                        <tr>    
                                <td>Key Skill In Field<br /></td>

                </table>
                </html:form> 

我的 ActionForm 是

包 com.hrstrides.employer.generateResume;

导入 org.apache.struts.upload.FormFile;

public classGenerateResumeForm扩展了org.apache.struts.action.ActionForm{

/**
 * 
 */
private static final long serialVersionUID = 6895513074470145219L;

private String designation;
private String experiance;
private String jobDesc;
private String currentSalary;
private String expectedSalary;  
private String readyToRelocate;
private String education;
private String keySkill;
private FormFile attachFile;
public String getDesignation() {
    return designation;
}
public void setDesignation(String designation) {
    this.designation = designation;
}
public String getExperiance() {
    return experiance;
}
public void setExperiance(String experiance) {
    this.experiance = experiance;
}
public String getJobDesc() {
    return jobDesc;
}
public void setJobDesc(String jobDesc) {
    this.jobDesc = jobDesc;
}
public String getCurrentSalary() {
    return currentSalary;
}
public void setCurrentSalary(String currentSalary) {
    this.currentSalary = currentSalary;
}
public String getExpectedSalary() {
    return expectedSalary;
}
public void setExpectedSalary(String expectedSalary) {
    this.expectedSalary = expectedSalary;
}
public String getReadyToRelocate() {
    return readyToRelocate;
}
public void setReadyToRelocate(String readyToRelocate) {
    this.readyToRelocate = readyToRelocate;
}
public String getEducation() {
    return education;
}
public void setEducation(String education) {
    this.education = education;
}
public String getKeySkill() {
    return keySkill;
}
public void setKeySkill(String keySkill) {
    this.keySkill = keySkill;
}
public FormFile getAttachFile() {
    return attachFile;
}
public void setAttachFile(FormFile attachFile) {
    this.attachFile = attachFile;
}
public String getCandidateName() {
    return candidateName;
}
public void setCandidateName(String candidateName) {
    this.candidateName = candidateName;
}
public static long getSerialversionuid() {
    return serialVersionUID;
}
private String candidateName;

}

，action类是

包com.hrstrides.employer.generateResume;

导入java.io.File； 导入 java.io.InputStream;

导入 javax.servlet.http.HttpServletRequest; 导入 javax.servlet.http.HttpServletResponse;

导入 org.apache.struts.action.Action; 导入 org.apache.struts.action.ActionForm; 导入 org.apache.struts.action.ActionForward; 导入 org.apache.struts.action.ActionMapping; 导入 org.apache.struts.upload.FormFile;

public classGenerateResumeActionextendsAction{

private String name;
private String designation;
private String experiance;
private String currentSalary;
private String expectedSalary;
private String relocate;
private String education;
private String keySkill;
private FormFile file;
private String jobDescription;

public ActionForward execute(ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse responese)throws Exception{

    GenerateResumeForm generateResume = (GenerateResumeForm) form;

    name = generateResume.getCandidateName();
    designation = generateResume.getDesignation();
    experiance = generateResume.getExperiance();
    currentSalary = generateResume.getCurrentSalary();
    expectedSalary = generateResume.getExpectedSalary();
    relocate = generateResume.getReadyToRelocate();
    education = generateResume.getEducation();
    keySkill = generateResume.getKeySkill();


    jobDescription = generateResume.getJobDesc();

//  FormFile myFile = generateResume.getAttachFile();
    //System.out.println(myFile.getFileSize());

    /*
    GenereateResumeDAO geneResume = new GenereateResumeDAO(name,designation,experiance,
            currentSalary,expectedSalary,relocate,education,keySkill,jobDescription);
    if (geneResume.isGenerated()){
        System.out.println("True");
    }else{
        System.out.println("False");
    }
    */
    return null;
}

}

和错误，如

在您的 html:form 标记中添加 enctype 属性，如下所示：

<html:form enctype="multipart/form-data"></html:form>
