慕课网--Java开发企业级权限管理系统（五）

用户模块开发和部门模块开发涉及到的功能差不多，都是用户的增加，删除，修改，查找全部用户

SysUserService

public interface SysUserService {

    void save(UserParam param);

    void update(UserParam param);

    PageResult<SysUser> getPageByDeptId(int deptId, PageQuery page);

    List<SysUser> getAll();

    SysUser findByKeyword(String keyword);
}

SysUserServiceImpl

@Service
public class SysUserServiceImpl implements SysUserService {

    @Resource
    private SysUserMapper sysUserMapper;


    @Override

        BeanValidator.check(param);

        }
        String password = PasswordUtil.randomPassword();
