1、java工程，且是utf-8的编码；
2、mysql，utf-8编码；
3、插入中文，在数据库显示成??
4、如果加上useUnicode=true&characterEncoding=utf-8，则报如下错误
Caused by: com.mysql.jdbc.MysqlDataTruncation: Data truncation: Incorrect string value: '\xE5\x9B\xBD1\xE5\xAE...' for column 'name' at row 1。

eclipse也是UTF-8吗?

http://nutzbook.wendal.net/prepare/eclipse_utf8.html

eclipse也是UTF-8也是的。都不行

遇到utf8mb4问题了? 插入的ios那种表情符号

方案1：处理emoji表情，替换成图片

com.vdurmont
emoji-java
3.1.3

方案2：utf8mb4 （不推荐）

我其实就是个普通的增删改查，保存的就是一个name字段，内容就是"王大麻子"，但是到数据库是乱码

启动日志有打印mysql信息

另外，纯英文能不能插入

纯英文可以插入。
jdbc:mysql://127.0.0.1:3306/test，这样写也可以插入汉字，但是成了问号。

jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=UTF-8 这样写，就是上面报的错误了。

我的myeclipse,数据库，工程统统是UTF-8的

	public static void main(String[] args) {
		Ioc ioc = null; 
		try {
			ioc = new NutIoc(new JsonLoader("db.js"));
			DataSource ds = ioc.get(DataSource.class);
			Dao dao = new NutDao(ds);
			Person p = new Person();
			p.setName("中1国a");
			p.setAge(20);
			dao.insert(p);
		} finally { 
			ioc.depose();
		}

	}

{
    dataSource : {
        type : "com.alibaba.druid.pool.DruidDataSource",
        events : {
            depose : 'close'
        },
        fields : {
            driverClassName : "com.mysql.jdbc.Driver",

            password : "123456",
            maxWait: 15000, // 若不配置此项,如果数据库未启动,druid会一直等可用连接,卡住启动过程,
            defaultAutoCommit : false // 提高fastInsert的性能
        }
    }
}

乱码问题应该是比较简单的问题，但是用Nutz看起来不简单哈。

不要用test库

用别的数据库也不行哈

show create table 看看表的编码

CREATE TABLE t_person (
id bigint(20) unsigned NOT NULL AUTO_INCREMENT,
name varchar(20) NOT NULL,
age int(11) DEFAULT NULL,
PRIMARY KEY (id),
UNIQUE KEY name (name)
) ENGINE=InnoDB AUTO_INCREMENT=7 DEFAULT CHARSET=utf8

这其实，就是nutz入门里面的一个hello示例

难道是mariadb有什么特别的设置? 我下载同一个版本试试

安装的时候,没勾选 default charset as utf8 ?

绿色版的，我没用安装版的

区别是 character_set_server=utf8

我再关掉这个设置试试

我的为什么就不行呢
id name age
6 a?a1?a1 20
8 ??? 20

我如果加上 character_set_server=utf8就报错。
不加就乱码

各位，不报错了,还是得加上utf-8，我快放弃的时候，自动好了。我清理过了，应该不存在编译问题
jdbc:mysql://127.0.0.1:3306/nutz?useUnicode=true&characterEncoding=UTF-8

测试结果:

my.ini不加character_set_server=utf8, jdbcurl不加characterEncoding, 插入不报错, 数据库乱码

my.ini加character_set_server=utf8, jdbcurl不加characterEncoding, 插入不报错, 数据库正常

my.ini不加character_set_server=utf8, jdbcurl加characterEncoding, 插入不报错, 数据库正常

我至今没测出能抛异常的情况

PS: my.ini 改完均重启mysql服务

我的是加的。莫名问题，折腾快一天

[WinMySQLAdmin]
Server=D:\mariadb-10.1.19-winx64\bin\mysqld.exe
[mysqld]
basedir=D:\mariadb-10.1.19-winx64
datadir=D:\mariadb-10.1.19-winx64\data
default-character-set=utf-8
[client]
default-character-set=utf-8
port=3306

我猜抛错的原因是java源码是GBK编码的时候编译的, 然后项目改成UTF-8并没有触发编译.

my.ini的mysqld加了default-character-set=utf-8 且重启过, 日志里面肯定是character_set_server=utf8
