Spring Bean創建異常

[英]Spring Bean Creation Exception

問題描述

要了解Spring真正存在的真正問題，需要對結構有充分的了解。 我在此問題上待了兩天，找不到任何解決方案。 在我的項目中，在構建時使用Hibernate會顯示以下錯誤消息：

有趣的是blogController，langServices和LangDao是相關的，但是它們與“ nc_alert_log”表無關。

郎道 

package com.ns.commerce.framework.lang.dao;
import org.hibernate.Criteria;
import org.hibernate.SessionFactory;
import org.hibernate.criterion.Restrictions;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Repository;
import com.ns.commerce.framework.lang.model.Lang;
import com.ns.commerce.framework.generic.dao.GenericDAOImpl;

@Repository("langDao")
public class LangDaoImpl extends GenericDAOImpl<Lang, Long> implements LangDao {

@Autowired
public LangDaoImpl(@Qualifier("sessionFactory") SessionFactory sessionFactory) {
    this.setSessionFactory(sessionFactory);
}

@Override
public Lang findByLocaleCode(String localeCode) {
    Criteria criteria = getCriteria();
    criteria.add(Restrictions.eq("localeCode", localeCode));        
    return findByCriteriaFirst(criteria);       
}

@Override
public Lang findBySubdomain(String subdomain) {
    Criteria criteria = getCriteria();
    criteria.add(Restrictions.eq("subdomain", subdomain));
    return findByCriteriaFirst(criteria);       
}

@Override
public Lang findDefaultLang() {
    Criteria criteria = getCriteria();
    criteria.add(Restrictions.eq("defaultFlag", true));
    return findByCriteriaFirst(criteria);       
}
}

AlertLog.Java模型 

    @Column(name="alerted", columnDefinition = "TINYINT(1) DEFAULT 0")
private int alerted;

在數據庫上：Alerted Column> TINYINT（1），默認值為0。

3 個解決方案

解決方案1
 1  2013-01-17 10:19:37

Wrong column type in db.nc_alert_log for column alerted.   
Found: bit, expected: TINYINT(1) DEFAULT 0

引起問題。 檢查數據庫中alerted列的類型，並確保在AlertLog.java中使用相同的AlertLog.java 。

解決方案2
 1  2013-01-17 10:21:11

nc_alert_log和LangDao沒有直接關系，但是LangDao和休眠的sessionFactory是直接相關的。 由於數據庫定義錯誤，因此無法創建sessionFactory。 錯誤表明數據庫中的列類型不是TINYINT，而是BIT（布爾值）。 這就是sessionFactory無法啟動的原因。 沒有sesionFactory，就不能創建LangDao等。

解決方案3

private int alerted;

嘗試更改為： 

private boolean alerted;
