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

不要像我一样犯明显的错误，让模板类型的顺序不正确。确保你在模板声明中没有把id放在前面，比如:

public interface CapacityBasedProductRepository extends JpaRepository<Long, CapacityBasedProduct> {
}

JPA类是第一个，id列类型是第二个，如下所示:

public interface CapacityBasedProductRepository extends JpaRepository<CapacityBasedProduct, Long> {
}

否则，它会抱怨java.lang.Long是一个未知的实体类型。它使用第一项查找要使用的实体。

其他回答

在我的案例中，将package添加到@EntityScan并没有帮助，因为有一个工厂bean指定了包，所以必须在那里添加一个额外的条目。然后它开始工作了。

您可以使用@EntityScan注释，并提供用于扫描所有jpa实体的实体包。您可以在使用@SpringBootApplication注释的基应用程序类上使用此注释。

如。 @EntityScan(“com.test.springboot.demo.entity”)

在我的案例中，问题是由于我忘记用@javax.persistence注释我的Entity类。实体注释。哎!

//The class reported as "not a amanaged type"
@javax.persistence.Entity
public class MyEntityClass extends my.base.EntityClass {
    ....
}

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);

在我的例子中，我犯了一个错误，使用存储库类作为JpaRepository参数，而不是实体类。是这样的:

@Repository
public interface BuyerInspectionRepository extends JpaRepository<BuyerInspectionRepository,Long> {

}

所以我用实体类替换了存储库类。即买方检验。

@Repository
public interface BuyerInspectionRepository extends JpaRepository<BuyerInspection,Long> {

}
