swagger-ui.html报错404

问题1：权限受限无法访问

由于采用的Shiro安全框架，需要在配置类ShiroConfig下的Shiro 的过滤器链放行该页面：【添加：filterChainDefinitionMap.put("/swagger-ui.html", "anon");】

public ShiroFilterFactoryBean shiroFilterFactoryBean(SecurityManager securityManager) {

        //整个shiro执行过程： 过滤器、认证、授权

        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        //设置安全管理器
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        LinkedHashMap<String, Filter> filtersMap = new LinkedHashMap<>();
        //用来校验token
        filtersMap.put("token", new CustomAccessControlFilter());
        shiroFilterFactoryBean.setFilters(filtersMap);
        Map<String, String> filterChainDefinitionMap = new LinkedHashMap<>();
        // 配置不会被拦截的链接 顺序判断
filterChainDefinitionMap.put("/swagger-ui.html", "anon");
        
        shiroFilterFactoryBean.setLoginUrl("/login_page");

        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
        return shiroFilterFactoryBean;
    }

问题2：报错

Whitelabel Error Page This application has no explicit mapping for /error, so you are seeing this as a fallback

在WebInterceptorConfig类中定义注册的资源处理器对外暴露资源.

public class WebInterceptorConfig extends WebMvcConfigurationSupport {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/**").addResourceLocations(
                "classpath:/static/");
        registry.addResourceHandler("doc.html").addResourceLocations(
                "classpath:/META-INF/resources/");
        registry.addResourceHandler("/swagger-ui.html").addResourceLocations(
                "classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**").addResourceLocations(
                "classpath:/META-INF/resources/webjars/");
    }
}
