@CrossOrigin(allowCredentials = "true")

@CrossOrigin(allowCredentials = "true")是一个注解，用于在Spring Boot中处理跨域请求时设置是否允许携带cookie。根据引用\[1\]和引用\[2\]的内容，如果使用的是Spring Boot 2.0及以后的版本，默认情况下allowCredentials属性的值为false，这意味着返回的响应头AccessControlAllowCredentials属性值也为false，如果客户端携带cookie的请求将无法进行跨域访问。因此，需要手动在注解中设置allowCredentials为true，即@CrossOrigin(allowCredentials = "true")，以允许跨域请求携带cookie。这种方式适用于只有一两个REST接口需要跨域或者没有网关的情况下，修改影响较小。\[1\]\[2\]\[3\]
