3. Apache Solr ...in a hurry...
4. Connection HTTP q=name:(spring data) AND type:solr&start=0&rows=10
5. Connection HTTP SolrJ q=name:(spring data) AND type:solr&start=0&rows=10 new SolrQuery("name:(spring data) AND type:solr") .setStart(0).setRows(10);
6. Solr Query public List<Product> findByNameOrDescription(String name, String description) { String queryString = "name:" + ClientUtils.escapeQueryChars(name) + " OR description:" + ClientUtils.escapeQueryChars(description); try { SolrQuery query = new SolrQuery(queryString); query.setStart(0).setRows(0); QueryResponse response = solrServer.query(query); long totalValues = response.getResults().getNumFound(); query.setRows(Long.valueOf(totalValues).intValue()); return solrServer.query(query).getBeans(Product.class); } catch (SolrServerException e) { throw ExceptionTranslator.translate(e); } return Collections.emptyList(); }
7. Spring-Data-Solr
8. Spring-Data-Solr Spring Data offers serveral APIs around a common SPI Integration with Apache Solr Community Project with support from Springsource
9. Connection HTTP SolrJ Spring Data Solr new SimpleQuery(new Criteria("name") .is("spring", "data").and("type").is("solr") ).setPageRequest(new PageRequest(0, 10)); q=name:(spring data) AND type:solr&start=0&rows=10 new SolrQuery("name:(spring data) AND type:solr") .setStart(0).setRows(10);
10. Solr Template
11. SolrTemplate Product product = new Product("foo"); solrTemplate.saveBean(prodcut); solrTemplate.commit(); //...
12. SolrTemplate Product product = new Product("foo"); solrTemplate.saveBean(prodcut); solrTemplate.commit(); //... Product recalled = solrTemplate.queryForObject( new SimpleQuery(new Criteria("id").is("foo")), Product.class); Page<Product> page = solrTemplate.queryForPage( new SimpleQuery(new SimpleStringCriteria("*:*"), Product.class); //...
13. SolrTemplate Product product = new Product("foo"); solrTemplate.saveBean(prodcut); solrTemplate.commit(); //... Product recalled = solrTemplate.queryForObject( new SimpleQuery(new Criteria("id").is("foo")), Product.class); Page<Product> page = solrTemplate.queryForPage( new SimpleQuery(new SimpleStringCriteria("*:*"), Product.class); //... solrTemplate.deleteById("foo"); solrTemplate.commit();
14. Repository
15. Repository interface ProductRepository extends SolrCrudRepository<Product, String> { }
16. Repository interface ProductRepository extends SolrCrudRepository<Product, String> { } Product product = new Product("foo"); repo.save(product) //...
17. Repository interface ProductRepository extends SolrCrudRepository<Product, String> { } Product product = new Product("foo"); repo.save(product) //... Product recalled = repo.findOne("foo"); Page<Product> page = repo.findAll();
18. Repository interface ProductRepository extends SolrCrudRepository<Product, String> { } Product product = new Product("foo"); repo.save(product) //... Product recalled = repo.findOne("foo"); Page<Product> page = repo.findAll(); //... repo.delete(product);
19. Derived Queries
20. Derived Queries interface ProductRepository extends SolrCrudRepository<Product, String> { }
21. Derived Queries interface ProductRepository extends SolrCrudRepository<Product, String> { Page<Product> findByNameStartingWith(String name, Pageable page); }
22. Derived Queries interface ProductRepository extends SolrCrudRepository<Product, String> { Page<Product> findByNameStartingWith(String name, Pageable page); List<Product> findByNameOrDescription(String name, String description); }
23. Derived Queries interface ProductRepository extends SolrCrudRepository<Product, String> { Page<Product> findByNameStartingWith(String name, Pageable page); List<Product> findByNameOrDescription(@Boost(2) String name, String description); }
24. /*Named*/ Queries
25. /*Named*/ Queries interface ProductRepository extends SolrCrudRepository<Product, String> { Page<Product> findByNameStartingWith(String name, Pageable page); List<Product> findByNameOrDescription(@Boost(2) String name, String description); }
26. /*Named*/ Queries interface ProductRepository extends SolrCrudRepository<Product, String> { @Query("name:?0*") Page<Product> findByNameStartingWith(String name, Pageable page); List<Product> findByNameOrDescription(@Boost(2) String name, String description); }
27. /*Named*/ Queries interface ProductRepository extends SolrCrudRepository<Product, String> { @Query("name:?0*") Page<Product> findByNameStartingWith(String name, Pageable page); @Query(name="findByNameOrDescriptionBoostNameBy2") List<Product> findByNameOrDescription(String name, String description); }
