idea社区版SmartTomcat启动web项目时出现

Could not resolve bean definition resource pattern [classpath:spring/applicationContext-*.xml]

后面接着的提示是

nested exception is java.io.FileNotFoundException: class path resource [spring/] cannot be resolved to URL because it does not exist

它的意思是不能解析bean的资源定义模式"spring/applicationContext-*.xml"

但是在工程里

以上两个文件都是存在的

maven在扫描java文件夹时，不会扫描其中的.xml文件，因为它默认是扫描java文件的，这样mapper.xml就会丢失而导致报错，所以我们会在pom文件中添加这样的配置：

<build> 
    <resources>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>false</filtering>
        </resource>
    </resources>
</build>

maven扫描src/main/java这个文件夹，并且要扫描所有.xml和.properties文件，这样一来可以解决maven扫描mapper.xml缺失的问题，但是由于修改了默认的resource目录，导致src/main/resources的所有文件都不能被扫描，也就出现了applicationContext文件不能被扫描的错误，所以应该配置两个

<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>

然后再重新加载和生成maven项目即可
