springcloudsecurity+oauth+redis（jdbc）+mybatisplus实现授权认证+资源认证（基于授权码模式）

springcloudsecurity+oauth+redis+mybatisplus实现授权认证（基于授权码模式）
理解OAuth 2.0：http://www.ruanyifeng.com/blog/2014/05/oauth_2_0.html
1.技术栈；springboot+springcloudsecurity+mybatisplus

交互过程

oAuth 在 “客户端” 与 “服务提供商” 之间，设置了一个授权层（authorization layer）。“客户端” 不能直接登录 “服务提供商”，只能登录授权层，以此将用户与客户端区分开来。“客户端” 登录授权层所用的令牌（token），与用户的密码不同。用户可以在登录的时候，指定授权层令牌的权限范围和有效期。“客户端” 登录授权层以后，“服务提供商” 根据令牌的权限范围和有效期，向 “客户端” 开放用户储存的资料

认证服务器

1.AuthorizationServerConfiguration.java

@Configuration
@EnableAuthorizationServer

        // 设置令牌
        endpoints

        oauthServer.allowFormAuthenticationForClients();

        oauthServer.checkTokenAccess("permitAll()");
    }

2.WebSecurityConfiguration.java


@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true, jsr250Enabled = true)//全局方法拦截
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Autowired
    private UserDetailsServiceImpl userDetailsService;

        auth

            .userDetailsService(userDetailsService())
            .passwordEncoder(passwordEncoder());
    }
    @Override
    public void configure(WebSecurity web) throws Exception {
        // 将 check_token 暴露出去，否则资源服务器访问时报 403 错误
        web.ignoring().antMatchers("/oauth/check_token");
    }


    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {

        http.csrf().disable();
        http
            .requestMatchers().antMatchers("/oauth/**","/login/**","/logout/**")
            .and()
            .authorizeRequests()
            .antMatchers("/oauth/**").authenticated()
            .and()
            .formLogin().permitAll(); //新增login form支持用户登录及授权
    }
}

3.UserDetailsServiceImpl.java

@Service
public class UserDetailsServiceImpl implements UserDetailsService {

    @Autowired
    private TbPermissionService tbPermissionService;
    @Autowired

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        TbUser tbUser = tbUserService.queryTbUserByUserName(username);
        List<GrantedAuthority> grantedAuthorities = new ArrayList();
        if (StringUtils.isEmpty(tbUser)) {
            throw new UsernameNotFoundException("很抱歉，找不到用户名为" + username + "的用户！");
        }

        if (tbUser != null) {
            List<TbPermission> tbPermissions = tbPermissionService
                .queryPermissionByUserId(tbUser.getId());
            tbPermissions.forEach(tbPermission -> {
                if (tbPermission != null && tbPermission.getEnname() != null) {
                    GrantedAuthority grantedAuthority = new SimpleGrantedAuthority(tbPermission.getEnname());
                    grantedAuthorities.add(grantedAuthority);
                }
            });
        }
        /**
         * 若只是认证，要去掉grantedAuthorities换成 Collections.emptyList()
         * 若是要授权，要加上
         */
        CustomUserPrincipal userDetail = new CustomUserPrincipal(tbUser.getUsername(), tbUser.getPassword(), grantedAuthorities);
        userDetail.setTbUser(tbUser);
        return userDetail;
    }

资源服务器

4.ResourceServerConfiguration.java

@Configuration
@EnableResourceServer
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true, jsr250Enabled = true)
public class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {


    @Autowired
    private RedisConnectionFactory redisConnectionFactory;


    /*@Autowired
    private DataSource dataSource;
     @Bean
      public TokenStore tokenStore() {
        return new JdbcTokenStore(dataSource);
      }*/
    //
    @Bean
    public TokenStore tokenStore() {
        return new RedisTokenStore(redisConnectionFactory);
    }

    @Override
    public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
        //resourceId 推荐每个 受保护的资源都提供一下 ，可以供 auth服务对资源进行一个认证
        resources.resourceId("ls_resource").tokenStore(tokenStore());
    }

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http
            .exceptionHandling()
            .and()
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
            .and()
            .authorizeRequests()
            // 以下为配置所需保护的资源路径及权限，需要与认证服务器配置的授权部分对应
            .antMatchers("/contents").hasAuthority("SystemContent")
            .antMatchers("/view/**").hasAuthority("SystemContentView")
            .antMatchers("/insert/**").hasAuthority("SystemContentInsert")
            .antMatchers("/update/**").hasAuthority("SystemContentUpdate")
            .antMatchers("/delete/**").hasAuthority("SystemContentDelete");
