由于公司接到的项目环境不允许联网，这边通过不停的探索，终于找到通过JNA的方式接入，废话不多说，下面展示！

1、讯飞开放平台SDK下载

2、JNA包依赖引入

<!-- https://mvnrepository.com/artifact/net.java.dev.jna/jna -->
         <dependency>
             <groupId>net.java.dev.jna</groupId>
             <artifactId>jna</artifactId>
             <version>5.5.0</version>        </dependency>

3、 JAVA代码（将此代码直接贴上去）

注：需要修改appid = 577xxxxx中的参数，改成你自己的appid（因为讯飞平台会识别你下载的sdk和你的appid是否一致）

public class XunFeiSpeech {

    public interface MscLibrary extends Library {

        // DLL文件默认路径为项目根目录，若DLL文件存放在项目外，请使用绝对路径
        MscLibrary INSTANCE = Native.load("lib\\msc_x64.dll", MscLibrary.class);

        int MSPLogin(String username, String password, String param);

        int MSPLogout();

        String QTTSSessionBegin(String params, IntByReference errorCode);

        int QTTSTextPut(String sessionID, String textString, int textLen, String params);

        Pointer QTTSAudioGet(String sessionID, IntByReference audioLen, IntByReference synthStatus, IntByReference errorCode);

        int QTTSSessionEnd(String sessionID, String hints);
    }

    public static void main(String[] args) {

		//登录参数,appid与msc库绑定,请勿随意改动
        String login_params = "appid = 577xxxxx, work_dir = .";
        //合成参数：tts_res_path我这里用了绝对路径
        String session_begin_params = "engine_type = local, voice_name = xiaoyan, text_encoding = UTF-8, tts_res_path = fo|C:\\Users\\96248\\Desktop\\demo\\XunFeiSpeech\\lib\\xiaoyan.jet;fo|C:\\Users\\96248\\Desktop\\demo\\XunFeiSpeech\\lib\\common.jet, sample_rate = 16000, speed = 50, volume = 50, pitch = 50, rdn = 2";
        //合成的语音文件名称
        String filename = "tts_sample.wav"; 
         //合成文本
        String text = "《出师表》是三国时期蜀汉丞相诸葛亮在决定北上伐魏、克复中原 [2]  之前给后主刘禅上书的表文。 [1]  [3]  [20]  这篇表文以议论为主，兼用记叙和抒情。全文以恳切委婉的言辞劝勉后主要广开言路、严明赏罚、亲贤远佞，以此兴复汉室 还于旧都（洛阳） [2]  [4]  ；同时也表达自己以身许国，忠贞不二的思想。文章既不借助于华丽的辞藻，又不引用古老的典故，多以四字句行文。 [5]";

        String sessionId = null;

        try {
            //登录
            int loginCode = MscLibrary.INSTANCE.MSPLogin(null, null, login_params);

            if (loginCode != 0) {
                //登录失败
                return;
            }

            //初始session
            IntByReference errCode = new IntByReference();
            sessionId = MscLibrary.INSTANCE.QTTSSessionBegin(session_begin_params, errCode);

            if (errCode.getValue() != 0) {
                //会话失败
                return;
            }

            //放入文本

                return;

            //定位到文件起始位置
            raf.seek(0);
            //写入真实头格式
            raf.write(getWavHeader(dataSize, 16000, 32000, 1, 16));
