我已經將struts庫升級到最新版本2.5.10.1。錯誤InstantiatingNullHandler無法創建和/或將值設置回對象
當我試圖從JSP中設置一個對象時，出現以下錯誤。
ERROR InstantiatingNullHandler Could not create and/or set value back on to object

User.java
@Entity
@Table(name = "UserInfo")
public class User implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@Column(name = "UserID")
private String userID;
@Column(name = "Password")
private String password;
@Column(name = "Department")
private String department;
@Transient
private String designation;
.
.
.
.
.
@Transient
private Role[] roleList;
@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
@JoinColumn(name = "UserID", nullable = true, insertable = false, updatable = false)
private List<UserExtraInfo> userExtraInfoList;
.
.
Other Getter and setters
public List<UserExtraInfo> getUserExtraInfoList() {
return userExtraInfoList;
}
public void setUserExtraInfoList(List<UserExtraInfo> userExtraInfoList) {
this.userExtraInfoList = userExtraInfoList;
}
}
其實我不是從JSP設置任何vlaues到userExtraInfoList。
如果我刪除userExtraInfoList，那麼它可以工作，但它在後面的代碼中使用。你能幫忙解決這個問題嗎？
在JSP中我做下面的Ajax調用
function getReportingManagersList(){
var department = $('#department').val();
var designation = $('#designation').val();
$.ajax({
data:{'user.department':department,'user.designation':designation},
url:'getReportingManagersList',
datatype:'json',
success:function(json, textStatus){
.
.
.
},
error: function(xhr, textStatus, errorThrown) {
alert('error while getting reporting manager list' + errorThrown);
}
});
}
Action類
public class UserAction extends ActionSupport implements Preparable, ServletRequestAware, ServletResponseAware, ServletContextAware {
private static final Logger LOGGER = Logger.getLogger(UserAction.class);
private UserService userService;
private User user;
.
.
.
@Override
public void prepare() throws Exception {
super.prepare();
}
public void getReportingManagersList() throws Exception {
LOGGER.info("get reporting manager list for department : "
+ user.getDepartment() + " and designation : "
+ user.getDesignation());
try {
List<User> userList = userService.getUserList(user);
StringBuilder json = new StringBuilder("{");
if (!userList.isEmpty()) {
int index = 1;
for (User user : userList) {
json.append("'");
json.append(user.getUserID());
json.append("':'");
json.append(user.getUserName());
json.append("'");
if (index < userList.size()) {
json.append(",");
}
index++;
}
}
json.append("}");
streamJsonToClient(json.toString().replaceAll("'", String.valueOf('"')));
} catch (Exception e) {
LOGGER.error("Error", e);
throw (e);
}
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
.
.
}
