Vue3+java开发组队功能
创建用户可以创建一个队伍（一个房间队长），设置队伍人数，队伍名称（标题），描述，超时时间。 搜索 加入，用户可以加入未满的队伍（其他人，未满，未过期），是否需要队长同意 分享队伍，邀请人员 显示队伍人数 聊天 修改队伍信息 退出 解散 判断请求参数是否为空 是否登录，未登录直接跳转到登录，不允许创建 校验信息
队伍人数大于1小于20 队伍名称<=20 队伍人数<=412 是否公开（int）不穿默认位0，公开 如果是加密状态，一定3要有密码，且密码<=32 超时时间>当前时间 校验用户最多创建5个队伍 插入队伍信息到队伍表 插入用户 => 队伍关系到关系表 数据库表设计,队伍表，队伍用户表
create table team
(
id bigint auto_increment comment 'id'
primary key ,
name varchar ( 256 ) not null comment '队伍名称' ,
description varchar ( 1024 ) null comment '描述' ,
maxNum int default 1 not null comment '最大人数' ,
expireTime datetime null comment '过期时间' ,
userId bigint comment '用户id' ,
status int default 0 not null comment '0 - 公开，1 - 私有，2 - 加密' ,
password varchar ( 512 ) null comment '密码' ,
createTime datetime default CURRENT_TIMESTAMP null comment '创建时间' ,
updateTime datetime default CURRENT_TIMESTAMP null on update CURRENT_TIMESTAMP ,
isDelete tinyint default 0 not null comment '是否删除'
)
comment '队伍' ;
create table user_team
(
id bigint auto_increment comment 'id'
primary key ,
userId bigint comment '用户id' ,
teamId bigint comment '队伍id' ,
joinTime datetime null comment '加入时间' ,
createTime datetime default CURRENT_TIMESTAMP null comment '创建时间' ,
updateTime datetime default CURRENT_TIMESTAMP null on update CURRENT_TIMESTAMP ,
isDelete tinyint default 0 not null comment '是否删除'
)
comment '用户队伍关系' ;
使用mybatisX-generation插件自动生成实体类服务层，持久层代码 队伍基本增删改查代码编写
@RestController
@RequestMapping ( "/team" )
@CrossOrigin ( origins = { "http://localhost:5173" } , allowCredentials = "true" )
@Slf4j
public class TeamController {
@Resource
private UserService userService;
@Resource
private TeamService teamService;
@PostMapping ( "/add" )
public BaseResponse < Long > addTeam ( @RequestBody Team team) {
if ( team == null ) {
throw new BusinessException ( ErrorCode . PARAMS_ERROR ) ;
}
boolean save = teamService. save ( team) ;
if ( ! save) {
throw new BusinessException ( ErrorCode . SYSTEM_ERROR , "插入失败" ) ;
}
return ResultUtils . success ( team. getId ( ) ) ;
}
@PostMapping ( "/delete" )
public BaseResponse < Boolean > deleteTeam ( @RequestBody long id) {
if ( id <= 0 ) {
throw new BusinessException ( ErrorCode . PARAMS_ERROR ) ;
}
boolean result = teamService. removeById ( id) ;
if ( ! result) {
throw new BusinessException ( ErrorCode . SYSTEM_ERROR , "删除失败" ) ;
}
return ResultUtils . success ( true ) ;
}
@PostMapping ( "/delete" )
public BaseResponse < Boolean > updateTeam ( @RequestBody Team team) {
if ( team == null ) {
throw new BusinessException ( ErrorCode . PARAMS_ERROR ) ;
}
boolean result = teamService. updateById ( team) ;
if ( ! result) {
throw new BusinessException ( ErrorCode . SYSTEM_ERROR , "更新失败" ) ;
}
return ResultUtils . success ( true ) ;
}
@GetMapping ( "/delete" )
public BaseResponse < Team > getTeamById ( @RequestBody long id) {
if ( id <= 0 ) {
throw new BusinessException ( ErrorCode . PARAMS_ERROR ) ;
}
Team team = teamService. getById ( id) ;
if ( team == null ) {
throw new BusinessException ( ErrorCode . NULL_ERROR , "数据为空！" ) ;
}
return ResultUtils . success ( team) ;
}
}
查询队伍列表功能实现
新建TeamQuery业务请求参数封装类作为作为参数
实现查询队伍列表
@GetMapping ( "/list" )
public BaseResponse < List < Team > > listTeams ( TeamQuery teamQuery) {
if ( teamQuery == null ) {
throw new BusinessException ( ErrorCode . PARAMS_ERROR ) ;
}
Team team = new Team ( ) ;
BeanUtils . copyProperties ( team, teamQuery) ;
