|
||||
## 1. 快速开始
|
||||
|
||||
### 1.1. 引入依赖
|
||||
|
||||
在 pom.xml 中引入以下依赖：
|
||||
|
||||
```xml
|
||||
<dependency>
|
||||
<groupId>org.elasticsearch.client</groupId>
|
||||
<artifactId>elasticsearch-rest-high-level-client</artifactId>
|
||||
<version>7.17.1</version>
|
||||
</dependency>
|
||||
```
|
||||
|
||||
### 1.2. 创建连接和关闭
|
||||
|
||||
```java
|
||||
// 创建连接
|
||||
RestHighLevelClient client = new RestHighLevelClient(
|
||||
RestClient.builder(
|
||||
new HttpHost("localhost", 9200, "http"),
|
||||
new HttpHost("localhost", 9201, "http")));
|
||||
|
||||
// 关闭
|
||||
client.close();
|
||||
```
|
||||
|
||||
## 2. 索引 API
|
||||
|
||||
### 2.1. 测试准备
|
||||
|
||||
```java
|
||||
public static final String INDEX = "mytest";
|
||||
public static final String INDEX_ALIAS = "mytest_alias";
|
||||
/**
|
||||
* {@link User} 的 mapping 结构（json形式）
|
||||
*/
|
||||
public static final String MAPPING_JSON =
|
||||
"{\n" + " \"properties\": {\n" + " \"_class\": {\n" + " \"type\": \"keyword\",\n"
|
||||
+ " \"index\": false,\n" + " \"doc_values\": false\n" + " },\n" + " \"description\": {\n"
|
||||
+ " \"type\": \"text\",\n" + " \"fielddata\": true\n" + " },\n" + " \"enabled\": {\n"
|
||||
+ " \"type\": \"boolean\"\n" + " },\n" + " \"name\": {\n" + " \"type\": \"text\",\n"
|
||||
+ " \"fielddata\": true\n" + " }\n" + " }\n" + "}";
|
||||
|
||||
@Autowired
|
||||
private RestHighLevelClient client;
|
||||
```
|
||||
|
||||
### 2.2. 创建索引
|
||||
|
||||
```java
|
||||
// 创建索引
|
||||
CreateIndexRequest createIndexRequest = new CreateIndexRequest(INDEX);
|
||||
|
||||
// 设置索引的 settings
|
||||
createIndexRequest.settings(
|
||||
Settings.builder().put("index.number_of_shards", 3).put("index.number_of_replicas", 2));
|
||||
|
||||
// 设置索引的 mapping
|
||||
createIndexRequest.mapping(MAPPING_JSON, XContentType.JSON);
|
||||
|
||||
// 设置索引的别名
|
||||
createIndexRequest.alias(new Alias(INDEX_ALIAS));
|
||||
|
||||
AcknowledgedResponse createIndexResponse = client.indices().create(createIndexRequest, RequestOptions.DEFAULT);
|
||||
Assertions.assertTrue(createIndexResponse.isAcknowledged());
|
||||
```
|
||||
|
||||
### 2.3. 删除索引
|
||||
|
||||
```java
|
||||
// 删除索引
|
||||
DeleteIndexRequest deleteIndexRequest = new DeleteIndexRequest(INDEX);
|
||||
AcknowledgedResponse deleteResponse = client.indices().delete(deleteIndexRequest, RequestOptions.DEFAULT);
|
||||
Assertions.assertTrue(deleteResponse.isAcknowledged());
|
||||
```
|
||||
|
||||
### 2.4. 判断索引是否存在
|
||||
|
||||
```java
|
||||
GetIndexRequest getIndexRequest = new GetIndexRequest(INDEX);
|
||||
Assertions.assertTrue(client.indices().exists(getIndexRequest, RequestOptions.DEFAULT));
|
||||
GetIndexRequest getIndexAliasRequest = new GetIndexRequest(INDEX_ALIAS);
|
||||
Assertions.assertTrue(client.indices().exists(getIndexAliasRequest, RequestOptions.DEFAULT));
|
||||
```
|
||||
|
||||

|
||||
### 3.1. 文档测试准备
|
||||
|
||||
```java
|
||||
public static final String INDEX = "mytest";
|
||||
public static final String INDEX_ALIAS = "mytest_alias";
|
||||
/**
|
||||
* {@link User} 的 mapping 结构（json形式）
|
||||
*/
|
||||
public static final String MAPPING_JSON =
|
||||
"{\n" + " \"properties\": {\n" + " \"_class\": {\n" + " \"type\": \"keyword\",\n"
|
||||
+ " \"index\": false,\n" + " \"doc_values\": false\n" + " },\n" + " \"description\": {\n"
|
||||
