Không tự động kiểm tra thực thể JPA trong maven-verify

Question

Nếu tôi đặt persistence.xml trong thư mục src/test/META-INF, tự động kiểm tra thực thể không hoạt động với maven-verify. Khi persistence.xml nằm trong thư mục src/main/META-INF nó hoạt động.

Chạy thử nghiệm trong nhật thực hoạt động trong cả hai trường hợp.

Có cách nào để nhận tự động làm việc để xác minh maven khi persistence.xml nằm trong thư mục src/test không?

persistence.xml:

<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="1.0"> 

    <persistence-unit name="Unit" transaction-type="RESOURCE_LOCAL"> 
    <properties> 
     <!-- Scan for annotated classes and Hibernate mapping XML files --> 
     <property name="hibernate.archive.autodetection" value="class" /> 
    </properties> 
    </persistence-unit> 

</persistence>

Theo mặc định dò ​​làm việc cho các đơn vị trong mục classpath giống như persistence.xml. Nó có thể được cấu hình bởi các yếu tố <jar-file>.

Để kích hoạt dò chính xác khi persistence.xml là trong src/test/resources/META-INF tôi sử dụng cách lừa sau:

persistence.xml:

<persistence ...> 
    <persistence-unit ...> 
     <jar-file>${project.build.outputDirectory}</jar-file> 
     ... 
    </persistence-unit> 
</persistence> 

pom.xml - cho phép lọc nguồn cho src/test/resources:

<project ...> 
    ... 
    <build> 
     <testResources> 
      <testResource> 
       <directory>src/test/resources</directory> 
       <filtering>true</filtering> 
      </testResource> 
     </testResources> 
    </build> 
</project> 

Mặc dù tôi' m không chắc chắn làm thế nào để sử dụng nó nếu persistence.xml của bạn thực sự là tôi n src/test/META-INF.

Nếu bạn sử dụng Spring Framework bạn có thể làm như sau với một PersistenceUnitPostProcessor

CustomPersistenceUnitPostProcessor:

package com.yourpackage.utils.jpa.CustomPersistenceUnitPostProcessor; 

    import java.util.HashSet; 
    import java.util.List; 
    import java.util.Set; 
    import javax.persistence.Entity; 
    import net.sourceforge.stripes.util.ResolverUtil; 
    import org.slf4j.Logger; 
    import org.slf4j.LoggerFactory; 
    import org.springframework.beans.factory.InitializingBean; 
    import org.springframework.orm.jpa.persistenceunit.MutablePersistenceUnitInfo; 
    import org.springframework.orm.jpa.persistenceunit.PersistenceUnitPostProcessor; 

    /** 
    * This PersistenceUnitPostProcessor is used to search given package list for JPA 
    * entities and add them as managed entities. By default the JPA engine searches 
    * for persistent classes only in the same class-path of the location of the 
    * persistence.xml file. When running unit tests the entities end up in test-classes 
    * folder which does not get scanned. To avoid specifying each entity in the persistence.xml 
    * file to scan, this post processor automatically adds the entities for you. 
    * 
    */ 
    public class CustomPersistenceUnitPostProcessor implements PersistenceUnitPostProcessor, InitializingBean { 

     private static final Logger log = LoggerFactory.getLogger(CustomPersistenceUnitPostProcessor.class); 

     /** the path of packages to search for persistent classes (e.g. org.springframework). Subpackages will be visited, too */ 
     private List<String> packages; 

     /** the calculated list of additional persistent classes */ 
     private Set<Class<? extends Object>> persistentClasses; 

     /** 
     * Looks for any persistent class in the class-path under the specified packages 
     */ 
     @Override 
     public void afterPropertiesSet() throws Exception { 
      if (packages == null || packages.isEmpty()) 
       throw new IllegalArgumentException("packages property must be set"); 
      log.debug("Looking for @Entity in " + packages); 
      persistentClasses = new HashSet<Class<? extends Object>>(); 
      for (String p : packages) { 
       ResolverUtil<Object> resolver = new ResolverUtil<Object>(); 
       ClassLoader cl = this.getClass().getClassLoader(); 
       log.debug("Using classloader: " + cl); 
       resolver.setClassLoader(cl); 
       resolver.findAnnotated(Entity.class, p); 
       Set<Class<? extends Object>> classes = resolver.getClasses(); 
       log.debug("Annotated classes: " + classes); 
       persistentClasses.addAll(classes); 
      } 
      if (persistentClasses.isEmpty()) 
       throw new IllegalArgumentException("No class annotated with @Entity found in: " + packages); 
     } 

     /** 
     * Add all the persistent classes found to the PersistentUnit 
     */ 
     @Override 
     public void postProcessPersistenceUnitInfo(MutablePersistenceUnitInfo persistenceUnitInfo) { 
      for (Class<? extends Object> c : persistentClasses) 
       persistenceUnitInfo.addManagedClassName(c.getName()); 
     } 

     public void setPackages(List<String> packages) { 
      this.packages = packages; 
     } 
    } 

Xuân Config:

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> 
    <property name="persistenceUnitName" value="thePersistenceUnitName" />

        </list> 
       </property> 
      </bean> 
     </list>
