java - 在 Spring Boot 2.0.4 中从 http 重定向到 https

Question

我使用 Spring boot 2.0.4。我想为所有 url 模式配置从 http 到 https 的自动重定向。我在我的 application.yml 中添加了这一行:

server:
  ssl:
    enabled: true
    key-alias: tomcat
    key-store: "classpath:tomcat.keystore"
    key-store-type: jks
    key-store-password: 123456
    key-password: 123456

然后我创建了 bean:

    @Bean
    public TomcatServletWebServerFactory httpsRedirectConfig() {
        return new TomcatServletWebServerFactory () {
            @Override
            protected void postProcessContext(Context context) {
                SecurityConstraint securityConstraint = new SecurityConstraint();
                securityConstraint.setUserConstraint("CONFIDENTIAL");
                SecurityCollection collection = new SecurityCollection();
                collection.addPattern("/*");
                securityConstraint.addCollection(collection);
                context.addConstraint(securityConstraint);
            }
        };
    }

但是，当我运行我的应用程序时，出现错误:

Caused by: org.springframework.context.ApplicationContextException: Unable to start ServletWebServerApplicationContext due to multiple ServletWebServerFactory beans : tomcatServletWebServerFactory,httpsRedirectConfig

怎么了？我该如何解决？谢谢。

尝试使用以下配置。

@Bean
public ServletWebServerFactory servletContainer() {
    TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory() {
        @Override
        protected void postProcessContext(Context context) {
            SecurityConstraint securityConstraint = new SecurityConstraint();
            securityConstraint.setUserConstraint("CONFIDENTIAL");
            SecurityCollection collection = new SecurityCollection();
            collection.addPattern("/*");
            securityConstraint.addCollection(collection);
            context.addConstraint(securityConstraint);
        }
    };
    tomcat.addAdditionalTomcatConnectors(redirectConnector());
    return tomcat;
}

private Connector redirectConnector() {
    Connector connector = new Connector(
            TomcatServletWebServerFactory.DEFAULT_PROTOCOL);
    connector.setScheme("http");
    connector.setPort(8080);
    connector.setSecure(false);
    connector.setRedirectPort(8443);
    return connector;
}
