RowHandler的使用

实现一个filter,查询sex=1的所有记录。使用queryWithRowHandler()方法。  

FilterRowHandler.java  

package com.cs;

import java.util.ArrayList;
import java.util.List;

import com.ibatis.sqlmap.client.event.RowHandler;

public class FilterRowHandler implements RowHandler {

    private List<User> list = new ArrayList<User>();

    public void handleRow(Object obj) {
        User user = (User)obj;
        if(user.getSex()==1) {
            list.add(user);
        }
    }

    public List<User> getList() {
        return list;
    }
}

UserDaoImpl.java  

FilterRowHandler rh = new FilterRowHandler();
try {
    sqlmapper.queryWithRowHandler("selectAllUser", rh);
} catch (SQLException e) {
    e.printStackTrace();
}
List<User> list = rh.getList();
for(int i=0;i<list.size();i++) {
    System.out.println(list.get(i));
}
