how to get param in method post spring mvc?

I'm using spring mvc. And I can't get param from url when method = post. But when I change method to GET, so I can get all param.

This is my form:

<form method="POST" action="http://localhost:8080/cms/customer/create_customer" id="frmRegister" name ="frmRegister" enctype="multipart/form-data">
<input class ="iptRegister" type="text" id="txtEmail" name="txtEmail" value="" />
<input class ="iptRegister" type="password" id="txtPassword" name="txtPassword" value="" />
<input class ="iptRegister" type="text" id="txtPhone" name="txtPhone" value="" />

<input type="button" id="btnRegister" name="btnRegister" value="Register" onclick="" style="cursor:pointer"/>
</form>

This is my controller:

@RequestMapping(value= "/create_customer", method = RequestMethod.POST)
@ResponseBody
public String createCustomer(HttpServletRequest request,
@RequestParam(value="txtEmail", required=false) String email,
@RequestParam(value="txtPassword", required=false) String password,
@RequestParam(value="txtPhone", required=false) String phone){

ResultDTO<String> rs = new ResultDTO<String>();
rs.setStatus(IConfig.SHOW_RESULT_SUCCESS_ON_MAIN_SCREEN);
try{
Customer c = new Customer();
c.setEmail(email);
c.setPassword(password);
c.setPhone(phone);
customerService.insert©;
rs.setData("Insert success");
}catch(Exception ex){
log.error(ex);
rs.setStatus(IConfig.SHOW_RESULT_ERROR_ON_MAIN_SCREEN);
rs.setData("Insert failure");
}
return rs.toString();
}

How can I resolved this?

1. Spring annotations will work fine if you remove `enctype="multipart/form-data"`.

@RequestParam(value="txtEmail", required=false)

2. You can even get the parameters from the `request` object .

request.getParameter(paramName);

3. Use a [form](

) in case the number of attributes are large. It will be convenient. [Tutorial](

) to get you started.

4. Configure the Multi-part resolver if you want to receive `enctype="multipart/form-data"`.

<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="maxUploadSize" value="250000"/>
</bean>

Refer the [Spring documentation](

).

It also works if you change the content type

<form method="POST"
action="http://localhost:8080/cms/customer/create_customer"
id="frmRegister" name="frmRegister"
enctype="application/x-www-form-urlencoded">

In the controller also add the header value as follows:

@RequestMapping(value = "/create_customer", method = RequestMethod.POST, headers = "Content-Type=application/x-www-form-urlencoded")

You should use `@RequestParam` on those resources with method `= RequestMethod.GET`

In order to post parameters, you must send them as the request body. A body like JSON or another data representation would depending on your implementation (I mean, consume and produce `MediaType`).

Typically, <i> multipart/form-data </i> is used to upload files.

When I want to get all the **POST** params I am using the code below,

@RequestMapping(value = "/", method = RequestMethod.POST)
public ViewForResponseClass update(@RequestBody AClass anObject) {
// Source..
}

I am using the **`@RequestBody`** annotation for post/put/delete http requests instead of the `@RequestParam` which reads the GET parameters.
