参考了这篇文章搭建了Mybaits环境，原作者有些地方没有标注使用某种编码，我是自学SQL的，所以深知编码格式的坑

1 create database mybatis;2 use mybatis;3 CREATE TABLE users(id INT PRIMARY KEY AUTO_INCREMENT, NAME VARCHAR(20), age INT);4 INSERT INTO users(NAME, age) VALUES(‘孤傲苍狼‘, 27);5 INSERT INTO users(NAME, age) VALUES(‘白虎神皇‘, 27);

这里建表的时候 最好指定编码格式为UTF8

CREATE TABLE users(id INT PRIMARY KEY AUTO_INCREMENT, NAME VARCHAR(20), age INT)engine = InnoDB default charset=utf8;//指定引擎为InnoDB 默认缺省编码为 utf8
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration>    <environments default="development">        <environment id="development">            <transactionManager type="JDBC" />            <!-- 配置数据库连接信息 -->            <dataSource type="POOLED">                <property name="driver" value="com.mysql.jdbc.Driver" />                <property name="url" value="jdbc:mysql://localhost:3306/mybaits?characterEncoding=utf8" />                <property name="username" value="root" />                <property name="password" value="admin" />            </dataSource>        </environment>    </environments>        <mappers>    <mapper resource="pw/jonwinters/mybaits/userMapper.xml"/></mappers> </configuration>
<property name="url" value="http://www.mamicode.com/jdbc:mysql://localhost:3306/mybaits?characterEncoding=utf8" />

这一行也改成utf8这样就不会出现编码错误了
