如何启用CORS tomcat 8.5过滤器访问静态文件？

import javax.servlet.*;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class CORSFilter implements Filter {
    
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        // 初始化方法
    }
    
    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {
        
        HttpServletResponse httpResponse = (HttpServletResponse) response;
        
        // 添加CORS头
        httpResponse.addHeader("Access-Control-Allow-Origin", "*");
        httpResponse.addHeader("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE");
        httpResponse.addHeader("Access-Control-Allow-Headers", "Content-Type");
        
        chain.doFilter(request, response);
    }
    
    @Override
    public void destroy() {
        // 销毁方法
    }
}

<filter>
    <filter-name>CORSFilter</filter-name>
    <filter-class>com.example.CORSFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>CORSFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
