創建用戶pojo對象

這里直接實現SpringSecurity的用戶對象接口，并添加角色集合私有屬性。注意接口屬性都要標記不參與json的處理

@Data public class SysRole implements GrantedAuthority {private Integer id;private String roleName;private String roleDesc; }

創建角色pojo對象

這里直接使用SpringSecurity的角色規范，我們實現UserDetails的類型

@Data public class SysUser implements UserDetails {private Integer id;private String username;private String password;private Integer status;private List<SysRole> roles;@JsonIgnore@Overridepublic Collection<? extends GrantedAuthority> getAuthorities() {return roles;}@Overridepublic String getPassword() {return password;}@Overridepublic String getUsername() {return username;}@JsonIgnore@Overridepublic boolean isAccountNonExpired() {return true;}@JsonIgnore@Overridepublic boolean isAccountNonLocked() {return true;}@JsonIgnore@Overridepublic boolean isCredentialsNonExpired() {return true;}@JsonIgnore@Overridepublic boolean isEnabled() {return true;} }

提供角色mapper接口

public interface RoleMapper extends Mapper<SysRole> {@Select("SELECT r.id, r.role_name roleName, r.role_desc roleDesc " +"FROM sys_role r, sys_user_role ur " +"WHERE r.id=ur.rid AND ur.uid=#{uid}")public List<SysRole> findByUid(Integer uid); }

提供用戶mapper接口

這里就用到了Mybatis的一對多進行操作

public interface UserMapper extends Mapper<SysUser> {@Select("select * from sys_user where username = #{username}")@Results({@Result(id = true, property = "id", column = "id"),@Result(property = "roles", column = "id", javaType = List.class,many = @Many(select = "com.itheima.mapper.RoleMapper.findByUid"))})public SysUser findByName(String username); }

提供認證service接口

@Service @Transactional public class UserServiceImpl implements UserService {@Autowiredprivate UserMapper userMapper;@Overridepublic UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {return userMapper.findByUsername(s);} }
