JavaSSH+mysql 不能实现抽象类
第一个问题: 项目有一个抽象类

Java code


package com.spm.dao;

import java.util.List;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.spm.model.Company;
/**
 * 公司抽象类
 * @author Administrator
 *
 */
public interface CompanyDao{
    
    @SuppressWarnings("unchecked")
    public List companyNameList(String compName);
    

    public Company companyId(Company company);
    
    
    public boolean companyAdd(Company company);

    public boolean companStopList(String listid);

    public boolean companUpdate(Company company);
    
    public boolean companDelete(Company company);

    public int companAll();
}






实现类

Java code

package com.spm.dao.impl;

import java.util.List;

import javax.management.Query;

import org.hibernate.Session;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.spm.dao.CompanyDao;
import com.spm.model.Company;
/**
 * 公司实现类
 * @author Administrator
 *
 */
public class CompanyDaoImpl extends HibernateDaoSupport implements CompanyDao  {
    
    public boolean companStopList(String listid) {
        // TODO Auto-generated method stub
        return false;
    }
    
    public boolean companUpdate(Company company) {
        // TODO Auto-generated method stub
        this.getHibernateTemplate().update(company);
        return false;
    }
    
    public boolean companyAdd(Company company) {
        
        System.out.println("添加公司xx");
        System.out.println(company.getCompFName()+company.getCompName());
        // TODO Auto-generated method stub
        try {
            this.getHibernateTemplate().save(company);
            return true;
        } catch (Exception e) {
            // TODO: handle exception
            e.printStackTrace();
            return false;
        }
    }
    
    
    public Company companyId(Company company) {
        // TODO Auto-generated method stub
        String Hql="from Company where compId=?";
        Object[] value={company.getCompId()};
        Company company2=(Company) this.getHibernateTemplate().find(Hql,value).get(0);
        return company2;
    }
    
    public List companyNameList(String compName) {
        // TODO Auto-generated method stub
        String hql="from Company where compFName like ? or compName like ?";
        //String hql="from Company where compFName like %"+compName+"% or compName like %"+compName+"%";
        org.hibernate.Query query =this.getSession().createQuery(hql);
        query.setString(0,"%"+compName+"%");
        query.setString(1,"%"+compName+"%");
        
        List list=query.list();
        return list;
    }
    /**
     * 刪除公司
     * @param company
     * @return
     */
    public boolean companDelete(Company company) {
        // TODO Auto-generated method stub
        System.out.println("删除公司xx");
        try {
            this.getHibernateTemplate().delete(company);
            return true;
        } catch (Exception e) {
            // TODO: handle exception
        }
        return false;
    }
    
    
    public List<Company> companPage(int pageNo,int pagesize){
        
        String Hql="from Company";
        Session session=this.getSession();
        List list =session.createQuery(Hql).setFirstResult((pageNo-1)*10).setMaxResults(pagesize).list();
        //this.getSession().close();
        session.close();

        return list;
    }