QueryWrapper < Team > = new QueryWrapper < > ( ) ;
List < Team > = teamService. list ( queryWrapper) ;
return ResultUtils . success ( teamList) ;
}
分页查询队伍列表功能实现
新建请求分页类
@Data
public class PageRequest implements Serializable {
private static final long serialVersionUID = - 9075033996918167511L ;
protected int pageSize;
protected int pageNum;
}
分页查询队伍实现代码
@GetMapping ( "/list/page" )
public BaseResponse < Page < Team > > listTeamsByPage ( TeamQuery teamQuery) {
if ( teamQuery == null ) {
throw new BusinessException ( ErrorCode . PARAMS_ERROR ) ;
}
Team team = new Team ( ) ;
BeanUtils . copyProperties ( team, teamQuery) ;
Page < Team > = new Page < > ( teamQuery. getPageNum ( ) , teamQuery. getPageSize ( ) ) ;
QueryWrapper < Team > = new QueryWrapper < > ( team) ;
Page < Team > Resultpage = teamService. page ( page, queryWrapper) ;
return ResultUtils . success ( Resultpage ) ;
}
使用Swagger+knif4j文档接口 创建队伍业务逻辑实现
@Service
public class TeamServiceImpl extends ServiceImpl < TeamMapper , Team > implements TeamService {
@Resource
private UserTeamService userTeamService;
@Override
@Transactional ( rollbackFor = Exception . class )
public long addTeam ( Team team, User loginUser) {
if ( team == null ) {
throw new BusinessException ( ErrorCode . PARAMS_ERROR ) ;
}
if ( loginUser == null ) {
throw new BusinessException ( ErrorCode . NO_AUTH ) ;
}
final long userId = loginUser. getId ( ) ;
int maxNum = Optional . ofNullable ( team. getMaxNum ( ) ) . orElse ( 0 ) ;
if ( maxNum < 1 || maxNum > 20 ) {
throw new BusinessException ( ErrorCode . PARAMS_ERROR , "队伍人数不满足要求" ) ;
}
String name = team. getName ( ) ;
if ( StringUtils . isBlank ( name) || name. length ( ) > 20 ) {
throw new BusinessException ( ErrorCode . PARAMS_ERROR , "队伍标题不满足要求" ) ;
}
String description = team. getDescription ( ) ;
if ( StringUtils . isNotBlank ( description) && description. length ( ) > 512 ) {
throw new BusinessException ( ErrorCode . PARAMS_ERROR , "队伍描述过长" ) ;
}
int status = Optional . ofNullable ( team. getStatus ( ) ) . orElse ( 0 ) ;
TeamStatusEnum statusEnum = TeamStatusEnum . getEnumByValue ( status) ;
if ( statusEnum == null ) {
throw new BusinessException ( ErrorCode . PARAMS_ERROR , "队伍状态不满足要求" ) ;
}
String password = team. getPassword ( ) ;
if ( TeamStatusEnum . SECRET . equals ( statusEnum) ) {
if ( StringUtils . isBlank ( password) || password. length ( ) > 32 ) {
throw new BusinessException ( ErrorCode . PARAMS_ERROR , "密码设置不正确" ) ;
}
}
Date expireTime = team. getExpireTime ( ) ;
if ( new Date ( ) . after ( expireTime) ) {
throw new BusinessException ( ErrorCode . PARAMS_ERROR , "超出时间 > 当前时间" ) ;
}
QueryWrapper < Team > = new QueryWrapper < > ( ) ;
queryWrapper. eq ( "userId" , userId) ;
long hasTeamNum = this . count ( queryWrapper) ;
if ( hasTeamNum >= 5 ) {
throw new BusinessException ( ErrorCode . PARAMS_ERROR , "用户最多创建5个队伍" ) ;
}
team. setId ( null ) ;
team. setUserId ( userId) ;
boolean result = this . save ( team) ;
Long teamId = team. getId ( ) ;
if ( ! result || teamId == null ) {
throw new BusinessException ( ErrorCode . PARAMS_ERROR , "创建队伍失败" ) ;
}
UserTeam userTeam = new UserTeam ( ) ;
userTeam. setUserId ( userId) ;
userTeam. setTeamId ( teamId) ;
userTeam. setJoinTime ( new Date ( ) ) ;
result = userTeamService. save ( userTeam) ;
if ( ! result) {
throw new BusinessException ( ErrorCode . PARAMS_ERROR , "创建队伍失败" ) ;
}
return teamId;
}
}
