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.data.jpa.repository.support.JpaMetamodelEntityInformation.<init>(JpaMetamodelEntityInformation.java:68)

    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

对于未来的读者:

下面是用于扫描多个包的语法糖。

注意，我的两个包也在不同的jar中，但是包是主要的驱动程序。只是在记录我的两罐情况。

    em.setPackagesToScan(new String[] {"com.package.ONE.jpa.entities" , "com.package.TWO.jpa.entities"});

我原来的ERRANT代码如下:

    em.setPackagesToScan("com.package.ONE.jpa.entities, com.package.TWO.jpa.entities");

让我困惑的是我的“xml到java配置切换”。下面显示了一个简单的用逗号分隔的值。

逗号分隔的列表似乎适用于di.xml，但不适用于“java config”。

Java，它是:::"当它是逗号分隔，当它是字符串数组，当它是字符串变参数".......吉格锯拼图有时会把我逼疯。

其他回答

你要么错过了类定义上的@Entity，要么你有显式的组件扫描路径，而这个路径不包含你的类

我认为将@ComponentScan替换为@ComponentScan("com.nervy.dialer.domain")会有用。

编辑:

我已经添加了一个示例应用程序来演示如何使用BoneCP设置池化数据源连接。

该应用程序的结构与您的相同。我希望这将帮助您解决配置问题

你可以查一下java版本，我的问题改了版本就解决了。

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.7.1</version>
    <relativePath />
</parent>

我已经复制了类似的问题w/不是管理类型。

更具体地说:

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'stockPriceRepository' defined in com.example.stockclient.repository.StockPriceRepository defined in @EnableJpaRepositories declared on StockUiApplication: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class com.example.stockclient.StockPrice

由于我有多模块项目，我需要为Spring Data JPA启用自动配置支持，以了解JPA存储库的路径，因为默认情况下，它将只扫描主应用程序包及其子包来检测JPA存储库。

因此，在我的特定用例中，我已经使用@ enablejparepository来启用包含在必要包中的JPA存储库，但没有@EntityScan。

使用@EntityScan与使用@ enablejparepository情况相同，因为由于多模块项目，实体类没有放在主应用程序包中。

要了解更多细节，您可以参考这篇文章。

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 {

}
