Spring Boot中启动HTTPS
如果你使用Spring Boot,并且想在内嵌tomcat中添加HTTPS,需要如下步骤
- 要有一个证书,买的或者自己生成的
- 在Spring Boot中启动HTTPS
- 将HTTP重定向到HTTPS(可选)
获取SSL证书
有两种方式
- 自己通过keytool生成
- 通过证书授权机构购买
这里作为演示,采用keytool生成
输入下面的命令,根据提示输入信息
keytool -genkey -alias tomcat -storetype PKCS12 -keyalg RSA -keysize 2048 -keystore keystore.p12 -validity 3650Enter keystore password:Re-enter new password:What is your first and last name?[Unknown]:What is the name of your organizational unit?[Unknown]:What is the name of your organization?[Unknown]:What is the name of your City or Locality?[Unknown]:What is the name of your State or Province?[Unknown]:What is the two-letter country code for this unit?[Unknown]:Is CN=Unknown, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=Unknown correct?[no]: yes123456789101112131415161718复制代码
会生成一个PKCS12格式的叫做keystore.p12的证书,之后启动Spring Boot时会引用这个证书
Spring Boot 中开启HTTPS
默认情况下Spring Boot内嵌的Tomcat服务器会在8080端口启动HTTP服务,Spring Boot允许在application.properties中配置HTTP或HTTPS,但是不可同时配置,如果两个都启动,至少有一个要以编程的方式配置,Spring Boot官方文档建议在application.properties中配置HTTPS,因为HTTPS比HTTP更复杂一些,可以参考spring-boot-sample-tomcat-multi-connectors的实例
在application.properties中配置HTTPS
server.port: 8443server.ssl.key-store: classpath:keystore.p12server.ssl.key-store-password: mypasswordserver.ssl.keyStoreType: PKCS12server.ssl.keyAlias: tomcat12345复制代码
这就够了
将HTTP请求重定向到HTTPS(可选)
让我们的应用支持HTTP是个好想法,但是需要重定向到HTTPS,上面说了不能同时在application.properties中同时配置两个connector,所以要以编程的方式配置HTTP connector,然后重定向到HTTPS connector
这需要在配置类中配置一个TomcatEmbeddedServletContainerFactory bean,代码如下
@Bean public EmbeddedServletContainerFactory servletContainer() { TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory() { @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(initiateHttpConnector()); return tomcat; } private Connector initiateHttpConnector() { Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol"); connector.setScheme("http"); connector.setPort(8080); connector.setSecure(false); connector.setRedirectPort(8443); return connector; }1234567891011121314151617181920212223242526272829复制代码
搞定!
