    private ApiInfo buildApiInfo() {
        Contact contact = new Contact("开发者","","");
        return new ApiInfoBuilder()
                .title("闪聚支付‐商户应用API文档")
                .description("") .contact(contact)

}


 

最后发现问题是浏览器上，把浏览器上地址复制下来是：http://localhost:8089/swagger%E2%80%90ui.html

修改地址如下：
http://localhost:8001/swagger-ui.html
立马不再404了，所以根本不需要什么addResourceHandlers
