java - Save entity containing gson atribute to ElasticSearch in Spring -


my spring application uses spring-data-elasticsearch (https://github.com/spring-projects/spring-data-elasticsearch).

i save following document elasticsearch database:

    @document(indexname = "documents", type = "customentity", replicas = 0, shards = 5)     public class customentity implements serializable{          @id         private string id;           @field(type = fieldtype.string)         private string field1;         @field(type = fieldtype.integer)         private int field2;         @field(type = fieldtype.object)  //not sure annotation should use         private jsonobject exportjson;   //gson object          ...getters , setters...     }

using way:

public class customentitydao {      @resource     elasticsearchtemplate elasticsearchtemplate;              public void insertcustomentity(customentity entity){                  indexquery indexquery = new indexquery();         indexquery.setid(entity.getcustomentityid());         indexquery.setobject(entity);          elasticsearchtemplate.index(indexquery);  //exception thrown      }     }

but i'm getting error:

com.fasterxml.jackson.databind.jsonmappingexception: jsonobject (through reference chain: data.nosql.entities.customentity ["exportjson"]->com.google.gson.jsonobject["asstring"])

i understand problem don't have clue how solve it. ideas please?

my guess jackson tries covert gson object string indexable es , doesn't know how that. if post full stack trace it'll more helpful, if have take guess need use @jsonserializer annotation on "exportjson" object.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
