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

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。

其他回答

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> {

}

我正在使用spring boot 2.0，我通过用@EntityScan替换@ComponentScan来修复这个问题

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。

如果您正在使用多模块spring数据jpa项目。

如果您正在处理多个模块，并且它们有Jpa实体和存储库。这可能对你有用。我曾经在外部tomcat上部署时得到一个“Not a managed type”错误(在嵌入式tomcat中从未遇到过)。

我有一个主模块和另外两个依赖模块。当将主项目部署为war时，我可以看到总共有3个Spring应用程序正在初始化。当执行顺序是Main模块先执行，然后是子模块时，就不会出现错误。但有时，子模块通常在主模块之前被调用。这通常会导致“非托管类型实体异常”

棘手的是，错误不会出现在spring引导嵌入式tomcat中。但是当我们在外部tomcat中部署它时。这种例外过去来得太随意了。我必须多次部署相同的战争才能获得正确的命令。

I spent the whole day trying to solve the issue. But turned out the problem was with the way I added my other modules as a dependency in the Main module. If you are adding the spring boot module as a dependency in another project, make sure that the main class is not involved in the jar. When you have another spring boot project as a dependency and when you try to deploy the project as a war. The order of execution of the main application class is not guaranteed. Removing the main class will basically avoid the independent execution of child modules. Hence, there won't be any room for order of execution issue.

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。

    <bean id="entityManagerFactory"
