What is the solution to prevent repeated entities when using Criteria API for lazy associations fetch?

edit

One solution to prevent repeated entities when using Criteria API for lazy associations fetch is to use the distinct method of CriteriaQuery. This will eliminate duplicates from the result set. Another solution is to use the fetch method with the JoinType.LEFT parameter, as it will only fetch the associated entities once. Additionally, you can also use the setResultTransformer method to transform the result set into a customized format, which may eliminate duplicates as well.
