SpringBoot 02 shiro框架查询用户权限与角色

 实体类 

@Data
@AllArgsConstructor
@NoArgsConstructor
@TableName("t_user")
public class RUser {
    @TableId(value="id",type = IdType.AUTO)
    private Integer usrId;
    private String usrName;
    private  String usrAccount;
    private  String  usrPassword;
    private  String  usrSalt;
    private  String  usrClazz;

}

@AllArgsConstructor
@NoArgsConstructor
@Data
@TableName("t_role")
public class Role {
    @TableId(value="ro_id",type = IdType.AUTO) //告诉主键
    private Integer roId;//默认驼峰命名

    private String roLabel;

    @TableField(exist = false)
    private Set<Perm> permSet;

}

@AllArgsConstructor
@NoArgsConstructor
@Data
@TableName("t_perm")
public class Perm {
    @TableId(value="pm_id",type = IdType.AUTO)

}

Mapper

@Mapper
public interface RUserMapper extends BaseMapper<RUser> {
    List<RUser> selectListByAccount(String usrAccount);
}

@Mapper
public interface RoleMapper extends BaseMapper<Role> {//只有单表查询的方法,多表查询要自己写
    Role selectByLable(String roLabel);
}
