Ignore some classes while scanning PackagesToScan

applicationcontext, spring, spring-data, spring-data-jpa

Solution

I have been trying to solve the same problem and finally got a solution as below:

<bean id="mySessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="myDataSource"/>
    <property name="packagesToScan" value="com.mycompany.bean"/>
    <property name="entityTypeFilters" ref="packagesToScanIncludeRegexPattern">
    </property>
    <property name="hibernateProperties">
        // ...
    </property>
</bean>

<bean id="packagesToScanIncludeRegexPattern" class="org.springframework.core.type.filter.RegexPatternTypeFilter" >
    <constructor-arg index="0" value="^(?!com.mycompany.bean.Test).*"/>
</bean>

I realized that there is a `setEntityTypeFilters` function on the `LocalSessionFactoryBean` class which can be used to filter which classes to be included. In this example I used RegexPatternTypeFilter but there are other types of filters as well.

Also note that the filters work with include semantics. In order to convert to exclude semantics I had to use negative lookahead in the regex.

This example shows the xml configuration but it should be trivial to convert to java based configuration.

Problem

I've a package (say `packagesToScan`) containing Classes that I wish to persist annotated with `@Entity`. While defining `ApplicationContext` configuration, I've done as follows. ``` @Configuration @EnableJpaRepositories("packagesToScan") @EnableTransactionManagement @PropertySource("server/jdbc.properties") @ComponentScan("packagesToScan") public class JpaContext { ... // Other configurations .... @Bean public LocalContainerEntityManagerFactoryBean entityManagerFactory() { LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean(); emf.setDataSource(this.dataSource()); emf.setJpaVendorAdapter(this.jpaVendorAdapter()); emf.setPackagesToScan("packagesToScan"); emf.setJpaProperties(this.hibernateProperties()); return emf; } ``` ` While developing, I've some classes within `packagesToScan` which doesn't satisfy requirements for persistence (like no primary keys etc) and due to this I'm not allowed to run test because of `ApplicationContext` setup failure. Now, Is there any way that I can scan just some selected classes or ignore some classes within `packagesToScan`?
