I tried to use @Transactional
annotation in spring
and mybatis
using mybatis-spring
dependency. This is the service layer.
@Service
public class OracleService {
@Autowired
private TestMapper mapper;
@Autowired
private PlatformTransactionManager transactionManager;
@Transactional(propagation = Propagation.REQUIRED,
rollbackFor = Exception.class,
value = "transactionManager")
void insert1() {
TestModel testModel = new TestModel(1, "title1", "content1");
mapper.insert(testModel);
throw new RuntimeException();
}
}
As you can see, a RuntimeException
is thrown out in insert1()
, so the insert operation should fail. But in fact, it didn't. The record was inserted successfully. Why?
Here is my main method.
public class Launcher {
public static void main(String[] args) {
ApplicationContext cxt = new ClassPathXmlApplicationContext("spring-config.xml");
OracleService oracleService = cxt.getBean(OracleService.class);
try {
oracleService.insert1();
} catch(Exception e) {
System.out.println("Exception occurred!");
}
}
}
Spring configuration.

I used the following dependencies in pom.xml

<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.4.1</version>
</dependency>
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>

</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.3.2.RELEASE</version>
</dependency>
As @M.Deinum metioned, I have to make the method where @Transactional
applied public, in other words, I have to change
@Transactional(propagation = Propagation.REQUIRED)
void insert1() {
TestModel testModel = new TestModel(1, "title1", "content1");
mapper.insert(testModel);
throw new RuntimeException();
}
to
@Transactional(propagation = Propagation.REQUIRED)
public void insert1() {
TestModel testModel = new TestModel(1, "title1", "content1");
mapper.insert(testModel);
throw new RuntimeException();
}
The reason is written in the spring documentation.
Method visibility and @Transactional
When using proxies, you should apply the @Transactional annotation only to methods with public visibility. If you do annotate protected, private or package-visible methods with the @Transactional annotation, no error is raised, but the annotated method does not exhibit the configured transactional settings. Consider the use of AspectJ (see below) if you need to annotate non-public methods.
