Spring Framework 6 MVC 若要啟用 @GetMapping @PostMapping 要再設定檔中，增加設定如下:
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
<mvc:annotation-driven />
完整內容如下:
<?xml version="1.0" encoding="UTF-8"?>

Spring Framework 6 MVC 在 Controller 中使用 @GetMapping @PostMapping
@GetMapping 等同 @RequestMapping (method = RequestMethod.GET)
@PostMapping 等同 @RequestMapping (method = RequestMethod.POST)
Spring Framework 6 MVC 在 Controller 中使用 @RequestParam
@RequestMapping("/login")
public String login(
@RequestParam(value="id", required=true) String id,
@RequestParam(value="paswd", required=false) String paswd){
.......
}
Spring Framework 6 MVC 在 Controller 中使用 @PathVariable
@RequestMapping("/student/{id}")
public String getDetails(@PathVariable(value="id") String id){
.......
}
Spring Framework 6 MVC 在 Controller 中使用 @ModelAttribute
@RequestMapping(value = "/addEmployee", method = RequestMethod.POST)
public String submit(@ModelAttribute("employee") Employee employee) {
return "employeeView";
}
Spring Framework 6 MVC 在 Controller 中使用 @SessionAttributes
package com.tcg.action;
@Controller
@SessionAttributes("carmemberid")
public class LoginAction {
@RequestMapping("login")
public String hello(@RequestParam(value = "carmemberid" ) String carmemberid ,
@RequestParam(value = "paswd", required = false ) String paswd
, Model m) {
String nextPage ="login";
if(paswd!= null){
m.addAttribute("paswd", paswd);//使用範圍 request
m.addAttribute("carmemberid", carmemberid); //使用範圍 session
}else{//使用者不存在
nextPage ="reLogin";
}
return nextPage;
}
}
