问题描述

我在GAE上执行spring mvc + primeFaces时遇到了问题，我认为除了当我尝试通过发送post来修改我的bean的值时，所有工作都正常，值与以前保持一致。这里是代码：

web.xml

} 
 
 
}

}

} 
 public void setParam2（String param2）{
 this.param2 = param2; 
} 
 public String getParam3（）{
 return param3; 
} 
 public void setParam3（String param3）{
 this.param3 = param3; 
} 
 
 
 
}

index.xhtml 

 < html> 
 
< ui：composition template =baseLayout.xhtml> 
< ui：define name =content> 
 
< form action =homemethod =post> 
< h：panelGrid style =margin-top：20px; columns =2cellpadding =10> 
 
< p：outputPanel autoUpdate =true> 
 
< p：inputText value =＃{task.param1}/> 
< p：inputText value =＃{task.param2}/> 
 
 
< p：inputTextarea value =＃{task.param3}id =textrows =10cols =50/> 
 
< / p：outputPanel> 
 
 
 
 
< / h：panelGrid> 
< button value =submit/> 
 
< / form> 
 
 
< / ui：define> 
< / ui：composition> 
 
 
< / html>


解决方案

只需转动 

 < form action =homemethod =post> 
< h：panelGrid style =margin-top：20px; columns =2cellpadding =10> 
< p：outputPanel autoUpdate =true> 
 
< p：inputText value =＃{task.param1}/> 
< p：inputText value =＃{task.param2}/> 
 
< p：inputTextarea value =＃{task.param3}id =textrows =10cols =50/> 
 
< / p：outputPanel> 
< / h：panelGrid> 
< button value =submit/> 
 
< / form>

成

 < H：形式> 
< h：panelGrid style =margin-top：20px; columns =2cellpadding =10> 
< p：outputPanel autoUpdate =true> 
 
< p：inputText value =＃{task.param1}/> 
< p：inputText value =＃{task.param2}/> 
 
< p：inputTextarea value =＃{task.param3}id =textrows =10cols =50/> 
 
< / p：outputPanel> 
< / h：panelGrid> 
< p：commandButton value =submitaction =＃{task.myMethod}/> 
 
< / h：表格>

使用以下方法 

  public void myMethod（）{
 System.out.println（param1）; 
 System.out.println（param2）; 
 System.out.println（param3）; 
}


I have a problem with implementing spring mvc + primeFaces on GAE, i think that all works fine except when i try to modify values of my bean by sending post, values remain the same as before. Here is code:

web.xml

    <context-param>
        <param-name>javax.faces.PROJECT_STAGE</param-name>

    </context-param>

     <context-param>

<ui:composition template="baseLayout.xhtml">

                <form action="home" method="post">
                <h:panelGrid style="margin-top:20px;" columns="2" cellpadding="10">

                    <p:outputPanel autoUpdate="true">

            </form>

</ui:composition>


</html>

解决方案

Just turn

<form action="home" method="post">
    <h:panelGrid style="margin-top:20px;" columns="2" cellpadding="10">
        <p:outputPanel autoUpdate="true">

            <p:inputText value="#{task.param1}" />
            <p:inputText value="#{task.param2}" />

            <p:inputTextarea value="#{task.param3}" id="text" rows="10" cols="50" />

        </p:outputPanel>
    </h:panelGrid>
    <button value="submit" />

</form>

Into

<h:form>
    <h:panelGrid style="margin-top:20px;" columns="2" cellpadding="10">
        <p:outputPanel autoUpdate="true">

            <p:inputText value="#{task.param1}" />
            <p:inputText value="#{task.param2}" />

            <p:inputTextarea value="#{task.param3}" id="text" rows="10" cols="50" />

        </p:outputPanel>
    </h:panelGrid>
    <p:commandButton value="submit" action="#{task.myMethod}"/>

</h:form>

with the following method

public void myMethod(){
    System.out.println(param1);
    System.out.println(param2);
    System.out.println(param3);
}
