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

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);
    }

}

其他回答

在Spring Boot入口点类中使用@ entitscan配置实体的位置。

2016年9月更新:Spring Boot 1.4+: 使用org.springframework.boot.autoconfigure.domain.EntityScan 而不是org.springframework.boot.orm.jpa.EntityScan，作为…Boot .orm.jpa. entityscan在Spring Boot 1.4被弃用

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>

我能够通过在应用程序中添加以下内容来解决这个问题。属性文件。

spring.jpa.packagesToScan=你的实体文件夹的路径，比如com.java.entity

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。

    <!-- the value of "id" attribute below MUST BE "entityManagerFactory"  spring-data voodoo -->
    <bean id="entityManagerFactory"
          class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="packagesToScan" value="com.package.ONE.jpa.entities, com.package.TWO.jpa.entities"/>

                <property name="generateDdl" value="${spring.jpa.generate-ddl}"/>
            </bean>
        </property>

        </property>
    </bean>

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 {
    ....
}
