本文记录了一次使用Struts框架时出现的IllegalArgumentException异常过程，详细分析了错误原因在于表单Bean名称与配置文件中定义的名称不一致导致的问题。通过对比代码与配置文件，找出并修正了命名差异。

代码没有报错，但是总是报错，运行的时候出发一个按钮以后总是报错，仔细查看下是

public ActionForward expReport(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)
		throws Exception {


		LazyValidatorForm lazyForm = ( LazyValidatorForm ) form;
		HB010051_BoangDto hb010051_BoangDto = ( HB010051_BoangDto ) lazyForm.get("HB010051_BoangFormBean");  中的引用的名称和struts.xml中的<form-beans>

		<!-- 运营报表 增加字段-->
		<form-bean name="HB010051_BoangForm"
			type="org.apache.struts.validator.LazyValidatorForm">
			<form-property name="HB010051_BoangFormBean"
				type="com.neusoft.hotel.app.HB018.dto.HB010051_BoangDto" />
		</form-bean>

名称不一样！
