How can I map a form to two different methods in controller using RequestMapping?

Question

So my Spring MVC project home page has two input fields within a form.

The user can enter the roll number or name.

Jsp

<form action="search" method="GET" >
        <div style="text-align: center;">
            <input  type="text" id="regNo" name="regNo" size="30" maxLength="50" "></input> or 
            <input  id="studentName" type="text" size="30" maxLength="50" "></input>
</form>

In my controller, I have two methods mapped to two input fields.

@RequestMapping(value ="/search", method = RequestMethod.GET)
    public String getStudent(String regNo, ModelMap model){

        return "A";
    }

    @RequestMapping(value="/search", method = RequestMethod.GET)
    public String searchStudentByName(String studentName, ModelMap model){

        return "B";
    }

Since both the input fields are String, I don't know how can I map them to two different methods in controller?

Answer 1

Did you want something like this :

@RequestMapping(method= RequestMethod.GET,value = "/search/r/regNo={regNo}")
public String getStudent(@PathVariable String regNo){

}

for studentName :

@RequestMapping(method= RequestMethod.GET,value = "/search/s/studentName={studentName}")
public String getStudent(@PathVariable String studentName){

}

then you need to add both request in different form tag, & in action tag provide :

if regNo send :

/search/r/

for studentName :

/search/s/

Jsp :

<form action="search/r" method="GET" >
        <div style="text-align: center;">
            <input  type="text" id="regNo" name="regNo" size="30" maxLength="50" "></input> 
            <input type="submit" name="approve" value="RegNo" />
</form>    
<form action="search/s" method="GET" >
        <div style="text-align: center;">
            <input  id="studentName" type="text" size="30" maxLength="50" "></input>
            <input type="submit" name="approve" value="StudentName" />
</form>

OR Second way to do so :

<form action="search" method="GET" >
                <input  type="text" id="regNo" name="regNo" size="30" maxLength="50" "></input> 
                <input  id="studentName" type="text" size="30" maxLength="50" "></input>

                <input type="submit" name="regno" value="regno" />
                <input type="submit" name="studentName" value="studentName" />
</form>

controller :

@RequestMapping(value = "/search", method = RequestMethod.GET, params = { "regno" })
public String getRegno(@RequestParam String regno) {

}

@RequestMapping(value = "/search", method = RequestMethod.GET, params = { "studentName" })
public String getStudent(@RequestParam String studentName) {

}
