准备
Springboot: 2.1.2.RELEASE
证书是阿里云免费证书，申请后可下载各种版本
实例
可将证书文件放置resources目录下，正式环境建议在固定目录存放
代码如下，亲测可行：
@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
...
@Bean
public ServletWebServerFactory servletContainer() {
TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory();
// 基本参数
String keyStore = "1754557_www.wbsite.xyz.pfx";
String keyStorePassword = "****";
String keyStoreType = "PKCS12";
int httpsPort = 443;
File keystore = null;
// 正常开发可以通过getFile()获取，打包jar后无法直接获取File对象，需将文件考出
try {
keystore = new ClassPathResource(keyStore).getFile();
} catch (IOException ex) {
try {
ApplicationHome home = new ApplicationHome(getClass());
// 当前运行jar文件
File jarFile = home.getSource();
//jar同目录
keystore = new File(jarFile.getParent(), keyStore);
InputStream inputStream = new ClassPathResource(keyStore).getInputStream();
byte[] bytes = new byte[inputStream.available()];
inputStream.read(bytes);
inputStream.close();
FileOutputStream fileOutputStream = new FileOutputStream(keystore);
fileOutputStream.write(bytes);
fileOutputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
// 创建Connector
Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
Http11NioProtocol protocol = (Http11NioProtocol) connector.getProtocolHandler();
connector.setScheme("https");
connector.setSecure(true);
connector.setPort(httpsPort);
protocol.setSSLEnabled(true);
protocol.setKeystoreFile(keystore.getAbsolutePath());
protocol.setKeystorePass(keyStorePassword);
protocol.setKeystoreType(keyStoreType);
// 添加
tomcat.addAdditionalTomcatConnectors(connector);
return tomcat;
}
}
