Spring JPA Junit 关闭自动回滚

使用JPA配合Hibernate ，采用注解默认是开启了LayzLoad也就是懒加载，所以不得不在Junit的单元测试上加上@Transactional注解，这样Spring会自动为当前线程开启Session,这样在单元测试里面懒加载才不会因为访问完Repository之后，出现session not found.
但是单元测试里面如果加上了@Transactional 会自动回滚事务，需要在单元测试上面加上@Rollback(false)，这样才能插入数据库

    @Test
    @Transactional
    @Rollback(false) //关闭自动回滚
    public void saveTest() {
        ProductCategory category = new ProductCategory();
        category.setCategoryname("快乐");
        category.setCategorytype(6);
        ProductCategory save = categoryRepository.save(category);
        System.out.println(save.toString());
    }

控制台打印的日志，显示提交事务

Hibernate: insert into product_category (category_name, category_type) values (?, ?)
ProductCategory{categoryid=8, categoryname='快乐', categorytype=6}
