mybatis預設找的對映檔案路徑是src/main/resources，如果放在src/main/java下的一個包中，則需要在該專案的pom.xml檔案中加入：

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

此時找的就是src/main/java下的mapper所在的包中，要是還想繼續能找到
src/main/resources下的對映檔案，加個resource屬性：

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