ElasticSearch使用Java客户端创建索引index和映射mapping

1.创建工程，导入pom.xml坐标

    
        org.elasticsearch
        elasticsearch
        5.6.8
    
    
        org.elasticsearch.client
        transport
        5.6.8
    
    
        org.apache.logging.log4j
        log4j‐to‐slf4j
        2.9.1
    
    
        org.slf4j
        slf4j‐api
        1.7.24
    
    
        org.slf4j
        slf4j‐simple
        1.7.21
    
    
        log4j
        log4j
        1.2.12
    
    
        junit
        junit
        4.12
    

2.创建索引index

@Test
//创建索引
publicvoidtest1() throwsException{
    // 创建Client连接对象
    Settings settings=Settings.builder().put("cluster.name", "my‐elasticsearch").build();
    TransportClient client=new PreBuiltTransportClient(settings) .addTransportAddress(newInetSocketTransportAddress(InetAddress.getByName("127.0.0.1"),9300));
    //创建名称为blog2的索引
    client.admin().indices().prepareCreate("blog2").get();
    //释放资源
    client.close();
}

这样就可以看到新的索引：

但是当前映射没有信息：

3.创建映射mapping

@Test
//创建映射
publicvoidtest3() throwsException{
    // 创建Client连接对象
    Settings settings=Settings.builder().put("cluster.name", "my‐elasticsearch").build();
    TransportClient client=new PreBuiltTransportClient(settings)        .addTransportAddress(newInetSocketTransportAddress(InetAddress.getByName("127.0.0.1"),9300));
    // 添加映射
    /**
        * 格式：
        * "mappings" : {
            "article" : {
                "dynamic" : "false",
                "properties" : {
                    "id" : { "type" : "string" },
                    "content" : { "type" : "string" },
                    "author" : { "type" : "string" }
                }
            }
        }*/
    XContentBuilder builder=XContentFactory.jsonBuilder()
        .startObject()       
        .startObject("article")
        .startObject("properties") 
        .startObject("id")
        .field("type", "integer"
        .field("store", "yes")
        .endObject()
        .startObject("title")        
        .field("type", "string")
        .field("store", "yes")
        .field("analyzer", "ik_smart")                                                    
        .endObject()        
        .startObject("content")
        .field("type", "string")
        .field("store", "yes")
        .field("analyzer", "ik_smart")            
        .endObject()        
        .endObject()        
        .endObject()        
        .endObject();
    // 创建映射
    PutMappingRequestmapping=Requests.putMappingRequest("blog2")                
        .type("article").source(builder);
    client.admin().indices().putMapping(mapping).get();
    //释放资源
    client.close();
}

这样就能看到对应的映射信息了：
