非常感谢各位
解决方案
如果您在Stackoverflow上搜索有关 的javax.persistence.EntityNotFoundException，您会发现问题出在您的IdRoles配置中。你这样定义它：
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private int idRoles;
@Id // should be removed
@Column(name = "IdRoles", nullable = false) // should be moved to field, int can't be null
public int getIdRoles() {
return idRoles;
}
您可以javax.persistence在字段或 getter 上放置注解，但不能同时在两者上。
请参阅：Hibernate Annoutations - 哪个更好，字段访问还是属性访问？
在您的情况下，有时持久层正在从 getter 读取属性，并且缺少@GeneratedValue()注释，因此等待您id为实体设置一个。
