Spring Boot - 不是托管类型

Question

我使用 Spring boot+JPA 并在启动服务时遇到问题。

 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，DataSource 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());
    }

}

包如下，

1. Application 类在 - com.nervy.dialer
2. Datasource 班级在 - com.nervy.dialer.common
3. 实体类在 - com.nervy.dialer.domain
4. 服务等级在 com.nervy.dialer.domain.service.impl
5. 控制器在 - com.nervy.dialer.spring.controller
6. 存储库类在 - com.nervy.dialer.spring.jpa.repository
7. WebSecurityConfig 在 - com.nervy.dialer.spring.security

谢谢

Answer 1

我认为将 @ComponentScan 替换为 @ComponentScan("com.nervy.dialer.domain") 会起作用。

编辑 ：

我添加了一个 示例应用程序 来演示如何使用 BoneCP 设置池数据源连接。

该应用程序与您的应用程序具有相同的结构。我希望这将帮助您解决配置问题

Answer 2

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

2016 年 9 月更新：对于 Spring Boot 1.4+：

使用 org.springframework.boot.autoconfigure.domain.EntityScan

而不是 org.springframework.boot.orm.jpa.EntityScan ，因为 …boot.orm.jpa.EntityScan 自 Spring Boot 1.4 起已 弃用
