解決方式：減小布局嵌套層數，特別是用到相似tabHost,ViewPager的控件時，要考慮到最底層的 activity 的

contentView的佈局，儘可能簡化，多用RelativeLayout替代LinearLayout

一樣再優化列表滑動效率的時候，簡化item佈局也能帶來巨大的體驗提高

二，函數調用層級太多致使的 java.lang.StackOverflowError，如死循環，遞歸等

StackOverflowError是因爲當前線程的棧滿了  ，也就是函數調用層級過多致使。

好比死遞歸。

如：

  public String homePage(){
  this.findAllNews();
   return "shouye";
 }

 

public String findAllNews(){
   List newslist= hotnewsService.findAll();
   HotnewsDto  hotnews= (HotnewsDto) newslist.get(0);//獲得第一條新聞
   String content=hotnews.getContent();
   String subcontent=content.substring(0, 80);//截取這條新聞信息內容在首頁部分顯示
   super.setRequestAttribute("hotnews", hotnews);
   super.setRequestAttribute("newslist", newslist);
   super.setRequestAttribute("subcontent", subcontent);
   return homePage;

   }

  如紅色標記處，這樣子調用的方法，至關於一個無限循環了！

解決辦法：

  我習慣將 findAllNews方法的返回值設爲 void 便可
