idea开发mavenweb项⽬时，target⽬录中的dao中没有xml⽂
件
在开发maven web项⽬时，因为是ssm项⽬，所以在dao层⾥有xml⽂件，以前也是这么开发的，但今天就出现了⼀下的错误

⼀开始看到这个错以为⾃⼰的把配置⽂件写错了，也就是什么名称写错了，可是从头检查⼀遍发现没有任何问题，这就很难受了，因为定位不到错误，所以这就是最尴尬的结果，最后仔细看过出现这个错误的所有原因发现，target中的dao层⾥的xml⽂件不见了，那么问题了，离解决它也就不远了，所以下⾯就是解决⽅案了
对于MAVEN项⽬，Eclipse会⾃动把项⽬src\main\java\⽬录下的配置⽂件（.xml）和资源⽂件(.properties)搬运到target⽬录下，⽽intellij idea默认是不会帮我们做这件事的。
<build>
<finalName>SSMDemo5</finalName>
<!--解决Intellij构建项⽬时，target/classes⽬录下不存在l⽂件-->
<resources>
<resource>
<directory>${basedir}/src/main/java</directory>
<includes>
<include>**/*.xml</include>
</includes>
</resource>
</resources>
</build>
在pom⽂件⾥把上⾯这段代码添加进去就好了，这段代码的意思就是把src/main/java⽬录下所有的xml
⽂件都包含进去，其中${basedir}是MAVEN的内置变量，表⽰项⽬根⽬录。同样，想包含其他什么⽂件，⽐如.properties⽂件，再加⼀个<include>标签类似的写法即可。
