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

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

从Spring boot 1.3迁移时遇到了一些问题。x到1.5,我得到了它的工作后更新实体包在EntityManagerFactory bean

  @Bean(name="entityManagerFactoryDef")
  @Primary
  public LocalContainerEntityManagerFactoryBean defaultEntityManager() {
      Map map = new HashMap();
      map.put("hibernate.default_schema", env.getProperty("spring.datasource.username"));
      map.put("hibernate.hbm2ddl.auto", env.getProperty("spring.jpa.hibernate.ddl-auto"));
      LocalContainerEntityManagerFactoryBean em = createEntityManagerFactoryBuilder(jpaVendorProperties())
              .dataSource(primaryDataSource()).persistenceUnit("default").properties(map).build();
      em.setPackagesToScan("com.simple.entity");
      em.afterPropertiesSet();
      return em;
  }

这个bean在应用程序类中引用如下

@SpringBootApplication
@EnableJpaRepositories(entityManagerFactoryRef = "entityManagerFactoryDef")
public class SimpleApp {

}

不要像我一样犯明显的错误,让模板类型的顺序不正确。确保你在模板声明中没有把id放在前面,比如:

public interface CapacityBasedProductRepository extends JpaRepository<Long, CapacityBasedProduct> {
}

JPA类是第一个,id列类型是第二个,如下所示:

public interface CapacityBasedProductRepository extends JpaRepository<CapacityBasedProduct, Long> {
}

否则,它会抱怨java.lang.Long是一个未知的实体类型。它使用第一项查找要使用的实体。

我在spring boot v1.3.x版本中遇到了同样的问题 我所做的就是将spring boot升级到1.5.7.RELEASE版本。然后问题就解决了。

下面对我有用。

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

import org.apache.catalina.security.SecurityConfig;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

import com.something.configuration.SomethingConfig;

@RunWith(SpringRunner.class)
@SpringBootTest(classes = { SomethingConfig.class, SecurityConfig.class }) //All your configuration classes
@EnableAutoConfiguration
@WebAppConfiguration // for MVC configuration
@EnableJpaRepositories("com.something.persistence.dataaccess")  //JPA repositories
@EntityScan("com.something.domain.entity.*")  //JPA entities
@ComponentScan("com.something.persistence.fixture") //any component classes you have
public class SomethingApplicationTest {

    @Autowired
    private WebApplicationContext ctx;
    private MockMvc mockMvc;

    @Before
    public void setUp() {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(ctx).build();
    }

    @Test
    public void loginTest() throws Exception {
        this.mockMvc.perform(get("/something/login"))
        .andDo(print()).andExpect(status().isOk());
    }

}

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);
