Spring引导——不是托管类型

我使用Spring boot+JPA，在启动服务时遇到了一个问题。

Caused by: java.lang.IllegalArgumentException: Not an managed type: class com.nervytech.dialer.domain.PhoneSettings
    at org.hibernate.jpa.internal.metamodel.MetamodelImpl.managedType(MetamodelImpl.java:219)

    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1562)

这是Application.java文件，

@Configuration
@ComponentScan
@EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class })
@SpringBootApplication
public class DialerApplication {

    public static void main(String[] args) {
        SpringApplication.run(DialerApplication.class, args);
    }
}

我使用UCp进行连接池，数据源配置如下:

@Configuration
@ComponentScan
@EnableTransactionManagement
@EnableAutoConfiguration
@EnableJpaRepositories(entityManagerFactoryRef = "dialerEntityManagerFactory", transactionManagerRef = "dialerTransactionManager", basePackages = { "com.nervy.dialer.spring.jpa.repository" })
public class ApplicationDataSource {

    /** The Constant LOGGER. */
    private static final Logger LOGGER = LoggerFactory
            .getLogger(ApplicationDataSource.class);

    /** The Constant TEST_SQL. */
    private static final String TEST_SQL = "select 1 from dual";

    /** The pooled data source. */
    private PoolDataSource pooledDataSource;

UserDetailsService实现,

@Service("userDetailsService")
@SessionAttributes("user")
public class UserDetailsServiceImpl implements UserDetailsService {

    @Autowired
    private UserService userService;

服务层实现，

@Service
public class PhoneSettingsServiceImpl implements PhoneSettingsService {

}

存储库类，

@Repository
public interface PhoneSettingsRepository extends JpaRepository<PhoneSettings, Long> {

}

实体类,

@Entity
@Table(name = "phone_settings", catalog = "dialer")
public class PhoneSettings implements java.io.Serializable {

WebSecurityConfig类,

@Configuration
@EnableWebMvcSecurity
@ComponentScan
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private UserDetailsServiceImpl userDetailsService;

    /**
     * Instantiates a new web security config.
     */
    public WebSecurityConfig() {

        super();
    }

    /**
     * {@inheritDoc}
     * @see org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter#configure(org.springframework.security.config.annotation.web.builders.HttpSecurity)
     */
    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http.authorizeRequests()
            .antMatchers("/login", "/logoffUser", "/sessionExpired", "/error", "/unauth", "/redirect", "*support*").permitAll()
            .anyRequest().authenticated().and().rememberMe().and().httpBasic()
            .and()
            .csrf()
            .disable().logout().deleteCookies("JSESSIONID").logoutSuccessUrl("/logoff").invalidateHttpSession(true);
    }


    @Autowired
    public void configAuthentication(AuthenticationManagerBuilder auth) throws Exception {

      auth.userDetailsService(userDetailsService).passwordEncoder(new BCryptPasswordEncoder());
    }

}

包装如下:

应用程序类在- com. nerve .dialer中数据源类在- com. nerver .dialer.common中实体类在- com. nerver .dialer.domain 服务类在- com.nervy.dialer.domain.service.impl 控制器在- com.nervy.dialer.spring.controller 存储库类在- com.nervy.dialer.spring.jpa.repository中 WebSecurityConfig在- com.nervy.dialer.spring.security

谢谢

当前回答

如果你配置了你自己的EntityManagerFactory Bean，或者如果你从另一个项目复制粘贴了这样一个持久性配置，你必须在EntityManagerFactory的配置中设置或调整包:

@Bean
public EntityManagerFactory entityManagerFactory() throws PropertyVetoException {
    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
    vendorAdapter.setGenerateDdl(true);
    LocalContainerEntityManagerFactoryBean factory;
    factory = new LocalContainerEntityManagerFactoryBean();
    factory.setPackagesToScan("!!!!!!package.path.to.entities!!!!!");
    //...
}

注意“多重”需求，你需要一个String数组作为传递给setPackagesToScan的参数(而不是一个逗号分隔的单字符串值)。下面说明了这个问题。

    String[] packagesArray = "com.mypackage1,com.mypackage2".split(",");
    em.setPackagesToScan(packagesArray);

其他回答

在我的例子中，我错误地从jakarta.persistence-api导入类。

从javax.persistence导入。*为我工作过:

package foo;
import javax.persistence.Entity;

@Entity
@Table(name = "phone_settings", catalog = "dialer")
public class PhoneSettings implements java.io.Serializable {
   // ...
}

我想没有人提到，但值得注意的是，不是一个托管的类型错误也可能由包裹信件的情况。例如，如果要扫描的包被称为myEntities，而我们在包扫描配置中提供了myEntities，那么它可能在一台机器上工作，而在另一台机器上则不能工作，因此要小心大小写。

根据我的经验，您应该检查您的注释。如果将其用作bean，则必须使用@Component。但是作为存储库中的实体，您应该在类上面使用@Entity。

如果您正在使用SessionFactory作为EMF:

在我的例子中，问题是我忘记在Hibernate配置中包含一个带注释的类的新实体类型，为此我得到了错误。

所以，在你的SessionFactory bean中，不要忘记为你的新实体类型添加这一行:

configuration.addAnnotatedClass(MyEntity.class);

从Spring boot 1.3迁移时遇到了一些问题。x到1.5，我得到了它的工作后更新实体包在EntityManagerFactory bean

  @Bean(name="entityManagerFactoryDef")
  @Primary
  public LocalContainerEntityManagerFactoryBean defaultEntityManager() {
      Map map = new HashMap();
      map.put("hibernate.default_schema", env.getProperty("spring.datasource.username"));
      map.put("hibernate.hbm2ddl.auto", env.getProperty("spring.jpa.hibernate.ddl-auto"));
      LocalContainerEntityManagerFactoryBean em = createEntityManagerFactoryBuilder(jpaVendorProperties())
              .dataSource(primaryDataSource()).persistenceUnit("default").properties(map).build();
      em.setPackagesToScan("com.simple.entity");
      em.afterPropertiesSet();
      return em;
  }

这个bean在应用程序类中引用如下

@SpringBootApplication
@EnableJpaRepositories(entityManagerFactoryRef = "entityManagerFactoryDef")
public class SimpleApp {

}
