Question

我有一个带有Hibernate 5.2.6和Spring数据Envers 1.0.5的Spring boot 1.4.2应用程序。我正在审核我的实体，并且审核记录保持正确。

我的应用程序配置类被注释为使用EnversRevisionRepositoryFactoryBean.class作为JPA存储库工厂。

应用程序配置

@Configuration
@EnableAutoConfiguration
@ComponentScan
@EnableJpaRepositories(repositoryFactoryBeanClass = EnversRevisionRepositoryFactoryBean.class)
@EnableTransactionManagement
public class ApplicationConfig {}

我正在尝试阅读经审核实体的修订版。实体存储库扩展了RevisionRepository。

实体模型

@Entity(name = "Base")
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name = "type", discriminatorType = DiscriminatorType.INTEGER)
@Table(name = "BASE")
@Audited
public abstract class Base {

  @Id
  @GeneratedValue(generator = "baseSeq", strategy = GenerationType.SEQUENCE)
  @SequenceGenerator(name = "baseSeq", sequenceName = "BASE_SEQ", allocationSize = 1)
  @Column(name = "id", updatable = false, nullable = false)
  private Long id;

  @Column(name = "name", nullable = false)
  private String name;

  @Column(name = "name", nullable = false)
  private long barId;

  public Long getId() {
    return id;
  }

  public void setId(Long id) {
    this.id = id;
  }

  public String getName() {
    return name;
  }

  public void setName(String name) {
    this.name = name;
  }

  public long getBarId() {
    return barId;
  }

  public void setBarId(long barId) {
    this.barId = barId;
  }

  public abstract String getType();

}

@Entity
@DiscriminatorValue("1")
@Audited
@NamedQueries({
    @NamedQuery(
        name = "Foo.findById",
        query = "select f from Base b where b.id = ?1"),
    @NamedQuery(
        name = "Foo.findByBarId",
        query = "select f from Base b where b.barId = ?1")})
public class Foo extends Base {
    private String type = "Foo";

    @Override
    public String getType() {
      return type;
    }
}

实体存储库

interface FooRepository extends JpaRepository<Foo, Long>,
    JpaSpecificationExecutor<Foo>, RevisionRepository<Foo, Long, Integer> {

  foo findById(Long Id);

  foo findByBarId(Long barId);

}

应用程序启动失败，因为PropertyReferenceException无法初始化存储库。

引起： org.springframework.data.mapping.PropertyReferenceException：没有找到类型为Foo的属性findRevisions！ at org.springframework.data.mapping.PropertyPath。（PropertyPath.java:77）在 org.springframework.data.mapping.PropertyPath.create（PropertyPath.java:329）在 org.springframework.data.mapping.PropertyPath.create（PropertyPath.java:309）在 org.springframework.data.mapping.PropertyPath.from（PropertyPath.java:272）在 org.springframework.data.mapping.PropertyPath.from（PropertyPath.java:243）在 org.springframework.data.repository.query.parser.Part。（Part.java:76）在 org.springframework.data.repository.query.parser.PartTree $ OrPart。（PartTree.java:235）在 org.springframework.data.repository.query.parser.PartTree $ Predicate.buildTree（PartTree.java:373）在 org.springframework.data.repository.query.parser.PartTree $谓词（PartTree.java:353）在 org.springframework.data.repository.query.parser.PartTree。（PartTree.java:84）在 org.springframework.data.jpa.repository.query.PartTreeJpaQuery。（PartTreeJpaQuery.java:63）在 org.springframework.data.jpa.repository.query.JpaQueryLookupStrategy $ CreateQueryLookupStrategy.resolveQuery（JpaQueryLookupStrategy.java:103）在 org.springframework.data.jpa.repository.query.JpaQueryLookupStrategy $ CreateIfNotFoundQueryLookupStrategy.resolveQuery（JpaQueryLookupStrategy.java:214）在 org.springframework.data.jpa.repository.query.JpaQueryLookupStrategy $ AbstractQueryLookupStrategy.resolveQuery（JpaQueryLookupStrategy.java:77）在 org.springframework.data.repository.core.support.RepositoryFactorySupport $ QueryExecutorMethodInterceptor。（RepositoryFactorySupport.java:435）在 org.springframework.data.repository.core.support.RepositoryFactorySupport.getRepository（RepositoryFactorySupport.java:220）在 org.springframework.data.repository.core.support.RepositoryFactoryBeanSupport.initAndReturn（RepositoryFactoryBeanSupport.java:266）在 org.springframework.data.repository.core.support.RepositoryFactoryBeanSupport.afterPropertiesSet（RepositoryFactoryBeanSupport.java:252）在 org.springframework.data.jpa.repository.support.JpaRepositoryFactoryBean.afterPropertiesSet（JpaRepositoryFactoryBean.java:92）在 org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods（AbstractAutowireCapableBeanFactory.java:1642）在 org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean（AbstractAutowireCapableBeanFactory.java:1579）

据我所知，这应该是开箱即用的。看起来存储库被绑定到与期望的不同的实现。有什么想法吗？

您需要向应用程序类添加属性@EnableJpaRepositories(repositoryFactoryBeanClass = EnversRevisionRepositoryFactoryBean.class)（使用@SpringBootApplication注释的类）
