The content of element type "configuration" must match "(properties?,settings?,typeAliases?,typeHandlers?,objectFactory?,objectWrapperFactory?,reflectorFactory?,plugins?,environments?,databaseIdProv
在mybatis配置文件config.xml中报错:
The content of element type "configuration" must match
"(properties?,settings?,typeAliases?,typeHandlers?,objectFactory?,objectWrapperFactory?,reflectorFactory?,plugins?,environments?,databaseIdProvider?,mappers?)".
是因为配置信息的顺序放置错误,应遵循:
元素类型“配置”的内容必须匹配
“(属性?,设置?,typealiases?,typehandlers?、化?,objectwrapperfactory?,reflectorfactory?,插件吗?,环境?,databaseidprovider?,映射?)”。
示例代码
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://www.mybatis.org/dtd/mybatis-3-config.dtd"> <!--configuration根标签--> <configuration> <!-- 二、(1) 定义实体bean名和数据库列名相对应 type:实体的路径 alias:实体的别名 --> <typeAliases> <typeAlias type="com.ckx.entity.User" alias="User" /> </typeAliases> <!--二、 (2) 引入关系映射文件!!!这里有严格顺序!不能放在数据源配置前--> <mappers> <mapper resource="com.ckx.entityMapper.UserMapper.xml" /> </mappers> <!--一、 配置环境信息--> <environments default="admin"> <environment id="admin"> <!-- 指定事务管理机制--> <transactionManager type="JDBC"></transactionManager> <!-- 配置数据源 POOLED: 连接池--> <dataSource type="POOLED"> <property name="driver" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/ceshi?useUnicode=true&characterEncoding=utf8" /> <property name="username" value="root" /> <property name="password" value="123456" /> </dataSource> </environment> </environments> </configuration>
改变顺序即可消除错误:
