tem.msg.verify.code=验证码为：[code],请勿泄露给其他人。

@PropertySource("classpath:msg.properties")
@Component
public class MSGConstatns {
 @Value("${tem.msg.verify.code}")
 private String sendCodeMsg;

 public String getSendCodeMsg() {
  return sendCodeMsg;
 }
 public void setSendCodeMsg(String sendCodeMsg) {
  this.sendCodeMsg = sendCodeMsg;
 }
}

 public static String getContent(Map<String, String> params,String content) {
  String reg = "\\{\\w*}";//
  Pattern pattern = Pattern.compile(reg);
  Matcher matcher = pattern.matcher(content);
  while (matcher.find()) {
   String group = matcher.group();//
   String key = group.substring(1, group.length() - 1);
   if (!params.containsKey(key))
    throw new NormalException("未找到需要替换的key：" + key);
   content = content.replace(group, params.get(key));
  }
  return content;
 }

@RestController
@RequestMapping("demo")
public class DemoController {
 @Resource
 private MSGConstatns msgConstatns;
 @RequestMapping("msg")
 public String msgContent(){
  String code = "123456";//正式开发中一般采用随机数
  Map<String,String> params = new HashMap<>();
  params.put("code",code);
  return SendCodeUtil.getContent(params,msgConstatns.getSendCodeMsg());
 }
}
