<form action="add.action" method="post" name="form1">
<input type="text" name="book.name"/>
<input type="text" name="book.author"/>
<input type="text" name="book.price"/>
<input type="submit">

应该用struts2的表单<s:form></s:form>，然后在action写set和get方法，普通的表单不行！

<form action="add.action" method="post" name="form1">
<input type="text" name="book.name"/>
<input type="text" name="book.author"/>
<input type="text" name="book.price"/>
<input type="submit">
</form>
只是struts2的表单？
<s:form></s:form>.....
