实例讲解Java批量插入、更新数据

Java的批量添加数据，多个字段同时添加多条数据，我不知道你遇到过没有。今天我们就以一个具体的实例来说一下Java的批量添加数据，面向的是Oracle数据库。

            personFamilyInfoService.merge(personFamilyInfolist.get(i));
          }
        }catch (Exception e) {
          e.printStackTrace();
        }  

      }
    }</span>  

这样，java多字段、多条数据批量添加的例子就完成了，主要要注意前台页面叠加出现多行的js函数和后台的添加和更新方法，用list接收，循环遍历进行添加。除此之外这里我想说一下下面这段代码：

代码如下:

<span style="font-family:KaiTi_GB2312;font-size:14px;">$(function(){ 
    loadCheck(); 
});</span>

它就是如下代码的缩写：

代码如下:

<span style="font-family:KaiTi_GB2312;font-size:14px;"> $(document).ready(function(){ 
        loadCheck(); 
});</span>

其实这个代码和下面的代码是一个意思：

代码如下:

<span style="font-family:KaiTi_GB2312;font-size:14px;">window.onload=function(){ 
       loadCheck(); 
}</span>

这样就不用在body的onload事件里面调用，只需要在js程序段里面编写就可以了。虽然下面的代码可以和上面两个互换，但他们之间又有不同。首先是执行时间不同，$(document).ready在页面框架下载完毕后就执行，而window.onload必须在页面全部加载完毕（包含图片下载）后才能执行。很明显前者的执行效率高于后者。再就是执行数量的不同，$(document).ready可以重复写多个，而且每次执行结果不同；而window.onload尽管可以执行多个，但仅输出最后一个执行结果，无法完成多个结果的输出。

以上就是本文的全部内容，希望对大家的学习有所帮助。
