Question

我是Spring的新手，使用版本3.2和Hibernate 4.1.9Final，似乎@Transactional注释被忽略了，我试图在控制器方法，服务方法和dao上设置它，没有成功

我已将这些软件包包含在

中

的web.xml

我的测试控制器

public class HelloController {

    @Autowired
    private CategoryService categories;

    public HelloController() {
        System.out.println("test!!!");
    }

    public void setCategoryService(CategoryService categories) {
        this.categories = categories;
    }

    @RequestMapping(value = "/", method = RequestMethod.GET)
    @Transactional
    public String getIndex() {
        Category c = new Category();
        c.setName("Test");
        categories.save(c);
        return "index";
    }
}

堆栈跟踪：

Answer 1

删除了hibernate.current_session_context_class = thread并且它可以正常工作。 Spring在使用Spring事务支持层时注入自己的会话上下文管理实现？

Answer 2

您在控制器层中使用@Transactional。它应该在您的服务层中。

制作Categories.save方法@Transactional，您可能会收到此错误。

Answer 3

尝试添加<context:component-scan base-package="your package here">

看起来它无法找到注释

Spring 3.2 Hibernate没有活动事务
