实际上，我正在为在线考试项目实施 Struts Spring & Hibernate Integration。但是当我在 JSP 页面中提交值时，它会抛出以下错误：

Struts 问题报告

我已附加 RegistrationAction.java 如下

注册动作.java

public class RegistrationAction extends ActionSupport {

    private UserRegistrationService userRegistrationService;

    public UserRegistrationService getUserRegistrationService() {
        return userRegistrationService;
    }

    public void setUserRegistrationService(
            UserRegistrationService userRegistrationService) {
        this.userRegistrationService = userRegistrationService;
    }

    private String first_Name;
    private String last_Name;
    private String emailid;
    private String passWord;
    private String Gender;
    private int dateofbirth;
    private int phoneNo;
    private float user_experience;

    @ManyToOne(fetch=FetchType.LAZY, targetEntity=UserDetails.class)
    @JoinColumn(name="user_id")
    private int user_id;
    private String addr_line1;
    private String addr_line2;
    private String addr_line3;
    private String city;
    private int zipcode;
    private String state;
    private String country;

    public RegistrationAction() {
    }

// generated getters and setters

    public String SaveUserDetails() {
        String forward = "SUCCESS";

        try {
            UserDetails s = new UserDetails();
            s.setFirst_name(getFirst_Name());
            s.setLast_name(getLast_Name());
            s.setEmail(getEmailid());
            s.setPassword(getPassWord());
            s.setGender(getGender());
            s.setDob(getDateofbirth());
            s.setPhone(getPhoneNo());
            s.setExperience(getUser_experience());

            Set<UserAddress> address = new HashSet<UserAddress>(0);
            setUserAddress(address);
            userRegistrationService.saveUserRegistration(s);

        } catch (Exception ex) {
            forward = "ERROR";
        }
        return forward;   }

    protected void setUserAddress(Set<UserAddress> address) throws Exception {
           UserAddress ad = new UserAddress();
           ad.setAddr_line1(getAddr_line1());
           ad.setAddr_line2(getAddr_line2());
           ad.setAddr_line3(getAddr_line3());
           ad.setCity(getCity());
           ad.setZipcode(getZipcode());
           ad.setState(getState());
           ad.setCountry(getCountry());

           address.add(ad); }
}

我不知道问题出在哪里。运行此程序时，它不会在 mysql 数据库中插入值...我对这个主题很陌生...请帮助我的朋友...无论如何提前感谢朋友...！！！

这是错误的：String forward = "SUCCESS";

正确的字符串是"success"；

String forward = "success";

而且，由于您正在扩展 ActionSupport，您可以使用常量 SUCCESS 来防止将来出现语法错误。

String forward = SUCCESS;

Struts.xml 中必须存在相同的映射。如果您在 Struts.xml 中添加“SUCCESS”，请去更改它，以防止将来出现头疼...

PS：与“错误”相同，应该是“错误”。
