二、Elasticsearch Repositories

2.1、简介

2.1.1、Spring命名空间

　　Spring Data Elasticsearch模块包含一个允许定义存储库bean的自定义名称空间以及用于实例化ElasticsearchServer的元素。使用repositories元素查找Spring Data存储库

示例、使用名称空间设置Elasticsearch存储库

SearchQuery searchQuery = new NativeSearchQueryBuilder()
.withQuery(matchAllQuery())
.withIndices("test-index")
.withTypes("test-type")
.withPageable(new PageRequest(0,1))
.build();
String scrollId = elasticsearchTemplate.scan(searchQuery,1000,false);
List<SampleEntity> sampleEntities = new ArrayList<SampleEntity>();
boolean hasRecords = true;
while (hasRecords){
Page<SampleEntity> page = elasticsearchTemplate.scroll(scrollId, 5000L , new ResultsMapper<SampleEntity>()
{
@Override
public Page<SampleEntity> mapResults(SearchResponse response) {
List<SampleEntity> chunk = new ArrayList<SampleEntity>();
for(SearchHit searchHit : response.getHits()){
if(response.getHits().getHits().length <= 0) {
return null;
}
SampleEntity user = new SampleEntity();
user.setId(searchHit.getId());
user.setMessage((String)searchHit.getSource().get("message"));
chunk.add(user);
}
return new PageImpl<SampleEntity>(chunk);
}
});
if(page != null) {
sampleEntities.addAll(page.getContent());
hasRecords = page.hasNextPage();
}
else{
hasRecords = false;
}
}
}
