为什么第二个SQL是正常的，而第一个SQL显示错误：

Failed to encode '全国' in character set 'ISO-8859-1'

Answer 1

可以添加这样的代码：

System.setProperty("saffron.default.nationalcharset"，System.setProperty("saffron.default.charset"，ConversionUtil.NATIVE_UTF16_CHARSET_NAME)；System.setProperty ConversionUtil.NATIVE_UTF16_CHARSET_NAME + "$en_US")；

Answer 2

因为全国是未包含在ISO-8859-1中的字母。请确保使用UTF-8或UTF-16。
