Answer 1

你好，错误信息已经很明确了：
com.linkage.bss.commons.web.filter.CharsetEncodeFilter.doFilterInternal(CharsetEncodeFilter.java:41)
com.linkage.bss.commons.web.filter.OnceRequestFilter.doFilter(OnceRequestFilter.java:45)
就在这两句里面，参数类型不匹配，忘仔细检查。

Answer 2

把你这个文件代码com.linkage.bss.commons.web.filter.CharsetEncodeFilter发下
