二、项目介绍
项目描述：这是一个基于SpringBoot+Vue框架 开发的古建筑文化宣传交流系统。首先，这是一个前后端分离的项目，代码简洁规范，注释说明详细，易于理解和学习。其次，这项目功能丰富，具有一个古建筑文化宣传交流系统该有的所有功能。
项目功能：此项目分为两个 角色：普通用户 和管理员 。普通用户 有登录注册、浏览古建筑信息、点赞收藏和评论古建筑、发布动态、查看动态、点赞收藏和评论动态、查看公告信息、修改个人信息、管理个人收藏点赞的古建筑信息、管理个人收藏点赞的动态信息等等功能。管理员有登录、查看数据统计信息、管理所有用户信息、管理所有话题信息、管理所有评论信息、管理所有古建筑信息、管理所有帖子信息、管理所有公告信息等等功能。
应用技术：SpringBoot + Vue3.0 + MySQL + MyBatis + Redis + ElementUI-Plus + Vite
运行环境：IntelliJ IDEA2019.3.5 + MySQL5.7 + Redis5.0.5 + JDK1.8 + Maven3.6.3 + Node14.16.1 + Visual Studio Code（以上工具在项目压缩包中都自带）
三、运行截图
四、主要代码
1.保存古建筑信息
java
/**
* 保存古建筑信息
* @param buildingDTO
* @return
*/
@Override
public ResponseDTO<Boolean> saveBuilding(BuildingDTO buildingDTO) {
// 进行统一表单验证
CodeMsg validate = ValidateEntityUtil.validate(buildingDTO);
if (!validate.getCode().equals(CodeMsg.SUCCESS.getCode())) {
return ResponseDTO.errorByMsg(validate);
}
Building building = CopyUtil.copy(buildingDTO, Building.class);
if(CommonUtil.isEmpty(building.getId())) {
// 添加操作
building.setId(UuidUtil.getShortUuid());
batchInsertPicture(buildingDTO.getPhotoList(), building.getId());
if(buildingMapper.insertSelective(building) == 0) {
return ResponseDTO.errorByMsg(CodeMsg.BUILDING_ADD_ERROR);
}
} else {
// 修改操作
PictureExample pictureExample = new PictureExample();
pictureExample.createCriteria().andRefIdEqualTo(buildingDTO.getId());
pictureMapper.deleteByExample(pictureExample);
batchInsertPicture(buildingDTO.getPhotoList(), buildingDTO.getId());
if(buildingMapper.updateByPrimaryKeySelective(building) == 0) {
return ResponseDTO.errorByMsg(CodeMsg.BUILDING_EDIT_ERROR);
}
}
return ResponseDTO.successByMsg(true, "保存成功！");
}2.用户登录
java
/**
* 前台用户登录操作
* @param userDTO
* @return
*/
@Override
public ResponseDTO<UserDTO> homeLogin(UserDTO userDTO) {
// 进行是否为空判断
if(CommonUtil.isEmpty(userDTO.getPhone())){
return ResponseDTO.errorByMsg(CodeMsg.PHONE_EMPTY);
}
if(CommonUtil.isEmpty(userDTO.getPassword())){
return ResponseDTO.errorByMsg(CodeMsg.PASSWORD_EMPTY);
}
// 对比昵称和密码是否正确
UserExample userExample = new UserExample();
userExample.createCriteria()
.andPhoneEqualTo(userDTO.getPhone())
.andPasswordEqualTo(userDTO.getPassword());
List<User> userList = userMapper.selectByExample(userExample);
if(userList == null || userList.size() != 1){
return ResponseDTO.errorByMsg(CodeMsg.PHONE_PASSWORD_ERROR);
}
// 生成登录token并存入Redis中
UserDTO selectedUserDTO = CopyUtil.copy(userList.get(0), UserDTO.class);
String token = UuidUtil.getShortUuid();
selectedUserDTO.setToken(token);
//把token存入redis中 有效期1小时
stringRedisTemplate.opsForValue().set("USER_" + token, JSON.toJSONString(selectedUserDTO), 3600, TimeUnit.SECONDS);
return ResponseDTO.successByMsg(selectedUserDTO, "登录成功！");
}3.查询帖子信息
java
/**
* 获取帖子数据
* @param postDTO
* @return
*/
@Override
public ResponseDTO<List<PostDTO>> getPostList(PostDTO postDTO) {
PostExample postExample = new PostExample();
