How to implement Redis multi-level cache based on Java

1. Multi-level caching 1. After the request of the traditional caching scheme reaches tomcat, it first goes to redis to get the cache. If there is no hit, it goes to mysql to get it. 2. The number of concurrent requests of multi-level caching scheme tomcat is much smaller than that of redis, so tomcat will Become a bottleneck and use each link of request processing to add cache respectively to reduce the pressure on tomcat and improve service performance. 2. The JVM local cache cache is stored in the memory. The data reading speed is faster, which can greatly reduce the access to the database and reduce the pressure on the database. Distributed cache, such as redis - Advantages: Large storage capacity, good reliability, can be shared in the cluster - Disadvantages: There is network overhead for accessing the cache - Scenario: Large amount of cached data, high reliability, needs to be in the cluster

How to deploy tomcat and Nginx on linux server

1. Preparation work: First of all, you must have a Linux server that can be played, and know the user name and password. Then you need to install two tools on the Windows computer that can connect to the Linux server, xshell5 and xftp5. I will not go into the installation tutorial. I will add a picture. Explain how to connect to the server: The xshell connection interface is as follows. After entering the host IP and click OK, xshell will pop up a window to enter the user name and password to connect successfully! The xftp connection interface is as follows. Just fill in the blanks. It’s very simple. I won’t go into details. I’d like to mention why sftp is chosen instead of ftp here. You’ll understand if you know how much you know about the difference between ftp and sftp! 2. Installation and deployment work If you want to deploy the project to

How to encapsulate the startup entry of SpringBoot application

Springboot can be said to be an essential skill for Java programmers. Everyone knows that Springboot can eventually be packaged into a jar package through maven, and then directly use the java-jar command to run a web project (or other). This avoids the complicated operations of the original tomcat-based web project. Springboot can make the deployment of Web services so simple because it has a built-in Jetty (or Tomcat) server, and starts the server during the container startup process to successfully run the Web service. I believe that all Springbooters will be familiar with the following code, whether they are new students learning Springboot,

How springboot handles compression requests

Springboot's processing of compression requests has recently been aligned with UnionPay's requirements. In order to save bandwidth, messages need to be compressed. But using the compression settings that come with springboot does not work: server.compression.enabled=trueserver.compression.mime-types=application/javascript,text/css,application/json,application/xml,text/html,text/xml, text/plainserver.compression.comp

How to configure Nginx SSL certificate to achieve HTTPS access

Background Due to project requirements and security reasons, it is necessary to change the previous http interface access to https access, so an SSL certificate needs to be configured. The architecture of the project is like this: the basic architecture is hard load (readwhere) + soft load (nginx) + tomcat cluster. The question now is where to configure the SSL certificate, directly on the hard load? Or configure it on nginx and tomcat respectively? Or is there any other configuration method? First, I gave up configuring the hard load, and then after searching for information on the Internet, I found that the certificate can be configured only on nginx, which means that nginx uses https for access, and nginx and tomcat use http for connection, so that the game

Springboot's built-in tomcat prohibits unsafe HTTP methods 1. In tomcat's web.xml, you can configure the following content to make tomcat prohibit unsafe HTTP methods/*PUTDELETEHEADOPTIONSTRACEBASIC2. Springboot uses the built-in tomcat without a web.xml configuration file, which can be configured through the following, To put it simply, it is to be injected into the Spring container @ConfigurationpublicclassTomcatConfig{@BeanpublicEmbeddedServletContainerFacto

Analysis of unsafe decompression GetShell instances discovered through traceability

Recently, when we helped a client trace an intrusion incident, we discovered that the hacker used the website's "ZIP decompression function" to upload a Webshell before gaining access to the server. Because this leakage exploitation method is relatively representative in terms of "attack payload structure" and "actual decompression path", and the industry still does not pay enough attention to the "unsafe decompression" vulnerability. Therefore, we wrote this report, in which we explain the process of intrusion tracing and vulnerability discovery, and put forward some security suggestions from the two dimensions of security development and security dog product protection solutions, hoping to benefit the industry. It is worth noting that although the CMS has made relevant defense configurations, if you directly write the JSP file in the root directory of the CMS, it will not be executed and a 403 error will be reported.

Kindediter is used to better demonstrate image uploading, echoing, and batch effects. The background code is not directly related to kindediter, so feel free to read it. In addition, there is a mybatis jar in the source code, so don’t pay attention to it. The content of this chapter is not used. It is to prepare for the subsequent content!
