今日完成

上午听老大讲PM和开发人员如何做好设计

编写Nginx日志脚本

# cat s.sh

#!/bin/bash 

#将1/June/2017全天的访问日志放到s.txt

cat access.log |sed -rn '/24\/June\/2017/p' > s.txt

#统计s.txt里面有多少个ip访问

cat a.txt |awk '{print $1}'|sort |uniq > ipnum.txt

#通过shell统计每个ip访问次数

for i in 'cat ipnum.txt'

do

iptj=`cat  access.log |grep $i | grep -v 400 |wc -l`

echo "ip地址"$i"在2017-06-01日全天(24小时)累计成功请求"$iptj"次，平均每分钟请求次数为："$(($iptj/1440)) >> result.txt

done

echo "其中20ms内的有：$num20"

num20= cat access.log |grep $i |awk '{print substr($2,4)' |awk '{if($l<0.020)print $l)' |wc -l

echo "其中10ms内的有: $num10"

num10= cat access.log |grep $i |awk '{print shustr($2,4)}' |awk '{if($l<0.10)print $l)' |wc -l

继续折腾Controller，Mybatis 逆向工程的方法先放一下。尝试网上搜到的Java.util.List方法

@RestController
public class StudentController {

    @Autowired
    StudentService studentService; //Service which will do all data retrieval/manipulation work

    // 显示所有学生
    @RequestMapping(value = "/student/", method = RequestMethod.GET)
    public ResponseEntity<List<EntryForm>> listAllEntryForms() {
        List<EntryForm> entryForms = studentService.findAllEntryForms();
        if (entryForms.isEmpty()) {
            return new ResponseEntity<List<EntryForm>>(HttpStatus.NO_CONTENT);
        }

        return new ResponseEntity<List<EntryForm>>(entryForms, HttpStatus.OK);
    }

//返回一个学生   

    @RequestMapping(value = "/student/{id}", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<EntryForm> getEntryForm(@PathVariable("id") long id) {
        System.out.println("通过id查找学生" + id);
        EntryForm entryForm = studentService.findById(id);
        if (entryForm == null) {
            System.out.println("学生id" + id + "未找到");
            return new ResponseEntity<EntryForm>(HttpStatus.NOT_FOUND);
        }
        return new ResponseEntity<EntryForm>(entryForm, HttpStatus.OK);
    }

//新建一个学生

    @RequestMapping(value = "/student/", method = RequestMethod.POST)
    public ResponseEntity<Void> createEntryForm(@RequestBody EntryForm entryForm, UriComponentsBuilder ucBuilder) {
        System.out.println("新建学生" + entryForm.getName());

        if (studentService.isEntryFormExist(entryForm)) {
            System.out.println("一个学生名叫" + entryForm.getName() + "已经存在");
            return new ResponseEntity<Void>(HttpStatus.CONFLICT);

            studentService.saveEntryForm(entryForm);

            HttpHeaders headers = new HttpHeaders();
            headers.setLocation(ucBuilder.path("/student/{id}").buildAndExpand(entryForm.getId()).toUri());
            return new ResponseEntity<Void>(headers, HttpStatus.CREATED);
        }
    }
}

//更新一个学生

@RequestMapping(value="/student/{id}", method = RequestMethod.PUT)
public ResponseEntity<EntryForm> updateEntryForm(@PathVariable Long id, @RequestBody EntryForm entryForm)
    throw Exception{
   System.out.println("更新学生" +id);

   EntryForm currentEntryForm = studentService.findById(id);

   if (currentEntryForm==null){
      System.out.println("学生id" +id+ "未找到");
      return new ResponseEntity<EntryForm>(HttpStatus.NOT_FOUND);
   }
   currentEntryForm.setCreateTime(entryForm.getCreateTime());
   currentEntryForm.setUpdateTime(entryForm.getUpdateTime());
   currentEntryForm.setName(entryForm.getName());
   currentEntryForm.setQq(entryForm.getQq());
   currentEntryForm.setMajor(entryForm.getMajor());
   currentEntryForm.setStartDate(entryForm.getStartDate());
   currentEntryForm.setSchool(entryForm.getSchool());
   currentEntryForm.setOnlineclass(entryForm.getOnlineclass());
   currentEntryForm.setOnlineno(entryForm.getOnlineno());
   currentEntryForm.setRecommender(entryForm.getRecommender());
   currentEntryForm.setCensor(entryForm.getCensor());

   studentService.updateEntryForm(currentEntryForm);
   return new ResponseEntity<EntryForm>(currentEntryForm, HttpStatus.OK);
}
//删除一个学生

   @RequestMapping(value="/student/{id}",method=RequestMethod.DELETE)
   public ResponseEntity<EntryForm> deleteEntryForm(@PathVariable("id")long id) {
   System.out.println("找到并删除学生id为"+id);

   EntryForm entryForm=studentService.findById(id);
   if (entryForm==null){
      System.out.println("无法删除。学生id为" +id+ "找不到");
       return new ResponseEntity<EntryForm>(HttpStatus.NOT_FOUND);
   }

     studentService.deleteEntryFormById(id);
    return new ResponseEntity<EntryForm>(HttpStatus.NO_CONTENT);
   }


//删除所有学生

@RequestMapping(value = "/student/",method=RequestMethod.DELETE)
public ResponseEntity<EntryForm>deleteAllEntryForms(){
        System.out.println("删除所有学生");

        studentService.deleteAllEntryForms();
        return new ResponseEntity<EntryForm>(HttpStatus.NO_CONTENT);
        }

        }

跑不通。。。。。。。。

范例是可以跑起来的，通过地址路径也能访问几个rest接口调出数据

试试减少字段，做个基础表用相同方法

遇到困难

windows环境下编写的txt文档是dos格式编码，直接丢到linux环境运行会报错

通过UltraEdit转换编码格式为unix可以解决问题

Controller层的编写问题，尝试减少字段数用简单表格看看

收获

简单Shell脚本编写

明日计划

Controller层的bug
