本文介绍了无法创建类型为[org.springframework.orm.jpa.SharedEntityManagerCreator]的内部bean'(内部bean)'?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我使用了基于Java的配置.当我使用jpa信息库时，会得到can not create inner bean exception of type shared entity manger creator.
I have used the Java based configurations. When I use the jpa repositories I get the can not create inner bean exception of type shared entity manger creator.
Spring contex配置:
Spring contex config:
@Configuration
@ComponentScan(basePackages = { "com.sample.proj.controller" })
@EnableWebMvc
@EnableTransactionManagement
@EnableJpaRepositories("com.sample.proj.domain")
@PropertySource("classpath:application.properties")
public class ServletContextConfig {
private static final String PROPERTY_NAME_DATABASE_DRIVER = "db.driver";
private static final String PROPERTY_NAME_DATABASE_URL = "db.url";
private static final String PROPERTY_NAME_DATABASE_USERNAME = "db.username";
private static final String PROPERTY_NAME_DATABASE_PASSWORD = "db.password";
private static final String PROPERTY_NAME_HIBERNATE_DIALECT = "hibernate.dialect";
private static final String PROPERTY_NAME_HIBERNATE_FORMAT_SQL = "hibernate.format_sql";
private static final String PROPERTY_NAME_HIBERNATE_NAMING_STRATEGY = "hibernate.ejb.naming_strategy";
private static final String PROPERTY_NAME_HIBERNATE_SHOW_SQL = "hibernate.show_sql";
private static final String PROPERTY_NAME_HIBERNATE_HBN2DDL_SQL = "hibernate.hbm2ddl.auto";
@Resource
private Environment environment;
@Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(environment
.getRequiredProperty(PROPERTY_NAME_DATABASE_DRIVER));
dataSource.setUrl(environment
.getRequiredProperty(PROPERTY_NAME_DATABASE_URL));
dataSource.setUsername(environment
.getRequiredProperty(PROPERTY_NAME_DATABASE_USERNAME));
dataSource.setPassword(environment
.getRequiredProperty(PROPERTY_NAME_DATABASE_PASSWORD));
return dataSource;
}
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean()
throws Exception {
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setDataSource(dataSource());
entityManagerFactoryBean
.setPackagesToScan(new String[] { "com.sample.proj.domain" });
entityManagerFactoryBean
.setPersistenceProviderClass(HibernatePersistence.class);
Properties jproperties = new Properties();
jproperties.put("hibernate.dialect", environment
.getRequiredProperty(PROPERTY_NAME_HIBERNATE_DIALECT));
jproperties.put("hibernate.format_sql", environment
.getRequiredProperty(PROPERTY_NAME_HIBERNATE_FORMAT_SQL));
jproperties.put("hibernate.ejb.naming_strategy", environment
.getRequiredProperty(PROPERTY_NAME_HIBERNATE_NAMING_STRATEGY));
jproperties.put("hibernate.show_sql", environment
.getRequiredProperty(PROPERTY_NAME_HIBERNATE_SHOW_SQL));
jproperties.put("hibernate.hbm2ddl.auto", environment
.getRequiredProperty(PROPERTY_NAME_HIBERNATE_HBN2DDL_SQL));
JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
entityManagerFactoryBean.setJpaVendorAdapter(vendorAdapter);
entityManagerFactoryBean.setJpaProperties(jproperties);
return entityManagerFactoryBean;
}
}
Webintializer:
Webintializer:
@Override
public void onStartup(ServletContext container) {
// Create the 'root' Spring application context
AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
rootContext.register(ServletContextConfig.class);
// Manage the lifecycle of the root application context
container.addListener(new ContextLoaderListener(rootContext));
// Create the dispatcher servlet's Spring application context
AnnotationConfigWebApplicationContext dispatcherContext = new AnnotationConfigWebApplicationContext();
dispatcherContext.register(ServletContextConfig.class);
// Register and map the dispatcher servlet
ServletRegistration.Dynamic dispatcher = container.addServlet(
"dispatcher", new DispatcherServlet(dispatcherContext));
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/");
}
存储库:
public interface PersonRepository extends JpaRepository<Person, String> {
}
服务类别:
@Service
@Transactional
public class PersonService {
@Autowired
PersonRepository personRepository;
public Person saveDetails(Person person) {
// System.out.println("Service Class:Person Name:"+
// person.getPersonName());
System.out.println("Executed");
return person;
}
}
控制器类:
@RequestMapping(value = "/addPerson", method = RequestMethod.POST)
public String addperson(@RequestParam("personName") String name,
@RequestParam("personAddress") String address, Model model) {
System.out.println("Name:" + name);
System.out.println("Address:" + address);
Person person = new Person();
person.setPersonId(1);
person.setPersonName(name);
person.setPersonAddress(address);
personService.saveDetails(person);
model.addAttribute("result", "Your record inserted successfully");
return HOME_VIEW;
}
域类:
@Entity
@Table(name = "PERSON")
public class Person implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
@Id
private Integer personId;
private String personName;
private String personAddress;
//getters and setters...
}
异常堆栈跟踪如下:

推荐答案
首先，如果仔细查看异常跟踪，您会发现ContextLoaderListner实际上是在抱怨No bean named 'entityManagerFactory' is defined是没有被发现的根本原因能够创建personRepository.
First of all if you look closely at your exception trace you'll see that ContextLoaderListner is actually complaining about No bean named 'entityManagerFactory' is defined as the root cause for not being able to create personRepository.
由于我不知道确切的项目结构是什么，您可以尝试在LocalContainerEntityManagerFactoryBean中放入bean名称，以便Spring可以找到并注入它.
As I dont know what exact project structure is, You can try putting bean name with LocalContainerEntityManagerFactoryBean so that Spring can find and inject it.
即像这样的东西:
@Bean(name = "entityManagerFactoryBean")
public LocalContainerEntityManagerFactoryBean ...
