Spring Data JPA Проблемы

Question

Привет всем первым один простите за мой плохой английский, Я использую Spring Framework и конфигурируется с аннотациями, но существует ошибка

это мой WebAppInitializer класс я, используя для DispatcherServlet

public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer { 

@Override 
protected Class<?>[] getRootConfigClasses() { 
    return new Class<?>[] {RootConfig.class}; 
} 

//Cofiguración especifica de clases 
@Override 
protected Class<?>[] getServletConfigClasses() { 
    return new Class<?>[] {WebConfig.class}; 
} 

/** 
* Mapeo de DispatcherSerbvlet 
* @return 
*/ 
@Override 
protected String[] getServletMappings() { 
    return new String[]{"/"}; 
} 
} 

этот класс Rootconfig для сканирования весной компоненты

@Configuration 
@ComponentScan(basePackages = {"com.factory.soft.web"}, 
      excludeFilters = { 
      @Filter(type=FilterType.ANNOTATION,value=EnableWebMvc.class)}) 
public class RootConfig {} 

И последний класс WebConfig

@Configuration 
@EnableWebMvc //Habilita SpringMVC 

@ComponentScan("com.factory.soft") 
public class WebConfig extends WebMvcConfigurerAdapter{ 
/** 
* El resolvedor de vistas de jsp 
* @return 
*/ 
@Bean 
public ViewResolver viewResolver(){ 
    InternalResourceViewResolver resolver = new InternalResourceViewResolver(); 
    resolver.setPrefix("/WEB-INF/views/"); 
    resolver.setSuffix(".jsp"); 
    resolver.setExposeContextBeansAsAttributes(true); 
    resolver.setViewClass(org.springframework.web.servlet.view.JstlView.class); 
    return resolver; 
} 
@Bean 
public PersistenceAnnotationBeanPostProcessor paPostProcessor() { 
    return new PersistenceAnnotationBeanPostProcessor(); 
} 
/** 
* Configure Static contentc handling 
* @param configurer 
*/ 
@Override 
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) { 
    configurer.enable(); 
}} 

для JPA coniguration

@Configuration 
@EnableJpaRepositories(basePackages="com.factory.soft.repository") 
public class JPAConfig { 

@Bean 
public DataSource dataSource(){ 
    DriverManagerDataSource dataSource = new DriverManagerDataSource(); 
    dataSource.setDriverClassName("com.mysql.jdbc.Driver"); 
    dataSource.setUrl("jdbc:mysql://localhost:3306/db"); 
    dataSource.setUsername("user"); 
    dataSource.setPassword("password"); 
    return null; 
} 

@Bean 
public PersistenceExceptionTranslationPostProcessor exceptionTranslation(){ 
    return new PersistenceExceptionTranslationPostProcessor(); 
} 

@Bean 
public LocalContainerEntityManagerFactoryBean entityManagerFactory(){ 
    LocalContainerEntityManagerFactoryBean emfb = new LocalContainerEntityManagerFactoryBean(); 
    emfb.setDataSource(dataSource()); 
    emfb.setPersistenceUnitName("SOFTPU"); 
    JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter(); 
    emfb.setJpaVendorAdapter(vendorAdapter); 
    emfb.setJpaProperties(additionalProperties()); 
    emfb.setPackagesToScan("com.factory.soft.domain"); 
    return emfb; 
} 

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

Properties additionalProperties() { 
    Properties properties = new Properties(); 
    properties.setProperty("hibernate.hbm2ddl.auto", "create-drop"); 
    properties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect"); 
    return properties; 
} 

@Bean 
public HibernateJpaVendorAdapter jpaVendorAdapter() { 
    HibernateJpaVendorAdapter adapter = new HibernateJpaVendorAdapter(); 
    adapter.setDatabase(Database.MYSQL); 
    adapter.setShowSql(true); 
    adapter.setGenerateDdl(true); 
    return adapter; 
}} 

Это ошибка трек NetBeans

Answer 1

Похоже, что вы нуждаетесь в следующих Jar (java.lang.ClassNotFoundException: org.aopalliance.aop.Advice):

aopalliance-1.0.jar

Загрузите вышеуказанный Jar с http://aopalliance.sourceforge.net/ и добавьте в папку lib вашего веб-приложения. В качестве альтернативы вы можете добавить следующие зависимости к pom.xml, если вы используете maven:

<dependency> 
    <groupId>aopalliance</groupId> 
    <artifactId>aopalliance</artifactId> 
    <version>1.0</version> 
</dependency> 

Answer 2

Две проблемы,

1.Add АОП связанных зависимостей в POM

2.You're возвращение dataSource в null в JPAConfig класс

@Bean 
public DataSource dataSource(){ 
    DriverManagerDataSource dataSource = new DriverManagerDataSource(); 
    dataSource.setDriverClassName("com.mysql.jdbc.Driver"); 
    dataSource.setUrl("jdbc:mysql://localhost:3306/db"); 
    dataSource.setUsername("user"); 
    dataSource.setPassword("password"); 
    return null; 
} 

изменить возвращаемое значение в dataSource
