最近开发了一个系统是用SpringBoot进行开发的，非常的不错。今天一生哥和大家分享一下。
希望一起交流学习哈！
一，简介
一个系统的开发需要经过以下步骤：
需求调研、需求分析、需求制定、系统开发、系统测试，最终才会走向市场！
今天开发了一个小系统，看完需求，我直接就进行了系统的开发。
当然系统前端的技术采用最主流的技术Vue。
二，?系统的界面介绍

三，系统核心代码介绍：
@PutMapping("/updatePassword")
public Result updatePassword(@RequestBody Account info, HttpServletRequest request) {
Account account = (Account) request.getSession().getAttribute("user");
if (account == null) {
return Result.error(ResultCode.USER_NOT_EXIST_ERROR.code, ResultCode.USER_NOT_EXIST_ERROR.msg);
}
//技术交流：javapandeng
String oldPassword = SecureUtil.md5(info.getPassword());
if (!oldPassword.equals(account.getPassword())) {
return Result.error(ResultCode.PARAM_PASSWORD_ERROR.code, ResultCode.PARAM_PASSWORD_ERROR.msg);
}
info.setPassword(SecureUtil.md5(info.getNewPassword()));
Integer level = account.getLevel();
if (1 == level) {
AdminInfo adminInfo = new AdminInfo();
BeanUtils.copyProperties(info, adminInfo);
adminInfoService.update(adminInfo);
}
if (2 == level) {
UserInfo userInfo = new UserInfo();
BeanUtils.copyProperties(info, userInfo);
userInfoService.update(userInfo);
}
info.setLevel(level);
info.setName(account.getName());
// 清空session，让用户重新登录
request.getSession().setAttribute("user", null);
return Result.success();
}
@PostMapping("/resetPassword")
public Result resetPassword(@RequestBody Account account) {
Integer level = account.getLevel();
if (1 == level) {
AdminInfo info = adminInfoService.findByUserName(account.getName());
if (info == null) {
return Result.error(ResultCode.USER_NOT_EXIST_ERROR.code, ResultCode.USER_NOT_EXIST_ERROR.msg);
}
info.setPassword(SecureUtil.md5("123456"));
adminInfoService.update(info);
}
if (2 == level) {
UserInfo info = userInfoService.findByUserName(account.getName());
if (info == null) {
return Result.error(ResultCode.USER_NOT_EXIST_ERROR.code, ResultCode.USER_NOT_EXIST_ERROR.msg);
}
info.setPassword(SecureUtil.md5("123456"));
userInfoService.update(info);
}
return Result.success();
}
private String getProperties(String key) {
Props props = new Props("classpath:config.properties", "UTF-8");
return props.getStr(key);
}
} @PutMapping
public Result update(@RequestBody FileInfo info, HttpServletRequest request) {
Account account = (Account) request.getSession().getAttribute("user");
if (!account.getLevel().equals(info.getLevel()) || !account.getId().equals(info.getUploadUserId())) {
return Result.error("1001", "不能修改他人的记录");
}
fileInfoService.update(info);
return Result.success();
}
//技术交流：javapandeng
@GetMapping("/{id}")
public Result<FileInfoVo> detail(@PathVariable Long id) {
FileInfoVo info = fileInfoService.findById(id);
return Result.success(info);
}
@GetMapping
public Result<List<FileInfoVo>> all() {
return Result.success(fileInfoService.findAll());
}
@GetMapping("/page/{name}")
public Result<PageInfo<FileInfoVo>> page(@PathVariable String name,
@RequestParam(defaultValue = "1") Integer pageNum,
@RequestParam(defaultValue = "5") Integer pageSize,
HttpServletRequest request) {
return Result.success(fileInfoService.findPage(name, pageNum, pageSize));
}
} /**
* 批量通过excel添加信息
* @param file excel文件
* @throws IOException
*/
@PostMapping("/upload")
public Result upload(MultipartFile file) throws IOException {
List<LinkInfo> infoList = ExcelUtil.getReader(file.getInputStream()).readAll(LinkInfo.class);
if (!CollectionUtil.isEmpty(infoList)) {
// 处理一下空数据
List<LinkInfo> resultList = infoList.stream().filter(x -> ObjectUtil.isNotEmpty(x.getName())).collect(Collectors.toList());
for (LinkInfo info : resultList) {
linkInfoService.add(info);
}
}
return Result.success();
}
@GetMapping("/getExcelModel")
public void getExcelModel(HttpServletResponse response) throws IOException {
// 1. 生成excel
Map<String, Object> row = new LinkedHashMap<>();
row.put("name", "百度");
row.put("url", "www.baidu.com");
List<Map<String, Object>> list = CollUtil.newArrayList(row);
// 2. 写excel
ExcelWriter writer = ExcelUtil.getWriter(true);
writer.write(list, true);
response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;charset=utf-8");
response.setHeader("Content-Disposition","attachment;filename=linkInfoModel.xlsx");
ServletOutputStream out = response.getOutputStream();
writer.flush(out, true);
writer.close();
IoUtil.close(System.out);
}四，系统数据库介绍：
系统的数据库采用的是Mysql，数据加密方式采用的是MD5，保证了系统的安全！
