Doris注意事项，Doris部署在阿里云，写不进去数据

1.Doris官网

Doris官网https://doris.apache.org/

2.根本原因

本地idea访问FE，FE会返回BE的地址，但是在服务器上通过ip addr查看，发现只有局域网IP，所以FE返回了局域网的IP，导致idea连接不上BE

3.解决办法

重写BackendV2类，返回公网IP即可。

在项目下新建包名

org.apache.doris.flink.rest.models

然后放入 BackendV2类

package org.apache.doris.flink.rest.models;import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import com.fasterxml.jackson.annotation.JsonProperty;import java.util.List;/*** @Project_Name:Realtime* @Package_Name:org.apache.doris.flink.rest.models* @Class_Name:BackendV2* @Auther:zhang pengyun* @Date:2023-07-25 21:06* @Description:*/
@JsonIgnoreProperties(ignoreUnknown = true)
public class BackendV2 {@JsonProperty(value = "backends")private List<BackendRowV2> backends;public List<BackendRowV2> getBackends() {return backends;}public void setBackends(List<BackendRowV2> backends) {this.backends = backends;}public static class BackendRowV2 {public String ip;public int http_port;public boolean is_alive;public String getIp() {return ip;}public void setIp(String ip) {this.ip = ip;}public int getHttpPort() {return http_port;}public void setHttpPort(int httpPort) {this.http_port = httpPort;}public boolean isAlive() {return is_alive;}public void setAlive(boolean alive) {is_alive = alive;}public String toBackendString(){return "47.92.168.70" + ":" + http_port;}}
}

然后重写修改toBackendString()方法，将公网IP写死返回，如果有多个BE，可以通过判断ip属性的值，动态返回。
