在使用Maven工程管理工具整合SSM框架时，Mybatis使用逆向工程生成的pojo，mapper接口及映射文件，把mapper接口和映射文件放在DAO工程的同一级src/main/java目录下。正常启动服务器，浏览器执行业务Console控制台抛出异常：org.apache.ibatis.binding.BindingException: Invalid bound statement (not found)。

二、错误分析：
此异常的原因是由于mapper接口编译后在同一个目录下没有找到mapper映射文件而出现的。由于maven工程在默认情况下src/main/java目录下的mapper文件是不发布到target目录下的。
三、解决办法：
方法1：将Mapper映射文件放到src/main/resources目录下，然后再建一个和mapper接口所在的包名一样的包。
方法2：在此工程pom文件中配置一下resources。
1 <!-- 如果不添加此节点mybatis的mapper.xml文件都会被漏掉。 -->
2 <build>
3 <resources>
4 <resource>
5 <directory>src/main/java</directory>
6 <includes>
7 <include>**/*.properties</include>
8 <include>**/*.xml</include>
9 </includes>
10 <filtering>false</filtering>
11 </resource>
12 </resources>
13 </build>
四、注意事项：
原配置文件默认放在src/main/resources目录下，这样配置了之后，就指定src/main/java它是资源目录，src/main/resources目录就会不起作用了。如果不想这样，需要在配置中再加上一个resource节点，把src/main/resources目录也添加进来，即：
1 <!-- 如果不添加此节点mybatis的mapper.xml文件都会被漏掉。 -->
2 <build>
3 <resources>
4 <resource>
5 <directory>src/main/java</directory>
6 <includes>
7 <include>**/*.properties</include>
8 <include>**/*.xml</include>
9 </includes>
10 <filtering>false</filtering>
11 </resource>
12 <resource>
13 <directory>src/main/resources</directory>
14 <includes>
15 <include>**/*.properties</include>
16 <include>**/*.xml</include>
17 </includes>
18 <filtering>false</filtering>
19 </resource>
20 </resources>
21 </build>
