前言
最近要搞个发票保存的需求,当发票数据有id时说明是发票已经保存只需更新发票数据即可,没有id时说明没有发票数据需要新增发票;于是将原有的发票提交接口改造了下,将调用mybatis-plus的save方法改为saveOrUpdate方法,然后测试保存状态的发票提交时就报了一个很诡异的报错。。
部分代码
public class InvoiceServiceImpl extends ServiceImpl<InvoiceMapper, Invoice> implements InvoiceService {
@Override
@Transactional(rollbackFor = Exception.class)
public InvoiceDto saveInvoice(InvoiceDto invoiceDto, String scope) throws Exception {
//...省略其他代码
Invoice model = invoiceConverter.toModel(invoiceDto);
this.saveOrUpdate(model);
//...省略其他代码
}
}

怎么报了个没找到invoiceDto参数的错误呢,明明传了Invoice类型的参数进去,这时候点开看了下mybatis-plus的saveOrUpdate方法的逻辑如下
@Transactional(
rollbackFor = {Exception.class}
)
public boolean saveOrUpdate(T entity) {
if (null == entity) {
return false;
} else {
Class<?> cls = entity.getClass();
TableInfo tableInfo = TableInfoHelper.getTableInfo(cls);
Assert.notNull(tableInfo, "error: can not execute. because can not find cache of TableInfo for entity!", new Object[0]);
String keyProperty = tableInfo.getKeyProperty();
Assert.notEmpty(keyProperty, "error: can not execute. because can not find column for id from entity!", new Object[0]);
Object idVal = ReflectionKit.getMethodValue(cls, entity, tableInfo.getKeyProperty());
// 调用this.getById((Serializable)idVal))查看是否有值,有值的话调用updateById方法更新数据,否则调用save方法新增数据
return !StringUtils.checkValNull(idVal) && !Objects.isNull(this.getById((Serializable)idVal)) ? this.updateById(entity) : this.save(entity);
}
}
public T getById(Serializable id) {
return this.baseMapper.selectById(id);
}
public boolean updateById(T entity) {
return this.retBool(this.baseMapper.updateById(entity));
}
public boolean save(T entity) {
return this.retBool(this.baseMapper.insert(entity));
}
然后看到updateById方法的逻辑后,点了下baseMapper的updateById方法,因为装了插件,所以旁边有个小图标,点了下直接跳转到了自定义Mapper接口的updateById方法
好家伙,参数不对也调到了这个方法,然后因为我传的是Invoice类型的参数,而这个方法的接收参数第一个是InvoiceDto类型的参数,类型不匹配然后报错了
解决方法
将自定义mapper接口的这个updateById方法重新命名,不要和mybatis-plus的自带方法同名,我将它改成了updateInvoiceById这个名称就没报错了
