在寫資料庫相關博文時，經常需要把結果集展示到頁面上。用圖片真的是太麻煩了，一篇文章都沒寫完我就已經忍無可忍了。
於是寫了一段程式碼來生成基礎的markdown格式表格程式碼。

import java.io.IOException;
import java.io.Reader;
import java.sql.SQLException;
import java.util.LinkedHashMap;
import java.util.List;

import com.ibatis.common.resources.Resources;
import com.ibatis.sqlmap.client.SqlMapClient;
import
 
 com.ibatis.sqlmap.client.SqlMapClientBuilder;

import connTest.conn.SqlmapFactory;
/**

 */
public class MarkDown {

    private static SqlMapClient client = null;
    private static String configFile = "config/SqlMapConfig.xml";
    private static Reader r = null;

    static
 
 {
        try {
            r = Resources.getResourceAsReader(configFile);
            client = SqlMapClientBuilder.buildSqlMapClient(r);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    /**
     * @param args
     * @throws SQLException 
     */
    public static
 
 void main(String[] args) throws SQLException {
        // TODO Auto-generated method stub
        List<LinkedHashMap> l2 = client.queryForList("blog.test");
        System.out.println("\r\r");
        prt(l2);
    }

    private static void prt(List<LinkedHashMap> list){
        if(list == null || list.size() == 0) return;
        LinkedHashMap temp = list.get(0);

        String str = "|";
        for(Object obj: temp.keySet()){
            str += obj + "|";
        }
        str += "\r|";
        for(Object obj: temp.keySet()){
            str += "----|";
        }

        for(LinkedHashMap tempMap: list){
            str += "\r|";
            for(Object obj: tempMap.keySet()){
                str += (tempMap.get(obj) == null ? "" : tempMap.get(obj)) + "|";
            }
        }

        System.out.println(str);
    }

}
