maven+mybatis+spring xml文件沒有編譯到輸出路徑

maven+mybatis+spring在開發的時候，遇到如下錯誤：

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

經過檢查發現maven編譯后并沒有將xml文件打包到輸出路徑，導致bean創建失敗。

因此解決方法就是在pom文件中添加如下代碼：

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