Spring MVC POST submits are not working

Question

My app server is Weblogic 12C and it is working behind an apache proxy.

When I was doing GET submit through the spring MVC form, values are coming to back end, but when I was doing a POST submit, all values comes as null at the backend.

Here is my files.

JSP File

    <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>

Controller

@Controller
@RequestMapping(value = "/")
@SessionAttributes("user")
public class TestController {

@RequestMapping(method = RequestMethod.POST, value="createUser")
    public String createUser(@Valid UserForm userForm,BindingResult result,ModelMap modelMap) {
        LOGGER.debug("Handling POST description" + userForm.getFirstName());
}
}

web.xml

<web-app>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml</param-value>

    </listener>

    <listener> 
        <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
    </listener>

    <filter>
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

            <param-value>true</param-value>

    </filter-mapping>

Answer 1

By the looks of this line userForm.getFirstName() , it seems that the properties firstName , lastName and number are the properties of the userForm object, in that case your form should be

<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>

maybe slightly different depending on the structure of your UserForm class, but you should get a gist of a solution from this
