struts2文件上传

Question

struts2在做文件上传是，当超过限制的上传文件总大小时，直接与服务器断开连接了，后台也没有报错，怎么回事啊？tomcat7.0的服务器，6.0试了也是这样。

package com.eg.action;

import java.io.File;
import java.io.IOException;
import java.util.List;

import org.apache.commons.io.FileUtils;
import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;

public class FileuploadAction extends ActionSupport {

	private List<File> upload;
	private List<String> uploadContentType;
	private List<String> uploadFileName;

	public List<File> getUpload() {
		return upload;
	}

	public void setUpload(List<File> upload) {
		this.upload = upload;
	}

	public List<String> getUploadContentType() {
		return uploadContentType;
	}

	public void setUploadContentType(List<String> uploadContentType) {
		this.uploadContentType = uploadContentType;
	}

	public List<String> getUploadFileName() {
		return uploadFileName;
	}

	public void setUploadFileName(List<String> uploadFileName) {
		this.uploadFileName = uploadFileName;
	}

	@Override
	public String execute()  {
		for (int i = 0; i <upload.size(); i++) {
		System.out.println("上传的文件类型：" + uploadContentType.get(i));
		System.out.println("上传的文件名：" + uploadFileName.get(i));
		 try {
			FileUtils.copyFile(upload.get(i), new File(ServletActionContext
			 .getServletContext().getRealPath("/WEB-INF/uploads"),
			 uploadFileName.get(i)));
		} catch (IOException e) {
			e.printStackTrace();
			throw new RuntimeException(e);
		}
		}
		return null;
	}
}

Answer 1

设置大一点然后日志级别调debug

Answer 2

回复
我记得tomcat的配置里面好像有最大上传文件大小还是连接超时时间，设置下这个就行了

Answer 3

springmvc劝降师还有30秒到达战场

Answer 4

试了，还是没有用哦，struts.xml 文件配置上传 文件总大小还是可以的！

Answer 5

xml配置里写的上限好象只管到2m 再大要写到 struts.properties 里面
