org.springframework.security.web.firewall.RequestRejectedException: The request was rejected because the URL contained a potentially malicious String "%2e"
org.springframework.security.web.firewall.RequestRejectedException: The request was rejected because the URL contained a potentially malicious String “%3B”
org.springframework.security.web.firewall.RequestRejectedException: The request was rejected because the URL contained a potentially malicious String “//”
类似这些报错，意思时请求URL中有非法字符“;”原因是SpringSecurity的防火墙中默认将分号，双斜线等特殊字符屏蔽掉了。
解决办法
-
1.去掉url中的分号，双斜线等特殊字符（推荐）
-
2.自定义防火墙规则，放行特殊字符
在SecurityConfig配置类中增加HttpFirewall的Bean
@Bean
public HttpFirewall allowUrlEncodedSlashHttpFirewall() {
StrictHttpFirewall firewall = new StrictHttpFirewall();
firewall.setAllowUrlEncodedDoubleSlash(true);
firewall.setAllowBackSlash(true);
firewall.setAllowSemicolon(true);
firewall.setAllowUrlEncodedPercent(true);
firewall.setAllowUrlEncodedSlash(true);
firewall.setAllowUrlEncodedPeriod(true);
return firewall;
}
同时在Websecurity中配置此bean
@Override
public void configure(WebSecurity web) throws Exception {
super.configure(web);
web.httpFirewall(allowUrlEncodedSlashHttpFirewall());
}
注：
setAllowSemicolon(true)为放行分号(;或者%3b或者%3B)，
setAllowUrlEncodedSlash(true) 放行斜杠(%2f或者%2F)
setAllowBackSlash(boolean) 放行反斜杠(\或者%5c或者%5B)
setAllowUrlEncodedPercent(boolean) 放行百分号(URL编码后为%25)
setAllowUrlEncodedPeriod(boolean) 放行英文句号.(%2e或者%2E)
