Hibernate HBM Mapping Queries

Hibernate HBM Mapping Queries

Load this skill when querying Hibernate .hbm.xml mapping files — extracting entity-table bindings, property-column mappings, collection relationships (set/list/bag), foreign key discovery, or running batch scans across an enterprise persistence layer with 60+ HBM files.

Domain skill for dasel v3 queries against Hibernate .hbm.xml mapping files.

Attribute syntax (required): XML attributes use - prefix in dasel friendly mode (default). name → -name, table → -table, column → -column.

Parser flag (required): Always pass -i xml explicitly. Do not rely on auto-detection for .hbm.xml files.

Entity Discovery

# Fully qualified Java entity class name
dasel -f User.hbm.xml -i xml 'hibernate-mapping.class.-name'

# Database table the entity maps to
dasel -f User.hbm.xml -i xml 'hibernate-mapping.class.-table'

Property Column Mapping

# All mapped Java property names in the entity
dasel -f User.hbm.xml -i xml 'hibernate-mapping.class.property.map(-name)'

# All database column names for mapped properties
dasel -f User.hbm.xml -i xml 'hibernate-mapping.class.property.map(-column)'

Collection Relationships

<set>, <list>, <bag> — one-to-many relationships.

# All set collection names (one-to-many)
dasel -f User.hbm.xml -i xml 'hibernate-mapping.class.set.map(-name)'

# All list collection names
dasel -f User.hbm.xml -i xml 'hibernate-mapping.class.list.map(-name)'

Foreign Key Discovery

<many-to-one> — foreign key columns pointing to other entities.

# All foreign key column names
dasel -f User.hbm.xml -i xml 'hibernate-mapping.class.many-to-one.map(-column)'

# All referenced entity class names (the FK target)
dasel -f User.hbm.xml -i xml 'hibernate-mapping.class.many-to-one.map(-class)'

Batch Entity-Table Mapping

Extract entity→table pairs across all .hbm.xml files. Write to /tmp/ — never to the source tree.

for f in $(fdfind -e hbm.xml .); do
  entity=$(dasel -f "$f" -i xml 'hibernate-mapping.class.-name' 2>/dev/null)
  table=$(dasel -f "$f" -i xml 'hibernate-mapping.class.-table' 2>/dev/null)
  echo "$entity -> $table"
done > /tmp/entity_table_map.txt

Malformed files and missing attributes produce empty values via 2>/dev/null suppression.
