    1.获得所有index

    rest方式:

    curl 'localhost:9200/_cat/indices?v'

    JAVA方式:

    GetIndexResponse response = client.admin().indices().prepareGetIndex().execute().actionGet();
            System.out.println(response.getIndices().length);
            String[] indices = response.getIndices();
            for(String indice : indices){
                System.out.println(indice);
            }
    

    2.获得所有type

    rest方式:

    curl -XGET 'http://localhost:9200/_mapping?pretty=true'

    非格式化:

    curl -s -XGET 'http://localhost:9200/_mapping'

    JAVA方式:

    GetMappingsResponse res = null;
    try {
        res = client.admin().indices().getMappings(new GetMappingsRequest().indices(indice)).get();
    } catch (InterruptedException e) {
        e.printStackTrace();
    } catch (ExecutionException e) {
        e.printStackTrace();
    }
    ImmutableOpenMap<String, MappingMetaData> mapping  = res.mappings().get(indice);
    for (ObjectObjectCursor<String, MappingMetaData> c : mapping) {
        System.out.println("type = "+c.key);
        System.out.println("columns = "+c.value.source());
    }
