Question

我在我的项目中使用Spring 4.3和JPA。我使用java配置来配置Hibernate而不是XMl配置。但是当我正在编译时，会收到错误消息。请指导我解决这个问题。

以下是堆栈跟踪

JPA配置类

`@Configuration
@EnableTransactionManagement
@PropertySource(value = { "classpath:application/core-application.properties" })
public class JPAConfiguration {

    @Autowired
    private Environment environment;

    @Bean
    public DataSource dataSource(){
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName"));
        dataSource.setUrl(environment.getRequiredProperty("jdbc.url"));
        dataSource.setUsername(environment.getRequiredProperty("jdbc.username"));
        dataSource.setPassword(environment.getRequiredProperty("jdbc.password"));
        return dataSource;
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() throws NamingException {
        LocalContainerEntityManagerFactoryBean factoryBean = new LocalContainerEntityManagerFactoryBean();
        factoryBean.setDataSource(dataSource());
        factoryBean.setPackagesToScan(new String[] { "com.dak.school.model" });
        factoryBean.setJpaVendorAdapter(jpaVendorAdapter());
        factoryBean.setJpaProperties(jpaProperties());
        return factoryBean;
    }

    /*
    * Provider specific adapter.
    */
    @Bean
    public JpaVendorAdapter jpaVendorAdapter() {
        HibernateJpaVendorAdapter hibernateJpaVendorAdapter = new HibernateJpaVendorAdapter();
        return hibernateJpaVendorAdapter;
    }

    /*
     * Here you can specify any provider specific properties.
     */
    private Properties jpaProperties() {
        Properties properties = new Properties();
        properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect"));
        // properties.put("hibernate.hbm2ddl.auto", environment.getRequiredProperty("hibernate.hbm2ddl.auto"));
        properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql"));
        properties.put("hibernate.format_sql", environment.getRequiredProperty("hibernate.format_sql"));
        return properties;
    }

    @Bean
    @Autowired
    public PlatformTransactionManager transactionManager(EntityManagerFactory emf) {
        JpaTransactionManager txManager = new JpaTransactionManager();
        txManager.setEntityManagerFactory(emf);
        return txManager;
    }
} `

应用程序属性文件

> jdbc.driverClassName = com.mysql.jdbc.Driver jdbc.url =

> jdbc.password = admin123fg hibernate.dialect =
> org.hibernate.dialect.MySQL5Dialect hibernate.hbm2ddl.auto=create-drop

服务实施类

@Service
//@Transactional(propagation = Propagation.REQUIRED, readOnly = false)
@Transactional
public class UserServiceImpl implements UserService{

    @Autowired(required = false)
    private  UserDao userDao;

    @Override
    public void saveUser(final User user) {

        userDao.create(user);

    }
}

Dao实施班

@Repository
public class UserDaoImpl extends DaoImpl<User,Long> implements UserDao {

}

抽象Daoimpl类

public abstract class DaoImpl<T, PK extends Serializable> implements IDao<T, PK> {

  /* Persistence Entity class type. */
  protected Class<T> entityClass;

  /* Entity manager to perform DAO operations. */
  @PersistenceContext
  protected EntityManager entityManager;

  /**
   * Constructor
   */
  @SuppressWarnings("unchecked")
  public DaoImpl() {

    ParameterizedType genericSuperclass = (ParameterizedType) getClass().getGenericSuperclass();
    this.entityClass = (Class<T>) genericSuperclass.getActualTypeArguments()[0];
  }


  /*
   * (non-Javadoc)
   * 
   * @see com.fg.baking.core.dao.IDao#create(java.lang.Object)
   */
  public T create(T t) {

    this.entityManager.persist(t);
    return t;
  }


  /*

   * 
   * @see com.fg.baking.core.dao.IDao#read(java.io.Serializable)
   */
  public T read(PK id) {

    return this.entityManager.find(entityClass, id);
  }


  /*

  public T update(T t) {

    return this.entityManager.merge(t);
  }


  /*

  public void delete(T t) {

    t = this.entityManager.merge(t);
    this.entityManager.remove(t);
  }

Answer 1

用这个替换你的@Bean public JpaTransactionManager transactionManager() { JpaTransactionManager txManager = new JpaTransactionManager(); txManager.setDataSource(dataSource()); txManager.setEntityManagerFactory(entityManagerFactory().getObject()); return txManager; } bean：

open System
open Akka.Actor
open Akka.Configuration
open Akka.Remote
open Akka.FSharp

let system = System.create "system" (Configuration.defaultConfig())

type GreeterMsg =
    | Hello of string
    | Goodbye of string

let greeter = spawn system "greeter" <| fun mailbox ->
    let rec loop() = actor {
        let! msg = mailbox.Receive()

        match msg with
        | Hello name -> printf "Hello, %s!\n" name
        | Goodbye name -> printf "Goodbye, %s!\n" name

        return! loop()
    }
    loop()

这似乎与https://issues.jboss.org/browse/RESTEASY-1241类似。我通过将RESTEasy从3.0.10.Final升级到3.0.19.Final来解决我的问题。

Answer 3

在将现有的Spring应用程序（具有XML配置）迁移到springboot时，我遇到了类似的错误：

APPLICATION FAILED TO START

Description:

The bean 'org.springframework.transaction.config.internalTransactionalEventListenerFactory' could not be registered. A bean with that name has already been defined and overriding is dis
abled.

Action:

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

我通过从旧xml中删除几个重复的“ <tx:”配置来解决此问题。最初，我添加了属性spring.main.allow-bean-definition-overriding=true，该属性只会从控制台隐藏该错误。但这并不能解决潜在的问题。因此，删除重复的配置解决了我的问题。

internalTransactionalEventListenerFactory无法使用jpa查找错误
