如何用RestEasy在Java中实现服务器端的基本认证？我已经附加了我的过滤器，因为已经附加了Java Code.Sample代码

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

public class BasicAuthFilter implements Filter {
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        // 初始化操作
    }

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
        HttpServletRequest request = (HttpServletRequest) servletRequest;
        HttpServletResponse response = (HttpServletResponse) servletResponse;

        // 获取Authorization头部信息
        String authHeader = request.getHeader("Authorization");

        // 进行认证逻辑的处理，比如解析用户名和密码，验证用户信息等

        // 如果认证通过，继续处理请求
        filterChain.doFilter(request, response);
    }

    @Override
    public void destroy() {
        // 销毁操作
    }
}

<filter>
    <filter-name>BasicAuthFilter</filter-name>
    <filter-class>com.example.BasicAuthFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>BasicAuthFilter</filter-name>
    <url-pattern>/api/*</url-pattern>
</filter-mapping>

import javax.annotation.security.RolesAllowed;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Response;

@Path("/api")
public class MyResource {
    @GET
    @Path("/secured")
    @RolesAllowed("admin")
    public Response securedEndpoint() {
        // 认证通过的处理逻辑
        return Response.ok("Authenticated").build();
    }
}
