Java Spring MVC POST提交不起作用

我的应用服务器是WebLogic12c，它在apache代理的后面工作

当我通过SpringMVC表单执行GetSubmit时，值会到达后端，但当我执行PostSubmit时，所有值在后端都为null

这是我的档案

JSP文件

    <form:form method="post" modelAttribute="userForm" action="createUser">

            <form:input path="userInfo.number" readonly="true" maxlength="100"/>
            <form:input path="userInfo.firstName" readonly="true" maxlength="500"/>
            <form:input path="userInfo.lastName" readonly="true" maxlength="500"/>
            <input type="submit" style="font-weight: bold;"                                             value="Send"></td>
</form:form>

从这一行的外观来看，

userForm.getFirstName（）

，属性firstName、lastName和number似乎是userForm对象的属性，在这种情况下，表单应该是

<form:form method="post" modelAttribute="userForm" action="createUser">
            <form:input path="number" readonly="true" maxlength="100"/>
            <form:input path="firstName" readonly="true" maxlength="500"/>
            <form:input path="lastName" readonly="true" maxlength="500"/>
            <input type="submit" style="font-weight: bold;"                                             value="Send"></td>
</form:form>

根据UserForm类的结构可能略有不同，但您应该从中获得解决方案的要点

尝试使用此url/apps/user/createUser或apps/user/createUser。UserForm有另一个名为user userInfo的对象；并且firstName、lastName和编号映射到该对象。

<form:form method="post" modelAttribute="userForm" action="createUser">
            <form:input path="number" readonly="true" maxlength="100"/>
            <form:input path="firstName" readonly="true" maxlength="500"/>
            <form:input path="lastName" readonly="true" maxlength="500"/>
            <input type="submit" style="font-weight: bold;"                                             value="Send"></td>
</form:form>
