@EnableWebSecurity在春天有什么用处 [英] What is the use of @EnableWebSecurity in spring

问题描述

根据 spring docs

将此注释添加到 @配置类，通过扩展<$ c $，可以在任何 WebSecurityConfigurer 或更多
中定义Spring
安全配置c> WebSecurityConfigurerAdapter 基类和
重写单个方法：

Add this annotation to an @Configuration class to have the Spring Security configuration defined in any WebSecurityConfigurer or more likely by extending the WebSecurityConfigurerAdapter base class and overriding individual methods:

或者这个 @EnableWebSecurity 描述，用于在我们的项目中启用SpringSecurity。

Or As this @EnableWebSecurity depicts, is used to enable SpringSecurity in our project.

但我的问题是，即使我没有使用 @EnableWebSecurity 注释我的任何类，仍然是应用程序提示输入用户名和密码。（默认行为）

But my question is that even if I don't annotate any of my class with @EnableWebSecurity still the application prompting for username and password.(default behaviour)

所以我收到与 @EnableWebSecurity 相同的行为 @EnableWebSecurity 。

So I am receiving the same behaviour with @EnableWebSecurity and without @EnableWebSecurity.

有人可以解释这个注释究竟是什么？

Can someone please explain what exactly is this annotation for?

推荐答案

@EnableWebSecurity 是标记注释。它允许Spring找到（它是 @Configuration ，因此， @Component ）并自动将类应用于全局 WebSecurity 。

The @EnableWebSecurity is a marker annotation. It allows Spring to find (it's a @Configuration and, therefore, @Component) and automatically apply the class to the global WebSecurity.

如果我没有使用<注释我的任何课程code> @EnableWebSecurity 仍然是应用程序提示输入用户名和密码。

If I don't annotate any of my class with @EnableWebSecurity still the application prompting for username and password.

是的，它是默认行为。如果查看类路径，可以找到标有该注释的其他类（取决于您的依赖项）：

Yes, it is the default behavior. If you looked at your classpath, you could find other classes marked with that annotation (depends on your dependencies):

• SpringBootWebSecurityConfiguration ;


• FallbackWebSecurityAutoConfiguration ;


• WebMvcSecurityConfiguration 。

• SpringBootWebSecurityConfiguration;
• FallbackWebSecurityAutoConfiguration;
• WebMvcSecurityConfiguration.

仔细考虑它们，关闭所需的配置或覆盖其行为。

Consider them carefully, turn the needed configuration off, or override its behavior.
