報錯以下:java

一直是不能建立bean的樣子,通過檢查發現mybatis的映射xml文件竟然沒有找到,發現classes目錄果真沒有*.xml,在pom文件中加入了以下代碼,問題成功解決。spring
<build> <resources> <!--編譯以後包含xml--> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> </includes> <filtering>true</filtering> </resource> </resources> </build>
