上篇我们说了index的 mapping,这一篇 我们说一下 java 作为 客户端 来操作ES,下面讲一下 添加
说明:.添加的方式 一般以json字符串 来添加
下面 我们以 ownused 索引为例讲解(ps:相应的 mapping 可自己建立 上一篇说过)
第一步:建立 实体类
package com.test.data;
import com.test.util.IpUtil;
import com.test.util.IPUtil;
/**
*
*zqz
*/
public class OwnUsedAsset{
/**
* 全省地址ID
*/
private long id;
/**
* 区域-归属地
*/
private String area;
/**
* IP
*/
private String IP;
/**
* ipLong 保持唯一性
*/
private long ipLong;
/**
* 状态值-1:正常资产 2:下线资产
*/
private long state;
/**
* 备注
*/
private String remark;
/**
* 备注
*/
private String downLineRemark;
private long createTime;
private long updateTime;
private long actionTime;
/**
* 字符串 格式
*/
private String detectTime;
public String getDownLineRemark() {
return downLineRemark;
}
public void setDownLineRemark(String downLineRemark) {
this.downLineRemark = downLineRemark;
}
public String getDetectTime() {
return detectTime;
}
public void setDetectTime(String detectTime) {
this.detectTime = detectTime;
}
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public long getCreateTime() {
return createTime;
}
public void setCreateTime(long createTime) {
this.createTime = createTime;
}
public long getUpdateTime() {
return updateTime;
}
public void setUpdateTime(long updateTime) {
this.updateTime = updateTime;
}
public long getActionTime() {
return actionTime;
}
public void setActionTime(long actionTime) {
this.actionTime = actionTime;
}
public String getArea() {
return area;
}
public void setArea(String area) {
this.area = area;
}
public long getState() {
return state;
}
public void setState(long state) {
this.state = state;
}
public String getRemark() {
return remark;
}
public void setRemark(String remark) {
this.remark = remark;
}
public String getIP() {
return IP;
}
public void setIP(String iP) {
this.ipLong = IpUtil.ipToLong(iP);
this.IP = iP;
}
public long getIpLong() {
return ipLong;
}
public void setIpLong(long ipLong) {
this.ipLong = ipLong;
}
}
package com.test.util;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
public class JsonUtil {
/**
* 由对象转化成json 格式,添加到数据库
*/
private static ObjectMapper objectMapper = new ObjectMapper();
public static String toJson(Object o){
try {
return objectMapper.writeValueAsString(o);
} catch (JsonProcessingException e) {
e.printStackTrace();
}
return "";
}
}
第三步:建立 ES Client工具类 获取 ESClient
package com.test.util;
import java.util.ArrayList;
import java.util.List;
import org.elasticsearch.ElasticsearchException;

/

*
*/
public abstract class EsClientUtil{
/**
* 是否为调试
*/
private static boolean Debug = false;
public Object execute(Object ... obj){
@SuppressWarnings("rawtypes")
List rsList = new ArrayList<>();
ESClient esclient = null;
try {
esclient = (!Debug)?getDefaultDelegateClient():buildClient();
if(null == esclient)
return rsList;
return executeIt(esclient, obj);
} catch (Exception e) {
}finally{
ESClientFactory.me().closeClient(esclient);
}
return rsList;
}
/**
* 接口 的 执行方法,需要重写
* @param esclient
* @param obj
* @return
*/
protected abstract Object executeIt(ESClient esclient,Object ... obj);
public static ESClient buildClient(){
Settings settings = ImmutableSettings.settingsBuilder()//集群名
.put("client.transport.sniff", true).put("cluster.name", "cupid-es-zhang-1").build();
@SuppressWarnings("resource")
TransportClient client = new TransportClient(settings)//地址+ 端口
.addTransportAddress(new InetSocketTransportAddress("192.168.1.10", 9300));
ESClient delegateClient = new ESClient(client, Type.local);
return delegateClient;
}
public static ESClient getDefaultDelegateClient(){
ESClient cupidClient = null;
try {
//cupidClient = ESClientFactory.me().getDefaultDelegateClient();// 系统封装,
} catch (Exception e) {
}
return (!Debug)?cupidClient
:buildClient();
}
// 判断 此索引是否 存在
public static boolean isExistIndex(String indexName){
boolean flag = false;
ESClient client =getDefaultDelegateClient();
try {
if(client != null){
flag =client.admin().indices().exists(
new IndicesExistsRequest()
.indices(new String[]{indexName}))
.actionGet().isExists();
}
} catch (ElasticsearchException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return flag;
}
}
