Spring Framework，启用PUT方法

@RequestMapping(method= RequestMethod.GET)  
public String getCity(@PathVariable(value="cid") String cid, @RequestParam(value="State") Integer state,  Model model) {
    System.out.println("get request");  
    return "index";  
}


@RequestMapping(method= RequestMethod.PUT)  
public String putCity(@PathVariable(value="cid") String cid, @RequestParam(value="State") Integer state, Model model) {
    System.out.println("put request");
    return "index";
}

@Controller
@RequestMapping(value="/retail/{cid}/master/city")
public class City {

    @RequestMapping(value="/foo1", method= RequestMethod.GET)  
    public String getCity(@PathVariable(value="cid") String cid, @RequestParam(value="State")   Integer state,  Model model) {
        System.out.println("get request");  
        return "index";  
    }

    @RequestMapping(value="/foo2", method= RequestMethod.PUT)  
    public String putCity(@PathVariable(value="cid") String cid, @RequestParam(value="State") Integer state, Model model) {
        System.out.println("put request");
        return "index";
    }
}
