# 编写一个用户类 #

继承UserDetails类  
![在这里插入图片描述][20210114223014562.png]

@Entity
    public class User implements UserDetails { 
    
    
        /** * 编号 */
        @Id
        @GeneratedValue
        private Integer userId;
    
        /** * 用户名 */
        private String username;
    
        /** * 密码 */
        private String password;
    
        /** * 权限 */
        private String roles;
    
        /** * 验证码 * 未使用 */
        private Integer lastvcode;
    
        public Integer getUserId() { 
            return userId;
        }
    
        public void setUserId(Integer userId) {

        }
    
        @Override
        public boolean isCredentialsNonExpired() { 
            return true;
        }
    
        @Override
        public boolean isEnabled() { 
            return true;
        }
    
        public void setUsername(String username) { 
            this.username = username;
        }
    
        @Override
        public Collection<? extends GrantedAuthority> getAuthorities() { 
            return null;
        }
    
        @Override
        public String getPassword() { 
            return password;
        }
    
        @Override
        public String getUsername() { 
            return username;
        }
    
        public void setPassword(String password) { 
            this.password = password;
        }
    
        public Integer getLastvcode() { 
            return lastvcode;
        }
    
        public void setLastvcode(Integer lastvcode) { 
            this.lastvcode = lastvcode;
        }
    
        public String getRoles() { 
            return roles;
        }
    
        public void setRoles(String roles) { 
            this.roles = roles;
        }
    
        @Override
        public String toString() { 
            return "User{" +
                    "userId=" + userId +
                    ", username='" + username + '\'' +
                    '}';
        }
    
        @Override
        public boolean equals(Object o) { 
            if (this == o) return true;
            if (o == null || getClass() != o.getClass()) return false;
            User user = (User) o;
            return
                    Objects.equals(username, user.username) ;
        }
    
        @Override
        public int hashCode() { 
            return Objects.hash(username);
        }
    }

# 配置用户数据库操作 #

@Repository
    public interface UserRepository extends JpaRepository<User,Integer> { 
    
    
        Optional<User> findByUsername(String username);
    
    }

# 配置登陆时查询数据库操作 #

方便认证鉴权使用

@Service
    public class UserService implements UserDetailsService { 
    
    
        @Autowired
        UserRepository userRepository;
    
    // @Autowired
    // PasswordEncoder passwordEncoder;
    
    
    
        @Override
        public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException { 
    
            Optional<User> optionalUser = userRepository.findByUsername(username);
                User user;
                if (!optionalUser.isPresent()){ 
                    throw new UsernameNotFoundException("用户不存在");
                }
                user = optionalUser.get();
    
                List<GrantedAuthority> authorityList = new ArrayList<>();
                if (user.getRoles().equals("user")) { 
    
                    authorityList.add(new SimpleGrantedAuthority("ROLE_user"));
    
                }
    
                if (user.getRoles().equals("admin")) { 
    
                    authorityList.add(new SimpleGrantedAuthority("ROLE_admin"));
    
                }
    
    
    
                return new org.springframework.security.core.userdetails.User(
                        user.getUsername(),
                        user.getPassword(),
                        authorityList
                );
        }
    }

# 配置Security #

编写Security配置类 继承WebSecurityConfigurerAdapter  
CTRL加鼠标左键可以看源码  
![在这里插入图片描述][20210114223251317.png]

@Configuration
    public class SecurityConfig extends WebSecurityConfigurerAdapter { 
    
        @Autowired
        UserService userService;
    
        @Override
        @Bean
        protected AuthenticationManager authenticationManager() throws Exception { 
            return super.authenticationManager();
        }
    
        @Override
        @Bean
        protected UserDetailsService userDetailsService() { 
            return userService;
        }
    
        @Override
        protected void configure(AuthenticationManagerBuilder auth) throws Exception { 
            auth.userDetailsService(userDetailsService());
        }
    
        @Override
        protected void configure(HttpSecurity http) throws Exception { 
            http
                    .antMatcher("oauth/**")
                    .authorizeRequests()
                   .and()
                    .sessionManagement().maximumSessions(1)
                    .and()
                    .and()
                    .authorizeRequests()
                    .antMatchers("/oauth/**").permitAll()
                    .antMatchers("/logout").permitAll()
                    .and().cors().and().csrf().disable()
    
                    ;
        }
    }

# 配置资源管理类 #

说明  
系统一共配置两种权限  
管理员和普通用户  
管理员可以操作全部操作 普通用户只能查成绩啥的

@Configuration
    @EnableResourceServer
    public class ResourceServerConfig extends ResourceServerConfigurerAdapter { 
        @Override
        public void configure(ResourceServerSecurityConfigurer resources) throws Exception { 
            resources.resourceId("rid").stateless(true);
        }
    
    
    
        @Override
        public void configure(HttpSecurity http) throws Exception { 
    
            http
                    .authorizeRequests()
                    .antMatchers("/sign").permitAll()
                    .antMatchers("/logout").permitAll()
                    .antMatchers("/admin/**").hasAnyRole("admin")
                    .antMatchers("/user/**").hasAnyRole("user","admin")
                    .anyRequest().authenticated()
                    .and()
                    .cors();
        }
    }

# 配置鉴权 #

@Configuration
    @EnableAuthorizationServer
    public class AuthorizationSeverConfig extends AuthorizationServerConfigurerAdapter { 
    
    
        @Autowired
        AuthenticationManager authenticationManager;
    
    // @Autowired 如果使用redis请使用这个 并注释 DataSource
    // 且endpoints.tokenStore(new JdbcTokenStore(dataSource))替换为endpoints.tokenStore(new RedisTokenStore(redisConnectionFactory))
    // RedisConnectionFactory redisConnectionFactory;
    
        @Autowired
        UserDetailsService userService;
    
        @Autowired
        DataSource dataSource;
    
        @Bean
        PasswordEncoder passwordEncoder(){ 
            return new BCryptPasswordEncoder();//加密
        }
    
    
    
        @Override
        public void configure(ClientDetailsServiceConfigurer clients) throws Exception { 
            clients.inMemory()
                    .withClient("password")
                    .authorizedGrantTypes("password","refresh_token")//密码登陆认证
                    .accessTokenValiditySeconds(18000)//有效时间
                    .resourceIds("rid")//资源id看资源配置类
                    .scopes("all")
                    .secret(passwordEncoder().encode("123"));
    
        }
    
        @Override
        public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception { 
            endpoints.tokenStore(new JdbcTokenStore(dataSource))
                    .authenticationManager(authenticationManager)
                    .userDetailsService(userService);
        }
    
        @Override
        public void configure(AuthorizationServerSecurityConfigurer security) throws Exception { 
            security.tokenKeyAccess("permitAll()")
                    .checkTokenAccess("permitAll()")
                    .allowFormAuthenticationForClients();
        }
    }

# 建立数据库表 #

DROP TABLE IF EXISTS `oauth_access_token`;
    CREATE TABLE `oauth_access_token` (
      `create_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
      `token_id` varchar(255) DEFAULT NULL,
      `token` blob,
      `authentication_id` varchar(255) DEFAULT NULL,
      `user_name` varchar(255) DEFAULT NULL,
      `client_id` varchar(255) DEFAULT NULL,
      `authentication` blob,
      `refresh_token` varchar(255) DEFAULT NULL
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

DROP TABLE IF EXISTS `oauth_refresh_token`;
    CREATE TABLE `oauth_refresh_token` (
