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());
}
