您好? 這兩個(gè)方法該寫(xiě)在哪個(gè)類(lèi)中呢

我找到了一個(gè)方法，親測(cè)有效的：

寫(xiě)一個(gè)server ?然后啟動(dòng)一個(gè)線程，線程里面定義一個(gè)全局靜態(tài)變量，線程定時(shí)運(yùn)行獲取access_token，然后放到內(nèi)存中，取的時(shí)候通過(guò)這個(gè)靜態(tài)變量取就可以了。

jar包自己找吧

servlet----------
public?class?InitServlet?extends?HttpServlet?{????
????private?static?final?long?serialVersionUID?=?1L;????
????private?static?Logger?log?=?LoggerFactory.getLogger(WeixinUtil.class);
???
????public?void?init()?throws?ServletException?{????
????????//?獲取web.xml中配置的參數(shù)?，并初始化TokenThread.java中靜態(tài)變量appid和appsecret
????????TokenThread.appid?=?getInitParameter("appid");????
????????TokenThread.appsecret?=?getInitParameter("appsecret");
????????
????????//?web.xml未配置appid、appsecret時(shí)給出提示????
????????if?("".equals(TokenThread.appid)?||?"".equals(TokenThread.appsecret))?{????
????????????log.error("請(qǐng)?jiān)趙eb.xml的InitServlet中設(shè)置appid、appsecret參數(shù)");?
????????}?else?{
????????????//?啟動(dòng)定時(shí)獲取access_token的線程????
????????????new?Thread(new?TokenThread()).start();
????????}????
????}????
}
注意在web.xml配置參數(shù)appid?，appsecret

線程=-----------
public?class?TokenThread?implements?Runnable?{
	private?static?Logger?log?=?LoggerFactory.getLogger(TokenThread.class);
	//?第三方用戶(hù)唯一憑證,從InitServlet中賦值
	public?static?String?appid?=?"";
	//?第三方用戶(hù)唯一憑證密鑰，從InitServlet中賦值
	public?static?String?appsecret?=?"";
	public?static?AccessToken?accessToken?=?null;
	public?void?run(){
		/**
		?*定期獲取token
		?*/
		while?(true)?{
			try?{
				//調(diào)用公眾平臺(tái)接口獲取access_token；
				accessToken?=?WeixinUtil.getAccessToken(appid,appsecret);
				if?(null?!=?accessToken)?{
					log.info("獲取access_token成功，有效時(shí)長(zhǎng){}秒?token:{}",?accessToken.getExpiresIn(),?accessToken.getToken());
					//?休眠7000秒??
					Thread.sleep((accessToken.getExpiresIn()?-?200)?*?1000);
				}?else?{
					//?如果access_token為null，60秒后再獲取
					Thread.sleep(60?*?1000);
				}
			}?catch?(InterruptedException?e)?{
				try?{
					Thread.sleep(10?*?1000);
				}?catch?(InterruptedException?e1)?{
					System.out.println();
				}
				System.out.println();
			}
		}
	}
}


其他類(lèi)中取值：String?token?=?TokenThread.accessToken.getToken();
