role.user_id inner join "
            + "sys_role_permission role_permission on user_role.role_id = role_permission.role_id "
            + " inner join sys_permission permission on role_permission.perm_id = permission.id where user.username = #{userName};")
    List<Permission> findPermissionByUsername(@Param("userName") String userName);
}

登录时候会首先执行的Java类：

先查询出User信息

使用UserDetailsService实现动态查询数据库验证账号

import java.util.ArrayList;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
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.mayikt.entity.Permission;
import com.mayikt.entity.User;
import com.mayikt.mapper.UserMapper;

// 设置动态用户信息
@Service
public class MyUserDetailsService implements UserDetailsService {
    @Autowired
    private UserMapper userMapper;

    @Override   //用户登录时候会调用这个方法 
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {

        // 1.根据用户名称查询数据用户信息
        User user = userMapper.findByUsername(username);
        // 2.底层会根据数据库查询用户信息，判断密码是否正确   开发者需要做的就是查询就OK了
        // 3. 给用户设置权限     查询出来 然后赋值就OK了
        List<Permission> listPermission = userMapper.findPermissionByUsername(username);
        System.out.println("username:" + username + ",对应权限:" + listPermission.toString());
        if (listPermission != null && listPermission.size() > 0) {
            // 定义用户权限
            List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
            for (Permission permission : listPermission) {
                authorities.add(new SimpleGrantedAuthority(permission.getPermTag()));
            }
            user.setAuthorities(authorities);
        }
        return user;
    }

}

进行权限的校验设置：

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.annotation.web.configurers.ExpressionUrlAuthorizationConfigurer;
import org.springframework.security.crypto.password.NoOpPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Component;

import com.mayikt.entity.Permission;
import com.mayikt.handler.MyAuthenticationFailureHandler;
import com.mayikt.handler.MyAuthenticationSuccessHandler;
import com.mayikt.mapper.PermissionMapper;
import com.mayikt.security.MyUserDetailsService;
import com.mayikt.utils.MD5Util;

// Security 配置
@Component
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private MyAuthenticationFailureHandler failureHandler;
    @Autowired
    private MyAuthenticationSuccessHandler successHandler;
    @Autowired
    private MyUserDetailsService myUserDetailsService;
    @Autowired
    private PermissionMapper permissionMapper;

    // 配置认证用户信息和权限
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        // // 添加admin账号
        // auth.inMemoryAuthentication().withUser("admin").password("123456").
        // authorities("showOrder","addOrder","updateOrder","deleteOrder");
        // // 添加userAdd账号
        // auth.inMemoryAuthentication().withUser("userAdd").password("123456").authorities("showOrder","addOrder");
        // 如果想实现动态账号与数据库关联 在该地方改为查询数据库
        auth.userDetailsService(myUserDetailsService).passwordEncoder(new PasswordEncoder() {

            // 加密的密码与数据库密码进行比对CharSequence rawPassword 表单字段 encodedPassword
            // 数据库加密字段
            public boolean matches(CharSequence rawPassword, String encodedPassword) {
                System.out.println("rawPassword:" + rawPassword + ",encodedPassword:" + encodedPassword);
                // 返回true 表示认证成功 返回fasle 认证失败
                Boolean reslt = MD5Util.encode((String) rawPassword).equals(encodedPassword);
                System.out.println("result结果："+reslt);
                return reslt;
            }

            // 对表单密码进行加密
            public String encode(CharSequence rawPassword) {
                System.out.println("rawPassword:" + rawPassword);
                return MD5Util.encode((String) rawPassword);
            }
        });
    }

    // 配置拦截请求资源    进行动态请求资源
    protected void configure(HttpSecurity http) throws Exception {
        ExpressionUrlAuthorizationConfigurer<HttpSecurity>.ExpressionInterceptUrlRegistry authorizeRequests = http
                .authorizeRequests();
        // 1.读取数据库权限列表
        List<Permission> listPermission = permissionMapper.findAllPermission();
        for (Permission permission : listPermission) {
            // 设置权限
            authorizeRequests.antMatchers(permission.getUrl()).hasAnyAuthority(permission.getPermTag());
        }
        authorizeRequests.antMatchers("/login").permitAll().antMatchers("/**").fullyAuthenticated().and().formLogin()
                .loginPage("/login").successHandler(successHandler).and().csrf().disable();

    }

    @Bean
    public static NoOpPasswordEncoder passwordEncoder() {
        return (NoOpPasswordEncoder) NoOpPasswordEncoder.getInstance();
    }

}

    private static final String SALT = "toov5";

    public static String encode(String password) {
        password = password + SALT;
        MessageDigest md5 = null;
        try {
            md5 = MessageDigest.getInstance("MD5");
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
        char[] charArray = password.toCharArray();
        byte[] byteArray = new byte[charArray.length];

        for (int i = 0; i < charArray.length; i++)
            byteArray[i] = (byte) charArray[i];
        byte[] md5Bytes = md5.digest(byteArray);
        StringBuffer hexValue = new StringBuffer();
        for (int i = 0; i < md5Bytes.length; i++) {
            int val = ((int) md5Bytes[i]) & 0xff;
            if (val < 16) {
                hexValue.append("0");
            }

            hexValue.append(Integer.toHexString(val));
        }
        return hexValue.toString();
    }

    public static void main(String[] args) {
        System.out.println(MD5Util.encode("123456"));

    }
}

启动类：

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@MapperScan("com.toov5.mapper")
@SpringBootApplication
public class AppSecurity {

    public static void main(String[] args) {
        SpringApplication.run(AppSecurity.class, args);
        // Security 两种模式 fromLogin 表单提交认证模式 httpBasic 浏览器与服务器做认证授权
    }

}

这样就成为了根据SQL进行动态配置修改的啦~~
