action如下:
public class UploadAction {
private File upload;// 封装上传文件
private String uploadContentType;// 封装上传文件的类型
private String uploadFileName;// 封装上传文件名的属性
private String uploadPath;// 封装上传文件在服务器中的路径,通过参数设置
private String result;// 封装处理结果的值
private String valiPdf;
public File getUpload() {
return upload;
}
public void setUpload(File upload) {
this.upload = upload;
}
public String getUploadContentType() {
return uploadContentType;
}
public void setUploadContentType(String uploadContentType) {
this.uploadContentType = uploadContentType;
}
public String getUploadFileName() {
return uploadFileName;
}
public void setUploadFileName(String uploadFileName) {
this.uploadFileName = uploadFileName;
}
public String getUploadPath() {
return uploadPath;
}
public void setUploadPath(String uploadPath) {
this.uploadPath = uploadPath;
}
public String getResult() {
return result;
}
public void setResult(String result) {
this.result = result;
}
public String getValiPdf() {
return valiPdf;
}
public void setValiPdf(String valiPdf) {
this.valiPdf = valiPdf;
}
public String execute() throws IOException,SQLException{
String fn = uploadPath + uploadFileName;
String classPath = this.getClass().getResource("").getPath();
String webPath = new File(new File(new File(new File(new File(classPath).getParent()).getParent()).getParent()).getParent()).getParent();
String webFn = webPath + "\\" + fn;
System.out.println(uploadFileName+"........................");
String[] strsplit = uploadFileName.split("\\.");
for(String str: strsplit){
System.out.println(str+"........................");
}
if(!("pdf".equalsIgnoreCase(strsplit[1]))){
valiPdf = "文档格式不对,应该为PDF格式文件";
return "fail";
}else{
if (new File(webFn).exists()) {
result = "该文件已存在";
} else {
Connection conn = null;
PreparedStatement ps = null;
conn = JDBCUtils.getConn();
ps = conn.prepareStatement("insert into address values(null,'"+fn+"')");
ps.executeUpdate();
JDBCUtils.close(conn, ps, null);
FileOutputStream fos = new FileOutputStream(webFn);
InputStream is = new FileInputStream(upload);
byte[] buffer = new byte[102400];
int count = 0;
while ((count = is.read(buffer)) > 0) {
fos.write(buffer, 0, count);
}
fos.close();
is.close();
result = "文件上传成功";
}
return "result";
}
}
}
struts.xml代码如下:
为什么去掉if语句
if(!("pdf".equalsIgnoreCase(strsplit[1]))){
valiPdf = "文档格式不对,应该为PDF格式文件";
return "fail";
数据就可以传进去,不去掉的话,就传不进去呀??
难道是错误的result标签不可以配吗
