tomcat升级，替换tomcat下的lib文件夹到最新版本的tomcat7.0.90，连接BI时报错 java.lang.IllegalArgumentException: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986 at org.apache.coyote.http11.InternalInputBuffer.parseRequestLine(InternalInputBuffer.java:194) at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1049) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:637) at org.apache.tomcat.util.net.JIoEndpoint$SocketProcessor.run(JIoEndpoint.java:318) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.lang.Thread.run(Thread.java:745) 解决办法：在tomcat/conf/server.xml中加入以下配置： relaxedQueryChars="|[]{}^" |
