尝试 解决 我 的 应用 程序 中 的 CORS 问题 。 在 Spring 文档 中 , 我 通过 设置 Csconfigurationsource 找到 了 问题 的 解决 方案 。 但 在 将 核心 配置 源 bean 添加 到 SecurityConfig 类 后 , 我 得到 以下 错误 :
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'corsConfigurationSource' defined in class path resource [com/amrut/prabhu/oauth2/client/SecurityConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.cors.CorsConfigurationSource]: Factory method 'corsConfigurationSource' threw exception; nested exception is java.lang.NoClassDefFoundError: javax/servlet/ServletRequest

按热度按时间1wnzp6jl1#
在 React 式 应用 中 , 您 应该 构建
org.springframework.web.cors.reactive.CorsConfigurationSource
( 而 不是 用于 servlet 的org.springframework.web.cors.CorsConfigurationSource
) 。此外 , 在 构建 HTTP 安全 性 时 , 可能 需要 显 式 地 注入 bean :

# PS
你 可能 在 Baeldung 的 文章 中 找到 了 其他 方法 , 但 这 是 一 个 更 好 的 方法 :
# 完整 样品
我 刚刚 更新 了 this public repo 以 添加 网关 模块 。
Angular 应用 程序 位于
angular-workspace
文件 夹 中 。api
是 一 个 具有 两 个 资源 服务 器 的 Maven 多 模块 项目 :user-proxies-api
和greet-api
。 两者 都 使用 OAuth2 保护 。网关 简单 如 :
第 一 次
如果 您 需要 设置 Keycloak 和 配置 资源 服务 器 安全 性 的 详细 说明 , 请 参阅 those tutorials
