元素详细资料

basePackageClasses

Class<?>[] basePackageClasses

Type-safe alternative to basePackages() for specifying the packages to scan for annotated components. The package of each class specified will be scanned. Consider creating a special no-op marker class or interface in each package that serves no purpose other than being referenced by this attribute.

默认值:

{}

basePackages

String[] basePackages

Base packages to scan for annotated components. value() is an alias for (and mutually exclusive with) this attribute. Use basePackageClasses() for a type-safe alternative to String-based package names.

默认值:

{}

bootstrapMode

org.springframework.data.repository.config.BootstrapMode bootstrapMode

Configures when the repositories are initialized in the bootstrap lifecycle. BootstrapMode.DEFAULT (default) means eager initialization except all repository interfaces annotated with Lazy, BootstrapMode.LAZY means lazy by default including injection of lazy-initialization proxies into client beans so that those can be instantiated but will only trigger the initialization upon first repository usage (i.e a method invocation on it). This means repositories can still be uninitialized when the application context has completed its bootstrap. BootstrapMode.DEFERRED is fundamentally the same as BootstrapMode.LAZY, but triggers repository initialization when the application context finishes its bootstrap.

返回:

从以下版本开始:

2.1

默认值:

org.springframework.data.repository.config.BootstrapMode.DEFAULT

considerNestedRepositories

boolean considerNestedRepositories

Configures whether nested repository-interfaces (e.g. defined as inner classes) should be discovered by the repositories infrastructure.

默认值:

false

enableDefaultTransactions

boolean enableDefaultTransactions

Configures whether to enable default transactions for Spring Data JPA repositories. Defaults to true. If disabled, repositories must be used behind a facade that's configuring transactions (e.g. using Spring's annotation driven transaction facilities) or repository methods have to be used to demarcate transactions.

返回:

whether to enable default transactions, defaults to true.

默认值:

true

entityManagerFactoryRef

String entityManagerFactoryRef

Configures the name of the EntityManagerFactory bean definition to be used to create repositories discovered through this annotation. Defaults to entityManagerFactory.

返回:

默认值:

"entityManagerFactory"

escapeCharacter

char escapeCharacter

Configures what character is used to escape the wildcards _ and % in derived queries with contains, startsWith or endsWith clauses.

返回:

a single character used for escaping.

默认值:

'\\'

excludeFilters

org.springframework.context.annotation.ComponentScan.Filter[] excludeFilters

Specifies which types are not eligible for component scanning.

默认值:

{}

includeFilters

org.springframework.context.annotation.ComponentScan.Filter[] includeFilters

Specifies which types are eligible for component scanning. Further narrows the set of candidate components from everything in basePackages() to everything in the base packages that matches the given filter or filters.

默认值:

{}

namedQueriesLocation

String namedQueriesLocation

Configures the location of where to find the Spring Data named queries properties file. Will default to META-INF/jpa-named-queries.properties.

返回:

默认值:

""

queryLookupStrategy

org.springframework.data.repository.query.QueryLookupStrategy.Key queryLookupStrategy

Returns the key of the QueryLookupStrategy to be used for lookup queries for query methods. Defaults to QueryLookupStrategy.Key.CREATE_IF_NOT_FOUND.

返回:

默认值:

org.springframework.data.repository.query.QueryLookupStrategy.Key.CREATE_IF_NOT_FOUND

repositoryBaseClass

Class<?> repositoryBaseClass

Configure the repository base class to be used to create repository proxies for this particular configuration.

返回:

从以下版本开始:

1.9

默认值:

org.springframework.data.repository.config.DefaultRepositoryBaseClass.class

repositoryFactoryBeanClass

Class<?> repositoryFactoryBeanClass

Returns the FactoryBean class to be used for each repository instance. Defaults to JpaRepositoryFactoryBean.

返回:

默认值:

org.springframework.data.jpa.repository.support.JpaRepositoryFactoryBean.class

repositoryImplementationPostfix

String repositoryImplementationPostfix

Returns the postfix to be used when looking up custom repository implementations. Defaults to Impl. So for a repository named PersonRepository the corresponding implementation class will be looked up scanning for PersonRepositoryImpl.

返回:

默认值:

"Impl"

transactionManagerRef

String transactionManagerRef

Configures the name of the PlatformTransactionManager bean definition to be used to create repositories discovered through this annotation. Defaults to transactionManager.

返回:

默认值:

"transactionManager"

value

String[] value

Alias for the basePackages() attribute. Allows for more concise annotation declarations e.g.: @EnableJpaRepositories("org.my.pkg") instead of @EnableJpaRepositories(basePackages="org.my.pkg").

默认值:

{}
