2,Dao

package org.catpro.dao;

import java.util.List;

import org.catpro.vo.Cat;

public interface CatDao {
List<Cat> searchCat();

int delete(String kinds);
}

3，DaoImpl

package org.catpro.dao.impl;


import java.sql.SQLException;
import java.sql.Statement;
import java.sql.Types;

import org.catpro.dao.CatDao;
import org.catpro.dao.conn.ConnectionPool;
import org.catpro.vo.Cat;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.support.JdbcDaoSupport;

public class CatDaoImpl extends JdbcDaoSupport implements CatDao {

   /**
* Dao 根据种类删除信息
*/

   int result = 0;
   String sql = "delete from cat where kinds=?";

   int[] types=new int[]{Types.VARCHAR};
   this.jdbcTemplate=this.getJdbcTemplate();
   result=this.jdbcTemplate.update(sql,parameValues,types);
   return result;
}

}

4,单元测试

package org.catpro.dao.test;

import org.catpro.dao.CatDao;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import junit.framework.TestCase;

public class CatDaoTest extends TestCase {
private ApplicationContext context = null;
@Override
protected void setUp() throws Exception {
   super.setUp();
   context=new ClassPathXmlApplicationContext("org/catpro/dao/config/dao-config.xml");
}
public void testDelete(){
   CatDao catDao=(CatDao)context.getBean("catDao");
   int result=catDao.delete("中国");
   assertTrue(result>0);
}
}
