maven 打包時mapper.xml打不進去問題

轉載：http://www.cnblogs.com/oyx305/p/5340683.html
一般情況下，我們用到的資源文件（各種xml，properites，xsd文件等）都放在src/main/resources下面，利用maven打包時，maven能把這些資源文件打包到相應的jar或者war裏。

有時候，比如mybatis的mapper.xml文件，我們習慣把它和Mapper.java放一起，都在src/main/java下面，這樣利用maven打包時，就需要修改pom.xml文件，來把mapper.xml文件一起打包進jar或者war裏了，否則，這些文件不會被打包的。（maven認爲src/main/java只是java的源代碼路徑）。網絡上有很多方法，我大概試了下，幾種方法都可以，可以任選一種即可。
