原因

参考 [https://github.com/spring-projects/spring-boot/issues/5009][https_github.com_spring-projects_spring-boot_issues_5009]

`tmpwatch` – removes files which haven’t been accessed for a period of time

如上所言，删除指定的目录中一段时间未访问的文件。一般对于/tmp下的文件或日志文件

意思是tomcat的临时目录会被`tmpwatch`删除掉，甚至可能删除掉`class`文件，导致错误的发生

# 解决方法 #

## 方法1.启动时指定新的临时目录 ##

<table> 
 <tbody> 
  <tr> 
   <td> <pre>1
</pre> </td> 
   <td> <pre>-Djava.io.tmpdir=/var/tmp
</pre> </td> 
  </tr> 
 </tbody> 
</table>

## 方法2.配置文件中设置新的临时目录 ##

<table> 
 <tbody> 
  <tr> 
   <td> <pre>1
2
3
</pre> </td> 
   <td> <pre>server:
    tomcat:
       basedir: /var/tmp/
</pre> </td> 
  </tr> 
 </tbody> 
</table>

## 方法3.代码中配置tomcat 临时目录 ##

<table> 
 <tbody> 
  <tr> 
   <td> <pre>1
2
3
4
5
6
7
8
9
10
11
12
13
14
</pre> </td> 
   <td> <pre>@Configuration
public class MultipartConfig {
    @Bean
    MultipartConfigElement multipartConfigElement() {
        MultipartConfigFactory factory = new MultipartConfigFactory();
        String location = System.getProperty("user.dir") + "/data/tmp";
        File tmpFile = new File(location);
        if (!tmpFile.exists()) {
            tmpFile.mkdirs();
        }
        factory.setLocation(location);
        return factory.createMultipartConfig();
    }
}
</pre> </td> 
  </tr> 
 </tbody> 
</table>
