## 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：

报错日志如下：

## 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 ###

![Center 2][]

### 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：

![Center 3][]

### 4，查看jdbc链接中有设置没有： ###

jdbcUrl      = jdbc:mysql://192.168.21.51:3306/itcastoa0720?characterEncoding=utf8
    driverClass  = com.mysql.jdbc.Driver
    user         = root
    password    = 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-8
    driverClass  = com.mysql.jdbc.Driver
    user         = root
    password    = 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:

![Center 4][]

### 结果： ###

经过上面的一些更改，再一次输入中文字，哈哈，可以了！

![Center 5][]

## 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！
