我已经通过在web.xml中使用error-page标记为任何http 5xx或4xx错误创建了自定义错误屏幕,但应该最好的方法是验证。我能够验证错误类型401和403,但不知道其他错误。

要快速手动测试以查看错误页面是否正常工作,我只需在处理请求的控制器代码中抛出运行时异常,例如:
throw new RuntimeException("test");

一个非常简单的servlet怎么样:
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@WebServlet(urlPatterns = "/testResponse")
public class TestResponseServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response ) throws ServletException, IOException {
String returnCode = request.getParameter("returnCode");
if( returnCode == null ) {
response.sendError(HttpServletResponse.SC_BAD_REQUEST, "missing returnCode parameter");
return;
}
response.sendError(Integer.parseInt(returnCode), "returned code " + returnCode );
}
}
用http://localhost:8080/testResponse?returnCode=505
