自己找到了解決方案：更改了 getAllFiles 方法，如下所示：InetAddress ip = null;@RequestMapping("/getAllFiles") public ResponseEntity<List<String>> getAllFiles(@RequestParam String panelName) { try { ip = InetAddress.getLocalHost(); } catch (UnknownHostException e) { // TODO Auto-generated catch block e.printStackTrace(); } List<String> fileNamesList = panelFileListMap.get(panelName); if (fileNamesList != null) { List<String> allFiles = fileNamesList.stream() .map(fileName -> MvcUriComponentsBuilder .fromMethodName(ContentResource.class, "getFile", fileName, panelName) .host(ip.getHostAddress()).build().toString()) .collect(Collectors.toList()); return ResponseEntity.ok().body(allFiles); } else { throw new RuntimeException("No images are uploaded in category = " + panelName); } }

在 if 條件中使用 break 語句并將布爾值設(shè)置為變量。在 for 循環(huán)結(jié)束后檢查該布爾變量的狀態(tài)。如果為真，則使用 break 語句跳出 while 循環(huán)。
while (!(list.contains("NORTH SOUTH") || list.contains("SOUTH NORTH") || list.contains("WEST EAST") || list.contains("EAST WEST"))) {
boolean conditionChecker=false;
for (int i = 0; i < list.size(); i++) {
for (int k = i + 1; k < list.size(); k++) {
if (list.get(i).contains("NORTH") && list.get(k).contains("SOUTH") ||
list.get(i).contains("SOUTH") && list.get(k).contains("NORTH") ||
list.get(i).contains("WEST") && list.get(k).contains("EAST") ||
list.get(i).contains("EAST") && list.get(k).contains("WEST")) {
list.remove(i);
list.remove(k - 1);
conditionChecker=true;
break;
}
}
if(conditionChecker==true){
break;
}
}
