Could not parse multipart servlet request; nested exception is java.io.IOException: The temporary upload location

 

spring-boot項目，生產環境運行一段時間后，上傳圖片報錯，如下：

threw exception [Request processing failed; nested exception is org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; nested exception is java.io.IOException: The temporary upload location [/tmp/tomcat.2982178524163133296.8080/work/Tomcat/localhost/ssc] is not valid] with root cause] |
java.io.IOException: The temporary upload location [/tmp/tomcat.2982178524163133296.8080/work/Tomcat/localhost/ssc] is not valid

 

解決方案：添加指定目錄

@Configuration
public class MultipartConfig {
    /**
     * 文件上傳臨時路徑
     */
    @Bean
    MultipartConfigElement multipartConfigElement() {
        MultipartConfigFactory factory = new MultipartConfigFactory();
        factory.setLocation("/data/dubbo/cache");
        return factory.createMultipartConfig();
    }

}
