pringBoot2.0启用https协议

SpringBoot2.0之后，启用https协议的方式与1.*时有点儿不同，贴一下代码。

　　我的代码能够根据配置参数中的condition.http2https，确定是否启用https协议，如果启用https协议时，会将所有http协议的访问，自动转到https协议上。

一、启动程序

1. package com.wallimn.iteye.sp.asset;
2. import org.apache.catalina.Context;
3. import org.apache.catalina.connector.Connector;
4. import org.apache.tomcat.util.descriptor.web.SecurityCollection;
5. import org.apache.tomcat.util.descriptor.web.SecurityConstraint;
6. import org.springframework.beans.factory.annotation.Value;
7. import org.springframework.boot.SpringApplication;
8. import org.springframework.boot.autoconfigure.SpringBootApplication;
9. import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
10. import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
11. import org.springframework.context.annotation.Bean;
12. /**
13. * SpringBoot2.0启动程序
14. * @author wallimn，http://wallimn.iteye.com
15. *
16. */
17. @SpringBootApplication
18. public class AssetApplication {
19. public static void main(String[] args) {
20. SpringApplication.run(AssetApplication.class, args);
21. }
22. //如果没有使用默认值80
23. @Value("${http.port:80}")
24. Integer httpPort;
25. //正常启用的https端口 如443
26. @Value("${server.port}")
27. Integer httpsPort;
28. // springboot2 写法
29. @Bean
30. @ConditionalOnProperty(name="condition.http2https",havingValue="true", matchIfMissing=false)
31. public TomcatServletWebServerFactory servletContainer() {
32. TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory() {
33. @Override
34. protected void postProcessContext(Context context) {
35. SecurityConstraint constraint = new SecurityConstraint();
36. constraint.setUserConstraint("CONFIDENTIAL");
37. SecurityCollection collection = new SecurityCollection();
38. collection.addPattern("/*");
39. constraint.addCollection(collection);
40. context.addConstraint(constraint);
41. }
42. };
43. tomcat.addAdditionalTomcatConnectors(httpConnector());
44. return tomcat;
45. }
46. @Bean
47. @ConditionalOnProperty(name="condition.http2https",havingValue="true", matchIfMissing=false)
48. public Connector httpConnector() {
49. System.out.println("启用http转https协议，http端口："+this.httpPort+"，https端口："+this.httpsPort);
50. Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
51. connector.setScheme("http");
52. //Connector监听的http的端口号
53. connector.setPort(httpPort);
54. connector.setSecure(false);
55. //监听到http的端口号后转向到的https的端口号
56. connector.setRedirectPort(httpsPort);
57. return connector;
58. }}

二、配置文件

1.使用http协议时的配置 
server.port=80

2.使用https及http协议时的配置 
server.port=443 
server.ssl.key-store=classpath:keystore.p12 
server.ssl.key-store-password=your-password 
server.ssl.keyStoreType=PKCS12 
server.ssl.keyAlias=your-cert-alias 
condition.http2https=true 
http.port=80
