Spring AOP with bean scanned using mybatis.spring.*.MapperScan - spring

Question

I am working on one component to achieve audit using Spring AOP. I could use it for most of the service's methods. But found that with Mybatis mappers AOP point-cuts don't work.
Basically, Spring AOP only works with Spring-managed beans. But these mapper beans have been scanned using mybatis.spring.*.MapperScan and can be autowired in other Spring components.
Why can these beans not be scanned for Spring AOP? Any idea?
I can use AspectJ but was keen to find out how mybatis.spring.*.MapperScan works.
for example -
I have these configurations one for Mybatis mapper scan and other config for application specific configurations.
#Configuration
#MapperScan("com.test.mapper")
public class ProviderConfiguration {
#Bean
public SqlSessionFactory sqlSessionFactory(final DataSource src) throws Exception {
...
}
}
#Configuration
#EnableAspectJAutoProxy
public class MainConfiguration {
}
My Dao logic where i call mapper method -
#Component
public class TestDao {
//injecting mybatis mapper here
#Inject
private SaveTableData saveTableData;
public TableData save(TableData tableData) {
saveTableData.updateTableData(tableData);
}
}
I have registered my pointcuts as below
#Component
#Aspect
public class TestAdvices {
#Pointcut("execution(* com.test.mapper.SaveTableData.updateTableData(*))")
public void commonSaveTableData(TableData tableData) {
}
#Pointcut("execution(* com.test.service.CreateTableData.createTableData(*))")
public void commonCreateTableData(TableData tableData) {
}
//advices
#After("commonSaveTableData(tableData)")
public void addHistoryWhenSaveTableData(TableData tableData) throws Throwable {
//do stuff
}
//advices
#After("commonCreateTableData(tableData)")
public void addHistoryWhenCreateTableData(TableData tableData) throws Throwable {
//do stuff
}
}
Issue is commonCreateTableData which is on service method works as expected. But commonSaveTableData which is on Mybatis mapper method does't get invoke.
Question is if i can autowire these Mappers in any Spring bean why can't Spring AOP intercept method call using these pointcuts?

Answer 1

I think your pointcut expression is not correct, try this
#Component
#Aspect
public class TestAdvices {
#Pointcut("execution(* com.test.mapper.SaveTableData.updateTableData(*)) && args(tableData)", argNames="tableData")
public void commonSaveTableData(TableData tableData) {
}
//advices
#After("commonSaveTableData(tableData)", argNames="tableData")
public void addHistoryWhenSaveTableData(TableData tableData) throws Throwable {
//do stuff
}
//...
}

The reason you can't cut into the mapper like this is that when mapper is scanned by mybatis, it's bean definition has bean changed in a way that its interface is still the mapper interface but its class has been changed to MapperFactoryBean
