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 morehtml

解决：value中加入classpath，在接后面的路径java

2.关于pojo、dto、vo和JavaBeans的区别

Difference between DTO, VO, POJO, JavaBeans?spring

What is the difference between a JavaBean and a POJO?bash

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

3.html页面中，iframe引入的页面会变得特别小

页面一切正常，height="100%"，以后强行height="500px"调整了引入页面的高度，可是，看起来并很差，内容过多时，一样也会显示不全。spa

解决： iframe 根据内容自适应高度-终极解决方案.net

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