+ " \"type\": \"text\",\n" + " \"fielddata\": true\n" + " },\n" + " \"enabled\": {\n"
|
||||
+ " \"type\": \"boolean\"\n" + " },\n" + " \"name\": {\n" + " \"type\": \"text\",\n"
|
||||
+ " \"fielddata\": true\n" + " }\n" + " }\n" + "}";
|
||||
|
||||
@Autowired
|
||||
private RestHighLevelClient client;
|
||||
|
||||
@BeforeEach
|
||||
public void init() throws IOException {
|
||||
|
||||
// 创建索引
|
||||
CreateIndexRequest createIndexRequest = new CreateIndexRequest(INDEX);
|
||||
|
||||
// 设置索引的 settings
|
||||
createIndexRequest.settings(
|
||||
Settings.builder().put("index.number_of_shards", 3).put("index.number_of_replicas", 2));
|
||||
|
||||
// 设置索引的 mapping
|
||||
createIndexRequest.mapping(MAPPING_JSON, XContentType.JSON);
|
||||
|
||||
// 设置索引的别名
|
||||
createIndexRequest.alias(new Alias(INDEX_ALIAS));
|
||||
|
||||
AcknowledgedResponse response = client.indices().create(createIndexRequest, RequestOptions.DEFAULT);
|
||||
Assertions.assertTrue(response.isAcknowledged());
|
||||
|
||||
// 判断索引是否存在
|
||||
GetIndexRequest getIndexRequest = new GetIndexRequest(INDEX_ALIAS);
|
||||
Assertions.assertTrue(client.indices().exists(getIndexRequest, RequestOptions.DEFAULT));
|
||||
GetIndexRequest getIndexAliasRequest = new GetIndexRequest(INDEX_ALIAS);
|
||||
Assertions.assertTrue(client.indices().exists(getIndexAliasRequest, RequestOptions.DEFAULT));
|
||||
}
|
||||
|
||||
@AfterEach
|
||||
public void destroy() throws IOException {
|
||||
// 删除索引
|
||||
DeleteIndexRequest request = new DeleteIndexRequest(INDEX);
|
||||
AcknowledgedResponse response = client.indices().delete(request, RequestOptions.DEFAULT);
|
||||
Assertions.assertTrue(response.isAcknowledged());
|
||||
}
|
||||
```
|
||||
|
||||
### 3.2. 创建文档
|
||||
|
||||
RestHighLevelClient Api 使用 `IndexRequest` 来构建创建文档的请求参数。
|
||||
|
||||
【示例】创建 id 为 1 的文档
|
||||
|
||||
```java
|
||||
IndexRequest request = new IndexRequest("product");
|
||||
request.id("1");
|
||||
Product product = new Product();
|
||||
product.setName("机器人");
|
||||
product.setDescription("人工智能机器人");
|
||||
product.setEnabled(true);
|
||||
String jsonString = JSONUtil.toJsonStr(product);
|
||||
request.source(jsonString, XContentType.JSON);
|
||||
```
|
||||
|
||||
同步执行
|
||||
|
||||
```java
|
||||
IndexResponse indexResponse = client.index(request, RequestOptions.DEFAULT);
|
||||
```
|
||||
|
||||
异步执行
|
||||
|
||||
```java
|
||||
// 异步执行
|
||||
client.indexAsync(request, RequestOptions.DEFAULT, new ActionListener<IndexResponse>() {
|
||||
@Override
|
||||
public void onResponse(IndexResponse indexResponse) {
|
||||
System.out.println(indexResponse);
|
||||
}
|
||||
|
||||
@Override
|
||||
public void onFailure(Exception e) {
|
||||
System.out.println("执行失败");
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### 3.3. 删除文档
|
||||
|
||||
RestHighLevelClient Api 使用 `DeleteRequest` 来构建删除文档的请求参数。
|
||||
|
||||
【示例】删除 id 为 1 的文档
|
||||
|
||||
```java
|
||||
DeleteRequest deleteRequest = new DeleteRequest(INDEX_ALIAS, "1");
|
||||
```
|
||||
|
||||
同步执行
|
||||
|
||||
```java
|
||||
DeleteResponse deleteResponse = client.delete(deleteRequest, RequestOptions.DEFAULT);
|
||||
System.out.println(deleteResponse);
|
||||
```
|
||||
|
||||
异步执行
|
||||
|
||||
```java
|
||||
client.deleteAsync(deleteRequest, RequestOptions.DEFAULT, new ActionListener<DeleteResponse>() {
|
||||
@Override
|
||||
