Detailed examples of Spring Boot Integration Solr

Environmental preparation

• Install Solr: From Solr's official website (Welcome to Apache Solr - Apache Solr) Download and install the latest version, and then use the commandbin/solr startStart the Solr service and usebin/solr create -c mycoreCreate a new Solr core.
• Install JDK: Make sure that JDK 8 and above are installed.
• Configure Maven: Create Spring Boot project using Maven as a project building tool.

Add dependencies

In Spring Boot ProjectAdd the following dependencies to the file:

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

This dependency automatically configures Spring Data Solr-related components, including Solr client and Spring Solr support.

Configure Solr Connection

existorAdd Solr's connection configuration to the file, as shown below:

：

=http://localhost:8983/solr
=mycore

：

spring:
  data:
    solr:
      host: http://localhost:8983/solr
      core: mycore

Define entity classes

Create an entity class to map documents in Solr, as shown below:

package ;
import ;
import ;
import ;
@SolrDocument(collection = "mycore")
public class Product {
    @Id
    @Field
    private String id;
    @Field
    private String name;
    @Field
    private String description;
    @Field
    private double price;
    // Getters and Setters
}

in,@SolrDocument(collection = "mycore")Specifies the core name of Solr.@FieldAnnotations are used to map fields of an entity class to fields of a Solr document.

Writing Repository Interface

Create an inherited fromSolrCrudRepositoryThe interface to operate the data in Solr, the example is as follows:

package ;
import ;
import ;
import ;
public interface ProductRepository extends SolrCrudRepository<Product, String> {
    List<Product> findByNameContaining(String name);
}

Through inheritanceSolrCrudRepositoryInterface, which can facilitate the addition, deletion, modification and search of documents.findByNameContainingMethods can be used to fuzzy queries by name.

Create Service and Controller

Create Service: Encapsulate business logic, the example is as follows:

package ;
import ;
import ;
import ;
import ;
import ;
@Service
public class ProductService {
    @Autowired
    private ProductRepository productRepository;
    public void saveProduct(Product product) {
        (product);
    }
    public List<Product> searchByName(String name) {
        return (name);
    }
    public void deleteProduct(String id) {
        (id);
    }
}

Create Controller: Process HTTP requests, the examples are as follows:

package ;
import ;
import ;
import ;
import .*;
import ;
@RestController
@RequestMapping("/products")
public class ProductController {
    @Autowired
    private ProductService productService;
    @PostMapping
    public void addProduct(@RequestBody Product product) {
        (product);
    }
    @GetMapping("/search")
    public List<Product> searchProducts(@RequestParam String name) {
        return (name);
    }
    @DeleteMapping("/{id}")
    public void deleteProduct(@PathVariable String id) {
        (id);
    }
}

Sample Run and Test

Add products: After starting the Spring Boot application, send a POST request to add the product, such as using the curl command:

curl -X POST -H "Content-Type: application/json" -d '{"id":"1","name":"Laptop","description":"High performance laptop","price":1000}' http://localhost:8080/products

Search for products: Send GET request to search for products:

curl http://localhost:8080/products/search?name=Laptop

Delete the product: Send DELETE request to delete the product:

curl -X DELETE http://localhost:8080/products/1
