SpringBoot(2.0.4.RELEASE)+Elasticsearch(6.2.4)+Gradle简单整合

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：

查询所有数据：
