java - 使用 Spring Boot 的 Elasticsearch 无法正常工作

Question

我是 elasticsearch 的新手，我想将我使用 Springboot (1.3.1.RELEASE) 开发的 web 应用程序连接到安装在 unix VM 中的远程 Elasticsearch 实例，因此我将以下内容添加到我的 pom.xml 文件中。 XML

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>

这是我application.yml中的配置

 spring:
   data:
     elasticsearch:
       host: 192.168.56.101
       port: 9300
       cluster-nodes: 192.168.56.101:9300

但我遇到以下异常:

有人知道这个异常的原因吗？

看起来与安装的 ElasticSearch (2.1.1) 版本不兼容。

是不是说最新版的elasticsearch不能用最新版的springboot？然后我应该降级我的 Elasticsearch 版本还是有人知道任何其他修复？

如果有帮助，这是我创建的文档:

@Document(indexName = "lng_index",type = "")
public class LanguageDoc {

@Id
private String id;

private String text;

public LanguageDoc() {
}

public LanguageDoc(String id, String text) {
    this.id = id;
    this.text = text;
}

public String getId() {
    return id;
}

public void setId(String id) {
    this.id = id;
}

public String getText() {
    return text;
}

public void setText(String text) {
    this.text = text;
}
}

我的 Spring Data 存储库:

@Repository
public interface LanguageRepository extends   ElasticsearchRepository<LanguageDoc,String> {
}

还有 elasticsearch.yml :

# Lock the memory on startup:
#
# bootstrap.mlockall: true
#
# Make sure that the `ES_HEAP_SIZE` environment variable is set to about   half the memory
# available on the system and that the owner of the process is allowed to   use this limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -------------------------------  ----
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
#   network.host: 192.168.0.1
network.host: 0.0.0.0
#
# Set a custom port for HTTP:
#
# http.port: 9200
#
# For more information, see the documentation at:
# <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules- network.html>

提前感谢您的帮助!!

郑重声明，为了防止其他人遇到同样的问题，我已经通过将 ElasticSearch 的版本降级到 1.5.2 来修复它(与 Sprinboot 附带的内存中的 elasticSearch 实例相同)
