> entity.equals doesn't work correct with proxies > ----------------------------------------------- > > Key: HIB-138 > URL: http://jira.andromda.org/browse/HIB-138 > Project: Hibernate Cartridge > Type: Bug > Versions: 3.1M1 > Reporter: Patrik Jurica > Assignee: Carlos Cuenca > Priority: Minor > Attachments: hibernate.java.vm > > Generated Java code for entity.equals(Object object) doesn't work, when the > equaled paramater is a CGLIB proxy, beacuse "that.$attribute.name" is used. > But "that.$attribute.name" can be null in the proxy object. > "that.${attribute.getterName}()" must be used instead. > The corrected templates\hibernate\hibernate.java.vm follows: > ## > ## This macro will render the equals() method > ## If an entity is rendered, the attributeSet consists of the identifiers, > ## if an value type is renderer, the attributeSet consists of all attributes > ## > #macro (renderEqualsMethod $class $className $attributeSet) > public boolean equals(Object object) > { > #if ($attributeSet.empty) > return super.equals(object); > #else > if (this == object) > { > return true; > } > if (!(object instanceof $className)) > { > return false; > } > final $className that = ($className)object; > #foreach ($attribute in $attributeSet) > #set ($idType = $attribute.type) > #if ($idType.primitive) > if (this.$attribute.name != that.${attribute.getterName}()) > { > return false; > } > #elseif ($idType.arrayType) > if (!java.util.Arrays.equals(this.$attribute.name, > that.${attribute.getterName}())) > { > return false; > } > #else > if (this.$attribute.name == null || that.${attribute.getterName}() == > null || !this.${attribute.name}.equals(that.${attribute.getterName}())) > { > return false; > } > #end > #end > return true; > #end > } > #end > ## > ## This macro will render the hashCode() method > ## If an entity is rendered, the attributeSet consists of the identifiers, > ## if an value type is renderer, the attributeSet consists of all attributes > ## > #macro (renderHashCodeMethod $class $attributeSet) > public int hashCode() > { > #if ($attributeSet.empty) > return super.hashCode(); > #else > #if ($class.generalization) > int hashCode = super.hashCode(); > #else > int hashCode = 0; > #end > #foreach ($attribute in $attributeSet) > #set ($attrType = $attribute.type) > #if ($attribute.getterSetterTypeName == "boolean") > hashCode = 29 * hashCode + (${attribute.name} ? 1 : 0); > #elseif ($attrType.arrayType) > // arrays are not part of the hashCode calculation > #elseif ($attrType.primitive) > hashCode = 29 * hashCode + (int)${attribute.name}; > #else > hashCode = 29 * hashCode + (${attribute.name} == null ? 0 : > ${attribute.name}.hashCode()); > #end## if > #end## foreach > return hashCode; > #end## $attributeSet.empty > } > #end ------------------------------------------------------- This SF.Net email is sponsored by the JBoss Inc.
