Spring Security CORS：来源已被 CORS 策略阻止

Question

我在 Angular 项目中第一次使用 Spring Boot，在添加 Spring 安全依赖项之前一切正常

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-test</artifactId>
    <scope>test</scope>
</dependency>

现在我在客户端收到此错误：

Access to XMLHttpRequest at 'http://localhost:8080/api/v1/login' from origin 'http://localhost:4200' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status.

我尝试按照文档的建议更改配置，所以我添加了类

src/main/java/com/example/securingweb/WebSecurityConfig.java

@Configuration
@EnableWebMvc
public class WebConfig implements WebMvcConfigurer{

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**");
    }
}

我的控制器中也有这个：

@CrossOrigin(origins = "http://localhost:4200")

由于您添加了 Spring 安全依赖项，因此 Spring 将启用 Basic Auth，这将验证您的每个请求。这也启用了 CORS（跨源请求共享）。尽管您为每个不足以禁用 CORS 的请求添加了 CrossOrigin。

所以要么您需要发送将在您的控制台上打印的 Spring Security 生成的令牌

或

您需要配置 Spring 安全配置类，该类将验证您的身份验证或允许特定的 url。
