摘要：
插入单个请求标头@GetMapping（“/bbb”）publicResponseEntity<；System.out。打印（m1）；returnResponseEntity.status（302）.headers（headers）。正文（m1）；@GetMapping（“/bbb”）publicResponseEntity<；
ResponseEntity处理响应信息

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));
}
