springboot如何将http转https
一、安全证书的生成
可以使用jdk自带的证书生成工具，jdk自带一个叫keytool的证书管理工具，可以用它来实现签名的证书。
1、进入cmd命令控制终端
2、生成一个证书
别名：alias = tomcat
密码：keypass = 123456
生成位置：keystore = D:/keys
keys文件夹需要自己先创建好
cmd命令:
keytool -genkey -alias tomcat -keypass 123456 -keyalg RSA -keysize 1024 -validity 365 -keystore D:/keys/tomcat.keystore -storepass 123456
3、获取tomcat.keystore文件，放入项目根目录下面
二，配置yml文件
- server:
- port: 8443
- ssl:
- key–store: server.keystore
- key–alias: tomcat
- enabled: true
- key–store–type: JKS
- key–store–password: 123456
三、springbootApplication启动类配置
- import org.apache.catalina.Context;
- import org.apache.catalina.connector.Connector;
- import org.apache.tomcat.util.descriptor.web.SecurityCollection;
- import org.apache.tomcat.util.descriptor.web.SecurityConstraint;
- import org.springframework.boot.SpringApplication;
- import org.springframework.boot.autoconfigure.SpringBootApplication;
- import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
- import org.springframework.boot.web.servlet.server.ServletWebServerFactory;
- import org.springframework.context.annotation.Bean;
- @SpringBootApplication
- public class WeijingApplication {
- public static void main(String[] args) {
- SpringApplication.run(WeijingApplication.class, args);
- }
- @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(“org.apache.coyote.http11.Http11NioProtocol”);
- connector.setScheme(“http”);
- connector.setPort(8080);
- connector.setSecure(false);
- connector.setRedirectPort(8443);
- return connector;
- }
启动成功
另外：springboot2.xx版本以上可以用上面的方法 如果2.xx以下的 就要换成
EmbeddedServletContainerFactory
- import org.apache.catalina.Context;
- import org.apache.catalina.connector.Connector;
- import org.apache.tomcat.util.descriptor.web.SecurityCollection;
- import org.apache.tomcat.util.descriptor.web.SecurityConstraint;
- import org.springframework.boot.SpringApplication;
- import org.springframework.boot.autoconfigure.SpringBootApplication;
- import org.springframework.context.annotation.Bean;
- @SpringBootApplication
- public class WeijingApplication {
- public static void main(String[] args) {
- SpringApplication.run(WeijingApplication.class, args);
- }
- @Bean
- public EmbeddedServletContainerFactory servletContainer() {
- TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory() {
- @Override
- protected void postProcessContext(Context context) {
- SecurityConstraint constraint = new SecurityConstraint();
- constraint.setUserConstraint(“CONFIDENTIAL”);
- SecurityCollection collection = new SecurityCollection();
- collection.addPattern(“/*”);
- constraint.addCollection(collection);
- context.addConstraint(constraint);
- }
- };
- tomcat.addAdditionalTomcatConnectors(httpConnector());
- return tomcat;
- }
- @Bean
- public Connector httpConnector() {
- Connector connector = new Connector(“org.apache.coyote.http11.Http11NioProtocol”);
- connector.setScheme(“http”);
- //Connector监听的http的端口号
- connector.setPort(8080);
- connector.setSecure(false);
- //监听到http的端口号后转向到的https的端口号
- connector.setRedirectPort(8443);
- return connector;
- }
另外：报错端口被占用的话可以看下这个
报错是因为不能读取配置文件的端口，那个端口是要被用的
部署到linux服务器 https启动失败报错 原因：
部署到服务器的时候 需要用再linux服务器上面 重新用Linux的JDK生成证书 (不能用Windows生成的证书) 并放再固定的文件夹位置
更改yml文件配置
更改成服务器文件夹路径：/usr/local/xxx/server.keystore
