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

别忘了加上 @ entity 关于域类

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

在Spring Version 6和JDK 17中，我得到了这个问题，当我使用jakarta.persist . entity时，我正在使用javax. persistence . entity，这个问题得到了解决

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”)

我得到这个错误是因为我愚蠢地写了

公共接口FooBarRepository扩展CrudRepository<FooBarRepository, Long>{…

A brief explanation: One typically creates a FooBarRepository class to manage FooBar objects (often representing data in a table called something like foo_bar.) When extending the CrudRepository to create the specialized repository class, one needs to specify the type that's being managed -- in this case, FooBar. What I mistakenly typed, though, was FooBarRepository rather than FooBar. FooBarRepository is not the type (the class) I'm trying to manage with the FooBarRepository. Therefore, the compiler issues this error.

我用粗体突出显示了输入错误的地方。在我的示例中删除突出显示的单词Repository，代码将被编译。

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。
