解决方法：

在nutch2.1
中配置
<property>
? <name>encodingdetector.charset.min.confidence</name>
? <value>1</value>
? <description>A integer between 0-100 indicating minimum confidence value
? for charset auto-detection. Any negative value disables auto-detection.
? </description>
</property>
并确保mysql数据库编码为UTF-8
