2.action
private static final long serialVersionUID = 0x85369b8626L; private static final int BUFFER_SIZE = 16384; private File myFile; private File myFile1; private String fileName; private String fileName1; public void setMyFileFileName(String fileName) { this.fileName = fileName; } public void setMyFile(File myFile) { this.myFile = myFile; } public void setMyFile1FileName(String fileName) { this.fileName1 = fileName; } public void setMyFile1(File myFile1) { this.myFile1 = myFile1; }?
这样就可以获取到值了！
