tomcat版本為Apache Tomcat/7.0.78
如下url用瀏覽器訪問時返回狀態(tài)400
http://192.168.34.1/Service.action?method=GetAddress¶m={}
而訪問這個正常
tomcat報錯信息如下

解決方法
參考這篇文章糠排，修改7.0.76以上tomcat配置就可以舵稠，可以不降級或者轉(zhuǎn)義
http://blog.csdn.net/aerchi/article/details/77963622
http://tomcat.apache.org/tomcat-8.0-doc/config/systemprops.html#Other
編輯conf/catalina.properties文件，將
tomcat.util.http.parser.HttpParser.requestTargetAllow注釋去掉入宦，并添加后面的字符
tomcat.util.http.parser.HttpParser.requestTargetAllow=| { }
