MyBatis自定义插件:BaseResult添加映射

2016-09-02

BaseResult中添加映射

在文章DO模型添加变量中我们讲解了如何通过MyBaitsGenerate自定义插件为DO模型添加变量，然后根据SQL语句不同，我们还要在BaseResult中添加好相应的对应，才能从SQL的结果中获得正确的值

重写接口

能够获得BaseResult的接口是 sqlMapResultMapWithoutBLOBsElementGenerated

@Override
public boolean sqlMapResultMapWithoutBLOBsElementGenerated(XmlElement element, IntrospectedTable introspectedTable) {
    //Column Number
    XmlElement resultElement = new XmlElement("result");
    resultElement.addAttribute(new Attribute("column","column_count"));
    resultElement.addAttribute(new Attribute("property","columnCount"));
    resultElement.addAttribute(new Attribute("jdbcType","INTEGER"));
    element.addElement(resultElement);
    return super.sqlMapResultMapWithoutBLOBsElementGenerated(element, introspectedTable);
}

其中入参 element 就是resultMap节点，直接对其进行addElement添加一个result的Element即可
