How to use @Transactional annotation in mybatis-spring?

Question

I tried to use @Transactional annotation in spring and mybatis using mybatis-spring dependency. This is the service layer.

Answer 1

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.
