1.2 CMS一键发布接口 
1.2.1 需求分析

接口的开发大部分还是复制代码，基本没毛病，一键发布页面的接口信息

 public CmsPostPageResult postPageQuick(CmsPage cmsPage) {

        //将页面信息存储到cms_page 集合中
        CmsPageResult save = this.save(cmsPage);
        if(!save.isSuccess()){
            ExceptionCast.cast(CommonCode.FAIL);
        }
        //得到页面的id
        CmsPage cmsPageSave = save.getCmsPage();
        String pageId = cmsPageSave.getPageId();

        //执行页面发布（先静态化、保存GridFS，向MQ发送消息）
        ResponseResult post = this.post(pageId);
        if(!post.isSuccess()){
            ExceptionCast.cast(CommonCode.FAIL);
        }
        //拼接页面Url= cmsSite.siteDomain+cmsSite.siteWebPath+ cmsPage.pageWebPath + cmsPage.pageName
        //取出站点id
        String siteId = cmsPageSave.getSiteId();
        CmsSite cmsSite = this.findCmsSiteById(siteId);
        //页面url
        String pageUrl =cmsSite.getSiteDomain() + cmsSite.getSiteWebPath() + cmsPageSave.getPageWebPath() + cmsPageSave.getPageName();
        return new CmsPostPageResult(CommonCode.SUCCESS,pageUrl);
    }

后面看视频有时复制代码，感觉这个课程好水！！操作成功

安装es，双击启动成功

运行他这个header失败，成功运行

 

 Es的文档创建和建立索引都是比较简单的操作，这里就不过多的赘述了

接下来又是复制代码，没得说，大部分情况都在复制代码

  //创建索引库
    @Test
    public void testCreateIndex() throws IOException {
        //创建索引对象
        CreateIndexRequest createIndexRequest = new CreateIndexRequest("xc_course");
        //设置参数
        createIndexRequest.settings(Settings.builder().put("number_of_shards","1").put("number_of_replicas","0"));
        //指定映射
        createIndexRequest.mapping("doc"," {\n" +
                " \t\"properties\": {\n" +
                "            \"studymodel\":{\n" +
                "             \"type\":\"keyword\"\n" +
                "           },\n" +
                "            \"name\":{\n" +
                "             \"type\":\"keyword\"\n" +
                "           },\n" +
                "           \"description\": {\n" +
                "              \"type\": \"text\",\n" +
                "              \"analyzer\":\"ik_max_word\",\n" +
                "              \"search_analyzer\":\"ik_smart\"\n" +
                "           },\n" +
                "           \"pic\":{\n" +
                "             \"type\":\"text\",\n" +
                "             \"index\":false\n" +
                "           }\n" +
                " \t}\n" +
                "}", XContentType.JSON);
        //操作索引的客户端
        IndicesClient indices = client.indices();
        //执行创建索引库
        CreateIndexResponse createIndexResponse = indices.create(createIndexRequest);
        //得到响应
        boolean acknowledged = createIndexResponse.isAcknowledged();
        System.out.println(acknowledged);

    }

    //删除索引库
    @Test
    public void testDeleteIndex() throws IOException {
        //删除索引对象
        DeleteIndexRequest deleteIndexRequest = new DeleteIndexRequest("xc_course");
        //操作索引的客户端
        IndicesClient indices = client.indices();
        //执行删除索引
        DeleteIndexResponse delete = indices.delete(deleteIndexRequest);
        //得到响应
        boolean acknowledged = delete.isAcknowledged();
        System.out.println(acknowledged);

    }

    //添加文档
    @Test
    public void testAddDoc() throws IOException {
        //文档内容
        //准备json数据
        Map<String, Object> jsonMap = new HashMap<>();
        jsonMap.put("name", "spring cloud实战");
        jsonMap.put("description", "本课程主要从四个章节进行讲解： 1.微服务架构入门 2.spring cloud 基础入门 3.实战Spring Boot 4.注册中心eureka。");
        jsonMap.put("studymodel", "201001");
        SimpleDateFormat dateFormat =new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        jsonMap.put("timestamp", dateFormat.format(new Date()));
        jsonMap.put("price", 5.6f);

        //创建索引创建对象
        IndexRequest indexRequest = new IndexRequest("xc_course","doc");
        //文档内容
        indexRequest.source(jsonMap);
        //通过client进行http的请求
        IndexResponse indexResponse = client.index(indexRequest);
        DocWriteResponse.Result result = indexResponse.getResult();
        System.out.println(result);

    }

    //查询文档
    @Test
    public void testGetDoc() throws IOException {
        //查询请求对象
        GetRequest getRequest = new GetRequest("xc_course","doc","tzk2-mUBGsEnDOUe482B");
        GetResponse getResponse = client.get(getRequest);
        //得到文档的内容
        Map<String, Object> sourceAsMap = getResponse.getSourceAsMap();
        System.out.println(sourceAsMap);
    }

 

这个ES 真心感觉光听一点用也没用，基本的语法都是那些，来来回都是简单的增删改查的应用，基本都是复制代码，建议跳过这一节的内容
