问题:Tomcat抛出异常,导致400 –错误请求。

从7.0.88开始,大多数tomcat版本都会出现此问题。

解决方案:(由Apache团队建议):

Tomcat增强了其安全性,并且不再允许在查询字符串中使用原始方括号。在请求中,我们有{,} 或其他符号,因此服务器未处理该请求。

在tomcat conf路径下的server.xml文件里面的 Connector 标签下添加属性 relaxedQueryChars:

<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443"
maxHttpHeaderSize ="10240"
relaxedQueryChars="{,}"/>

如果应用程序需要默认情况下tomcat不支持的更多特殊字符,请在relaxedQueryChars上述属性中添加这些特殊字符,并以逗号分隔。
