是Spring Data + Spring Boot的新手。我已经下载了Spring Data项目，并试图在Eclipse中进行配置。
在执行项目时收到以下错误。
java.lang.IllegalStateException: Failed to execute CommandLineRunner
请找到我的Application.java文件

请找到我的application.properties文件

此外，我已经安装了ElasticSearch 6.2.3（最新版本）。但是在stacktrace中，它显示elasticsearch-2.4.4.jar:2.4.4。我该如何重新配置它？？
答案 0 :(得分：0)
据我所知，Spring-data-elastic-search不支持ES 6.2。如您在堆栈跟踪中所见，您的ES版本是2.4。
如果要使用6.2，则需要使用HignLevelRestClient（ES的基于Java的API）
这是ES 6.2的配置
@Configuration
public class ElasticSearchConfig extends AbstractFactoryBean {
private static final Logger LOG = LoggerFactory.getLogger(ElasticSearchConfig.class);
@Value("${spring.data.elasticsearch.cluster-nodes}")
private String clusterNodes;
@Value("${spring.data.elasticsearch.cluster-name}")
private String clusterName;
private RestHighLevelClient restHighLevelClient;
@Override
public void destroy() {
try {
if (restHighLevelClient != null) {
restHighLevelClient.close();
}
} catch (final Exception e) {
LOG.error("Error closing ElasticSearch client: ", e);
}
}
@Override
public Class<RestHighLevelClient> getObjectType() {
return RestHighLevelClient.class;
}
@Override
public boolean isSingleton() {
return false;
}
@Override
public RestHighLevelClient createInstance() {
return buildClient();
}
private RestHighLevelClient buildClient() {
try {
restHighLevelClient = new RestHighLevelClient(RestClient.builder(new HttpHost("localhost", 9200, "http"),
new HttpHost("localhost", 9201, "http")));
} catch (Exception e) {
LOG.error(e.getMessage());
}
return restHighLevelClient;
}
}
这是您的控制器：
@RestController
@RequestMapping("/books")
public class BookController {
@Autowired
private BookRepository bookRepository;
@GetMapping("/{id}")
public Map<String, Object> getBookById(@PathVariable String id){
return bookRepository.getBookById(id);
}
这是您的存储库：
@Repository
public class BookRepository {
private final String INDEX = "bookdata";
private final String TYPE = "books";
private RestHighLevelClient restHighLevelClient;
private ObjectMapper objectMapper;
public BookRepository( ObjectMapper objectMapper, RestHighLevelClient restHighLevelClient) {
this.objectMapper = objectMapper;
this.restHighLevelClient = restHighLevelClient;
}
public Map<String, Object> getBookById(String id){
GetRequest getRequest = new GetRequest(INDEX, TYPE, id);
GetResponse getResponse = null;
try {
getResponse = restHighLevelClient.get(getRequest);
} catch (java.io.IOException e){
e.getLocalizedMessage();
}
Map<String, Object> sourceAsMap = getResponse.getSourceAsMap();
return sourceAsMap;
}
这是您的主要课程：
@SpringBootApplication
public class ElasticsearchImplApplication {
public static void main(String[] args) {
SpringApplication.run(ElasticsearchImplApplication.class, args);
}
}
这是您的配置文件：
spring.data.elasticsearch.cluster-name=your-cluster
spring.data.elasticsearch.cluster-nodes=elasticsearch
我希望这会有所帮助。
