mybatis mapper xml: The content of element type "mapper" must match
提问by Verdagon
I'm having a hard time getting my simple mybatis file to work. I have this file:
我很难让我的简单 mybatis 文件工作。我有这个文件：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="truthtree.model.mysql.UserMapper">
<typeAlias alias="User" type="truthtree.model.mysql.User" />
<select id="getAllUsers" resultType="User">
select * from User
</select>
<select id="findUserByID" resultType="User">
select *
from User
where id=#{id,javaType=int}
</select>
<select id="findByNameAndPassword" resultType="User">
select *
from User
where name = #{name,javaType=String}
and password = #{password,javaType=String}
</select>
</mapper>
I get the following exception:
我收到以下异常：
Caused by: org.xml.sax.SAXParseException: The content of element type "mapper" must match "(cache-ref|cache|resultMap*|parameterMap*|sql*|insert*|update*|delete*|select*)+".
引起：org.xml.sax.SAXParseException：元素类型“mapper”的内容必须匹配“(cache-ref|cache|resultMap*|parameterMap*|sql*|insert*|update*|delete*|select*) +”。
Which is confusing because I definitely have some s in there. Any ideas what could be wrong here? Thanks!
这令人困惑，因为我肯定有一些 s 在那里。任何想法这里可能有什么问题？谢谢！

What you have wrong here is that the typeAliaselement does not go into the mapperfile. It's not present in the mybatis-3-mapper.dtd. The typeAliaselement has to be included in the mybatis-configfile (inside the typeAliaseselement, as it is clear in the mybatis-3-config.dtd:
你在这里的错误是该typeAlias元素没有进入mapper文件。它不存在于mybatis-3-mapper.dtd. 该typeAlias元素必须包含在mybatis-config文件中（在typeAliases元素内部，正如在mybatis-3-config.dtd:
<!ELEMENT typeAliases (typeAlias*,package*)>
<!ELEMENT typeAlias EMPTY>
<!ATTLIST typeAlias
type CDATA #REQUIRED
alias CDATA #IMPLIED
>
