Calling named query with `in()`, in Hibernate

Question

This is my Hibernate namedQuery:

@NamedQuery(name = "getLanguagesForIds", query = "select l from Language l where l.languageId in(:ids)")

When I tried to execute the query, Hibernate is throwing exception:

java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Integer

I am passing the language ids as comma separated, like 1,2. Does anyone know how to solve this issue?

Answer 1

使用List = new ArrayList来保存ID，并将其作为参数值而不是逗号分隔的字符串传递。
