【java 9】-----Name不能添加中文？

 

前言：

       

    在编程好的系统中，输入数字、字母都没有问题，但是输入汉字，就读不出来出现“？”问号：

     

数据库表中的显示如下：

解决思路：

     

1,Eclipse/MyEclipse 软件改成utf-8:

       编辑工具中该项目，更改本项目的页面编码方式为utf-8

 

2,navicat 编码方式改成utf-8

       

3，数据库(mysql/oracle/sqlserver)的编码方式：

       改成国际统一编码方式utf-8，比如我自己用的是mysql数据库，更改方法如下，打开mysql控制台查看mysql编码当前表daniel 的编码方式“showcreate database daniel”；如果不是utf-8就进行更改，步骤是输入“alter database Daniel default character set utf8”在一次查看表daniel编码方式，步骤显示如下：

     

 

4，查看jdbc链接中有设置没有：

jdbcUrl      = jdbc:mysql://192.168.21.51:3306/itcastoa0720?characterEncoding=utf8driverClass  = com.mysql.jdbc.Driveruser         = rootpassword    = 1在数据库地址后面添加上“?characterEncoding=utf-8”jdbcUrl      = jdbc:mysql://192.168.21.51:3306/itcastoa0720?characterEncoding=utf8?characterEncoding=utf-8driverClass  = com.mysql.jdbc.Driveruser         = rootpassword    = 1

 

5，如果还是没有成功：

      单独的点击开你那字段的表，进行编辑改成utf-8:

   

 

结果：

   经过上面的一些更改，再一次输入中文字，哈哈，可以了！

     

 

总结：

       编码，听起来好简单，但是当时一直在查找解决方案，还问了曹学亮同学，农历好几个小时，感谢亮亮同我一起分析，进行思路的引导，最终还是一起分析出来了。

  

解决方案思路小结：

    1，Eclipse/myeclipse开发工具属性改成utf-8

    2,navicat 编码方式改成utf-8

    3，数据库（mysql/oracle/sqlservice）编码方式改成utf-8

    4，在项目jdbc文件中添加“?characterEncoding=utf-8”

   5，如果还是没成功，更改Navicat中单独字段为utf-8

一般是这几个地方更改成utf-8之后，成了国际统一编码，系统软件就乖乖的认了，想不显示汉字难了！
