xml file problems and solutions in the engineering code does not compile the src directory of java

Maven project IDEA, the default source directory ( src/main/javathe directory) of xml files and other resources will not be packaged into a folder classes at compile time, but directly discard. If you are using Eclipse, xml and other Eclipse-src directory under the resource files automatically at compile time to classes packed into output folder.

Example:

When used in MyBatis IDEA, it would typically create a SQL mapping configuration file, if the file is in src / main / java directory, compiled in the target directory is not found in this document

For this issue of IDEA, the following solution:

The first method: If no special business, no need to specify resource files navigate to the src / main / java, you can create a main / resources directory under src, and place in which to require xml resource files. Tools maven default at compile time, the resource file folder resources will be packaged into a piece of classes directory.

For this use of MyBatis, we must specify the location mapper.xml file in the configuration file, for example, an increase in application.properties in springboot project:

mybatis.mapper-locations=classpath:mapper/*.xml

If an ordinary ssm project, then this configuration:

<bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="druidDataSource"/> <property name="configLocation" value="classpath:mybatis-config.xml"/> <!-- 配置mapper文件的位置 --> <property name="mapperLocations" value="classpath:mapper/*.xml"/> </bean>

The second method: the configuration file to configure the maven pom, find the <build> pom node file, add the following code:

 

<build>  
  <resources>  
    <!-- mapper.xml文件在java目录下 -->
    <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> </includes> </resource> <!-- mapper.xml文件在resources目录下--> <--<resource> <directory>src/main/resources</directory> </resource>--> </resources> </build>
