由于未将
jar文件作为项目的一部分而出现该问题。我只是将其包含在tomcat lib中。
web.xml现在可以在工程中使用以下内容：
<filter> <filter-name>springSecurityFilterChain</filter-name> <filter-class> org.springframework.web.filter.DelegatingFilterProxy </filter-class></filter> <filter-mapping> <filter-name>springSecurityFilterChain</filter-name> <url-pattern>/*</url-pattern></filter-mapping><filter> <filter-name>CORS</filter-name> <filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class> <init-param> <param-name>cors.allowOrigin</param-name> <param-value>*</param-value> </init-param> <init-param> <param-name>cors.supportsCredentials</param-name> <param-value>false</param-value> </init-param> <init-param> <param-name>cors.supportedHeaders</param-name> <param-value>accept, authorization, origin</param-value> </init-param> <init-param> <param-name>cors.supportedMethods</param-name> <param-value>GET, POST, HEAD, OPTIONS</param-value> </init-param></filter><filter-mapping> <filter-name>CORS</filter-name> <url-pattern>/*</url-pattern></filter-mapping>
并且下面是您的项目依赖项：
<dependency> <groupId>com.thetransactioncompany</groupId> <artifactId>cors-filter</artifactId> <version>1.3.2</version></dependency>
