Create Project: Omit

Structure diagram:

I mainly explain the places that need to be paid attention to + mybatis is automatically generated

① Because it is multi-module; our configuration file is placed in shuang-project-web-backend

If you scan the configuration of mapper.xml

<property name="mapperLocations" value="classpath:com/mote/mapper/*.xml"></property>

may not be found;

Solution one:

classpath*：

Difference between classpath and classpath*

The difference between classpath and classpath*:
classpath: will only look for files in your classpath;

classpath*: includes not only the class path, but also the jar file (class path) for searching.

After the above modification, the .xml file cannot be scanned;

Found out:

The .xml file must be placed under the resource folder; otherwise, the code in the above figure must be added to find it;

 <!-- The following paragraph must be added because files other than resources cannot be scanned when scanning xml files in the field , unless you specify -->
 <!-- <build>
      <resources>
          <resource>
              <directory>src/ main/java</directory>
          </resource>
      </resources>
 </build>-->

Problem 2: The transaction does not take effect

Reason: When scanning the Controller, the services layer is also scanned; remove the Services or only scan the Controller

<!-- 把标记了@Controller注解的类转换为bean -->
<!-- 下面一点要将services 注解的规避掉；不能扫描services 否则事务不生效-->
<context:component-scan base-package="com.mote">
   <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/>
</context:component-scan>

问题三：.NoClassDefFoundError: org/springframework/ui/freemarker/FreeMarkerConfigurationFactory

缺少jar

< dependency >
< groupId >org.springframework </ groupId >
< artifactId >spring-context-support </ artifactId >
< version >4.1.6.RELEASE </ version >
</ dependency >

自动生成

看项目里面的配置
