IDEA下springboot+elasticsearch搭建

使用的工具：

IDEA 2018、elasticsearch-5.6.5；

1、下载elasticsearch，解压，打开config文件目录下的elasticsearch.yml文件，可在文件中配置集群名称、集群节点名、端口等信息；

2、打开idea，创建spring-boot工程，在web选项中勾选web，在nosql选项中勾选elasticsearch，点击next继续

3、在工程pom.xml中加入dependency（注意版本号对应，避免兼容问题），如下图：

<dependency>
            <groupId>org.elasticsearch</groupId>
            <artifactId>elasticsearch</artifactId>
            <version>5.6.5</version>
        </dependency>
        <dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>transport</artifactId>
            <version>5.6.5</version>
        </dependency>
        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-api</artifactId>
            <version>2.7</version>
        </dependency>
        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-core</artifactId>
            <version>2.7</version>
        </dependency>

4、在application.properties中配置elasticsearch，如下图：

# elasticsearch
spring.data.elasticsearch.cluster-name=elasticsearch(自行定义)
spring.data.elasticsearch.cluster-nodes=127.0.0.1:9300
#spring.data.elasticsearch.local=false
spring.data.elasticsearch.repositories.enable=true

5、编写configuration：

@Configuration
public class ElasticsearchConf {
    @Bean
    public ElasticsearchOperations elasticsearchTemplate(Client client) {
        return new ElasticsearchTemplate(client);
    }
}

6、编写dao层接口

@Component(value = "articleDao")
public interface ArticleDao extends ElasticsearchCrudRepository<Article, String> {
}

7、编写model，（index=》DB，type=》table）

@Document(indexName = "blog",type = "article", shards = 1,replicas = 0, refreshInterval = "-1")
public class Article {
    @Id
    private String id;
    private String title;
    private String content;
    private String[] newcontent;
    private String about;

    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 getContent() {
        return content;
    }

    public void setContent(String content) {
        this.content = content;
    }

    public String[] getNewcontent() {
        return newcontent;
    }

    public void setNewcontent(String[] newcontent) {
        this.newcontent = newcontent;
    }

    public String getAbout() {
        return about;
    }

    public void setAbout(String about) {
        this.about = about;
    }
}

8、编写controller（service由于懒得原因，暂省）

@Controller
@RequestMapping("/index")
public class IndexController {

    @Autowired
    private ArticleDao articleDao;

    @RequestMapping("/article")
    @ResponseBody
    public Article getArticle(HttpServletRequest request) {
        String id = request.getParameter("id");
        return articleDao.findById(id).get();
    }
}
