jQuery에서 ajax 사용 시, json 처리 방법 (JAVA)

데이터가 배열인 경우..

-- JAVA

    StringBuffer sb = new StringBuffer();
    sb.append("[");
    for(Iterator<VO> it = listVo.iterator(); it.hasNext();) {
        VO vo = it.next();
        sb.append("[");
        sb.append("'"+vo.getCol1()+"',");
        sb.append("'"+vo.getCol2()+"',");
        sb.append("'"+vo.getCol3()+"',");
        sb.append("'"+vo.getCol4()+"'");
        sb.append("]");
        if(i++ < size-1) sb.append(",");
    }
    sb.append("]");
    response.setContentType("text/javascript");
    response.getWriter().print(sb.toString());
    response.getWriter().flush();
    return null;

-- JAVASCRIPT

success : function(transport) {

    var oJson = eval('(' + transport + ')');

}

데이터가 JSONObject일때

-- JAVA

    JSONObject outter = new JSONObject();

    outter.put("col1",value1);

    outter.put("col2",value2);

    outter.put("col3",value3);

    outter.put("col4",value4);

    response.setContentType("application/json; charset=UTF-8");

    PrintWriter pw = response.getWriter();

    pw.print(outter.toString());

    pw.flush();

    return null;

-- JAVASCRIPT

success : function(transport) {

    var oJson = transport;

}

배열과 JSONObject의 차이는..

[[value1, value2, value3],

 [value1, value2, value3],

 [value1, value2, value3],

 [value1, value2, value3]]

{"key1" : value1,

  "key2" : value2,

  "key3" : {"key3_1" : value3_1,

               "key3_2" : value3_2}

}

요렇게 생겨먹은게 다름..
