¿Cómo se mantiene una sesión en un servicio web tranquilo de primavera?

How do you maintain a session in a spring restful web service?

Steps to implement Spring Boot Session Management, which will be covered in this tutorial.

1. Create Spring Boot project from Spring Initializer.
2. Add Spring Session jdbc dependency in pom.xml.
3. Add spring jdbc properties in application.properties.
4. Create rest end points to save, destroy/invalidate session.

RESTful API endpoints should always maintain a stateless session state, meaning everything about the session must be held at the client. Each request from the client must contain all the necessary information for the server to understand the request.

By default, Spring Security will create a session when it needs one – this is “ifRequired“. For a more stateless application, the “never” option will ensure that Spring Security itself will not create any session; however, if the application creates one, then Spring Security will make use of it.

What are disadvantages of REST web services?

• Since there is no contract defined between service and client, it has to be communicated through other means such as documentation or emails.
• Since it works on HTTP, there can’t be asynchronous calls.
• Sessions can’t be maintained.

By default, web service does not support session state. For achieving high scalability, web service is designed stateless. Suppose the requirement is to use session management in a web service to retain user specific information, you need to use the session in your web service.

When session will be created it will return response header x-auth-token on the first request and while every next request x-auth-token header contains so the session will be maintained. Spring boot rest service session requires Redis store, We are assuming that Redis service is running on 6379 port: 2. Example

Configuring security for REST API in Spring In most cases, REST APIs should be accessed only by authorized parties. Spring framework provides many ways to configure authentication and authorization for an application. Another good thing is that the framework usually provides relatively good default settings.

In this article, we’re going to illustrate how Spring Security allows us to control our HTTP Sessions. This control ranges from a session timeout to enabling concurrent sessions and other advanced security configs. How to get the currently logged in user with Spring Security. Cookie Remember Me example with Spring Security.

Spring framework provides a mechanism to establish an HTTP session. If a RESTful service authenticates each request (which mostly is the case), then it doesn’t need any session management mechanism. In this case, it may be better to instruct Spring framework not to create any session:
