1.证书申请（自行选购）
2.下载证书
3.解压下载压缩包
4.将.pfx文件放至springboot项目resources目录下
applicatio.yml中添加配置
5.设置http自动重定向https（8082端口->443端口）：
在SpringApplication启动类中加入以下代码：(注意网上有些代码中的EmbeddedServletContainerFactory找不到是因为springboot2.X之后改了写法)
//拦截所有请求
@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(httpConnector());
return tomcat;
}
//配置http转https
@Bean
public Connector httpConnector() {
Connector connector = new Connector(TomcatServletWebServerFactory.DEFAULT_PROTOCOL);
connector.setScheme("http");
//Connector监听的http的端口号
connector.setPort(8082);
connector.setSecure(false);
//监听到http的端口号后转向到的https的端口号
connector.setRedirectPort(443);
return connector;
}
