You need to add a filter to the class to filter out the many-to-many and many-to-one relationships in the hibernate configuration file.

Jsonconfig Config = new jsonconfig ();

Config. setjsonpropertyfilter (New propertyfilter (){

Public Boolean apply (Object source, string name, object Value ){

If (name. Equals ("emistpersonorgs ")){

Return true;

} Else {

Return false;

}

}

});

Jsonobject JSON = jsonobject. fromobject (reader, config );

 

This problem also involves the following exceptions:

I checked this issue on the Internet. Many people say it is an oracle-driven problem. The exception I encountered was that other object relationships in the object were not filtered out during JSON filtering, therefore, an exception is thrown.
