Question

这是我的项目demo，我想使用MyBatis xml配置。但是我遇到了这样的SAXParseException错误

const localeCompare = Intl.Collator('en', { sensitivity: 'base' }).compare;
function includesByIgnoreCase(predicate) {
  if (this.filter(predicate).length > 0) {
    return true;
  }
  return false;
};

const value2 = ['hElLo', 'world', 'foo', 'Hello Wolrd'];

console.log(
  includesByIgnoreCase.call(
    value2,
    e => localeCompare(e, 'hello world') !== 0
  )
);

这是我的mapper xml文件：

问题在于您的mybatis配置：

mybatis:
  configuration:
    map-underscore-to-camel-case: true
  type-aliases-package: com.ryanqy.entity
  mapper-locations: mapper

将mapper-locations更改为：

  mapper-locations: mapper/UserMapper.xml
  #OR
  mapper-locations: mapper/*.xml

如果进行更改，则会在映射器XML中收到缺少DOCTYPE的错误，因此请添加类似的内容

<!DOCTYPE mapper
  PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

org.xml.sax.SAXParseException：序言中不允许内容
