记录一下SpringBoot(2.0.4.RELEASE)+Elasticsearch(6.2.4)+Gradle整合的一个小例子。
1.在Gradle内加入相关jar包的依赖:
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‘) //添加Spring Data Elasticsearch依赖 compile(‘org.springframework.boot:spring-boot-starter-data-elasticsearch‘) //添加JNA依赖 compile(‘net.java.dev.jna:jna:4.3.0‘) compile(‘com.google.guava:guava:26.0-jre‘)
2.创建实体对象,并加入Elasticsearch的相关注释:
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索引名称 可以理解为数据库名 必须为小写不然会报 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; } public void setContent(String content) { this.content = content; } @Override public String toString() { return "Blog [id=" + id + ", title=" + title + ", summary=" + summary + ", content=" + content + "]"; } }
3.创建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.创建Controller并简单的实现添加及查询
@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.打开下载好的Elasticsearch(6.2.4)内的elasticsearch.bat文件,等待一会儿直到启动完成。
6.启动SpringBoot应用并简单的测试
添加一条数据:
