二、IDEA使用Tomcat服务器出现乱码问题

看到乱码，检查下面几个步骤看是否出了问题

#修改/etc/my.cnf或者/etc/mysql/my.cnf文件

[client]

default-character-set = utf8

[mysqld]

default-storage-engine = INNODB

character-set-server = utf8

collation-server = utf8_general_ci

#mysql 数据库连接使用utf-8

db.url=jdbc:mysql://localhost:3306/数据库名?characterEncoding=utf-8

#Tomcat—utf-8

#jsp — utf-8

<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8" %>

#web.xml—utf-8

        CharacterEncodingFilter

        org.springframework.web.filter.CharacterEncodingFilter

       

            encoding

            utf-8

       

   

   

        CharacterEncodingFilter

        /*

   

#request和response

request.setCharacterEncoding("utf-8");

response.setCharacterEncoding("utf-8");

response.setContentType("text/html;charset=utf-8");
