https

1. keytool 生成证书

windows下的生成:

keytool -genkey -alias tomcat -storetype PKCS12 -keyalg RSA -keysize 2048 -keystore keystore.p12 -validity 3650

linux下的命令:

keytool -genkey -alias tomcat -keyalg RSA -validity 20000 -keystore keystore.p12


执行完后会生成一个文件:keystore.p12。

关于keytool的说明:

keytool -genkey -alias 你的证书别名 -keyalg 密钥算法 -keystore 证书库文件保存的位置和文件名 -keysize 密钥长度 -validity 证书有效期天数

springboot编码

配置application.properties:

# https://127.0.0.1:8080/index.html https端口

server.port=8080

server.servlet.path=/

server.ssl.key-store=classpath:keystore.p12

server.ssl.key-store-password=123456

server.ssl.key-store-type=PKCS12

server.ssl.key-alias= tomcat

将上面生成的keystore.p12文件移动到resources下。

此时你的项目就可以使用https协议访问。

与http同时访问

如果你希望你的项目既可以http访问,也可以https访问,而且两个互不干扰:

在启动类下,加入以下代码:

springboot版本2.x:

@Bean

    public ServletWebServerFactory servletContainer() {

        TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory();

        tomcat.addAdditionalTomcatConnectors(createHTTPConnector());

        return tomcat;

    }

    private Connector createHTTPConnector() {

        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");

        connector.setScheme("http");

        connector.setSecure(false);

    // http 端口

        connector.setPort(8081);

//https 端口

        connector.setRedirectPort(8080);

        return connector;

    }

ps:注意:http的端口不要https相同,即上文的port设置,否则会出现端口占用错误。

http强制转换https访问

在用户用http访问的时候,强制转换为https。

基于上述模块与http同时访问,添加过滤器,强制重定向。

packagecom.ps.learn.socketio.filter;/**

* Created by Administrator on 2018/8/5 0005.

*/importorg.springframework.context.annotation.Configuration;importorg.springframework.web.filter.OncePerRequestFilter;importjavax.servlet.FilterChain;importjavax.servlet.ServletException;importjavax.servlet.annotation.WebFilter;importjavax.servlet.http.HttpServletRequest;importjavax.servlet.http.HttpServletResponse;importjava.io.IOException;/** * * * o *@Description*@Modify*/@Configuration@WebFilterpublicclassKindoFilterextendsOncePerRequestFilter{@OverrideprotectedvoiddoFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)throwsServletException, IOException{        String requestURL = request.getRequestURL().toString();        String protocol = requestURL.split("://")[0];        System.out.println(1111);if("http".equals(protocol)) {            requestURL = requestURL.replace("http","https").replace("8081","8080");            response.sendRedirect(requestURL);        }        filterChain.doFilter(request, response);    }}

以上是http和https共存时,http转https

若不需要共存 ,而且需要http转https,则只需要去掉过滤器,然后把之前加在启动类的代码改成一下即可

@BeanpublicServletWebServerFactoryservletContainer(){TomcatServletWebServerFactory tomcat =newTomcatServletWebServerFactory() {@OverrideprotectedvoidpostProcessContext(Context context){SecurityConstraint constraint =newSecurityConstraint();constraint.setUserConstraint("CONFIDENTIAL");SecurityCollection collection =newSecurityCollection();collection.addPattern("/*");constraint.addCollection(collection);context.addConstraint(constraint);}};tomcat.addAdditionalTomcatConnectors(createHTTPConnector());returntomcat;}privateConnectorcreateHTTPConnector(){Connector connector =newConnector("org.apache.coyote.http11.Http11NioProtocol");connector.setScheme("http");connector.setSecure(false);// http 端口connector.setPort(8081);//https端口connector.setRedirectPort(8080);returnconnector;}
