在maven+mybatis+spring集成开发时遇到错误，由于XML映射文件未被编译到输出路径，导致Bean创建失败。具体表现为Spring无法找到mapperLocations指定的资源。解决方案是在pom.xml的build部分增加配置，确保XML文件能被正确打包。

maven+mybatis+spring在开发的时候，遇到如下错误：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘xxxService’: Unsatisfied dependency expressed through field ‘xxxMapper’; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘xxxMapper’ defined in file [xxxMapper.class]: Cannot resolve reference to bean ‘sqlSessionFactory’ while setting bean property ‘sqlSessionFactory’; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘sqlSessionFactory’ defined in class path resource [xxx-mybatis.xml]: Initialization of bean failed; nested exception is org.springframework. beans.TypeMismatchException: Failed to convert property value of type ‘java.lang.String’ to required type ‘org.springframework.core.io.Resource[]’ for property ‘mapperLocations’; nested exception is java.lang.IllegalArgumentException: Could not resolve resource location pattern [classpath:com/xxx/xxx/mapping/*.xml]: class path resource [com/xxx/xxx/mapping/] cannot be resolved to URL because it does not exist

经过检查发现maven编译后并没有将xml文件打包到输出路径，导致bean创建失败。
因此解决方法就是在pom文件的build域中添加如下代码：

<build>
    ...
    <resources>
        <!--编译之后包含xml-->
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.xml</include>
            </includes>
            <filtering>true</filtering>
        </resource>
    </resources>
    ...
</build>
