    Caused by: org.hibernate.HibernateException: identifier of an instance of ... is alterde from

    Hibernate的提示错误

    org.hibernate.HibernateException: identifier of an instance of .[类名]. is alterde from [数字] to [数字]

    identifier of an instance of org.xx.xx was altered from 311097668476600320 to 311097668610818048; nested exception is org.hibernate.HibernateException: identifier of an instance of org.xx.xxx was altered from 311097668476600320 to 311097668610818048

    原因:

    先看错误代码:

    	/**
         * 新增用户权限
         * @param users
         * @param userRole
         * @return  执行结果
         * @throws Exception
         */
     public String insert(JSONArray userIds, JSONArray userRole)  throws Exception {
     		//将 JSONArray  转换实体类
            List<Role> userRoleList = (List<Role>) BaseUtils.toClassList(userRole, Role.class);
            String result = "";
            //循环要批量添加的用户权限
            for (int i = 0; i < userIds.size(); i++) {
                JSONObject jsonObject = userIds.getJSONObject(i);
                //循环转换后的用户 List
                for (Role role: userRoleList) {
                	//将userId赋值给权限
                    role.setRole_list(jsonObject.getString("userId"));
                    role.setId(IdWorker.getInstance().nextId());
                    //........判空之类的处理
                    result = BaseUtils.insert(role);
                }
            }
            return result;
        }
    

    错误提示:
    在这里插入图片描述
    原因是由于在一个事务中更新了主键,而主键是不能被更新的.

    解决方案:

    	/**
         * 新增用户权限
         * @param users
         * @param userRole
         * @return  执行结果
         * @throws Exception
         */
     public String insert(JSONArray userIds, JSONArray userRole)  throws Exception {
     		//将 JSONArray  转换实体类
            List<Role> userRoleList = (List<Role>) BaseUtils.toClassList(userRole, Role.class);
            String result = "";
            //循环要批量添加的用户权限
            for (int i = 0; i < userIds.size(); i++) {
                JSONObject jsonObject = userIds.getJSONObject(i);
                //循环转换后的用户 List
                for (Role role: userRoleList) {
    				/***************新增解决方法******************/
                	Role newRole = new Role();
                	//copy到新对象后进行 操作
                	BeanUtils.copyProperties(role, newRole);
    				/**********************************************/
                	//将userId赋值给权限
                    role.setRole_list(jsonObject.getString("userId"));

                    //........判空之类的处理
                    result = BaseUtils.insert(role);
                }
            }
            return result;
        }
