how to use Elasticsearch jsonBuilder() in java? - json

Question

I have a document with the following schema,
{
"_index": "test",
"_type": "user",
"_id": "2",
"_score": 1,
"_source": {
"id": 2,
"accountExpired": false,
"accountLocked": false,
"dateCreated": "2016-07-19T03:13:07Z",
"employee": {
"class": "bropen.framework.core.osm.Employee",
"id": 1
}
}
}
I want to modify the value of field "employee"
I have tried this:
String employee="\"{\"class\":\"bropen.framework.core.osm.Employee\",\"id\":1,\"birthdate\":null,\"code\":null,\"dateCreated\":\"2016-07-19T03:13:07Z\",\"degree\":null,\"disabled\":false,\"email\":null,\"entryDate\":null,\"graduateDate\":null,\"groups\":[],\"identities\":[{\"class\":\"bropen.framework.core.osm.EmployeeIdentity\",\"id\":1},{\"class\":\"bropen.framework.core.osm.EmployeeIdentity\",\"id\":33}],\"identityNumber\":null,\"lastUpdated\":\"2016-07-19T07:58:34Z\",\"level\":0.10,\"location\":null,\"mainIdentityId\":1,\"major\":null,\"mobile\":null,\"name\":\"张三\",\"nation\":null,\"nativePlace\":null,\"notes\":null,\"organization\":{\"class\":\"bropen.framework.core.osm.Organization\",\"id\":2},\"payrollPlace\":null,\"professionalRank\":null,\"qualification\":null,\"rank\":null,\"sequence\":10,\"sex\":null,\"syncId\":null,\"telephoneNumber\":null,\"title\":null,\"type\":1,\"user\":{\"class\":\"bropen.framework.core.security.User\",\"id\":2},\"workingDate\":null,\"workingYears\":null}\"";
try {
client.prepareUpdate("test", "user", "2")
.setDoc(jsonBuilder().startObject().field("testfield", employee).endObject()).get();
} catch (IOException e) {
e.printStackTrace();
}
return error info :
java.util.concurrent.ExecutionException: RemoteTransportException[[node-1][192.168.0.224:9300][indices:data/write/update]]; nested: RemoteTransportException[[node-1]
[192.168.0.224:9300][indices:data/write/update[s]]]; nested:

how to use jsonBuilder() to build a json like this:
employee:{
"id":"1",
"class":"bropen",
"name":"Tom"
}
and modify the value of field "employee"?
--------------update------------------
I tried again:
public static void upMethod1() {
XContentBuilder json;
try {
json = jsonBuilder().startObject("employee").field("id", 1)
.field("class", "bropen").field("name", "Tom").endObject();
UpdateRequest request = new UpdateRequest();
request.index("test");
request.type("user");
request.id("2");
request.doc(json);
client.update(request).get();
} catch (IOException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
} catch (ExecutionException e) {
e.printStackTrace();
}
}

Answer 1

updating document is easy when you use json builder.
in your case inner object name is employee so you have to make object with name as "employee".
below is the code that helps you to understand the use of json builder.
XContentBuilder json = jsonBuilder()
.startObject("employee")
.field("id", 1)
.field("class", "bropen")
.field("name","Tom")
.endObject();
UpdateRequest request = new UpdateRequest();
request.index("test");
request.type("user");
request.id("2");
request.doc(json);
client.update(request).get();
you can see generated json using below code
String output = builder.string();

Answer 2

json = jsonBuilder().startObject()
.startObject("employee")
.field("id", 1)
.field("class", "bropen")
.field("name", "Tom")
.endObject()
.endObject();
UpdateRequest request = new UpdateRequest();
request.index("test");
request.type("user");
request.id("2");
request.doc(json);
System.out.println(json.toString());
client.update(request).get();
