标签：标记 get请求 消息 通过 mil param efault 指定 msu
首先来看下一段代码：
@Controller
@RequestMapping("/user")
public class UsersController {
@RequestMapping(value="/findAll")
private String findAll(){
return "index";
}
}
@Controller：表明这个类是一个控制器类。假设用这个注解。须要在spring-mvc配置文件加上这一段。<context:component-scan base-package="com.ztz.springmvc.controller"/>
@RequestMapping：能够为控制器指定处理能够请求哪些URL请求，@RequestMapping能够定义在类或方法上。
相对于类定义处的 URL。
若类定义处未标注 @RequestMapping。则方法处标记的 URL 相对于WEB 应用的根文件夹
@Controller
@RequestMapping("/user")
public class UsersController {
@RequestMapping(value="/findAll",method=RequestMethod.GET)
private String findAll(){
System.out.println("仅仅接受get请求");
return "index";
}
}@Controller
@RequestMapping("/user")
public class UsersController {
@RequestMapping(value="/findAll",method=RequestMethod.POST)
private String findAll(){
System.out.println("仅仅接受post请求");
return "index";
}
}@Controller
@RequestMapping("/user")
public class UsersController {
@RequestMapping(value="/findAll",params="name")
private String findAll(){
System.out.println("仅仅接受name參数");
return "index";
}
}
@Controller
@RequestMapping("/user")
public class UsersController {
@RequestMapping(value="/findAll",headers="Content-Type:text/html;charset=UTF-8")
private String findAll(){
System.out.println("仅仅接受请求头中Content-Type为text/html;charset=UTF-8的请求");
return "index";
}
}
@Controller
@RequestMapping("/user")
public class UsersController {
@RequestMapping(value="/findAll")
private String findAll(@RequestParam(value="name",required=true)String name,//參数name不能为空
@RequestParam(value="sex",required=false)String sex,//參数sex能够为空
@RequestParam(value="age",defaultValue="20")String age){//參数age假设为空，默认值为20
System.out.println(name);
System.out.println(sex);
System.out.println(age);
return "index";
}
}@Controller
@RequestMapping("/user")
public class UsersController {
@RequestMapping(value="/findAll")
private String findAll(@RequestHeader(value="User-Agent")String user_Agent,
@RequestHeader(value="Cookie")String cookie){
System.out.println(user_Agent);
System.out.println(cookie);
return "index";
}
}@Controller
@RequestMapping("/user")
public class UsersController {
@RequestMapping(value="/findAll")
private String findAll(@CookieValue(value="JSESSIONID")String cookie){
System.out.println(cookie);
return "index";
}
}
@Controller
@RequestMapping("/user")
public class UsersController {
@RequestMapping(value="/findAll",method=RequestMethod.POST)
private String findAll(@RequestBody(required=true) String body){
System.out.println(body);
return "index";
}
}
springmvc之@Controller、@RequestMapping等注解解说
