1 、将mybatis 的mapper.xm 文件放到 src 目录下,发现没有被编译到 class 文件
解决方式一:
(1)将mapper.xml 文件放到 resources 目录下
解决方式二:
(1)配置maven的pom文件配置,在pom文件中找到<build>节点,添加下列代码:
<build>
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.xml</include>
</includes>
</resource>
</resources>
</build>
<directory>src/main/java</directory>表明资源文件的路径,<include>**/*.xml</include>表明需要编译打包的文件类型是xml文件,如果有其它资源文件也需要打包,可以修改或添加通配符。
