我收到org.springframework.orm.hibernate4.HibernateSystemException：非法尝试在更新实体时将代理与两个打开的Sessions Exception关联。我尝试了很多方法来配置我的事务管理器，但仍然是相同的。没有得到我错误的地方...... :(
Category.java
@Entity
@Table(name = "oc_category")
public class Category implements java.io.Serializable {
private Long categoryId;
private String image = "web-resources/image/no_image-45x45.png";
private Integer parentId = 0;
private Integer column = 1;
private Integer sortOrder = 0;
private Boolean status = false;
private Date dateAdded;
private Date dateModified;
private CategoryDescription categoryDescription;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "category_id", unique = true, nullable = false)
public Long getCategoryId() {
return categoryId;
}
.
.
.
@OneToOne(cascade=CascadeType.ALL)
@JoinColumn(name = "category_desc_id")
public CategoryDescription getCategoryDescription() {
return categoryDescription;
}
.
CategoryDescription.java
@Entity
@Table(name = "oc_category_description")
public class CategoryDescription implements java.io.Serializable {
private Long categoryDescId;
private String name;
private String description;
private String metaTitle;
private String metaDescription;
private String metaKeyword;
private Language language;
private Store store;
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name = "category_desc_id", unique = true, nullable = false)
public Long getCategoryDescId() {
return categoryDescId;
}
来自Controller我从save方法调用 categoryService.save（category）;
我的服务impl类是
@Service
public class CategoryServiceImpl implements CategoryService {
@Autowired
@Resource(name="categoryDAO")
private CategoryDAO categoryDAO;
public void setCategoryDAO(CategoryDAO categoryDAO) {
this.categoryDAO = categoryDAO;
}
@Transactional
public void save(Category entity) {
categoryDAO.save(entity);
}
}
Dao impl是
@Repository(value = "categoryDAO")
public class CategoryDAOImpl implements CategoryDAO{
@Autowired
SessionFactory sessionFactory;
@Override
public void save(Category entity) {
try {
sessionFactory.getCurrentSession().saveOrUpdate(entity);
} catch (Exception exception)
{
exception.printStackTrace();
}
}
}
最后配置文件是
<tx:annotation-driven />
<context:component-scan base-package="com" />
<context:property-placeholder location="classpath:database.properties" />
<mvc:annotation-driven />
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">

保存新类别，CategoryDescription工作正常，同时点击编辑并再次保存，获取 org.springframework.web.util.NestedServletException：请求处理失败;嵌套异常是org.springframework.orm.hibernate4.HibernateSystemException：非法尝试将代理与两个打开的Sessions关联;嵌套异常是org.hibernate.HibernateException：非法尝试将代理与两个打开的会话相关联
从哪里开始2场会议，请帮忙
