Patrick Lübbecke ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=61a7428... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiZWUyM2RiMDY1... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-15553?atlOrigin=eyJpIjoiZWUyM2... ) HHH-15553 ( https://hibernate.atlassian.net/browse/HHH-15553?atlOrigin=eyJpIjoiZWUyM2... ) Attributes not found for composite-key mappings: "java.lang.IllegalArgumentException: Unable to locate Attribute with the the given name" ( https://hibernate.atlassian.net/browse/HHH-15553?atlOrigin=eyJpIjoiZWUyM2... ) Change By: Patrick Lübbecke ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=61a7428... ) We migrated +*Short summary:*+ it is not possible to fetch content from Hibernate mapping tables, that only have {{<composite-id>}} attributes. I have 3 tables: * User * Role * User_Role We configure our entities using. 6 to 5 hbm. 6 xml files. The mapping file for User_Role has just a composite keys based on the IDs of User and I am currently migrating legacy Criteria API calls to JPA CriteriaBuilder Role. When I try to call fetching a tuple of the method root.gey(key) mapping table , I get this exception error in Hibernate 5.6.11 : {{java.lang.IllegalArgumentException: Unable to locate Attribute with the the given name [userName] on this ManagedType [com.myapp.ums.business.impl.UmsUserRoleVOImpl]}} The reason for this is that the attributes that are set as key-properties could not be found in {{AbstractManagedType#getAttribute(String name)}}: !image-20220926-131848.png|width=1310,height=241! Here is the code I use to prepare the DB queries: {code:java}CriteriaBuilder cb = this.getSession().getCriteriaBuilder(); CriteriaQuery cq = cb.createQuery(aliasToBeanClass); Root root = cq.from(aliasToBeanClass); // aliasToBeanClass is set to UmsUserRoleVOImpl List<Predicate> predicates = new ArrayList<>(); predicates.add(cb.equal(root.get(key), value)); // key is set to "userName" - this line is causing the exception {code} *My mapping file* {{<?xml version="1.0"?>}} {{<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"}} {{        "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">}} {{<hibernate-mapping>}} {{    <class name="com.myapp.ums.business.impl.UmsUserRoleVOImpl" table="ums_t_user_role"}} {{           proxy="com.myapp.ums.common.business.UmsUserRoleVO">}} {{        <composite-id>}} {{            <key-property name="userName" type="java.lang.String" column="fk_user_id"/>}} {{            <key-property name="roleName" type="java.lang.String" column="fk_role_id"/>}} {{        </composite-id>}} {{    </class>}} {{</hibernate-mapping>}} *The interface:* {code:java}public interface UmsUserRoleVO extends AbstractBaseProperties { String ROLE_NAME = "roleName"; String USER_NAME = "userName"; String PROPERTIES = "properties"; String getUserName(); void setUserName(final String userName); String getRoleName(); void setRoleName(final String roleName); List<PmPropertyVO> getProperties(); void setProperties(List<PmPropertyVO> properties); }{code} *The entity:* {code:java}package com.myapp.ums.business.impl; public class UmsUserRoleVOImpl extends AbstractBasePropertiesImpl implements UmsUserRoleVO { private static final long serialVersionUID = 6390635151578885216L; private String roleName; private String userName; private List<PmPropertyVO> properties; public UmsUserRoleVOImpl() { } @Override public Long getRowguid() { return super.getRowguid(); } @Override public void setRowguid(final Long rowguid) { super.setRowguid(rowguid); } public String getRoleName() { return roleName; } public void setRoleName(String roleName) { this.roleName = roleName; } public List<PmPropertyVO> getProperties() { return properties; } public void setProperties(List<PmPropertyVO> properties) { this.properties = properties; } public boolean equals(Object o) { ... } public int hashCode() { ... } public String toString() { return roleName + " " + userName; } @Get(UmsUserRoleVO.USER_NAME) public String getUserName() { return this.userName; } @Set(UmsUserRoleVO.USER_NAME) public void setUserName(String userName) { this.userName = userName; } }{code} I think it has something to do with the mapping file not correctly processed.
