java - 使用 Spring MVC 为所有 API 启用 CORS

Question

如何“轻松”配置 Spring MVC，以便对应用程序中任何 API 的每个请求都返回神奇的 CORS header ？

例如，使用 @ControllerAdvice 或使用常见的 AOP 建议。

Answer 1

我通过以下步骤解决:

1. 添加 Maven 依赖

<dependency>
  <groupId>com.thetransactioncompany</groupId>
  <artifactId>cors-filter</artifactId>
  <version>2.2.1</version>
</dependency>

1. 在 web.xml 中添加此参数

   <filter>
   <filter-name>CORS</filter-name>
   <filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>
   
   <init-param>
       <param-name>cors.allowGenericHttpRequests</param-name>
       <param-value>true</param-value>
   </init-param>
   
   <init-param>
       <param-name>cors.allowOrigin</param-name>
       <param-value>*</param-value>
   </init-param>
   
   <init-param>
       <param-name>cors.allowSubdomains</param-name>
       <param-value>false</param-value>
   </init-param>
   
   <init-param>
       <param-name>cors.supportedMethods</param-name>
       <param-value>GET, HEAD, POST, DELETE, OPTIONS</param-value>
   </init-param>
   
   <init-param>
       <param-name>cors.supportedHeaders</param-name>
       <param-value>*</param-value>
   </init-param>
   
   <init-param>
       <param-name>cors.supportsCredentials</param-name>
       <param-value>true</param-value>
   </init-param>
   
   <init-param>
       <param-name>cors.maxAge</param-name>
       <param-value>3600</param-value>
   </init-param>   
   </filter>
