map轉java對象

pom依賴：

<dependency>
  <groupId>commons-beanutils</groupId>
  <artifactId>commons-beanutils</artifactId>
  <version>1.9.3</version>
</dependency>

ConverEntity converEntity = new ConverEntity();   //映射的實體類
BeanUtils.populate(converEntity, map); //主要方法，直接調用就可以

此方法可以解析出soap文件並映射成java對象，網上很多帖子解析不出來標准的soap報文，這里也貼上代碼

  public Map<String, Object> map = new HashMap<String, Object>();

    Document doc = DocumentHelper.parseText(soap);//報文轉成doc對象
    Element root = doc.getRootElement();//獲取根元素，准備遞歸解析這個XML樹
    getCode(root);
    return map;
  }

  public void getCode(Element root) {
    if (root.elements() != null) {
      List<Element> list = root.elements();//如果當前跟節點有子節點，找到子節點
      for (Element element : list) {//遍歷每個節點
        if (element.elements().size() > 0) {
          getCode(element);//當前節點不為空的話，遞歸遍歷子節點；
        }
        if (element.elements().size() == 0) {
           //WordUtils.uncapitalize()方法是把首字符串變成小寫，因為我這里需要處理map集合映射成java對象，對於映射的java命名規范，必須規范才能正確映射
          map.put(WordUtils.uncapitalize(element.getName()), element.getTextTrim());
        }//如果為葉子節點，那么直接把名字和值放入map
      }
