（elasticsearch-rest-client是官方提供的操作Elasticsearch的方式类似与jabc，fastjson是用来解析结果）
为什么使用ais
对空值的处理 更简单接近原生的代码操作
estemplate.term("worker","farmer"); //这是查询worker属性为farmer的结果
自动映射结果
@RequestMapping("terms")
public List<User> terms() throws IOException {
estemplate.terms("age",25,35,10,68);
return estemplate.execute(index,User.class);
}
可以直接复制kibana中的代码
@RequestMapping("/findCustom")
public List<User> findCustom(User user) throws IllegalAccessException, NoSuchFieldException, IOException {
String script="GET demo/_search\n" +
"{\n" +
" \"query\": {\n" +
" \"bool\": {\n" +
" \"must\": [\n" +
" {\n" +
" \"wildcard\": {\n" +
" \"name\": {\n" +
" \"value\": \"#{name}\"\n" +
" }\n" +
" }\n" +
" },\n" +
" {\n" +
" \"term\": {\n" +
" \"id\": {\n" +
" \"value\": \"#{id}\"\n" +
" }\n" +
" }\n" +
" }\n" +
" ],\n" +
" \"must_not\": [\n" +
" {\n" +
" \"range\": {\n" +
" \"age\": {\n" +
" \"gte\": #{age}\n" +
" }\n" +
" }\n" +
" }\n" +
" ]\n" +
" }\n" +
" },\n" +
" \"from\": \"#{pageFrom}\",\n" +
" \"size\": \"#{pageSize}\"\n" +
"}";
return estemplateCustom.excute(script,user);
}
对复杂需求的处理可以使用json和java代码
@Elasticsearch
public interface UserJson {
List<User> findName(String name);
List<User> findIdName(String name,String id);
}
{
"findName": {
"requestMethod": "GET",
"index": "demo/_search",
"script": {
"query": {
"wildcard": {
"name": {
"value": "#{name}"
}
}
}
}
},
"findIdName": {
"requestMethod": "GET",
"index": "demo/_search",
"script": {
"query": {
"bool": {
"must": [
{
"wildcard": {
"name": {
"value": "#{name}"
}
}
},
{
"term": {
"id": {
"value": "#{id}"
}
}
}
]
}
}
}
}
}
简单配置 elasticsearch.ais.url=node-3:9200 集群则用逗号隔开
elasticsearch.ais.aisResource=com.ais @Elasticsearch注解的接口位置，不配置则扫描所有路径，会导致springboot启动较慢，建议配置为项目路径
elasticsearch.ais.userName="" 用户名
elasticsearch.ais.passWard="" 密码
elasticsearch.ais.socketTimeout=30000 socket连接超时时间
elasticsearch.ais.connectTimeout=10000 connect连接超时时间
elasticsearch.ais.scheme="http" 访问方式
elasticsearch.ais.header="" 请求头
elasticsearch.ais.value="" 请求头对应值
elasticsearch.ais.jsonPath=static json文件路径
