带有java抛出的Spring JPA EclipseLink配置无法执行异常转换

我正试图用java而不是XML来配置eclipselink和SpringJPA

这是我的配置文件

@Configuration
@EnableJpaRepositories
@EnableTransactionManagement
class ApplicationConfig {

@Bean
public DataSource dataSource() {

    BasicDataSource dataSource = new BasicDataSource();
    dataSource.setDriverClassName("com.mysql.jdbc.Driver");
    dataSource.setUrl("jdbc:mysql://localhost:3306/trail");
    dataSource.setUsername("user1");
    dataSource.setPassword("password");
    return dataSource;
}

@Bean
public EntityManagerFactory entityManagerFactory() {

    EclipseLinkJpaVendorAdapter vendorAdapter = new EclipseLinkJpaVendorAdapter();
    vendorAdapter.setGenerateDdl(true);

    LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
    factory.setJpaVendorAdapter(vendorAdapter);
    Map<String, String> jpaProperties = new HashMap<String, String>();
    jpaProperties.put("eclipselink.weaving", "false");
    jpaProperties.put("jpaDialect"," org.springframework.orm.jpa.vendor.EclipseLinkJpaDialect");
    factory.setJpaPropertyMap(jpaProperties);

    factory.setPackagesToScan("com.trail.jpatest");
    factory.setDataSource(dataSource());
    factory.setLoadTimeWeaver(new InstrumentationLoadTimeWeaver());
    factory.setJpaDialect(new EclipseLinkJpaDialect());

    factory.afterPropertiesSet();
    return factory.getObject();
}

@Bean
public PlatformTransactionManager transactionManager() {

    JpaTransactionManager txManager = new JpaTransactionManager();
    txManager.setEntityManagerFactory(entityManagerFactory());
    return txManager;
}
@Bean
public PersistenceExceptionTranslationPostProcessor persistenceExceptionTranslationPostProcessor(){
    return new PersistenceExceptionTranslationPostProcessor();
}
}

当我在Spring MVC中运行此代码时，我得到一个异常，

无法执行异常转换

请告诉我，我错过了什么

是我对添加持久性异常TranslationPostProcessor的理解 解决不了吗

在java中使用SpringJPA配置eclipselink是否有任何指针

我得到的例外是：
