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：

<!--默认不编译java包下面的.xml文件-->
        <resources>
            <resource>
                <directory>src/main/java</directory><!---设置编译的包-->
                <includes>
                    <include>**/*.xml</include><!--该路径下的.xml类型文件也要编译-->
                    <include>**/*.properties</include><!---该路径下的.properties类型文件也要编译-->
                </includes>
                <filtering>false</filtering>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
            </resource>
        </resources>
