java Spring Boot：从 url 中删除 jsessionid

Spring Boot: remove jsessionid from url

提问by Kian

How can I remove the jsessionid from my urls?

如何从我的网址中删除 jsessionid？

I'm using Spring Boot MVC (without Spring Security; tomcat embedded).

我正在使用 Spring Boot MVC（没有 Spring Security；嵌入了 tomcat）。

I've read that It could be done by setting the disableUrlRewriting to "true". But this looks like a Spring Security solution, which I don't use (it's a simple project without login; just pages; a session-controller exists and has to be a session-controller).

我读过可以通过将 disableUrlRewriting 设置为“true”来完成。但这看起来像一个 Spring Security 解决方案，我不使用它（这是一个没有登录的简单项目；只是页面；会话控制器存在并且必须是会话控制器）。

I'm asking this because GoogleBot is creating urls containing the id.

我问这个是因为 GoogleBot 正在创建包含 id 的网址。

EDIT: I solved it with the solution described at: https://randomcoder.org/articles/jsessionid-considered-harmful

I created a quick-and-dirty spring-boot app and here's what I came up with.

我创建了一个快速而肮脏的 spring-boot 应用程序，这就是我想出的。

The ServletInitializer that is generated, you can alter it in this fashion:

生成的 ServletInitializer，您可以以这种方式更改它：

package com.division6.bootr;

import java.util.Collections;

import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.SessionCookieConfig;
import javax.servlet.SessionTrackingMode;

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        // This can be done here or as the last step in the method
        // Doing it in this order will initialize the Spring
        // Framework first, doing it as last step will initialize
        // the Spring Framework after the Servlet configuration is 
        // established
        super.onStartup(servletContext);

        // This will set to use COOKIE only
        servletContext
            .setSessionTrackingModes(
                Collections.singleton(SessionTrackingMode.COOKIE)
        );
        // This will prevent any JS on the page from accessing the
        // cookie - it will only be used/accessed by the HTTP transport
        // mechanism in use
        SessionCookieConfig sessionCookieConfig=
                servletContext.getSessionCookieConfig();
        sessionCookieConfig.setHttpOnly(true);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SpringBootrApplication.class);
    }

}

I am not 100% sure when this was introduced but by introducing the following parameters, the same can be accomplished without having to write code:

我不是 100% 确定这是何时引入的，但是通过引入以下参数，无需编写代码即可完成相同的操作：

• server.servlet.session.cookie.http-only=true
• server.servlet.session.tracking-modes=cookie

• server.servlet.session.cookie.http-only=true
• server.servlet.session.tracking-modes=cookie

As this question is in spring boot context, easy solution for me was:

由于这个问题是在 spring boot 上下文中，对我来说简单的解决方案是：

server:
  session:
    tracking-modes: cookie

Added in appication.yml it modifies embedded tomcat config. From list of ll spring boot properties: https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#common-application-properties

在 appication.yml 中添加它修改嵌入式 tomcat 配置。从 ll spring boot 属性列表：https: //docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#common-application-properties

you can also try this,

你也可以试试这个

        @Bean
            public ServletContextInitializer servletContextInitializer() {
                return new ServletContextInitializer() {

                    @Override
                    public void onStartup(ServletContext servletContext) throws ServletException {
                       servletContext.setSessionTrackingModes(Collections.singleton(SessionTrackingMode.COOKIE));
                       SessionCookieConfig sessionCookieConfig=servletContext.getSessionCookieConfig();
                       sessionCookieConfig.setHttpOnly(true);
                    }
                };

        }

More portable option which also works for non-SpringBoot, add the following to the webapp's web.xml:

更便携的选项也适用于非 SpringBoot，将以下内容添加到 webapp 的web.xml:

<session-config>
    <tracking-mode>COOKIE</tracking-mode>
</session-config>
