1.@Controller
2.@RequestMapping
3.@RequestParam
public String getUser(HttpSession session,
@RequestParam(value="pageNUmber",required = false,defaultValue="1")int pageNUmber,
@RequestParam(value="pageLength",required = false,defaultValue="10")int pageLength){
4.@PathVariable
@RequestMapping("/user/selectUser/{id}")
@ResponseBody
public String getUserById(HttpSession session,@PathVariable int id){
User user=userServcie.findUserById(id);
return user;
}
postman测试
5.@RequestHeader
封装请求头信息
//请求头信息封装
public class Header {
private String Connection;
private String Cookie;
private String Host;
public String getConnection() {
return Connection;
}
public void setConnection(String connection) {
Connection = connection;
}
public String getCookie() {
return Cookie;
}
public void setCookie(String cookie) {
Cookie = cookie;
}
public String getHost() {
return Host;
}
public void setHost(String host) {
Host = host;
}
}
写控制器
//获得请求头
@RequestMapping("/setting/getMessage")
@ResponseBody
public Header getMessage(@RequestHeader("Connection") String Connection,
@RequestHeader("Cookie") String Cookie,@RequestHeader("Host") String Host) {
Header header=new Header();
header.setConnection(Connection);
header.setCookie(JSESSIONID);
header.setHost(Host);
return header;
}
postman测试
6.@CookieValue
写控制器
@CookieValue ("JSESSIONID") String JSESSIONID,
可将JSESSIONID绑定到方法体中
7.@SessionAttributes
注:只能用在类上
@Controller
@SessionAttributes("user") public class UserController {
将Model中的属性名为user的属性放入HttpSession中
8.@ModelAttribute]o
