java web开发入门十（idea创建maven SSM项目）基于intellig idea

一、搭建项目骨架

二、配置pom.xml

三、开发java和配置xml

.添加entity、dao、service、action、xml配置

省略

四、运行报错

原因是因为：maven项目默认不把java包下面的.xml文件编译输出，如下图：

 解决办法：打开pom.xml，在build节点下添加如下代码：

        <resources>
            <resource>
                <directory>src/main/javadirectory>
                <includes>
                    <include>**/*.xmlinclude>
                    <include>**/*.propertiesinclude>
                includes>
                <filtering>falsefiltering>
            resource>
