Springboot (2.0.4.RELEASE) +elasticsearch (6.2.4) +gradle Simple integration

Record a small example of Springboot (2.0.4.RELEASE) +elasticsearch (6.2.4) +gradle integration.

1. Add dependencies to the relevant jar package within Gradle:

Compile (' Org.springframework.boot:spring-boot-starter-web ') compile (' Org.springframework.boot: Spring-boot-starter-thymeleaf ') compile (' ORG.SPRINGFRAMEWORK.BOOT:SPRING-BOOT-STARTER-DATA-JPA ')//Add Spring data Elasticsearch relies on compile (' org.springframework.boot:spring-boot-starter-data-elasticsearch ')//Add JNA dependency compile (' net.java.dev.jna:jna:4.3.0 ')

Compile (' Com.google.guava:guava:26.0-jre ')

2. Create the Entity object and add the relevant notes for Elasticsearch:

Package Com.wey.pojo.blog;import Java.io.serializable;import Org.springframework.data.annotation.id;import Org.springframework.data.elasticsearch.annotations.Document, @Document (indexname= "Blogcenter", type= "blog")// IndexName index name can be understood as the database name must be lowercase or it will be reported public class Blog implements serializable{private static final long Serialversionuid        = 1L;    @Id private String Id;    Private String title;    Private String Summary;        Private String content;    Protected Blog () {super ();        Public Blog (string title, string summary, string content) {this.title = title;        This.summary = Summary;    this.content = content;    } public String GetId () {return id;    } public void SetId (String id) {this.id = ID;    } public String GetTitle () {return title;    public void Settitle (String title) {this.title = title;    } public String Getsummary () {return summary; } public void SetSuMmary (String summary) {this.summary = summary;    } public String GetContent () {return content;    The public void SetContent (String content) {this.content = content; } @Override Public String toString () {return "Blog [id=" + ID + ", title=" + title + ", summary=" + Summary    + ", content=" + content + "]"; }}

3. Create Repository

Package Com.wey.repository;import Org.springframework.data.domain.page;import Org.springframework.data.domain.pageable;import Org.springframework.data.elasticsearch.repository.elasticsearchrepository;import Org.springframework.stereotype.component;import Com.wey.pojo.blog.blog;public Interface BlogRepository extends Elasticsearchrepository<blog, string> {}

4. Create a controller and simply implement add and query

@RestController @requestmapping ("/blogs") public class BlogController {     @Autowired     blogrepository Blogrepository;    @RequestMapping ("/add") Public    Blog Add (blog blog) {        return blogrepository.save (blog);    }           @GetMapping public    list<blog> findAll () {        iterable<blog> elements = Blogrepository.findall ();        arraylist<blog> list = lists.newarraylist (elements);        return list;    }        @GetMapping ("/delete/{id}") Public    string Remove (@PathVariable (name= "id") string id) {        Blogrepository.deletebyid (ID);        Return "Success";    }}

5. Open the Elasticsearch.bat file in the downloaded Elasticsearch (6.2.4) and wait a few moments until the boot is complete.

6. Start the Springboot application and simply test

Add a piece of data:

Query all data:
