SpringBoot2.0填坑（二）：elastic searc

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。
