#### 执行代码 ####

@GetMapping("searchAll")
        public ESDatas<DiskFile> searchAll(){
            DiskFile diDiskFileDto = new DiskFile();
            diDiskFileDto.setDiskFileId("2");
            diDiskFileDto.setName("张三");
    
            DiskFile diDiskFileDto1 = new DiskFile();
            diDiskFileDto1.setDiskFileId("1");
            diDiskFileDto1.setName("李四");
    
            List<DiskFile> list = new ArrayList<>();
            list.add(diDiskFileDto);
            list.add(diDiskFileDto1);
            esUtil.addOrUpdateDocuments("diskFile",list);
    
            ESDatas<DiskFile> esDatas = esUtil.searchAll("diskFile",DiskFile.class);
    
            return esDatas;
        }

#### 页面报错 ####

Whitelabel Error Page
    This application has no explicit mapping for /error, so you are seeing this as a fallback.
    
    Tue Dec 25 16:38:25 CST 2018
    There was an unexpected error (type=Internal Server Error, status=500).
    {"error":{"root_cause":[{"type":"index_not_found_exception","reason":"no such index","resource.type":"index_or_alias","resource.id":"diskFile","index_uuid":"_na_","index":"diskFile"}],"type":"index_not_found_exception","reason":"no such index","resource.type":"index_or_alias","resource.id":"diskFile","index_uuid":"_na_","index":"diskFile"},"status":404}

#### 前言 ####

不算是SpringBoot 2.0 的坑，只是在开发项目的时候遇到的问题总结。

#### 控制台报错 ####

#### 解决方案 ####

*  修改为

@GetMapping("searchAll")
        public ESDatas<DiskFile> searchAll(){
            DiskFile diDiskFileDto = new DiskFile();
            diDiskFileDto.setDiskFileId("2");
            diDiskFileDto.setName("张三");
    
            DiskFile diDiskFileDto1 = new DiskFile();
            diDiskFileDto1.setDiskFileId("1");
            diDiskFileDto1.setName("李四");
    
            List<DiskFile> list = new ArrayList<>();
            list.add(diDiskFileDto);
            list.add(diDiskFileDto1);
            esUtil.addOrUpdateDocuments("disk_file",list);
    
            ESDatas<DiskFile> esDatas = esUtil.searchAll("disk_file",DiskFile.class);
    
            return esDatas;
        }

#### 结果-成功 ####

#### 总结 ####

ES在存储和查询对象时候，命名规则一定要注意 不要用“驼峰式” 命名，用 下划线“\_”隔开。
