微信菜单json拼接方法：

private String getWxButtonJson(List<WxButton> wxButtonsParent){
StringBuffer sb = new StringBuffer("{");
sb.append("\"").append("button").append("\"").append(":").append("[");
for (WxButton wxButton : wxButtonsParent) {
sb.append("{");
sb.append("\"").append("name").append("\"").append(":").append("\"").append(wxButton.getName()).append("\"").append(",");
if(wxButton.getSub_buttons().size() > 0){
sb.append("\"").append("sub_button").append("\"").append(":").append("[");
StringBuffer subStringBuffer = new StringBuffer("");
for (WxButton sub : wxButton.getSub_buttons()) {
subStringBuffer.append("{");
subStringBuffer.append("\"").append("name").append("\"").append(":").append("\"").append(sub.getName()).append("\"").append(",");
subStringBuffer.append("\"").append("type").append("\"").append(":").append("\"").append(sub.getType().toLowerCase()).append("\"").append(",");
if(ButtonType.CLICK.toString().equalsIgnoreCase(sub.getType())){
subStringBuffer.append("\"").append("key").append("\"").append(":").append("\"").append(sub.getKey()).append("\"").append(",");
}else{
subStringBuffer.append("\"").append("url").append("\"").append(":").append("\"").append(sub.getUrl()).append("\"").append(",");
}
if(subStringBuffer.indexOf(",") > -1){
subStringBuffer.deleteCharAt(subStringBuffer.lastIndexOf(","));
}
subStringBuffer.append("}").append(",");
}
if(subStringBuffer.indexOf(",") > -1){
subStringBuffer.deleteCharAt(subStringBuffer.lastIndexOf(","));
}
sb.append(subStringBuffer).append("]");
}else{
sb.append("\"").append("type").append("\"").append(":").append("\"").append(wxButton.getType().toLowerCase()).append("\"").append(",");
if(ButtonType.CLICK.toString().equalsIgnoreCase(wxButton.getType())){
sb.append("\"").append("key").append("\"").append(":").append("\"").append(wxButton.getKey()).append("\"").append(",");
}else{
sb.append("\"").append("url").append("\"").append(":").append("\"").append(wxButton.getUrl()).append("\"").append(",");
}
if(sb.indexOf(",") > -1){
sb.deleteCharAt(sb.lastIndexOf(","));
}
}
sb.append("}").append(",");
}
if(sb.indexOf(",") > -1){
sb.deleteCharAt(sb.lastIndexOf(","));
}
sb.append("]}");
return sb.toString();
}
