What is Spring Cloud Square When talking about Spring Cloud ecology, you must be familiar with Feign. As shown in the figure below, Feign can hide the Rest requests of the underlying (okhttp, httpclient) and pretend to be similar to the Controller of spring MVC. You don't have to splice URLs, splice parameters and other operations by yourself. ...

Today, let's take a look at how fast the native executable built by Quarkus can be faster than the Spring application. The maturity of ecology is not discussed here. TLDR First, let's draw a conclusion and make a comparison with the Spring Web application with only one Controller. Application start time: 0.012s vs 2.294s ...

Getting started with Spring MVC The first layer is the web browser, and the second layer is the web browser, which is used to learn about the various web application transmission protocols. The first layer is the web browser, and the second layer is used to learn about these web application transmission protocols. HTTP protocol First, lear ...

Since the videos in Silicon Valley are made by Eclipse software, some of which are different from IDEA, I'm here to share with you the differences between IDEA and Eclipse's operation, the source code involved in the operation (slightly different from the source code of the video), and the various problems you may encounter. These sources are t ...

1. Circular dependency resolution in the case of prototype Bean First of all, Spring will not scan prototype beans in the scanning phase. These prototype beans will be created only when called. List several scenarios for prototype beans to briefly describe: (1) Suppose there are two objects, class A and class B, and both are defined as pro ...

shiro (java security framework) 1 Introduction Apache Shiro is a security framework for Java. At present, more and more people use Apache Shiro because it is quite simple. Compared with Spring Security, it may not be as powerful as Spring Security, but it may not need so complex things in actual work, so using a small and simple Shiro is enou ...
