我的項目設置是Spring MVC的，Hibernate的3.2.x中，對MySQL數據庫org.hibernate.QueryParameterException：無法找到名爲參數
得到以下錯誤：
org.hibernate.QueryParameterException: could not locate named parameter email
方法1：
@Override
public Boolean isExist(String email) {
boolean flag = false;
String hql = "from com.cmgr.beans.UserAccount u where u.email = :email";
List<UserAccount> result = currentSession().createQuery(hql)
.setParameter("email", email)
.list();
UserAccount userAccount = (UserAccount)result.get(0);
if (userAccount!=null && userAccount.getEmail().equalsIgnoreCase(email)) {
flag = true;
}
return flag;
}
方法2：
@Override
public Boolean isExist(String email) {
boolean flag = false;
String hql = "from com.cmgr.beans.UserAccount u where u.email = :email";
List<UserAccount> result = currentSession().createQuery(hql).setString("email", email).list();
UserAccount userAccount = (UserAccount) result.get(0);
if (userAccount != null && userAccount.getEmail().equalsIgnoreCase(email)) {
flag = true;
}
return flag;
}
錯誤：
java.lang.IllegalArgumentException: Parameter email does not exist as a named parameter in [from com.cmgr.beans.UserAccount u where u.email = :email]

我也遇到了同樣的問題 - 徹底檢查日誌文件，您應該看到hibernate抱怨它沒有爲給定的實體bean找到有效的持久化上下文！ –
