Unsatisfied dependency:no identifier specified for entity 与 Could not determine type for

本文详细解析了在使用Hibernate框架时遇到的实体类主键配置及List类型映射问题,通过调整注解位置和实体类继承结构,成功解决了“noidentifierspecifiedforentity”及“Couldnotdeterminetypefor:java.util.List”等异常。

在使用hibernate的项目中就遇到了这个问题

一般先是:

Error creating bean with name 'xx': Unsatisfied dependency expressed through field 

然后最后指向

no identifier specified for entity xxx

百度一下,说是找不到 表实体  主键 配置问题:

可是 没有发现有问题啊。

最后对比了其他项目,发现是 继承的 实体父类,没有加上注解。 导致 实体父类的 主键属性识别不了

@MappedSuperclass 加上。

 

加上了之后 , 又 报错了

Caused by: org.hibernate.MappingException: Could not determine type for: java.util.List, at table: sys_group, for columns: [org.hibernate.mapping.Column(roles)]

 

原来是 实体类 一般在 属性 前面加上 表注解的,而不是get 方法上,而实体 类在get 上加了 注解。

不能混着用的。

@MappedSuperclass
public class BaseBIEntity implements Serializable {

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;

	@Id
	@GenericGenerator(name = "idGenerator", strategy = "uuid")
	@GeneratedValue(generator = "idGenerator")
	private String id; // ID
	
    //不能再 get方法上加上 注解,否则报错
	//@Id
	//@GenericGenerator(name = "idGenerator", strategy = "uuid")
	//@GeneratedValue(generator = "idGenerator")
	public String getId() {
		return id;
	}

	public void setId(String id) {
		this.id = id;
	}

}

This means that said other beans do not use the final version of the bean. This is often the result of over-eager type matching - consider using 'getBeanNamesForType' with the 'allowEagerInit' flag turned off, for example.
