异常：

java.lang.IllegalArgumentException:?modify?is ambiguous in Mapped Statements collection (try using the full name including the namespace, or rename one of the entries)

抛出这个异常的原因可能是因为mapper.xml配置文件中<mapper>的namespace属性配置错误造成的，没有根据命名空间的值（全称类名）找到相应映射接口。

如：<mapper namespace="com.xxx.xxx.mapper.TestMapper" >
