把Map 转化为query string

?

如何把Map转化为query string呢?

什么是query string?

即型如name=whuang&age=27

private String getRequestBodyFromMap(Map parametersMap,boolean isUrlEncoding/*,String charset*/) {
    	StringBuffer sbuffer = new StringBuffer();
    	for(Object obj:parametersMap.keySet()){
			String value=(String) parametersMap.get(obj);
			if(isUrlEncoding){
				try {
					value = URLEncoder.encode(value, SystemHWUtil.CHARSET_UTF);
					if(!ValueWidget.isNullOrEmpty(value)){
						parametersMap.put(obj, value);
					}
				} catch (UnsupportedEncodingException e1) {
					e1.printStackTrace();
				}
			}
			sbuffer.append(obj).append("=").append(value).append("&");
		}
		return sbuffer.toString().replaceAll("&$", SystemHWUtil.EMPTY);
    	
    }
    private StringBuffer getRequestBodyFromList(List<ParameterIncludeBean> parameters,boolean isUrlEncoding/*,String charset*/) {
        StringBuffer sbuffer = new StringBuffer();
        int size = parameters.size();
        for (int i = 0; i < size; i++) {
            ParameterIncludeBean parameterIncludeBean = parameters.get(i);
            if(parameterIncludeBean.isIgnore()){
            	parameters.remove(parameterIncludeBean);
            	size--;
            	i--;
            	continue;
            }
        	sbuffer.append(parameterIncludeBean.getQueryString(isUrlEncoding,urlEncodeParameterCharset));
            if (i < size - 1) {
                sbuffer.append("&");
            }
            
        }
        return sbuffer;
    }

表格执行完

parameterTable_1.setModel(model); 之后一定要render,即

/***
     * setCellEditor and setCellRenderer
     */
    public void rendTable(){
    	parameterTable_1.getColumnModel().getColumn(2)
		.setCellEditor(new MyButtonEditor());
    	parameterTable_1.getColumnModel().getColumn(2)
    	.setCellRenderer(new MyButtonRender());
    	if(AutoTestPanel.isTF_table_cell){//若表格的单元格是JTextField
    		parameterTable_1.getColumnModel().getColumn(0)
    		.setCellEditor(new MyTextFieldEditor());
        	parameterTable_1.getColumnModel().getColumn(0)
    		.setCellRenderer(new MyTextFieldRender());
        	parameterTable_1.getColumnModel().getColumn(1)
    		.setCellEditor(new MyTextFieldEditor());
        	parameterTable_1.getColumnModel().getColumn(1)
    		.setCellRenderer(new MyTextFieldRender());
    	}
    	
        final MouseInputListener mouseInputListener = getMouseInputListener(parameterTable_1,RequestPanel.this,null);
        parameterTable_1.addMouseListener(mouseInputListener);
    }
