Solr項目簡介
Solr Spring Boot的學習項目
maven依賴
<dependency>

<artifactId>spring-boot-starter-data-solr</artifactId>

jdbc配置
spring:
data:
solr:
host: http://localhost:8983/solr
Solr repository
solr repository基于spring data jpa規(guī)范，對solr數(shù)據(jù)進行crud操作，如果項目本身就是使用hibernate+jpa建議使用這種方式進行solr數(shù)據(jù)操作。
public interface UserRepository extends SolrCrudRepository<User, Long> {
/**
* find user by username
*
* @param username
* @return
*/
public List<User> findByUsernameContains(String username);
}
添加索引、更新索引、刪除索引
@Test
public void index() {
User test =
User.builder().id("1002").username("test").password("123123").remark("solr user index test!").build();
User save = userRepository.save(test);
logger.debug(" user document saved with id: ", save.getId());
}
@Test
public void update() {
User user = User.builder().id("1001").createDate(new Date()).build();
userRepository.save(user);
logger.debug("user document updated with id: ", user.getId());
}
@Test
public void delete() {
User user = User.builder().id("1001").build();
userRepository.delete(user);
logger.debug("user document deleted with id: ", user.getId());
}
SolrJ
如果項目使用的是mybatis等其他orm框架，建議使用SolrJ對數(shù)據(jù)進行操作。
private static Logger logger = LoggerFactory.getLogger(SolrJTests.class);
@Autowired
private SolrClient solrClient;
private static final String SOLR_COLLECTION_USER = "user";
@Test
public void createIndex() throws Exception {
SolrInputDocument document = new SolrInputDocument();
document.addField("id", 1001L);
document.addField("username", "test");
document.addField("password", "123123");
document.addField("remark", "solr index test");
document.addField("createDate", new Date());
solrClient.add(SOLR_COLLECTION_USER, document);
solrClient.commit(SOLR_COLLECTION_USER);
}
@Test
public void query() throws Exception {
SolrQuery query = new SolrQuery();
query.set("q", "id:1001");
QueryResponse response = solrClient.query(SOLR_COLLECTION_USER, query);
List<User> userList = response.getBeans(User.class);
logger.debug("results size is: ", userList.size());
}
solr client auto config
如果項目使用的是springboot，建議使用spring data solr 進行solr數(shù)據(jù)操作，如果不使用springboot，可以使用如下配置實現(xiàn)solrclient的配置
@Configuration
@Component
public class SolrConfig {
/**
* solr host value
*/
@Value("${spring.data.solr.host}")
private String solrHost;
@Bean
public SolrClient solrClient() {
return new HttpSolrClient.Builder(solrHost).build();
}
@Bean
public SolrTemplate solrTemplate(SolrClient client) throws Exception {
return new SolrTemplate(client);
}
}
