... ]]> The entity-mappings element is the root element of a mapping file. It contains the following four types of elements: 1. The persistence-unit-metadata element contains metadata for the entire persistence unit. It is undefined if this element occurs in multiple mapping files within the same persistence unit. 2. The package, schema, catalog and access elements apply to all of the entity, mapped-superclass and embeddable elements defined in the same file in which they occur. 3. The sequence-generator, table-generator, converter, named-query, named-native-query, named-stored-procedure-query, and sql-result-set-mapping elements are global to the persistence unit. It is undefined to have more than one sequence-generator or table-generator of the same name in the same or different mapping files in a persistence unit. It is undefined to have more than one named-query, named-native-query, sql-result-set-mapping, or named-stored-procedure-query of the same name in the same or different mapping files in a persistence unit. It is also undefined to have more than one converter for the same target type in the same or different mapping files in a persistence unit. 4. The entity, mapped-superclass and embeddable elements each define the mapping information for a managed persistent class. The mapping information contained in these elements may be complete or it may be partial. Metadata that applies to the persistence unit and not just to the mapping file in which it is contained. If the xml-mapping-metadata-complete element is specified, the complete set of mapping metadata for the persistence unit is contained in the XML mapping files for the persistence unit. These defaults are applied to the persistence unit as a whole unless they are overridden by local annotation or XML element settings. schema - Used as the schema for all tables, secondary tables, join tables, collection tables, sequence generators, and table generators that apply to the persistence unit catalog - Used as the catalog for all tables, secondary tables, join tables, collection tables, sequence generators, and table generators that apply to the persistence unit delimited-identifiers - Used to treat database identifiers as delimited identifiers. access - Used as the access type for all managed classes in the persistence unit cascade-persist - Adds cascade-persist to the set of cascade options in all entity relationships of the persistence unit entity-listeners - List of default entity listeners to be invoked on each entity in the persistence unit. Defines the settings and mappings for an entity. Is allowed to be sparsely populated and used in conjunction with the annotations. Alternatively, the metadata-complete attribute can be used to indicate that no annotations on the entity class (and its fields or properties) are to be processed. If this is the case then the defaulting rules for the entity and its subelements will be recursively applied. @Target(TYPE) @Retention(RUNTIME) public @interface Entity { String name() default ""; } This element determines how the persistence provider accesses the state of an entity or embedded object. @Target({TYPE, METHOD, FIELD}) @Retention(RUNTIME) public @interface AssociationOverride { String name(); JoinColumn[] joinColumns() default{}; JoinTable joinTable() default @JoinTable; } @Target({TYPE, METHOD, FIELD}) @Retention(RUNTIME) public @interface AttributeOverride { String name(); Column column(); } This element contains the entity field or property mappings. It may be sparsely populated to include only a subset of the fields or properties. If metadata-complete for the entity is true then the remainder of the attributes will be defaulted according to the default rules. @Target({METHOD, FIELD}) @Retention(RUNTIME) public @interface Basic { FetchType fetch() default EAGER; boolean optional() default true; } public enum CascadeType { ALL, PERSIST, MERGE, REMOVE, REFRESH, DETACH}; @Target({METHOD, FIELD}) @Retention(RUNTIME) public @interface CollectionTable { String name() default ""; String catalog() default ""; String schema() default ""; JoinColumn[] joinColumns() default {}; UniqueConstraint[] uniqueConstraints() default {}; Index[] indexes() default {}; } @Target({METHOD, FIELD}) @Retention(RUNTIME) public @interface Column { String name() default ""; boolean unique() default false; boolean nullable() default true; boolean insertable() default true; boolean updatable() default true; String columnDefinition() default ""; String table() default ""; int length() default 255; int precision() default 0; // decimal precision int scale() default 0; // decimal scale } @Target({}) @Retention(RUNTIME) public @interface ColumnResult { String name(); Class type() default void.class; } public enum ConstraintMode {CONSTRAINT, NO_CONSTRAINT, PROVIDER_DEFAULT}; @Target({}) @Retention(RUNTIME) public @interface ConstructorResult { Class targetClass(); ColumnResult[] columns(); } @Target({TYPE, METHOD, FIELD}) @Retention(RUNTIME) public @interface Convert { Class converter() default void.class; String attributeName() default ""; boolean disableConversion() default false; } @Target({TYPE, METHOD, FIELD}) @Retention(RUNTIME) public @interface Converter { boolean autoApply() default false; } @Target({TYPE}) @Retention(RUNTIME) public @interface DiscriminatorColumn { String name() default "DTYPE"; DiscriminatorType discriminatorType() default STRING; String columnDefinition() default ""; int length() default 31; } public enum DiscriminatorType { STRING, CHAR, INTEGER }; @Target({TYPE}) @Retention(RUNTIME) public @interface DiscriminatorValue { String value(); } @Target({METHOD, FIELD}) @Retention(RUNTIME) public @interface ElementCollection { Class targetClass() default void.class; FetchType fetch() default LAZY; } Defines the settings and mappings for embeddable objects.
