CharacterEncodingFilter 未使用 spring-boot 1.2.0 和 spring-boot-legacy 设置

Question

我在 tomcat (servlet 2.5) 中运行传统的春季启动战。这些请求没有任何编码集，尽管 CharacterEncodingFilter 默认配置为 spring-boot 1.2.0。我可以看到它在自动配置和日志中配置。也许这不是由 spring-boot-legacy (1.0.1) 配置的？我将过滤器添加到 web.xml，我的请求现在具有 utf-8 编码。但是，这不适用于请求参数。我认为这是因为它不是访问请求的第一个过滤器（尽管它是我的 web.xml 中的第一个过滤器，它基于 spring-boot-legacy 示例）。在我失败的请求的堆栈跟踪中，我确实将 OncePerRequestFilter 视为第一个过滤器。有没有办法解决这个问题？

1. 使用DelegatingFilterProxy 进行字符编码（bean 名称为“characterEncodingFilter”）。
