tomcat - 在 tomcat 中使用不同的适配器

Question

我想将 tomcat 7 配置为使用与默认 CoyoteAdapter 不同的适配器来处理一些格式错误的 cookie。这可能吗？

原因是我们低于异常

java.lang.IllegalArgumentException: Control character in cookie value or attribute.

Answer 1

您不能更改 coyote 适配器，除非您实现自己的 org.apache.coyote.Processor。但是在tomcat-8中，你可以改变cookie处理器:

1. 实现org.apache.tomcat.util.http.CookieProcessor
2. 将jar放到tomcat的lib文件夹中
3. 将 tomcat 配置为使用您自己的 cookie 处理器，方法是将其放入 context.xml 中:

<Context>
    <CookieProcessor className="org.example.MonsterCookieProcessor"/>
<Context>

遗憾的是，您不能在 tomcat-7 中这样做，因为 cookie 处理器逻辑被硬编码在 CoyoteRequest 中:

    private Cookies cookies = new Cookies(headers);
