• setPersistenceUnitManager

  public void setPersistenceUnitManager​(PersistenceUnitManager persistenceUnitManager)

  Set the PersistenceUnitManager to use for obtaining the JPA persistence unit that this FactoryBean is supposed to build an EntityManagerFactory for.

  The default is to rely on the local settings specified on this FactoryBean, such as "persistenceXmlLocation", "dataSource" and "loadTimeWeaver".

  For reuse of existing persistence unit configuration or more advanced forms of custom persistence unit handling, consider defining a separate PersistenceUnitManager bean (typically a DefaultPersistenceUnitManager instance) and linking it in here. persistence.xml location, DataSource configuration and LoadTimeWeaver will be defined on that separate DefaultPersistenceUnitManager bean in such a scenario.

• setPersistenceXmlLocation

  public void setPersistenceXmlLocation​(String persistenceXmlLocation)

  Set the location of the persistence.xml file we want to use. This is a Spring resource location.

  Default is "classpath:META-INF/persistence.xml".

  NOTE: Only applied if no external PersistenceUnitManager specified.

  参数:

  persistenceXmlLocation - a Spring resource String identifying the location of the persistence.xml file that this LocalContainerEntityManagerFactoryBean should parse

• setPersistenceUnitName

  public void setPersistenceUnitName​(@Nullable
                                     String persistenceUnitName)

  Uses the specified persistence unit name as the name of the default persistence unit, if applicable.

  NOTE: Only applied if no external PersistenceUnitManager specified.

  DefaultPersistenceUnitManager.setDefaultPersistenceUnitName(java.lang.String)

• setPersistenceUnitRootLocation

  public void setPersistenceUnitRootLocation​(String defaultPersistenceUnitRootLocation)

  Set a persistence unit root location for the default persistence unit.

  Default is "classpath:", that is, the root of the current classpath (nearest root directory). To be overridden if unit-specific resolution does not work and the classpath root is not appropriate either.

  NOTE: Only applied if no external PersistenceUnitManager specified.

• setPackagesToScan

  public void setPackagesToScan​(String... packagesToScan)

  Set whether to use Spring-based scanning for entity classes in the classpath instead of using JPA's standard scanning of jar files with persistence.xml markers in them. In case of Spring-based scanning, no persistence.xml is necessary; all you need to do is to specify base packages to search here.

  Default is none. Specify packages to search for autodetection of your entity classes in the classpath. This is analogous to Spring's component-scan feature (ClassPathBeanDefinitionScanner).

  Note: There may be limitations in comparison to regular JPA scanning. In particular, JPA providers may pick up annotated packages for provider-specific annotations only when driven by persistence.xml. As of 4.1, Spring's scan can detect annotated packages as well if supported by the given JpaVendorAdapter (e.g. for Hibernate).

  If no explicit mapping resources have been specified in addition to these packages, Spring's setup looks for a default META-INF/orm.xml file in the classpath, registering it as a mapping resource for the default unit if the mapping file is not co-located with a persistence.xml file (in which case we assume it is only meant to be used with the persistence units defined there, like in standard JPA).

  NOTE: Only applied if no external PersistenceUnitManager specified.

  参数:

  packagesToScan - one or more base packages to search, analogous to Spring's component-scan configuration for regular Spring components

• setMappingResources

  public void setMappingResources​(String... mappingResources)

  Specify one or more mapping resources (equivalent to <mapping-file> entries in persistence.xml) for the default persistence unit. Can be used on its own or in combination with entity scanning in the classpath, in both cases avoiding persistence.xml.

  Note that mapping resources must be relative to the classpath root, e.g. "META-INF/mappings.xml" or "com/mycompany/repository/mappings.xml", so that they can be loaded through ClassLoader.getResource.

  If no explicit mapping resources have been specified next to packages to scan, Spring's setup looks for a default META-INF/orm.xml file in the classpath, registering it as a mapping resource for the default unit if the mapping file is not co-located with a persistence.xml file (in which case we assume it is only meant to be used with the persistence units defined there, like in standard JPA).

  Note that specifying an empty array/list here suppresses the default META-INF/orm.xml check. On the other hand, explicitly specifying META-INF/orm.xml here will register that file even if it happens to be co-located with a persistence.xml file.

