java.lang.IllegalArgumentException: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986

今天使用AngularJS，從前台往后台傳值的時候，出現了這個異常：

java.lang.IllegalArgumentException: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986

org.apache.coyote.http11.AbstractHttp11Processor process
信息: Error parsing HTTP request header
Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.

這是因為，瀏覽器訪問的 URL中帶有特殊字符，比如：花括號、冒號，就會出現這個錯誤。
例如：http://localhost:8080/api/branch/save?{xxx:xxx}

而我當時就是這樣，我嘗試使用問號傳參的形式，將前端的對象轉換成JSON格式傳往后台，結果就出現了這個異常。

之后我換了種方式，不使用問號傳參，而是使用Rest風格的url，解決了此問題。
