Tomcat Spring引导FileNotFoundException而JSF fileUpload

Question

我正在尝试通过JSF 2.2 <h:inputFile>上传文件。当我在嵌入式Tomcat 8.0.23上运行我的代码时一切正常。当我尝试在独立的Tomcat 8.0.23上运行它并调用Part.getInputStream()捕获FileNotFoundException。

.xhtml：

    <h:form enctype="multipart/form-data" id="formId">
        <h:inputFile value="#{bean.file}" >           
    </h:form>

config .java：

@Configuration
public class JsfConfig implements ServletContextAware {

    @Bean
    public ServletRegistrationBean facesServletRegistration() {
        FacesServlet servlet = new FacesServlet();
        MultipartConfigElement multipartConfigElement = new MultipartConfigElement(null, 1024*1024*5, 1024*1024*20, 1024*1024*30);
        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(servlet, new String[] {"*.jsf", "*.xhtml"});
        servletRegistrationBean.setName("FacesServlet");
        servletRegistrationBean.setMultipartConfig(multipartConfigElement);
        servletRegistrationBean.setLoadOnStartup(1);
        return servletRegistrationBean;
    }
}

的.java：

private Part file; //get, set
private byte[] content; //get, set

public void save(){                
    content = getContentFromFile(file);
    //..
}

private byte[] getContentFromFile(Part file) {
    try {
        return IOUtils.toByteArray(file.getInputStream());
    } catch (IOException ex) {
        LOG.error("Read from file failed: " + ex);
        return null;
    }
} 

错误：

java.io.FileNotFoundException: /home/user01/apps/apache-tomcat-8.0.23/work/Catalina/localhost/app-web/upload_650b964a_0ff5_4c2f_8f95_07baba2cdc3b_00000121.tmp (No such file or directory)

更新 我在Windows和Linux上测试了这个错误。
