maven框架下添加了jersey-quickstart-webapp，如何将http请求转换为https请求？

Question

目前用maven和jersey-quickstart-webapp框架实现了http形式的get请求和post请求，已经部署到tomcat上了，利用postman验证可以传输数据，
但是项目要求不用http而是https的，该如何实现呢？
代码如下

resource core的代码

package com.ps.pcms;

import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

/**
 * Root resource (exposed at "*" path)
 */
@Path("*")
@Consumes({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
@Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
public class Core {

    /**
     * Method handling HTTP GET requests. The returned object will be sent to the
     * client as "text/plain" media type.
     *
     * @return String that will be returned as a text/plain response.
     */
    @GET
    @Path("/get")
    public String getIt(String str) {
        return "GET_SUCCESS!!\r\n" + str;
    }

    @POST
    @Path("/post")
    public String postIt(String str) {
        return "POST_SUCCESS!!\r\n" + str;
    }
}

webxml配置代码

<?xml version="1.0" encoding="UTF-8"?>
<!-- This web.xml file is not required when using Servlet 3.0 container,
     see implementation details http://jersey.java.net/nonav/documentation/latest/jax-rs.html -->

文件夹目录如下：

Answer 1

1.首先，你需要在服务器上配置 SSL 证书，并生成一个 Keystore 文件。如果你使用的是 Tomcat，可以参考官方文档中的 HTTPS 设置指南。
2.然后，在 web.xml 中添加一下内容：

<security-constraint>
    <web-resource-collection>
        <web-resource-name>Secure Webapp</web-resource-name>
        <url-pattern>/*</url-pattern>
    </web-resource-collection>
    <user-data-constraint>
        <transport-guarantee>CONFIDENTIAL</transport-guarantee>
    </user-data-constraint>
</security-constraint>

这段代码将所有请求都约束为需要保密，即 HTTPS 请求。当客户端尝试使用 HTTP 请求访问应用程序时，服务器将重定向到 HTTPS 请求。
3.将 Tomcat 中的 server.xml 文件中的 Connector 标签的 protocol 属性设置为 "org.apache.coyote.http11.Http11NioProtocol"。并添加以下属性：

<Connector port="8080" protocol="org.apache.coyote.http11.Http11NioProtocol"
           maxThreads="150" SSLEnabled="true">
    <SSLHostConfig>
        <Certificate certificateKeystoreFile="/path/to/keystore/file"
                     type="RSA" />
    </SSLHostConfig>
</Connector>

这里的 /path/to/keystore/file 根据你的具体情况替换为 SSL 证书的 Keystore 文件路径。
