Question

我每次试图与数据库连接时,都会保留这一例外。

Error building SqlSession.

The error may exist in SQL Mapper Configuration

Cause: org.apache.ibatis.builder.BuilderException: Error creating document instance. Cause: org.xml.sax.SAXParseException: The content of element type "dataSource" must match "(property)*".

我的Conifugration.xml档案:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <environments default="development">
        <environment id="development">
          <transactionManager type="JDBC"/>
          <dataSource type="POOLED">    
                <property name="driver" value="com.mysql.jdbc.Driver"/>
                <property name="url" value="jdbc:mysql://localhost:3360/teste"/>
                <property name="username" value="root"/>
                <property name="password" value="root"/>
           </dataSource>
        </environment>
    </environments>
</configuration>

我已经对此进行了搜索,研究了数据来源样本,就像其他样本一样。

谁知道什么?

Answer 1

我看一看MyBatis组合。我在文件结尾处有以下三行:</environments>和</configuration>。

<mappers>
  <mapper resource="YourHandbuiltOrMyBatisGeneratedMapper.xml"/>
</mappers>

地图仪是 Java接口,帮助 Java了解如何使用CRUD(Create, Read, Update, 删除)。这些信函的对应之处包括:斜体字插入()等接口;选择ByPrimaryKey, int UpdateByExample; int切除ByExample。

Hope that helps.

Answer 2

The exception is saying that the stuff inside your <dataSource/> element must be zero or one <property/> tags. Might you have inadvertently included a hidden character in your XML source file, perhaps from copying and pasting? Other than that I do not see anything wrong with your XML.
