tomcat 拦截特殊字符解决办法||||tomcat拦截特殊字符报400，如 “|“ “{“ “}“ “,“等符号的解决方案_tomcat8 汉字 400

错误概述及截图和400错误解析

传参数的时候又没有对“|”进行url编码这个时候他们用这个url访问我们会导致服务器一致报400的错误

解决办法

本地Tomcat的目录下有catalina.properties配置文件
修改其中的配置!~

放开这个注释即可,大致含义就是让浏览器解析"|" “{” “}” ","等特殊字符
Tomcat本地的catalina.properties建议和本人的Tomcat此项配置保持一直,配置如下(Tomcat已经用了四年工作第一年vlog)
