Java SpringBoot2-jpa实体不是托管类型

我有一个标有

javax.persistence.Entity

的类，

SpringBoot

说它不是托管类型

课程安排如下

@Entity
@Table(name="users")
public class User {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;

private String name;

@Column(unique = true)
private String username;

...

UserRepository.java

public interface UserRepository extends CrudRepository<User, Long> {

    User findByUsername(String username);

    List<User> findByName(String name);

    @Query("UPDATE AppUser u SET u.lastLogin=:lastLogin WHERE u.username = ?#{ principal?.username }")
    @Modifying
    @Transactional
    public void updateLastLogin(@Param("lastLogin") Date lastLogin);

}

和SpringSecurityConfig.java

@Configuration
@EnableWebSecurity
@ComponentScan("com.bae.dbauth.security")
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private WebApplicationContext applicationContext;
    private CustomUserDetailsService userDetailsService;
    @Autowired
    private AuthenticationSuccessHandlerImpl successHandler;
    @Autowired
    private DataSource dataSource;

    @PostConstruct
    public void completeSetup() {
        userDetailsService = applicationContext.getBean(CustomUserDetailsService.class);
    }

    @Override
    protected void configure(final AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService)
            .passwordEncoder(encoder())
            .and()
            .authenticationProvider(authenticationProvider())
            .jdbcAuthentication()
            .dataSource(dataSource);
    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring()
        .antMatchers("/resources/**");
    }

    @Override
    protected void configure(final HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .antMatchers("/login")
            .permitAll()
            .and()
            .formLogin()
            .permitAll()
            .successHandler(successHandler)
            .and()
            .csrf()
            .disable();
    }

    ....

}

和应用程序类

@SpringBootApplication
@PropertySource("classpath:persistence-h2.properties")
@EnableJpaRepositories(basePackages = { "com.bae.dbauth.repositories" })
@EnableWebMvc
@Import(SpringSecurityConfig.class)
public class BaeDbauthApplication implements WebMvcConfigurer {

    @Autowired
    private Environment env;

    @Bean
    public DataSource dataSource() {
        final DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(env.getProperty("driverClassName"));
        dataSource.setUrl(env.getProperty("url"));
        dataSource.setUsername(env.getProperty("user"));
        dataSource.setPassword(env.getProperty("password"));
        return dataSource;
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        final LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
        em.setDataSource(dataSource());
        em.setPackagesToScan(new String[] { "com.bae.dbauth.models" });
        em.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
        em.setJpaProperties(additionalProperties());
        return em;
    }

    public static void main(String[] args) {
        SpringApplication.run(BaeDbauthApplication.class, args);
    }

}

当我运行应用程序时，会收到一条很长的错误消息，其中包括由以下原因引起的

：java.lang.IllegalArgumentException:非托管类型：class com.bae.dbauth.model.User

整个堆栈跟踪非常广泛，它从以下内容开始：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'springSecurityConfig': Unsatisfied dependency expressed through field 'successHandler'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'authenticationSuccessHandlerImpl': Unsatisfied dependency expressed through field 'userRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class com.bae.dbauth.model.User

我不明白用户类有什么问题

更新： 我在

SpringSecurityCongig.java

中添加/修改了注释，并尝试了

@Configuration
@EnableWebSecurity
@ComponentScan({"com.bae.dbauth.security", "com.bae.dbauth.model"})

及

其中

com.bae.dbauth.model

是

用户

实体所在的包，

com.bae.dbauth

是

SpringSecurityConfig.java

和主

应用程序

类所在的包

---

每种情况下的结果都是相同的-错误消息相同。

首先尝试在

User

中将

id

的类型更改为

Long

，而不是

Long

然后确保

@ComponentScan

还包括包含实体的java包。您可以指定多个要扫描的包，请参阅。E示例：

@ComponentScan({"pkg1","pkg2"})

---

在UserRepository中添加注释

@Repository

：

@Repository
public interface UserRepository extends CrudRepository<User, Long> {

     User findByUsername(String username);
     List<User> findByName(String name);
     @Query("UPDATE AppUser u SET u.lastLogin=:lastLogin WHERE u.username = ?#{ principal?.username }")

     @Modifying
     @Transactional
     public void updateLastLogin(@Param("lastLogin") Date lastLogin);
}

@存储库
公共接口UserRepository扩展了Crudepository{
用户findByUsername（字符串用户名）；
列出findByName（字符串名称）；
@查询（“更新AppUser u SET u.lastLogin=：lastLogin，其中u.username=？#{principal？.username}”）
@修改
@交易的
public void updateLastLogin（@Param（“lastLogin”）Date lastLogin）；
}

未找到实体。如果已自动配置entity manager Factory，则有2个选项：

• 添加@EntityScan
• 将实体放在应用程序下的包中（这些包按约定扫描）

我可以看到您自己配置了entity manager工厂

em.setPackagesToScan(new String[] { "com.bae.dbauth.models" });

当您的用户实体位于：

com.bae.dbauth.model

---

这让我觉得这只是一个输入错误。

完成，但仍然返回相同的错误消息。您的

用户

类和

应用程序

类的包名是什么？

@Repository
public interface UserRepository extends CrudRepository<User, Long> {

     User findByUsername(String username);
     List<User> findByName(String name);
     @Query("UPDATE AppUser u SET u.lastLogin=:lastLogin WHERE u.username = ?#{ principal?.username }")

     @Modifying
     @Transactional
     public void updateLastLogin(@Param("lastLogin") Date lastLogin);
}

em.setPackagesToScan(new String[] { "com.bae.dbauth.models" });
