private File test;  //临时文件，使命名要与jsp中file类型的input名称相同

private String testFileName; //文件名称

private String testContentType; //文件类型

public File getTest() {
return test;
}

public void setTest(File test) {
this.test = test;
}

public String getTestFileName() {
return testFileName;
}

public void setTestFileName(String testFileName) {
this.testFileName = testFileName;
}

public String getTestContentType() {
return testContentType;
}

public void setTestContentType(String testContentType) {
this.testContentType = testContentType;
}

@Override
public String execute() throws Exception {
System.out.println("文件名:"+this.testFileName+",文件类型："+this.testContentType);
File saveFile = new File("E:/"+this.testFileName);
FileUtils.copyFile(this.test, saveFile);
return SUCCESS;
}