PostExample.Criteria criteria = postExample.createCriteria();
if(!CommonUtil.isEmpty(postDTO.getUserId())) {
criteria.andUserIdEqualTo(postDTO.getUserId());
}
if(!CommonUtil.isEmpty(postDTO.getId())) {
criteria.andIdEqualTo(postDTO.getId());
}
if(!CommonUtil.isEmpty(postDTO.getTopicId())) {
TopicItemExample topicItemExample = new TopicItemExample();
topicItemExample.createCriteria().andTopicIdEqualTo(postDTO.getTopicId());
List<String> postIdList = topicItemMapper.selectByExample(topicItemExample).stream().map(TopicItem::getPostId).collect(Collectors.toList());
if(postIdList.size() > 0) {
criteria.andIdIn(postIdList);
} else {
criteria.andIdEqualTo("-");
}
}
if(postDTO.getIdList() != null ) {
if(postDTO.getIdList().size() > 0) {
criteria.andIdIn(postDTO.getIdList());
} else {
criteria.andIdEqualTo("-");
}
}
postExample.setOrderByClause("create_time desc");
List<Post> postList = postMapper.selectByExample(postExample);
// 将domain类型数据 转成 DTO类型数据
List<PostDTO> postDTOList = CopyUtil.copyList(postList, PostDTO.class);
for(PostDTO post : postDTOList) {
// 获取关联图集信息
PictureExample pictureExample = new PictureExample();
pictureExample.createCriteria().andRefIdEqualTo(post.getId());
pictureExample.setOrderByClause("sort asc, id asc");
List<Picture> pictureList = pictureMapper.selectByExample(pictureExample);
List<String> photoList = pictureList.stream().map(Picture::getPhoto).collect(Collectors.toList());
post.setPhotoList(photoList);
// 获取关联话题数据
TopicItemExample topicItemExample = new TopicItemExample();
topicItemExample.createCriteria().andPostIdEqualTo(post.getId());
List<String> topicIdList = topicItemMapper.selectByExample(topicItemExample).stream().map(TopicItem::getTopicId).collect(Collectors.toList());
if(topicIdList.size() > 0) {
TopicExample topicExample = new TopicExample();
topicExample.createCriteria().andIdIn(topicIdList);
List<Topic> topicList = topicMapper.selectByExample(topicExample);
post.setTopicDTOList(CopyUtil.copyList(topicList, TopicDTO.class));
}
// 获取帖子关联用户信息
User user = userMapper.selectByPrimaryKey(post.getUserId());
post.setUserDTO(CopyUtil.copy(Optional.ofNullable(user).orElse(new User()), UserDTO.class));
// 判断用户是否收藏和点赞
if(!CommonUtil.isEmpty(postDTO.getToken())) {
ResponseDTO<UserDTO> loginUser = userService.getLoginUser(postDTO.getToken());
if(loginUser.getCode() == 0) {
UserDTO userDTO = loginUser.getData();
CollectExample collectExample = new CollectExample();
collectExample.createCriteria().andUserIdEqualTo(userDTO.getId()).andRefIdEqualTo(post.getId());
post.setCollect(collectMapper.countByExample(collectExample) != 0);
LikeExample likeExample = new LikeExample();
likeExample.createCriteria().andUserIdEqualTo(userDTO.getId()).andRefIdEqualTo(post.getId());
post.setLike(likeMapper.countByExample(likeExample) != 0);
}
}
}
return ResponseDTO.success(postDTOList);
}
