输入文字（支持中英文），点击转换生成***.wav文件，点击下载到本地就可。
生成后的音频文件播放,时长1分8秒
这次采用jacob实现，相比百度AI需要联网，本项目定位内网环境实现。所以最终采jacob。
本次采用版本jacob-1.19，我们需要下载jacob.jar和dll
下载地址：jacob语音生成文件，jacobx64.dll和jacob.jar为1.9-Java文档类资源-CSDN下载
官网地址：JACOB - Java COM Bridge download | SourceForge.net
下载后得到两个文件：
jacob.dll：配置到jdk环境中
jacob.jar：放入到项目中并配置下pox和Idea 的dependencies下
第一步：
jacob.dll放入：C:\Program Files\Java\jdk1.8.0_121\jre\bin
第二步：
1.首先有一个spring boot项目，没有就搭建一个
2.把jacob放到项目resources>lib目录下
3.在pom.xml文件添加依赖：
<!--添加本地的jacob.jar包-->
<dependency>
<groupId>com.jacob</groupId>
<artifactId>jacob</artifactId>
<version>1.19</version>
<!--system使用本地jar包-->
<scope>system</scope>
<systemPath>${basedir}/src/main/resources/lib/jacob.jar</systemPath>
</dependency>4.在idea下的项目中添加依赖包，
5.这样环境就搭建完成。
核心代码，这样就可以输入文字，生成音频文件保存到本地目录中，然后下载音频文件就只需要读取文件就可以。
//输入文本内容，生成文件地址 text为输入的文本信息
public void audioFile(String text){
try {
//jacob.dll没成功安装，执行这一步会出错
//构建音频格式 调用注册表应用
Dispatch spAudioFormat = new ActiveXComponent("Sapi.SpAudioFormat").getObject();
//音频文件输出流
Dispatch spFileStream = new ActiveXComponent("Sapi.SpFileStream").getObject();
//构建音频对象
Dispatch spVoice = new ActiveXComponent("Sapi.SpVoice").getObject();
//设置spAudioFormat音频流格式类型22
Dispatch.put(spAudioFormat, "Type", new Variant(22));
//设置spFileStream文件输出流的音频格式
Dispatch.putRef(spFileStream, "Format", spAudioFormat);
//设置spFileStream文件输出流参数地址等
Dispatch.call(spFileStream, "Open", new Variant("D:\speech\48641486.wav"), new Variant(3), new Variant(true));
//设置spVoice声音对象的音频输出流为输出文件对象
Dispatch.putRef(spVoice, "AudioOutputStream", spFileStream);
//设置spVoice声音对象的音量大小100
Dispatch.put(spVoice, "Volume", new Variant(100));
//设置spVoice声音对象的速度 0为正常速度，范围【..-2 -1 0 1 2..】
Dispatch.put(spVoice, "Rate", new Variant(0));
//设置spVoice声音对象中的文本内容
Dispatch.call(spVoice, "Speak", new Variant(text));
//关闭spFileStream输出文件
Dispatch.call(spFileStream, "Close");
//释放资源
spVoice.safeRelease();
spAudioFormat.safeRelease();
spFileStream.safeRelease();
}catch (Exception e){
System.out.println(e.getMessage());
}

通过上面的几个文件代码，就可以实现文章前面web页面的效果了。
本文章只是一个demo演示。应用到具体业务中还需要做一些修改。
