SSM項目遇到的問題（二）

1.找不到mapper

Caused by: java.lang.IllegalArgumentException: Could not resolve resource location pattern [cn/wh3t/mapper/*.xml]: ServletContext resource [/cn/wh3t/mapper/] cannot be resolved to URL because it does not exist at org.springframework.core.io.support.ResourceArrayPropertyEditor.setAsText(ResourceArrayPropertyEditor.java:120) at org.springframework.beans.TypeConverterDelegate.doConvertTextValue(TypeConverterDelegate.java:429) at org.springframework.beans.TypeConverterDelegate.doConvertValue(TypeConverterDelegate.java:402) at org.springframework.beans.TypeConverterDelegate.convertIfNecessary(TypeConverterDelegate.java:155) at org.springframework.beans.AbstractNestablePropertyAccessor.convertIfNecessary(AbstractNestablePropertyAccessor.java:585) ... 77 more

解決：value中加入classpath，在接後面的路徑

2.關於pojo、dto、vo和JavaBeans的區別

Difference between DTO, VO, POJO, JavaBeans?

What is the difference between a JavaBean and a POJO?

What is the difference between POJO (Plain Old Java Object) and DTO (Data Transfer Object)?

3.html頁面中，iframe引入的頁面會變得特別小

頁面一切正常，height="100%"，以後強行height="500px"調整了引入頁面的高度，可是，看起來並很差，內容過多時，一樣也會顯示不全。

解決： iframe 根據內容自適應高度-終極解決方案

function iframeLoad()
{
    document.getElementById("iframe").height=0;
    document.getElementById("iframe").height=document.getElementById("iframe").contentWindow.document.body.scrollHeight;
}
