今天完成的事情：（一定要写非常细致的内容，比如说学会了盒子模型，了解了Margin） 

今天改了很多接口，都是一点小问题，最坑的就是签到页面，到现在都没写出来。

package com.everest.academy.controller;

import com.everest.academy.business.vo.ResponseVo;
import com.everest.academy.service.SignService;
import com.everest.academy.util.ResultUtil;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.validation.constraints.Min;

/**
 * @ClassName SignController
 * @Description TODO
 * @Author 田野
 * @Data 15:23
 * @Version 1.0
 **/
@Slf4j
@RestController
@RequestMapping("/a/student/signing")
@Api(tags = "SignController", description = "学生签到")
public class SignController {
    @Autowired
    SignService signService;

    @ApiOperation(value = "首页点击签到", notes = "首页查看用户签到信息")
    @ApiImplicitParam(name = "id", value = "用户id", paramType = "path", required = true, dataType = "Integer")
    @GetMapping("{id}")
    public ResponseVo findGainState(@Min(value = 0, message = "参数不能小于0") @PathVariable("id") Integer id) throws Exception {
        return ResultUtil.success("查看用户签到信息成功" + signService.findSignById(id));
    }

package com.everest.academy.service.impl;

import com.everest.academy.business.dto.SignDto;
import com.everest.academy.framework.exception.ResourceIsNullException;
import com.everest.academy.persistence.mapper.UserMapper;
import com.everest.academy.persistence.mapper.UserSignMapper;
import com.everest.academy.service.SignService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;


/**
 * @ClassName SignServiceImpl
 * @Description 签到相关
 * @Author 田野
 * @Data 15:26
 * @Version 1.0
 **/
@Slf4j
@Service
public class SignServiceImpl implements SignService {
    @Autowired
    UserMapper userMapper;
    @Autowired
    UserSignMapper userSignMapper;

    @Override
    public SignDto findSignById(Integer id) throws ResourceIsNullException {
        SignDto signDto = userMapper.selectSignById(id);
        if (signDto == null) {
            throw new ResourceIsNullException("该用户不存在");
        }
        String signInRecord = signDto.getSignInRecord();
        long signInRecord1 = Long.parseLong(signInRecord);
        String i = Long.toBinaryString(signInRecord1);
        if(i.length()<31){
            int n=31-i.length();
            String temp="";
            for (int k=0;k<n;k++){
                temp=temp+"0";
            }
            i=i+temp;
        }
        signDto.setSignInRecord(i);
        return signDto;
    }

只写了一个接口，很烦。

明天计划的事情：跟前端一起改错，然后签到页面看能不能搞定吧。 
遇到的问题：心态有点崩，签到感觉之前想的全有问题。 
收获：知道修真院坑B贼多。
