Manifest merger failed : android: exported needs to be explicitly specified for. Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined.

<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />

Following the crud-ssm tutorial in Silicon Valley, insert the following bean tags when configuring the spring environment configuration file applicationcontext.xml,
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="configLocation" value="classpath:mybatis-config"></property>
<property name="dataSource" ref="dataSource"></property>
<property name="mapperLocations" value="classpath:mappers/*.xml"></property>
</bean>
among
<property name="mapperLocations" value="classpath:mappers/*.xml"></property>
It will be red. You only need to create any. XML file under Resources/maps, but this will lead to Title errors
just enter the project name\target\xxx-1.0-snapshot\WEB-INF\classes\mappers and delete the.XML file created at that time

There is an error in pushing from the local warehouse to the remote warehouse (rejected) because the code of the remote warehouse has been modified directly in the remote warehouse. At this time, the code of the local warehouse is different from that of the remote warehouse, so you must update the code of the local warehouse (Pull) first and then submit (push)
Error log in idea for this problem:

error log in Git bash:

at this time, you can only pull to update your local warehouse and then push to the remote warehouse, but you will find that you will also report an error when you pull to the local warehouse


at this time, your pull command should be changed to the following command, That is, just add a parameter to ignore the history (because the two branches are caused by different versions)
git pull origin master --allow-unrelated-histories
There is no other prompt for the error encountered when compiling orbslam3. ubuntu18.04
CMakeFiles/ORB_SLAM3.dir/build.make:110: recipe for target 'CMakeFiles/ORB_SLAM3.dir/src/LocalMapping.cc.o' failed
make[2]: *** [CMakeFiles/ORB_SLAM3.dir/src/LocalMapping.cc.o] Error 1
CMakeFiles/Makefile2:289: recipe for target 'CMakeFiles/ORB_SLAM3.dir/all' failed
make[1]: *** [CMakeFiles/ORB_SLAM3.dir/all] Error 2
Makefile:83: recipe for target 'all' failed
make: *** [all] Error 2
Solution:
Add the following code to the orb_SLAM3/include/CameraModels/KannalaBrandt8.h
namespace cv
{
template<typename _Tp, int m, int n> static inline Matx<_Tp, m, n> operator/(const Matx<_Tp, m, n>& a, float alpha)
{
return Matx<_Tp, m, n>(a, 1.f/alpha, Matx_ScaleOp());
}
}
As shown below

In addition, it is easy to get stuck during compilation. After making in build.sh, remove the multithreading options such as -J4-J
