Java 如何从jdbc用户服务获取用户信息

我正在使用spring安全授权，通过使用以下代码保护用户登录到我的应用程序：

<jdbc-user-service data-source-ref="dataSource" users-by-username-query="SELECT username, password as password,1 as enabled FROM users  WHERE username=?" authorities-by-username-query="SELECT username, authority,1 as enabled FROM users WHERE username =?" />

---

有没有办法将其他字段添加到此查询中，例如：ID、电子邮件

这仅用于身份验证，用户登录后，您可以通过以下方式检查登录用户：

@RequestMapping(path="loggedInUser", method={RequestMethod.GET}, produces={MediaType.APPLICATION_JSON_UTF8_VALUE})
    @ResponseBody
    public User getLoggedInUser(Principal principal) throws SQLException{
        return database.getUser(principal.getName());
    }

---

或者，如果要从数据库加载完整的自定义用户对象，然后在

SecurityContextHolder

/

会话中设置它，则可以使用自定义UserDetailService（）返回带有
principal.getName（）的用户名

创建自定义用户实体：
首先根据数据库表创建一个简单的自定义用户实体

@Entity
@Table(name = "users")
public class SecurityUser implements Serializable{  

    /**
     * 
     */
    private static final long serialVersionUID = 1L;

    @Id
    @Column(name = "username", nullable = false, unique = true)
    private String username;

    @Column(name = "password", nullable = false)
    @NotNull
    private String password;

    @Column(name = "type", nullable = false)
    @NotNull
    private String type;

    @Column(name = "full_name", nullable = false)
    @NotNull
    private String fullName;

    @Column(name = "email", nullable = false)
    @NotNull
    private String email;

    //Gettters & Setters plus Default constructor
}

创建用于从数据库访问上述用户的存储库/DAO
创建自定义用户详细信息服务
在配置中设置UserDetailService
在使用基于XML的配置时，请在配置文件中执行以下操作：

<bean id="myUserDetailsService"
  class="complete-path-to-serviceClasss.MyUserDetailsService"/>

<security:authentication-manager>
    <security:authentication-provider
      user-service-ref="myUserDetailsService" >
        <security:password-encoder ref="passwordEncoder">
        </security:password-encoder>
    </security:authentication-provider>
</security:authentication-manager>

public class CurrentUser extends User {
    /**
     * 
     */
    private static final long serialVersionUID = 1L;
    private SecurityUser securityUser;

    public CurrentUser(SecurityUser securityUser) {
        super(securityUser.getUsername(), securityUser.getPassword(), AuthorityUtils.createAuthorityList(securityUser.getRole().toString()));
        this.securityUser = securityUser;
    }

    public SecurityUser getSecurityUser() {
        return securityUser;
    }

    public String getRole() {
        return securityUser.getRole();
    }
}

@Service
public class CurrentUserDetailsService implements UserDetailsService {

    @Autowired
    private UserRepository userService;

    @Autowired
    public CurrentUserDetailsService(UserRepository userService) {
        this.userService = userService;
    }

    public CurrentUserDetailsService() {

    }

    @Override
    public CurrentUser loadUserByUsername(String username) throws UsernameNotFoundException, DataAccessException {
        SecurityUser user = userService.findByUsername(username);
        return new CurrentUser(user);
    }
}

<bean id="myUserDetailsService"
  class="complete-path-to-serviceClasss.MyUserDetailsService"/>

<security:authentication-manager>
    <security:authentication-provider
      user-service-ref="myUserDetailsService" >
        <security:password-encoder ref="passwordEncoder">
        </security:password-encoder>
    </security:authentication-provider>
</security:authentication-manager>

CurrentUser user = SecurityContextHolder.getContext().getAuthentication().getPrincipal()
