錯誤資訊：

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.qin.mybatis.mapper.UserMapper.insertUser
	at org.apache.ibatis.binding.MapperMethod$SqlCommand.<init>(MapperMethod.java:223)
	at org.apache.ibatis.binding.MapperMethod.<init>(MapperMethod.java:48)
	at org.apache.ibatis.binding.MapperProxy.cachedMapperMethod(MapperProxy.java:59)
	at org.apache.ibatis.binding.MapperProxy.invoke(MapperProxy.java:52)
	at com.sun.proxy.$Proxy2.insertUser(Unknown Source)
	at com.qin.mybatis.controller.UserController.main(UserController.java:37)
 

可能的原因：

1、Mapper介面和xml檔案的名稱對應不上，需要檢查包名，namespace，函式名稱等能否對應上。 

2、如果以上沒有錯誤，可能是編譯的問題，在pom.xml檔案中新增如下資訊：

<build>
	<resources>
		<resource>
			<directory>src/main/java</directory>
			<includes>
				<include>**/*.xml</include>
			</includes>
		</resource>
	</resources>
</build>
