问题一:<html:link action="/http2?method=delete&college='<bean:write name="element"/>'">delete</html:link>要用<bean:write name="element"/>作为参数,但按上面这样写时页面提示错误,请问有没有能正确的途径让college的值为bean的属性值,
struts-config.xml配置文件如下
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
<struts-config>
<data-sources />
<form-beans >
<form-bean name="http2Form" type="com.yourcompany.struts.form.Http2Form" />
</form-beans>
<global-exceptions />
<global-forwards >
<forward name="add" path="/form/add.jsp" />
<forward name="delete" path="/form/delete.jsp" />
<forward name="modify" path="/form/modify.jsp" />
</global-forwards>
<action-mappings >
<action
attribute="http2Form"
input="/form/http2.jsp"
name="http2Form"
path="/http2"
parameter="method"
scope="request"
type="com.yourcompany.struts.action.Http2Action" />
</action-mappings>
<message-resources parameter="com.yourcompany.struts.ApplicationResources" />
</struts-config>
问题二:将上面的<html:link 改写为<a href="/http2?method=delete&college=<bean write name="element"/>">delete</a>
提交后不执行DispatchAction的delete方法,而连接到其他页面了,
请问是什么原因啊？
