MyBatis 错误：KnowledgeBaseData 类缺少 'delete_flag' 属性的 Getter 方法

The error message suggests that there is no getter method for the property 'delete_flag' in the class 'com.hongkun.oss.domain.knowledgeBase.KnowledgeBaseData'. In order to fix this issue, you need to add the getter method for the 'delete_flag' property in the 'KnowledgeBaseData' class.

For example, if the 'delete_flag' property is of type Integer, you can add the following getter method in the 'KnowledgeBaseData' class:

public Integer getDeleteFlag() {
    return delete_flag;
}

Make sure to replace 'delete_flag' with the actual name of the property in your code.
