小编k9m*_*k9m的帖子

我正在尝试使用Java API连接到ElasticSearch服务器.我使用elasticsearch服务来启动/停止和弹性搜索头来可视化集群.群集/节点处于活动状态,REST API在9200上通过卷曲工作正常.我已经阅读了关于此主题的几乎所有帖子,但我无法使其工作,下面是我的详细信息:

我尝试了所有这些:

1. 在TransportClient中使用localhost,devhost1,127.0.0.1或网络上的实际IP
2. 取消注释config.yaml中的IP属性并放置127.0.0.1(服务器)
3. 检查端口9300是否可用,它是.

... 9200/_cluster /节点

{
  "ok": true,
  "cluster_name": "test",
  "nodes": {
    "NLVBbJpJTZWefeI2kQt3Tg": {
      "name": "inventory_management",
      "transport_address": "inet[/127.0.0.1:9300]",
      "hostname": "devhost1",
      "version": "0.90.5",
      "http_address": "inet[/127.0.0.1:9200]"
    }
  }
}

... 9200/_cluster /健康？漂亮=真

{
  "cluster_name" : "test",
  "status" : "green",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "active_primary_shards" : 0,
  "active_shards" : 0,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 0
}

Java代码:

Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "test").put("node.name", "inventory_management").build();
Client client = new TransportClient(settings).addTransportAddress(new InetSocketTransportAddress("localhost", …

我正在尝试使用Ebean在Play中创建以下类:

public class BaseModel extends Model {

    @Column(name = "created_at")
    public Date createdAt;

    @Column(name = "updated_at")
    public Date updatedAt;

    @PrePersist
    public void createdAt() {
        this.createdAt = this.updatedAt = new Date();
    }

    @PreUpdate
    public void updatedAt() {
        this.updatedAt = new Date();
    }

}

它编译没问题,但是当我用我的实体bean子类化这个类时(所以每个都会插入时间戳进行创建和更新)我在尝试点击应用程序时遇到以下异常:

play.api.UnexpectedException: Unexpected exception[PersistenceException: Error with [models.InventoryItem] I believe it is not enhanced but it's superClass [class models.BaseModel] is? (You are not allowed to mix enhancement in a single inheritance hierarchy)]
