Spring @RequestMapping Annotation

=> Based on this Annotation only Request will come to any method in the Controller.

=> We can mention that , the method is supporting either POST request or GET request

=> We can mention the value of the url 
(Ex : http://ip:port/projName/..../value)
For each method we have to differentiate the value

=> We can append variables with URL as Path Variables

=> We can append variables with URL as Request Parameters

Annotation 

@RequestMapping

import org.springframework.web.bind.annotation.RequestMapping;

How to specify the method is only supports either POST / GET ?

@RequestMapping(value="/callController1", method=RequestMethod.GET)

@RequestMapping(value="/callController1", method=RequestMethod.POST)

@RequestMapping(value="/callController1", method={RequestMethod.GET,RequestMethod.POST})
[It will support both GET and POST Requests]


@PathVariable Example

@RequestMapping(value="/callController2/{name}",method=RequestMethod.GET)

public ModelAndView method2(@PathVariable("name") String person) {
           // Write the Code whatever you want
}

Ex URL : http://localhost:8888/SpringMVC/spring/callController2/Ram

For More Path variables 

@RequestMapping(value="/callController2/{name}/one/{salary}",method=RequestMethod.GET)

Ex URL : http://localhost:8888/SpringMVC/spring/callController2/Ram/one/50000

@RequestParam with Params attribute

@RequestMapping(value="/callController3",params="id",method=RequestMethod.GET)
public ModelAndView method3(@RequestParam("id") String uid) {
// Code

}

Ex URL : http://localhost:8888/SpringMVC/spring/callController3?id=25

For Multiple Request Parameters

@RequestMapping(value="/callController5",params={"id","name"},method={RequestMethod.GET,RequestMethod.POST})
public ModelAndView method5(@RequestParam("id") String uid,@RequestParam("name") String name) {
// Code

}

Ex URL : http://localhost:8888/SpringMVC/spring/callController5?id=25&name=Ram


Example :

package com.ram;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class SpringMvcController {

//http://localhost:8888/SpringMVC/spring/springController
//By default it will support GET method
@RequestMapping(value="/springController")
public String method() {

return "returnPage";

}

//http://localhost:8888/SpringMVC/spring/callController1
@RequestMapping(value="/callController1",method=RequestMethod.GET)
public String method1(ModelMap model) {

model.addAttribute("key1", "Hi Ram");

return "returnPage1";

}

//http://localhost:8888/SpringMVC/spring/callController2/Ram
@RequestMapping(value="/callController2/{name}",method=RequestMethod.GET)
public ModelAndView method2(@PathVariable("name") String person) {

ModelAndView model = new ModelAndView();
model.setViewName("returnPage2");
model.addObject("msg1", person);
model.addObject("msg2", "This is Message2");

return model;

}

//http://localhost:8888/SpringMVC/spring/callController3?id=25
//It will suppoert Both POST and GET
@RequestMapping(value="/callController3",params="id",method={RequestMethod.GET,RequestMethod.POST})
public ModelAndView method3(@RequestParam("id") String uid) {

ModelAndView model = new ModelAndView();
model.setViewName("returnPage3");
model.addObject("msg1", uid);

return model;

}



//http://localhost:8888/SpringMVC/spring/callController4
@RequestMapping(value="/callController4",method=RequestMethod.GET)
public ModelAndView method4() {

ModelAndView model = new ModelAndView("returnPage4");
model.addObject("msg5", "Hi Ram");

return model;

}

//http://localhost:8888/SpringMVC/spring/callController5?id=25&name=Ram
//It will suppoert Both POST and GET
@RequestMapping(value="/callController5",params={"id","name"},method={RequestMethod.GET,RequestMethod.POST})
public ModelAndView method5(@RequestParam("id") String uid,@RequestParam("name") String name) {

ModelAndView model = new ModelAndView();
model.setViewName("returnPage5");
model.addObject("id", uid);
model.addObject("name", name);

return model;

}

}
