杂乱代码区

iq  对select 选中的option信息抓取

<option value="0" <c:if test="${vo.gd_state == 0}">selected="selected"</c:if>>待确认。</option>
<option value="1" <c:if test="${vo.gd_state == 1}">selected="selected"</c:if>>确认通过，待检测。</option>
<option value="4" <c:if test="${vo.gd_state == 4}">selected="selected"</c:if>>审核不通过。</option>

jstl 里面判断字符串长度并截取(jsp中)

${fn:length(o.content)>'5'?o.content.substring(0,5):o.content}

或下面这种，用fn:substring(vo.name, 0, 5)来截取字符串，效果一样

${(fn:length(vo.name) gt 6) ? (fn:substring(vo.name, 0, 5)).concat("..."): vo.name} 

java调用shell脚本文件

Process process = Runtime.getRuntime().exec(shellPath.get(0));

exec()参数是.sh文件的绝对路径
