spring-data-elasticsearch

问题 Elasticversion - 1.7.6 springboot - 1.3.5 Using spring-data-elasticsearch I have created a custom JSON mapping as advised elsewhere in order to support Java8 new datetime fields.

CustomConfig: @Bean @Autowired public ElasticsearchTemplate elasticsearchTemplate(Client client) { ObjectMapper objectMapper = new ObjectMapper(); objectMapper.registerModule(new JavaTimeModule()); return new

问题 I have successfully created a query using ElasticSearch's _plugin/head interface. The query is meant to return the latest timestamp for a specific device at a specific location. The query looks as follows: { "query":{ "bool":{ "must":[ { "term":{ "deviceevent.location.id":"1" } }, { "term":{ "deviceevent.deviceId":"AHE1LDD01" } } ] } }, "from":0, "size":1, "sort":{ "timestamp":{ "order":"desc" } } } The above query works as intended. Now using Spring-Boot and Spring-Data-ElasticSearch, I

问题 I am using spring-data-elasticsearch for a project to provide it with full text search functionality. We keep the real data in a relational database and relevant metadata along with respective id in elasticsearch.

I am building the search query based on search criteria and then performing a queryForIds(): SearchQuery searchQuery = new NativeSearchQueryBuilder() .withIndices

问题 My index has data as mentioned below.

问题 I'm using Elasticsearch 2.4 in a Spring Boot application and I need to execute _update_by_query request to the remote ES instance using Java API. I've found the way to accomplish this task at this question, but as for my case I've got an NPE trying to execute the .get() function. A module for ES included: compile 'org.elasticsearch.module:reindex:2.4.1' Here's a code snippet I use for testing right now: UpdateByQueryRequestBuilder request = UpdateByQueryAction.INSTANCE.newRequestBuilder