public void onResponse(DeleteResponse deleteResponse) {
|
||||
System.out.println(deleteResponse);
|
||||
}
|
||||
|
||||
@Override
|
||||
public void onFailure(Exception e) {
|
||||
System.out.println("执行失败");
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### 3.4. 更新文档
|
||||
|
||||
RestHighLevelClient Api 使用 `UpdateRequest` 来构建更新文档的请求参数。
|
||||
|
||||
【示例】更新 id 为 1 的文档
|
||||
|
||||
```java
|
||||
UpdateRequest updateRequest = new UpdateRequest(INDEX_ALIAS, "1");
|
||||
Product product3 = new Product();
|
||||
product3.setName("扫地机器人");
|
||||
product3.setDescription("人工智能扫地机器人");
|
||||
product3.setEnabled(true);
|
||||
String jsonString2 = JSONUtil.toJsonStr(product3);
|
||||
updateRequest.doc(jsonString2, XContentType.JSON);
|
||||
```
|
||||
|
||||
同步执行
|
||||
|
||||
```java
|
||||
UpdateResponse updateResponse = client.update(updateRequest, RequestOptions.DEFAULT);
|
||||
System.out.println(updateResponse);
|
||||
```
|
||||
|
||||
异步执行
|
||||
|
||||
```java
|
||||
client.updateAsync(updateRequest, RequestOptions.DEFAULT, new ActionListener<UpdateResponse>() {
|
||||
@Override
|
||||
public void onResponse(UpdateResponse updateResponse) {
|
||||
System.out.println(updateResponse);
|
||||
}
|
||||
|
||||
@Override
|
||||
public void onFailure(Exception e) {
|
||||
System.out.println("执行失败");
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### 3.5. 查看文档
|
||||
|
||||
RestHighLevelClient Api 使用 `GetRequest` 来构建查看文档的请求参数。
|
||||
|
||||
【示例】查看 id 为 1 的文档
|
||||
|
||||
```java
|
||||
GetRequest getRequest = new GetRequest(INDEX_ALIAS, "1");
|
||||
```
|
||||
|
||||
同步执行
|
||||
|
||||
```java
|
||||
GetResponse getResponse = client.get(getRequest, RequestOptions.DEFAULT);
|
||||
```
|
||||
|
||||
异步执行
|
||||
|
||||
```java
|
||||
client.getAsync(getRequest, RequestOptions.DEFAULT, new ActionListener<GetResponse>() {
|
||||
@Override
|
||||
public void onResponse(GetResponse getResponse) {
|
||||
System.out.println(getResponse);
|
||||
}
|
||||
|
||||
@Override
|
||||
public void onFailure(Exception e) {
|
||||
System.out.println("执行失败");
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### 3.6. 获取匹配条件的记录总数
|
||||
|
||||
```java
|
||||
@Test
|
||||
@DisplayName("获取匹配条件的记录总数")
|
||||
public void count() throws IOException {
|
||||
SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
|
||||
sourceBuilder.query(QueryBuilders.matchPhraseQuery("customer_gender", "MALE"));
|
||||
sourceBuilder.trackTotalHits(true);
|
||||
|
||||
CountRequest countRequest = new CountRequest(INDEX);
|
||||
countRequest.source(sourceBuilder);
|
||||
|
||||
CountResponse countResponse = client.count(countRequest, RequestOptions.DEFAULT);
|
||||
long count = countResponse.getCount();
|
||||
System.out.println("命中记录数：" + count);
|
||||
}
|
||||
```
|
||||
|
||||
### 3.7. 分页查询
|
||||
|
||||
```java
|
||||
@ParameterizedTest
|
||||
@ValueSource(ints = {0, 1, 2, 3})
|
||||
@DisplayName("分页查询测试")
|
||||
public void pageTest(int page) throws IOException {
|
||||
|
||||
int size = 10;
|
||||
int offset = page * size;

SearchResponse response = client.search(searchRequest, RequestOptions.DEFAULT);
|
||||
SearchHit[] hits = response.getHits().getHits();
|
||||
for (SearchHit hit : hits) {
|
||||
KibanaSampleDataEcommerceBean bean =
|
||||
BeanUtil.mapToBean(hit.getSourceAsMap(), KibanaSampleDataEcommerceBean.class, true,
|
||||
CopyOptions.create());
|
