Question

在我根据此网站https://www.thomasvitale.com/https-spring-boot-ssl-certificate/上的说明添加ssl证书后，应用程序无法启动并出现以下错误：

***************************                                                                               
APPLICATION FAILED TO START                                                                               
***************************                                                                               

Description:                                                                                              

The Tomcat connector configured to listen on port 80 failed to start. The port may already be in use or th
e connector may be misconfigured.

当我更改端口时，出现相同的错误。 netstat -ntulp显示该端口上没有正在运行的程序。当我在application.properties中与ssl关联的注释行时，服务器正常启动。请帮助我

尝试像这样配置您的后端：

添加依赖：

 implementation 'org.apache.httpcomponents:httpclient:4.5'

提供 RestTemplate bean：

@Bean
private RestTemplate restTemplate() {
        SSLContext sslContext = buildSslContext();
        SSLConnectionSocketFactory socketFactory = new SSLConnectionSocketFactory(sslContext);

        HttpClient httpClient = HttpClients.custom()
                .setSSLSocketFactory(socketFactory)
                .build();

        HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory(httpClient);

        return new RestTemplate(factory);
    }

private SSLContext buildSslContext() {
        try {
            char[] keyStorePassword = sslProperties.getKeyStorePassword();
            return new SSLContextBuilder()
                    .loadKeyMaterial(
                            KeyStore.getInstance(new File(sslProperties.getKeyStore()), keyStorePassword),
                            keyStorePassword
                    ).build();
        } catch (Exception ex) {
            throw new IllegalStateException("Unable to instantiate SSL context", ex);
        } finally {
            sslProperties.setKeyStorePassword(null);
            sslProperties.setTrustStorePassword(null);
        }
    }

在 application.properties 或 application.yaml 文件中提供所需的 SSL 属性：

server:
    ssl:
        enabled: true
        key-store: /path/to/key.keystore
        key-store-password: password
        key-alias: alias
        trust-store: /path/to/truststore
        trust-store-password: password

就是这样。现在您可以看到您的 Tomcat 正在 8080（或其他端口）（https）上启动。

或者，您可以使用 my spring boot starter
