SpringBoot+SpringSecurity+RBAC+JWT实现动态权限框架

一、创建数据库表

status int(1) DEFAULT ‘1’ COMMENT ‘帐号启用状态：0->禁用；1->启用’,
PRIMARY KEY (id)
) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8 COMMENT=‘后台用户表’;
添加数据：

1.白名单配置

public class IgnoreUrlsConfig {
    private List urls = new ArrayList<>();

    public List getUrls() {
        return urls;
    }

    public void setUrls(List urls) {
        this.urls = urls;
    }
}
secure:
  ignored:
    urls: #安全路径白名单
      - *.html
      - *.js
      - *.css
      - *.png
      - /favicon.ico
      - /actuator
    public CorsConfigurationSource corsConfigurationSource() {

        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();

        CorsConfiguration configuration = new CorsConfiguration();

        configuration.setAllowCredentials(true);
        configuration.addAllowedHeader("*");
        configuration.setAllowedMethods(Collections.singletonList("*"));
        configuration.setAllowedOriginPatterns(Collections.singletonList("*"));
        configuration.setMaxAge(Duration.ofHours(1));
        source.registerCorsConfiguration("
@Component
public class DynamicAccessDecisionManager implements AccessDecisionManager {
    
    @Override

        // 当接口未被配置资源时直接放行
        if (CollUtil.isEmpty(configAttributes)){

            String needAuthority = configAttribute.getAttribute();

            }
