下面的代码中，因为我是使用
for (Iterator<Element> i = el.elements().iterator(); i.hasNext(); )
迭代器遍历根节点的所有子节点的flag，但是因为linux基线有 <initcmd> 节点，导致flag为空，
在传入service中进行数据库操作时抛出异常未被处理导致程序被挂起，错误信息不输出到console，直接打印到了页面。
解决方法就是try catch处理掉异常并返回false即可
public boolean isFound(String xcwIndex) {
try {
XconfigLinuxExample example = new XconfigLinuxExample();
XconfigLinuxExample.Criteria criteria = example.createCriteria();
criteria.andXcwindexEqualTo(xcwIndex);
long count = xconfigLinuxMapper.countByExample(example);
return count > 0;
}catch (Exception e){
// System.out.println("xcwIndex为空，当次未遍历到flag");
return false;
}
}
