mybatis中mapper绑定异常

在maven项目中，如果将mapper.xml文件放在了src/main/java下，会报mapper绑定异常

解决方法：在dao层的pom文件中添加如下配置

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

但是这样在src/main/resources下的资源就不会自动加载了，所以配置时可以将两个目录一起配置进去

  <!-- 如果不添加此节点mybatis的mapper.xml文件都会被漏掉。 -->
	<build>
		<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>
	</build>
