最近搭建一个web项目后端SSM框架练手，使用Maven管理，遇到一个深坑invalid bound statement (not found)，就是mapper文件扫描不到！！！

先上整合过程，解决办法最后上。

1、项目结构：

2、pom文件：

导入的包有点多，可以根据自己需要选择导入。

只要路径都写正确，应该不会有什么问题吧？？？

BUT！！！

登录时竟然给我报了一个invalid bound statement (not found)的异常

网上都说这是路径不对或mapper文件内容不对引起的，但我路径都是对的，mapper文件时自动生成的，不会错啊，那到底是哪错了...

坑爹的问题害我找了一天原因，原来是需要在pom.xml文件中配置resource，不然mapper.xml文件就会被漏掉！被漏掉！！被漏掉！！！

然后就在pom.xml的<build>中配置了resource：

<!-- 如果不添加此节点mybatis的mapper.xml文件都会被漏掉。 -->
		<resources>
			<resource>
				<directory>src/main/java</directory>
				<includes>
					<include>**/*.properties</include>
					<include>**/*.xml</include>
				</includes>
				<filtering>false</filtering>
			</resource>
			<resource>
				<directory>src/main/resources</directory>
				<includes>
					<include>**/*.properties</include>
					<include>**/*.xml</include>
				</includes>
				<filtering>false</filtering>
			</resource>
		</resources>

上面pom.xml中已经把这段代码写上去了，这里只是说明一下错误时因为它引起的。

然后，哈哈哈，bug终于被我消灭，怪兽终究还是打不过葫芦娃的
