java 字符串解析操作

// TestObject s = savedContext.get("user_id");Object s1 = savedContext.get("topic");Object s2 = savedContext.get("app_key");// 取不到，在串里// 判断是否为空String s3 = savedContext.get("httpQuery").toString();StringTokenizer fenxi = new StringTokenizer(s3, "&"); // 用&分割解析String str = null;while (fenxi.hasMoreTokens()) {str = fenxi.nextToken();if (str.indexOf("app_key") != -1) {// 拿到包含app_key的串break;}}String a[] = str.split("=");// 用=分割// 都要判断，为空返回String xx = a[0];// app_key 的 keyString xx1 = a[1];// app_key的value// Test
