Java EL1057E:没有在上下文中注册bean解析器来解析对bean的访问

我一直在尝试使用多个索引编写Elasticsearch。目前我已经安装了SpringV5.2.3.RELEASE和SpringBootV2.2.4.RELEASE

我发现了几个解决方案，允许使用Spring的SPEL技术使用多个索引，但我无法使其工作

我目前拥有以下文件：

ElasticDBConfig.java

package edu.unifi.disit.datamanager.config;
@Configuration
@EnableTransactionManagement
@EnableElasticsearchRepositories(basePackages = { "edu.unifi.disit.datamanager.datamodel.elasticdb"})
public class ElasticDBDbConfig {

   @Value("${elasticsearch.protocol}")
   private String esProtocol;

   @Value("${elasticsearch.host}")
   private String esHost;

   @Value("${elasticsearch.port}")
   private int esPort;

   @Value("${elasticsearch.clustername}")
   private String esClusterName;

   @Bean(destroyMethod = "close")
     public RestHighLevelClient elasticsearchClient() { 
        return new RestHighLevelClient(RestClient.builder(new HttpHost(esHost,esPort,esProtocol)));
    }

@Bean
public ElasticsearchRestTemplate elasticsearchTemplate() {
    ElasticsearchRestTemplate elasticsearchTemplate = new 
    ElasticsearchRestTemplate(elasticsearchClient());

    elasticsearchTemplate.putMapping(KPIElasticValue.class);

    return elasticsearchTemplate;
}

ConfigIndexBean.java

package edu.unifi.disit.datamanager.config;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Component;

@Configuration
@Component("configIndexBean")
public class ConfigIndexBean {

@Value("${elasticsearch.dummyIndex}")
private String indexName;

public String getIndexName() {
    return indexName;
}

public void setIndexName(String indexName) {
    this.indexName = indexName;
}

}

package edu.unifi.disit.datamanager.config;

public class ConfigIndexBean {

    private static String indexName = "dummy";

    public static final String getIndexName() {
        return indexName;
    }

    public static void setIndexName(String indexName) {
        ConfigIndexBean.indexName = indexName;
    }

}

KPIElasticValue.java

package edu.unifi.disit.datamanager.datamodel.elasticdb;

@JsonInclude(JsonInclude.Include.NON_NULL)
@Entity
@JsonSerialize(using = KPIElasticValueSerializer.class)
@JsonDeserialize(using = KPIElasticValueDeserializer.class)
@ComponentScan(basePackages = "edu.unifi.disit.datamanager.config")
@Document(type = "_doc", indexName = "#{@configIndexBean.getIndexName()}")
public class KPIElasticValue {

你知道吗

我也尝试

@Document(type = "_doc", indexName = "#{configIndexBean.getIndexName()}")
@Document(type = "_doc", indexName = "#{configIndexBean.indexName}")

例外情况是：

EL1057E:没有在上下文中注册bean解析程序来解析对bean'configIndexBean'的访问。

我是这样解决的：

ConfigIndexBean.setIndexName("newindex");

ConfigIndexBean.java

package edu.unifi.disit.datamanager.config;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Component;

@Configuration
@Component("configIndexBean")
public class ConfigIndexBean {

@Value("${elasticsearch.dummyIndex}")
private String indexName;

public String getIndexName() {
    return indexName;
}

public void setIndexName(String indexName) {
    this.indexName = indexName;
}

}

package edu.unifi.disit.datamanager.config;

public class ConfigIndexBean {

    private static String indexName = "dummy";

    public static final String getIndexName() {
        return indexName;
    }

    public static void setIndexName(String indexName) {
        ConfigIndexBean.indexName = indexName;
    }

}

以及KPIElasticValue.java上的注释：

@Document(type = "_doc",indexName = "# 
{T(edu.unifi.disit.datamanager.config.ConfigIndexBean).getIndexName()}")

在服务中，在调用存储库之前，我更改索引如下：

ConfigIndexBean.setIndexName("newindex");

---

你的意思是，你有索引app-logs-1、app-logs-2、app-logs-3，你想请求它们，因为它们是单个索引？不，我有一些索引依赖于通过API获得的值。基于这些值，我想通过ConfigIndexBean类的setter更改索引，并通过存储库在正确的索引上写入。实际上没有办法。我可以在更高的层次上解决这个问题，您必须通过简单的

if（dispatchToIndexA）{use Document}else{DocumentB}

或通过实现自己的PostBean处理器和动态管理正确的索引来发送请求以批准索引。
