方法一:

塞单个请求头

    @GetMapping("/bbb")
    public ResponseEntity<Map> delete_User2 (HttpServletRequest HttpServletRequest) {
        HttpHeaders headers = new HttpHeaders();
        headers.add("Custom-Header", "foo");
        Map m1 = new HashMap();
        m1.put("name", "张三");

        return ResponseEntity.status(302).header("location", "http://202.108.22.5/").body(m1);

    }

塞多个请求头 (这个最好)

    @GetMapping("/bbb")
    public ResponseEntity<Map> delete_User2 (HttpServletRequest HttpServletRequest) {
        HttpHeaders headers = new HttpHeaders();
        headers.add("Custom-Header", "foo");
        headers.add("Custom-Header222", "foo222");
        Map m1 = new HashMap();
        m1.put("name", "张三");
        System.out.print(m1);
        log.info(HttpServletRequest.getHeader("lucax"));
        return ResponseEntity.status(302).headers(headers).body(m1);
    }

　　

方法二:

    @GetMapping("/bbb")
    public ResponseEntity<Map> delete_User2 (HttpServletRequest HttpServletRequest) {
        HttpHeaders headers = new HttpHeaders();
        headers.add("Custom-Header", "foo");
        headers.add("Custom-Header222", "foo222");
        log.info(HttpServletRequest.getHeader("lucax"));
        return new ResponseEntity("Custom header set", headers, HttpStatus.resolve(300));
    }
