Spring + Spring数据提交器在未初始化的entityManagerFactory bean上出现错误

Question

我想使用对我的项目中的一些表进行审计，但是我得到了一些错误。我有两个春季启动项目，索赔和InsureConnect。InsureConnect是索赔中的依赖项。

索赔具有Spring数据提交器依赖关系

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-envers</artifactId>
    <version>2.6.4</version>
</dependency>

项目索赔中的JPA配置如下所示。我在索赔项目中有JPA存储库

@Configuration
@EnableJpaRepositories(entityManagerFactoryRef = "claimsTransEntityManagerFactory",
        transactionManagerRef = "claimsTransTransactionManager", basePackages={"com.metamorphosys.claims.jpa.transaction"})
public class ClaimsTransactionConfig {

    private static final Logger LOGGER =  LoggerFactory.getLogger(ClaimsTransactionConfig.class);
    
    @Bean
    PlatformTransactionManager claimsTransTransactionManager() {
        return new JpaTransactionManager(claimsTransEntityManagerFactory().getObject());
    }

    @Bean
    LocalContainerEntityManagerFactoryBean claimsTransEntityManagerFactory() {
    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
    //code...
    }

ClaimsApplication.java

@SpringBootApplication(scanBasePackages ={"com.metamorphosys"})
@EnableJpaRepositories(repositoryFactoryBeanClass = EnversRevisionRepositoryFactoryBean.class)
public class ClaimsApplication{
//code
}

对于InsureConnect项目，下面是transactionConfig.java。

@Configuration
public class TransactionConfig {

    private static final Logger LOGGER =  LoggerFactory.getLogger(TransactionConfig.class);
    
    @Bean
    @Primary
    PlatformTransactionManager transTransactionManager() {
        return new JpaTransactionManager(transEntityManagerFactory().getObject());
    }

    @Bean
    @Primary
    LocalContainerEntityManagerFactoryBean transEntityManagerFactory() {

        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        // code

}

InsureConnectApplication.java

@SpringBootApplication
@EnableAsync
@ImportResource({ "classpath*:config/*.xml" })
@EnableJpaRepositories(entityManagerFactoryRef = "transEntityManagerFactory",
transactionManagerRef = "transTransactionManager", basePackages={"com.metamorphosys.insureconnect.jpa.transaction"}
,repositoryFactoryBeanClass = BaseRepositoryFactoryBean.class)
public class InsureConnectApplication implements ApplicationContextAware {

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

Insureconnect不具有Spring依赖关系

现在，当我运行Claims时，TransactionConfig在insureConnect项目中的错误如下。

Cannot create inner bean '(inner bean)#64ba4522' of type [org.springframework.orm.jpa.SharedEntityManagerCreator] while setting bean property 'entityManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#64ba4522': Cannot resolve reference to bean 'transEntityManagerFactory' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transEntityManagerFactory' defined in class path resource [com/metamorphosys/insureconnect/dataobjects/transaction/TransactionConfig.class]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: javassist/bytecode/ClassFile

如果我移除Spring Envers依赖项，则该项目运行良好。

有人能帮我理解为什么在使用Envers时会出现错误吗？提前谢谢。

注-我使用的是2.6.4v的Spring-数据-envers。

我的申请也有类似的问题。最后，我将jpa初学者添加到我的pom中，然后我的应用程序开始工作：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

我认为这个启动程序加载了一些额外的内容，即没有/或加载。
