设置用户的头像和修改密码功能

1.service层

UserService中添加updateHeader方法和changePassword方法。

        userMapper.updatePassword(id,CommunityUtil.md5(newPassword+user.getSalt()));
        return map;

}

2.修改配置文件

添加上传头像的路径及暴露头像Url地址的根地址：

# community
community.path.domain=http://localhost:8080
community.path.upload=d:/work/data/upload

3.controller层

在controller包中创建UserController类，代码见下。

package com.gerrrard.community.controller;

import com.gerrrard.community.entity.User;
import com.gerrrard.community.service.UserService;
import com.gerrrard.community.util.CommunityUtil;
import com.gerrrard.community.util.HostHolder;
import org.apache.commons.lang3.StringUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.multipart.MultipartFile;

import javax.servlet.http.HttpServletResponse;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.OutputStream;

@Controller
@RequestMapping("/user")
public class UserController {

    private static final Logger logger = LoggerFactory.getLogger(UserController.class);

    @Value("${community.path.upload}")
    private String uploadPath;

    @Value("${community.path.domain}")
    private String domain;

    @Value("${server.servlet.context-path}")
    private String contextPath;

    @Autowired
    private UserService userService;

    @Autowired
    private HostHolder hostHolder;

    @RequestMapping(path = "/setting", method = RequestMethod.GET)
    public String getSettingPage() {
        return "/site/setting";
    }

    @RequestMapping(path = "/upload", method = RequestMethod.POST)
    public String uploadHeader(MultipartFile headerImage, Model model) {
        if (headerImage == null) {
            model.addAttribute("error", "您还没有选择图片!");
            return "/site/setting";
        }

        String fileName = headerImage.getOriginalFilename();
        String suffix = fileName.substring(fileName.lastIndexOf("."));
        if (StringUtils.isBlank(suffix)) {
            model.addAttribute("error", "文件的格式不正确!");
            return "/site/setting";
        }

        // 生成随机文件名
        fileName = CommunityUtil.generateUUID() + suffix;
        // 确定文件存放的路径
        File dest = new File(uploadPath + "/" + fileName);
        try {
            // 存储文件
            headerImage.transferTo(dest);
        } catch (IOException e) {
            logger.error("上传文件失败: " + e.getMessage());
            throw new RuntimeException("上传文件失败,服务器发生异常!", e);
        }

        // 更新当前用户的头像的路径(web访问路径)
        // http://localhost:8080/community/user/header/xxx.png
        User user = hostHolder.getUser();
        String headerUrl = domain + contextPath + "/user/header/" + fileName;
        userService.updateHeader(user.getId(), headerUrl);

        return "redirect:/index";
    }

     //暴露一个访问接口给外部
    @RequestMapping(path = "/header/{fileName}", method = RequestMethod.GET)
    public void getHeader(@PathVariable("fileName") String fileName, HttpServletResponse response) {
        // 服务器存放路径
        fileName = uploadPath + "/" + fileName;
        // 文件后缀
        String suffix = fileName.substring(fileName.lastIndexOf("."));
        // 响应图片
        response.setContentType("image/" + suffix);
        try (
                FileInputStream fis = new FileInputStream(fileName);
                OutputStream os = response.getOutputStream();
        ) {
            byte[] buffer = new byte[1024];
            int b = 0;
            while ((b = fis.read(buffer)) != -1) {
                os.write(buffer, 0, b);
            }
        } catch (IOException e) {
            logger.error("读取头像失败: " + e.getMessage());
        }
    }
    
     @RequestMapping(path="/updatePassword",method = RequestMethod.POST)
    public String uploadPassword(String originPassword,String newPassword,String confirmPassword, Model model){

        Map<String,Object> map=userService.changePassword(hostHolder.getUser().getId(),originPassword,newPassword,confirmPassword);

        if(map==null || map.isEmpty()){
            model.addAttribute("msg","修改密码成功！");
            model.addAttribute("target","/index");
            return "/site/operate-result";
        }else {
            model.addAttribute("originPasswordMsg", map.get("originPasswordMsg"));
            model.addAttribute("newPasswordMsg", map.get("newPasswordMsg"));
            model.addAttribute("confirmPasswordMsg", map.get("confirmPasswordMsg"));
            return "/site/setting";
        }
    }
    
}

3.1更换头像

uoload方法：用户在setting页面点击上传头像按钮后，转到uploadHeader方法，先对输入进行合法性判断，包含判断用户是否选择图片，文件的格式正不正确，如果非法则转回setting页面；通过合法性判断后，生成随机文件名，再确定本地存放路径存储至本地；最后通过hostHolder获取到用户，确定“暴露用户头像的url地址”，并更新user MySQL的headerUrl字段，最后重定向至index页面。

getHeader方法：暴露headerUrl给外部，通过headerUrl即可访问到本地图片，即将本地图片地址映射为headerUrl地址。
