我无法找出我做错了什么。我必然会在Form Bean中使用Form Bean,因为表单中有许多不同的部分。基本上,在同一表格上有一个响应部分和请求部分。
在初始化视图时,我得到一个没有getter方法的异常。我正在使用Struts 1.2
javax.servlet.jsp.JspException: No getter method for property getAvailableAddres
sRequest.resellerId of bean org.apache.struts.taglib.html.BEAN
at org.apache.struts.util.RequestUtils.lookup(RequestUtils.java:968)
struts-config.xml中:
<form-beans>
<form-bean name="getAvailableAddress" type="com.wisor.talktalk.model.GetAvailableAddress" />
<form-bean name="provideRequest" type="com.wisor.talktalk.common.talktalkbean.RequestActionForm" />
</form-beans>
<action-mappings>
<action path="/ttTestJsp" type="com.wisor.talktalk.controller.TestJsp"
name="getAvailableAddress"
scope="session"
validate="false"
unknown="false">
<forward name="init" path="/WEB-INF/talk/preorderView/getAvailableAddress.jsp"/>
</action>
</action-mappings>
JSP页面:
<html:form action="/ttTestJsp.do?task=getResponse" styleClass="form">
<fieldset>
<label class="inline label" for="reseller_id"><fmt:message
key="label.field.resellerId" />:</label>
<html:text
property="getAvailableAddressRequest.resellerId"
styleClass="mandatory" readonly="readonly"></html:text>
</fieldset>
<html:submit value="GetAddress"/>
</html:form>
FormBean Main:
public class GetAvailableAddress extends ActionForm{
private GetAvailableAddressRequest getAvailableAddressRequest;
public void intilize(){
getAvailableAddressRequest = new GetAvailableAddressRequest();
}
public GetAvailableAddressRequest getGetAvailableAddressRequest(){
return this.getAvailableAddressRequest;
}
public void setGetAvailableAddressRequest(GetAvailableAddressRequest getAvailableAddressRequest){
this.getAvailableAddressRequest = getAvailableAddressRequest;
}
}
子形态Bean:
public class GetAvailableAddressRequest implements Serializable{
private String resellerId;
public String getResellerID(){
return this.resellerId;
}
public void setResellerID(String resellerId){
this.resellerId = resellerId;
}
}
行动类:
public class TestJsp extends Action {
Logger logger = Logger.getLogger(this.getClass());
@Override
public ActionForward execute( ActionMapping map, ActionForm actionForm,
HttpServletRequest request, HttpServletResponse response) throws Exception{
ActionForward forward = null;
GetAvailableAddress form = (GetAvailableAddress) actionForm;
form.intilize();
forward = map.findForward("init");
return forward;
}}
看来你的ressellerId字段的getter和setter在GetAvailableAddressRequest类中没有正确命名。您正在使用方法名称末尾的ID而不是下面的Id Corrected签名:
public String getResellerId(){
return this.resellerId;
}
public void setResellerId(String resellerId){
this.resellerId = resellerId;
}
请记住,输入标记的属性名称必须与操作表单中的getter方法名称匹配
示例:在jsp中
<html:textarea property="productDescription" rows="15" cols="50" >
</html:textarea>
在行动表格中
public String getProductDescription() {
return productDescription;
}
对于重定向到此处的其他人:首先检查所有变量/方法名称。
对我来说问题是Form Bean请求POJO类(带有getter和setter的类)的值以显示初始的jsp;因为它们没有价值,所以它们返回了一个空值,让jsp认为没有吸气剂。
只需设置默认值,即使是“”。
public class GetAvailableAddressRequest implements Serializable{
//private String resellerId;
private String resellerId = "defaultValue";
public String getResellerID(){
return this.resellerId;
}
public void setResellerID(String resellerId){
this.resellerId = resellerId;
}
这为我修好了!
