How SpringBoot implements api encryption

In the SpringBoot API encryption docking project, in order to ensure data security, we often encrypt the transmitted data. Commonly used encryption algorithms include symmetric encryption (AES) and asymmetric encryption (RSA). The blogger selected the simplest API encryption project on Code Cloud for the following explanation. Below is an introduction to our brightest project, the rsa-encrypt-body-spring-boot project. This project uses RSA encryption to encrypt the data returned by the API interface, making the API data more secure. Others cannot decipher the data provided. SpringBoot interface encryption can automatically encrypt and decrypt return values and parameter values through annotations. What is RSA encryption first me

How does SpringBoot select me first when loading beans?

1. Applicable scenarios If we need to manage the startup sequence of specific beans in all hierarchies of the application. For example, you need to initialize a bean when the application starts. If the beans in our public library are used by other developer services, but they need to customize beans in some scenarios, we need to load the beans in the public library before these customized beans. 2. Three implementation methods In SpringBoot applications, we can adopt the following three methods to achieve priority loading of our own beans: 1. @Configuration annotation + @DependsOn annotation @Configuration annotation in SpringBoo

How to build springboot project in idea

SpringBoot is a new framework provided by the Pivotal team. It is designed to simplify the initial construction and development process of new Spring applications. What it mainly advocates is 'eliminating configuration' and achieving zero configuration. So, how to create a springboot project in idea? 1. Create a Module under the project you created and select Springinitializr to create it. 2. Select MavenProject (the project's construction tool) at Type. 3. When creating dependencies, check web, mybatis, and mysql (this depends on your personal needs, you can choose independently). The established project structure is as follows:

How to set springboot startup port

Springboot is a good thing. It can be started directly in the main method without a container, and no configuration file is required, making it easy to quickly build an environment. But when we want to start two springboot projects at the same time, there will be a problem. The second application may not be started because port 8080 is occupied by the first application. In this case, we need to modify the startup port of one of the projects. This can be achieved by implementing the EmbeddedServletContainerCustomizer interface: publicclassApplicationextendsSpringBootServletInitializerimplements

How to use Spring MVC in Spring Boot

1.MVCMVC is a common software design pattern used to separate different parts of an application to achieve loose coupling and high cohesion. The MVC pattern consists of three core components: Model: represents the data and business logic of the application. The model processes the application's data and performs corresponding operations based on the controller's instructions. View: Provides a user interface for model data. Views are usually templates, HTML pages, XML files, or other formats that can present model data to users. Controller: Handles user interaction and updates models and views. The controller is responsible for receiving user input from the view, performing corresponding operations on the model, and updating the view to reflect the changes. MVC pattern

Method for parameter verification in Spring Boot project

Scenario restoration Simple business scenario simulation: If you are currently working on a score entry system, you happily write a backend interface using the SpringBoot framework to receive the Student object passed from the frontend browser and insert it into the backend database. We define the incoming Student object as: publicclassStudent{privateStringname;//Name privateIntegerscore;//Examination score (out of 100 points) privateStringmobile;//Phone number (11 digits)} Then write a background interface for Post requests to receive Student object passed from the web page:

How spring boot integrates redisson

Integration and precautions redisson supports redis environment, stand-alone, cluster, sentinel, cloud, etc. Here I will talk about what you need to pay attention to in the cluster mode. Redisson will detect whether the master/slave node is normal when it is started. Generally speaking, there is no problem with 3 shards, 3 masters and 3 slaves. However, if the test environment has 1 shard, 1 master and 1 slave, or None of the 3 masters can be started. In addition to the environment, you also need to pay attention to compatibility with or without passwords. Manually inject the redisson configuration. Generally, the production environment has a password. If there is a password, it is recommended to manually inject the redisson configuration without using springboot to help you integrate it, because springboot may not be able to recognize the password.

What is the method for SpringBoot to integrate tomcat?

Springboot supports the current mainstream servlet containers, including tomcat, jetty, and undertow. These servlet containers can be easily integrated into our projects, reducing the workload of development and operation and maintenance. Traditional application development requires complicated steps: install tomcat->modify tomcat configuration->deploy war package->start tomcat->operation and maintenance... This workload is not small, especially cluster deployment and application migration.

How to use multi-threading of scheduled tasks @Scheduled in SpringBoot

1. Introduction to @Scheduled annotation @Scheduled is an annotation in the Spring framework. It can be used to configure scheduled tasks so that methods can be executed regularly according to specified time intervals. When using this annotation, we can specify the execution time, cycle period, number of concurrency and other parameters of the task to realize the function of scheduled tasks. In SpringBoot, the @Scheduled annotation can be applied directly to methods. 2. The multi-threading mechanism of @Scheduled In SpringBoot, the @Scheduled annotation is based on Java's ThreadPoolExecutor and ScheduledThreadPoolExec

How to solve SpringBoot @Componet annotation injection failure

@Componet annotation injection failure problem description: When writing a springboot program, the @Component annotation is clearly added to the Person class, but the container shows that the Bean object of the Person class cannot be found. I searched for many conventional solutions on the Internet, but found that none of them worked. Later I realized that it might be a problem with package scanning. Since my main program at that time was placed in a folder with the same name as the main program, according to the default package scanning rules – scan For classes in the package where the main program is located and all its sub-packages, the Person class under the domain package will naturally not be scanned, so although @Component is marked, it will not take effect. The solution is to add Co on the main program
