Question

我在tomcat（servlet 2.5）中运行传统的spring boot war。请求没有任何编码集，尽管默认情况下使用spring-boot 1.2.0配置了CharacterEncodingFilter。我可以看到它在autoconfig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第一个访问请求的过滤器（尽管它是我的web.xml中的第一个过滤器，它基于spring-boot-legacy示例）。在我的失败请求的堆栈跟踪中，我确实看到OncePerRequestFilter作为第一个过滤器。有没有办法解决这个问题？

2条建议：

使用DelegatingFilterProxy进行字符编码（bean名称为＆＃34; characterEncodingFilter＆＃34;）。
您还必须在容器中设置URI编码以获取解码的请求参数（例如，在嵌入式容器中like this，但对于非嵌入式容器，它取决于您找到设置。）

CharacterEncodingFilter没有设置spring-boot 1.2.0和spring-boot-legacy
