如下代碼引入了spring-boot的包

package openresty;import java.io.IOException; import java.security.GeneralSecurityException; import java.security.MessageDigest; import java.util.Date; import java.util.HashMap; import java.util.Map; import java.util.Map.Entry; import java.util.Set; import java.util.TreeMap;import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication public class OpenrestySign {public static void main(String[] args) throws IOException {OpenrestySign.run(OpenrestySign.class, args);HashMap<String,String> params = new HashMap<String,String>();params.put("key", "1");params.put("a", "1");params.put("c", "w");params.put("b", "2");long time = new Date().getTime();params.put("time", "" + time);System.out.println(time);String sign = getSignature(params,"123456");System.out.println(sign);params.put("sign", sign);String resp = HttpsUtil.doGet("http://10.11.0.215/sign",params);System.out.println(resp);}/*** 簽名生成算法* @param HashMap<String,String> params 請求參數集，所有參數必須已轉換為字符串類型* @param String secret 簽名密鑰* @return 簽名* @throws IOException*/public static String getSignature(HashMap<String,String> params, String secret) throws IOException{// 先將參數以其參數名的字典序升序進行排序Map<String, String> sortedParams = new TreeMap<String, String>(params);Set<Entry<String, String>> entrys = sortedParams.entrySet();// 遍歷排序后的字典，將所有參數按"key=value"格式拼接在一起StringBuilder basestring = new StringBuilder();for (Entry<String, String> param : entrys) {if(basestring.length() != 0){basestring.append("&");}basestring.append(param.getKey()).append("=").append(param.getValue());}basestring.append("&");basestring.append(secret);System.out.println("basestring="+basestring);// 使用MD5對待簽名串求簽byte[] bytes = null;try {MessageDigest md5 = MessageDigest.getInstance("MD5");bytes = md5.digest(basestring.toString().getBytes("UTF-8"));} catch (GeneralSecurityException ex) {throw new IOException(ex);}String strSign = new String(bytes);System.out.println("strSign="+strSign);// 將MD5輸出的二進制結果轉換為小寫的十六進制StringBuilder sign = new StringBuilder();for (int i = 0; i < bytes.length; i++) {String hex = Integer.toHexString(bytes[i] & 0xFF);if (hex.length() == 1) {sign.append("0");}sign.append(hex);}return sign.toString();} }

默認直接下載spring-boot的jar包并且引入是不行的，需要新建maven的項目，通過修改pom.xml自動下載依賴
