Named Query DAO methods with Primitive types fail to compile ------------------------------------------------------------ Key: HBX-469 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-469 Project: Hibernate Tools Issue Type: Bug Components: hbm2java Affects Versions: 3.1beta1 Reporter: James Schopp Fix For: 3.2beta6 if you define a name query that receives a primitive or wrapper parameter, then the DAO method for the name query will always be generated with "primitive" type. This failsto compile, since the call to query.setParameter("paramName", value); takes an object, not a primitive. For example: <query name="com.mycom.persistence.Account.findCommercialAccountById"> from Account where accountTypeClass='C' and accountNumber=:accountNumber <query-param name="accountNumber" type="java.lang.Long" /> </query> This generates the code public List findCommercialAccountById(long accountNumber) { Query query = getSession(false) .getNamedQuery("com.alldata.ecis.persistence.Account.findCommercialAccountById"); query.setParameter("accountNumber", accountNumber); return query.list(); } This code does not compile. I beleive the fix might be as simple as modifying Cfg2JavaTool.asFinderArgumentList(): if ( type instanceof PrimitiveType ) { typeClass = ( (PrimitiveType) type ).getPrimitiveClass(); } else { typeClass = type.getReturnedClass(); } I think this should always return the type.getReturnedClass(), and never the primitive... ALSO: it would ne nice to have another Cfg2JavaTool function like asFinderArgumentList but that generates the list as parameters to the call, not the function definition. For example, if a named query takes params: Long accountNumer, String accountName then, maybe have function called asFinderCallerArgumentList() which would return accountNumer, accountName
