在Windows server下，跑了几个月的程序，突然报警了，我也很无语

 报警Unable to create tempDir. java.io.tmpdir is set to C:\Users\SRV-DA~1\AppData\Local\Temp\5\
SRV-DA~1为什么变成这样，我也不知道(就是当前用户名SRV-Data)
报警的意思就是临时路径找不到\temp\5\ 
2.解决方法
 
  在C盘找到对应位置。手动添加路径（不推荐） 
  指定一个路径，如下 
@Configuration(proxyBeanMethods = false)
public class MultipartConfig {
    @Bean
    MultipartConfigElement multipartConfigElement() {
        MultipartConfigFactory factory = new MultipartConfigFactory();
        // C:/Users/xxx/AppData/Local/Temp
        String location = System.getProperty("user.home") + "/AppData/Local/Temp";
        File tmpFile = new File(location);
        if (!tmpFile.exists()) {
            tmpFile.mkdirs();
        factory.setLocation(location);
        return factory.createMultipartConfig();
  重新指定java -Djava.io.tempdir=D:/tmpdir -jar xxxx.jar 
  修改tomcat临时存放文件位置(不推荐) 
//此方法会将所有tomcat的临时文件都放在指定目录，新目录没有定时清理功能，不建议
server.tomcat.basedir=xxxxxx
  修改VM定时清理功能（不建议) 
 查看了一下，用户名下面确实好多临时文件夹

                    Unable to create tempDir. java.io.tmpdir is set to C:\Users\SRV-DA~1\AppData\Local\Temp\5\在Windows server，跑了几个月的程序，突然报警了，我也很无语org.springframework.context.ApplicationContextException: Unable to start web server; nested exception is org.springframework.b
				因为未知原因，jdk-8u212-windows-x64.exe安装不上，拷贝别人安装好的文件夹C:\Program Files\Java\jdk1.8.0_231到自己的电脑，后端程序可以执行，但报以下错误信息：
Unable to create tempDir. java.io.tmpdir is set to C:\Users\ADMINI~1\AppData
解决办法：
删掉拷贝别人...
				偶然遇到，在此记录一下：Unable to create tempDir. java.io.tmpdir is set to C:\Windows\
背景：eclipse + jdk8
debug时会报错，但是能够通过run启动
百度了一些原因是项目路径中存在中文导致的乱码；但是我的项目路径没有中文
后来在论坛找到一个靠谱的回答（感谢）：
给java.io.tmpdir创造一个文件夹
步骤：window -> preferences -> java -> Installed J
无法创建 tempDir。 java.io.tmpdir 设置为 /tmp Unable to create tempDir. java.io.tmpdir is set to /tmp
解决方法：
第一种： 更改 /tmp目录 的权限以授予您的用户访问权限
# chmod -R 777 /tmp
第二种：将用户添加到sudo组
