在后端服務器中設置映射https，具體方法如下：

public class Http2HttpsConfig {
/**
* 配置服務器容器
*/
@Bean
public EmbeddedServletContainerFactory servletContainer(){
TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory(){
@Override
protected void postProcessContext(Context context) {
SecurityConstraint securityConstraint = new SecurityConstraint();
securityConstraint.setUserConstraint("CONFIDENTIAL");
SecurityCollection securityCollection = new SecurityCollection();
securityCollection.addPattern("/*");
securityConstraint.addCollection(securityCollection);
context.addConstraint(securityConstraint);
}
};
tomcat.addAdditionalTomcatConnectors(httpConnector());
return tomcat;
}
/**
* 設置http到https的url映射
*/
@Bean
public Connector httpConnector(){
Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
connector.setScheme("http");
connector.setPort(8080);
connector.setSecure(false);
connector.setRedirectPort(8088);
return connector;
}
}
