spring-es.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

SpringBeanFactory获取bean

package com.leaf.elasticsearch;
import lombok.extern.slf4j.Slf4j;
import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * @author ycc
 */
@Slf4j
public class SpringBeanFactory {
    private transient static volatile SpringBeanFactory INSTANCE = null;
    private ClassPathXmlApplicationContext context;

    public static SpringBeanFactory getInstance(String... files) {
        if (files.length == 0) {
            files = new String[]{"classpath*:spring-*.xml"};
        }
        if (INSTANCE == null) {
            synchronized (SpringBeanFactory.class) {
                if (INSTANCE == null) {
                    INSTANCE = new SpringBeanFactory(files);
                }
            }
        }
        return INSTANCE;
    }

    private SpringBeanFactory(String... files) {
        context = new ClassPathXmlApplicationContext(files);
        Runtime.getRuntime().addShutdownHook(new Thread() {
            @Override
            public void run() {
                log.info("close SpringBeanFactory in shutdown hook");
                context.close();
            }
        });
        context.start();
    }
    public <T> T getBean(Class<T> clazz) {
        return context.getBean(clazz);
    }
}

测试类

package com.leaf.elasticsearch;
import org.elasticsearch.index.query.QueryBuilders;
import org.springframework.data.domain.PageRequest;
import org.springframework.data.elasticsearch.core.ElasticsearchTemplate;
import org.springframework.data.elasticsearch.core.query.IndexQuery;
import org.springframework.data.elasticsearch.core.query.NativeSearchQuery;
import org.springframework.data.elasticsearch.core.query.UpdateQuery;
import java.util.List;

/**

public class TestEs {
    public static void main(String[] args) {
        ElasticsearchTemplate elasticsearchTemplate = SpringBeanFactory.getInstance().getBean(ElasticsearchTemplate.class);
        NativeSearchQuery searchQuery = new NativeSearchQuery(QueryBuilders.matchAllQuery());
        searchQuery.addIndices("skynet_social_twitter_status_2019_05");
        searchQuery.addTypes("status");
        searchQuery.setPageable(new PageRequest(1, 10));
        UpdateQuery updateQuery = new UpdateQuery();
        IndexQuery indexQuery = new IndexQuery();
        long count = elasticsearchTemplate.count(searchQuery);
        List<SocialStatus> socialStatusList = elasticsearchTemplate.queryForList(searchQuery, SocialStatus.class);
        System.out.println(count);
    }
}
