用postman输入中文参数调用，收到的都是乱码，必须手动把参数从iso8859-1转成utf-8

Answer 1

试下 修改servlet容器的编码设置 tomcat的话是server.xml，印象中

Answer 2

1.tomcat的server.xml配置

<Connector port="8080" protocol="HTTP/1.1"  
               connectionTimeout="20000"  
               redirectPort="8443"   
               URIEncoding="UTF-8"  
               useBodyEncodingForURI="true"  
               /> 

2.继承HttpServletRequestWrapper重写getParameter方法，在这个方法里面做字符串的编码转换
