SpringBootDataElasticSearch+JPA实现将ORACLE数据批量写入ElasticSearch

一、环境配置

ElasticSearch 5.6.10  windows版  安装head插件   安装教程：elasticsearch5.X安装和elasticsearch head插件安装

SpringBoot 2.0.2.RELEASE 通过MAVEN引入对应版本的spring boot data elasticsearch和JPA

pom.xml

	4.0.0

	com.geostar
	GeoDataElasticSearch
	0.0.1-SNAPSHOT
	jar

	GeoDataElasticSearch

application.properties

server.port=8090

#ES配置
spring.data.elasticsearch.cluster-name=elasticsearch
spring.data.elasticsearch.cluster-nodes=127.0.0.1:9300
#若没有下面的设置会报出elasticsearchTemplate注入Bean失败
spring.data.elasticsearch.repositories.enabled=true  

#ORACLE数据源
spring.orcl.type=com.alibaba.druid.pool.DruidDataSource
spring.orcl.driverClassName=oracle.jdbc.OracleDriver
spring.orcl.url=jdbc:oracle:thin:@127.0.0.1:1521:orcl
spring.orcl.username=scott
spring.orcl.password=tiger

# 下面为连接池的补充设置，应用到上面所有数据源中
# 初始化大小，最小，最大
spring.orcl.initialSize=5
spring.orcl.minIdle=5
spring.orcl.maxActive=30
# 配置获取连接等待超时的时间
spring.orcl.maxWait=60000
# 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 
spring.orcl.timeBetweenEvictionRunsMillis=60000
# 配置一个连接在池中最小生存的时间，单位是毫秒 
spring.orcl.minEvictableIdleTimeMillis=300000
spring.orcl.validationQuery=SELECT 1 FROM DUAL
spring.orcl.testWhileIdle=true
spring.orcl.testOnBorrow=true
spring.orcl.testOnReturn=false
spring.orcl.keepAlive=true
spring.orcl.validationQueryTimeout=10
# 打开PSCache，并且指定每个连接上PSCache的大小 
spring.orcl.poolPreparedStatements=true
spring.orcl.maxPoolPreparedStatementPerConnectionSize=20
# 配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙 
spring.orcl.filters=stat,wall,log4j
# 通过connectProperties属性来打开mergeSql功能；慢SQL记录
spring.orcl.connectionProperties=druid.stat.mergeSql\=true;druid.stat.slowSqlMillis\=5000

二、创建JPA DataSource

DataSourceConfigure类

package com.geostar.datasource;

import javax.sql.DataSource;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.jdbc.DataSourceBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;


@Configuration
public class DataSourceConfigure {

    @Bean(name = "orclDataSource")
    @ConfigurationProperties(prefix = "spring.orcl")
    public DataSource orclDataSource() {
        return  DataSourceBuilder.create().type(com.alibaba.druid.pool.DruidDataSource.class).build();
    }

}

JpaCrudServcie类（JpaRepository）

package com.geostar.jpa.repository;

import java.util.List;

import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.persistence.Query;

import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;



@Repository
public class JpaCrudServcie {
	
	@PersistenceContext(name = "entityManager")
	private EntityManager entityManager;
	
	@Transactional("transactionManagerJpa")
	public void save(Object object) {
		try {
			entityManager.persist(object);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
	
	@Transactional("transactionManagerJpa")
	public void saveOrupdate(Object object) {
		try {
			entityManager.merge(object);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
	
	@SuppressWarnings("unchecked")
	//jpa使用JPQL语句查询
	public List
