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

当前回答

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> {

}

其他回答

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);

我在用Kotlin做Spring web应用程序教程时，遇到了这个问题。在与官方GitHub存储库进行了一些比较后，我意识到我的错误:我的实体。Kt文件缺少它的包指令。所以我有以下(注意缺少包指令):

import com.example.blog.toSlug
import java.time.LocalDateTime
import javax.persistence.*

@Entity
class Article(
    var title: String,
    var headline: String,
    var content: String,
    @ManyToOne var author: User,
    var slug: String = title.toSlug(),
    var addedAt: LocalDateTime = LocalDateTime.now(),
    @Id @GeneratedValue var id: Long? = null)

@Entity
class User(
    var login: String,
    var firstname: String,
    var lastname: String,
    var description: String? = null,
    @Id @GeneratedValue var id: Long? = null)

而不是正确的

package com.example.blog

import java.time.LocalDateTime
import javax.persistence.*

@Entity
class Article(
    var title: String,
    var headline: String,
    var content: String,
    @ManyToOne var author: User,
    var slug: String = title.toSlug(),
    var addedAt: LocalDateTime = LocalDateTime.now(),
    @Id @GeneratedValue var id: Long? = null)

@Entity
class User(
    var login: String,
    var firstname: String,
    var lastname: String,
    var description: String? = null,
    @Id @GeneratedValue var id: Long? = null)

奇怪的是，我没有从IntelliJ得到任何警告。

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

多模块Maven项目

我知道@ entitscan之前被回答:

invzbl3 Manish Maheshwari

但我觉得有必要强调，在处理多模块Maven项目时，这个问题可能经常发生。

以我为例，我有一个多模块的Maven项目，其中一个模块是模型包，其他模块是微服务。在我的例子中，当我运行一个使用模型包中定义的类(在我的项目中调用的域)的微服务时，我必须将@EntityScan(basePackages = {"com.example.domain"})注释添加到@SpringBootApplication类:

@SpringBootApplication
@EnableEurekaClient
@EntityScan(basePackages = {"com.example.domain"}) // add this so the spring boot context knows where to look for entities
public class DoctorServiceApplication {

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

}
