Question

springmvc 获取到header怎么返回

Answer 1

建议使用这种方法，这样可避免每个方法都加入HttpHeaders参数

Java代码

@Controller
@RequestMapping("/hello")
public class HelloController {
@Autowired
private HttpServletRequest request;

@RequestMapping(value="/printname/{name}", method=RequestMethod.GET)
public String printName(@PathVariable String name,
@RequestHeader HttpHeaders headers) {
System.out.println("from request:" + request.getHeader("code"));
System.out.println("from parameter:" + headers.getFirst("code"));

return "hello";
}
}
