Question

我试图在SpringBoot 1.4中使用Jest 0.0.6 ElasticSearch客户端并出现以下错误。我认为这是因为SpringBoot尝试自动创建一个Jest Client以及一个健康检查，但旧的Jest客户端没有一些必需的类。

任何想法如何绕过这个？

我需要连接到旧的ElasticSearch v0.90.5服务器，此时我无法升级。如果您对如何最好地从SpringBoo连接到这样一个旧版本有任何想法，这也会非常有帮助。

从Spring Boot 1.4发行说明：

＆＃34; Jest支持

如果Jest在类路径上，则Spring Boot会自动配置JestClient和专用的HealthIndicator。这允许您使用Elasticsearch，即使spring-data-elasticsearch不在类路径上。＆＃34;

我在这个jest github页面中找到了。如果您使用es 0.90.5，则必须使用jest 0.0.6。并且，有一个spring boot依赖项parent，指定jest的版本为2.0.3：

<jest.version>2.0.3</jest.version>

自动配置代码位于：org.springframework.boot.autoconfigure.elasticsearch.jest.JestAutoConfiguration

将io.searchbox.client.JestClient添加到类路径时，将加载此自动配置类。

这是由Condition框架@ConditionalOnClass(JestClient.class)建立的。

您可以找到有关条件框架here

通过将exclude添加到启动类来排除此自动配置：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.elasticsearch.jest.JestAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;

@SpringBootApplication
@EnableAutoConfiguration(exclude = { JestAutoConfiguration.class})
public class App {

    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
}

将此排除添加到您启动课程后。你可以配置你拥有的jest客户端。

Springboot 1.4 + Jest 0.0.6
