实际上，我正在在线考试项目上实施Struts Spring和Hibernate集成。但是，当我在JSP页面中提交值时，它引发了以下错误：
支柱问题报告

我已将RegistrationAction.java附加如下
RegistrationAction.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 DB中插入值…对于该主题来说我是新手…请帮助我的朋友…无论如何都要感谢高级朋友… !!!
这是错误的： String forward = "SUCCESS";
String forward = "SUCCESS";
正确的字符串是 “成功” ；
String forward = "success";
并且，由于要扩展ActionSupport，因此可以使用常量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。如果在Struts.xml中放入“ SUCCESS”，请进行更改以防止将来出现麻烦…
PS：与“ ERROR”相同，应为“ error”。
