IDEA Mybatis 找不到映射器xml文件
用IDEA新建了一个测试MyBatis工程,工程目录如下
其中config是MyBatis的配置文件,内容如下
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <environments default="development"> <environment id="development"> <transactionManager type="JDBC"></transactionManager> <dataSource type="POOLED"> <property name="driver" value="com.mysql.jdbc.Driver"/> <property name="url" value="jdbc:mysql://localhost:3306/mybatis"/> <property name="username" value="root"/> <property name="password" value="19871111"/> </dataSource> </environment> </environments> <mappers> <mapper resource="com/shao/mapping/userMapper.xml"/> </mappers> </configuration>
编译时提示错误 Error parsing SQL Mapper Configuration. Cause: java.io.IOException: Could not find resource com/shao/mapping/userMapper.xml
即找不到userMapper.xml这个Mapper文件,仔细查看了目录设置,并没有错误,在网上找了半天,终于发现原因:
idea不会编译src的java目录的xml文件
所以解决思路就是:将IDEA maven项目中src源代码下的xml等资源文件编译进classes文件夹
具体操作方法就是:配置maven的pom文件配置,在<build>节点下添加<resources>代码:
<build> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> </includes> </resource> </resources> </build>
