mongodb - MongoException: Index with name: code already exists with different options -


i have mongodb collection term following structure

{     "_id" : "00002c34-a4ca-42ee-b242-e9bab8e3a01f",     "terminologyclass" : "user",     "code" : "x67",     "terminology" : "some term related notes",     "notes" : "some notes" }

and java class representing term collection term.java

@document public class term{        @id     protected string termid;      @indexed     protected string terminologyclass;      @indexed(unique=true)     protected string code;      @indexed     protected string terminology;      protected string notes;      //getters & setters }

i have many documents in term collection. added new field term.java as

@indexed protected string status;

after adding field status term.java, while inserting new term term collection getting exceptoin :

com.mongodb.mongoexception: index name: code exists different options

i using mongodb version : 2.6.5 , spring-data-mongodb version : 1.3.2

you have index on collection same name, different definition. guess current code index non-unique

try: db.term.getindexes()

if indeed case (you have non-unique index on code field), issue: db.term.dropindex("code_1") (replace code field index name).

next time boot application, it's supposed work alright.

alternatively, remove unique attribute @indexed annotation (if don't except unique).
