我正在开发一个计划将elasticsearch用作数据存储库的系统.我正在尝试选择开发我的应用程序的最佳方法,该应用程序可以索引和查询elasticsearch中的数据.我拥有的系统建立在Spring框架之上.

使用Spring-data-elasticsearch(https://github.com/spring-projects/spring-data-elasticsearch)是一个不错的选择吗？

或者使用elasticsearch核心库本身是一个不错的选择？

我需要处理嵌套数据(内部对象),但Spring-data-elasticsearch最近似乎没有操作.

我希望我能找到问题的解决方案.提前致谢.

大家好,所有的弹性研究大师.

我有数百万个数据要由elasticsearch Java API索引.elasticsearch的集群节点数为3(1作为主节点+ 2节点).

我的代码片段如下.

Settings settings = ImmutableSettings.settingsBuilder()
     .put("cluster.name", "MyClusterName").build();

TransportClient client = new TransportClient(settings);
String hostname = "myhost ip";
int port = 9300; 
client.addTransportAddress(new InetSocketTransportAddress(hostname, port));

BulkRequestBuilder bulkBuilder = client.prepareBulk();
BufferedReader br = new BufferedReader(new InputStreamReader(new DataInputStream(new FileInputStream("my_file_path"))));
long bulkBuilderLength = 0;
String readLine = "";
String index = "my_index_name";
String type = "my_type_name";
String id = "";

while((readLine = br.readLine()) != null){

    id = somefunction(readLine);
    String json = new ObjectMapper().writeValueAsString(readLine);
    bulkBuilder.add(client.prepareIndex(index, type, id)
        .setSource(json));
    bulkBuilderLength++;
    if(bulkBuilderLength …

我开始使用Minitest在 Rails 上进行单元测试。

这是我对Product模型的第一个测试用例。

require "test_helper"

class ProductTest < ActiveSupport::TestCase
  test "product price must be positive" do
    product = Product.new(title: "My Book Title",
                          description: "yyy",
                          image_url: "zzz.jpg")
    product.price = -1
    assert product.invalid?, "negative price of a product must be invalid."
    assert product.errors.has_key?(:price), "an invalid product must have an error"

    product.price = 0
    assert product.invalid?, "negative price of a product must be invalid."
    assert product.errors.has_key?(:price), "an invalid product must have an error"

    product.price = 1
    assert product.valid?, …
