spring boot临时文件地址无效

spring boot上传文件出现错误：

org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; nested exception is java.io.IOException: The temporary upload location [/tmp/tomcat.2737591724424319502.8062/work/Tomcat/localhost/ROOT] is not valid

解决方法1：启动时增加参数

-Djava.io.tmpdir=/data/web/williamy/temp/usr/local/services/jdk1.8.0_91/bin/java -jar hq_demo-52.jar -Djava.io.tmpdir=/data/web/williamy/temp --spring.profiles.active=demo

解决方法2：提供文件上传临时路径

@Bean MultipartConfigElement multipartConfigElement() { MultipartConfigFactory factory = new MultipartConfigFactory(); factory.setLocation("/app/pttms/tmp"); return factory.createMultipartConfig(); }

解决方法3：修改application.properties

server.tomcat.basedir=${user.home}/deployer/tomcat