  NOTE: Only applied if no external PersistenceUnitManager specified.

• setSharedCacheMode

  public void setSharedCacheMode​(SharedCacheMode sharedCacheMode)

  Specify the JPA 2.0 shared cache mode for this persistence unit, overriding a value in persistence.xml if set.

  NOTE: Only applied if no external PersistenceUnitManager specified.

  从以下版本开始:

  4.0

• setValidationMode

  public void setValidationMode​(ValidationMode validationMode)

  Specify the JPA 2.0 validation mode for this persistence unit, overriding a value in persistence.xml if set.

  NOTE: Only applied if no external PersistenceUnitManager specified.

  从以下版本开始:

  4.0

  另请参阅:

  PersistenceUnitInfo.getValidationMode(), setPersistenceUnitManager(org.springframework.orm.jpa.persistenceunit.PersistenceUnitManager)

• setDataSource

  public void setDataSource​(DataSource dataSource)

  Specify the JDBC DataSource that the JPA persistence provider is supposed to use for accessing the database. This is an alternative to keeping the JDBC configuration in persistence.xml, passing in a Spring-managed DataSource instead.

  In JPA speak, a DataSource passed in here will be used as "nonJtaDataSource" on the PersistenceUnitInfo passed to the PersistenceProvider, as well as overriding data source configuration in persistence.xml (if any). Note that this variant typically works for JTA transaction management as well; if it does not, consider using the explicit setJtaDataSource(javax.sql.DataSource) instead.

  NOTE: Only applied if no external PersistenceUnitManager specified.

  PersistenceUnitInfo.getNonJtaDataSource(), setPersistenceUnitManager(org.springframework.orm.jpa.persistenceunit.PersistenceUnitManager)

• setJtaDataSource

  public void setJtaDataSource​(DataSource jtaDataSource)

  Specify the JDBC DataSource that the JPA persistence provider is supposed to use for accessing the database. This is an alternative to keeping the JDBC configuration in persistence.xml, passing in a Spring-managed DataSource instead.

  In JPA speak, a DataSource passed in here will be used as "jtaDataSource" on the PersistenceUnitInfo passed to the PersistenceProvider, as well as overriding data source configuration in persistence.xml (if any).

  NOTE: Only applied if no external PersistenceUnitManager specified.

• setPersistenceUnitPostProcessors

  public void setPersistenceUnitPostProcessors​(PersistenceUnitPostProcessor... postProcessors)

  Set the PersistenceUnitPostProcessors to be applied to the PersistenceUnitInfo used for creating this EntityManagerFactory.

  Such post-processors can, for example, register further entity classes and jar files, in addition to the metadata read from persistence.xml.

  NOTE: Only applied if no external PersistenceUnitManager specified.

  另请参阅:

  setPersistenceUnitManager(org.springframework.orm.jpa.persistenceunit.PersistenceUnitManager)

• setLoadTimeWeaver

  public void setLoadTimeWeaver​(LoadTimeWeaver loadTimeWeaver)

  Specify the Spring LoadTimeWeaver to use for class instrumentation according to the JPA class transformer contract.

  It is a not required to specify a LoadTimeWeaver: Most providers will be able to provide a subset of their functionality without class instrumentation as well, or operate with their VM agent specified on JVM startup.

  In terms of Spring-provided weaving options, the most important ones are InstrumentationLoadTimeWeaver, which requires a Spring-specific (but very general) VM agent specified on JVM startup, and ReflectiveLoadTimeWeaver, which interacts with an underlying ClassLoader based on specific extended methods being available on it.

  NOTE: As of Spring 2.5, the context's default LoadTimeWeaver (defined as bean with name "loadTimeWeaver") will be picked up automatically, if available, removing the need for LoadTimeWeaver configuration on each affected target bean. Consider using the context:load-time-weaver XML tag for creating such a shared LoadTimeWeaver (autodetecting the environment by default).

  NOTE: Only applied if no external PersistenceUnitManager specified. Otherwise, the external PersistenceUnitManager is responsible for the weaving configuration.

  指定者:
