         version="4.0"
         metadata-complete="true">

</web-app>

2、maven资源导出失败的问题

<!--在build中配置resources，防止资源导出失败的问题-->
<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>true</filtering>
        </resource>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>true</filtering>
        </resource>
    </resources>
</build>

3.1、

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-////DTD Config 3.0//EN"
        "/dtd/">
<configuration>
    
    <properties resource=""/>
    
    <settings>
        <setting name="logImpl" value="STDOUT_LOGGING"/>
    </settings>

    <typeAliases>
        <package name=""/>
    </typeAliases>

    <environments default="development">
        <environment id="development">
            <transactionManager type="JDBC"/>
            <dataSource type="POOLED">
                <property name="driver" value="${driver}"/>
                <property name="url" value="${url}"/>
                <property name="username" value="${username}"/>

    </mappers>
</configuration>

3.2、(数据库配置文件)

password=123456

3.3、

<?xml version="1.0" encoding="UTF-8" ?>

        PUBLIC "-////DTD Mapper 3.0//EN"
        "/dtd/">
<mapper namespace="">

</mapper>

3.4、

#将等级为DEBUG的日志信息输出到console和file这两个目的地，console和file的定义在下面的代码
=DEBUG,console,file

#控制台输出的相关设置
 = .
 = 
=DEBUG
 = .
=[%c]-%m%n

#文件输出的相关设置
 = .
=./log/
=10mb
=DEBUG
=.
=[%p][%d{yy-MM-dd}][%c]%m%n

#日志输出级别
=DEBUG
=DEBUG
=DEBUG
=DEBUG
=DEBUG

3.5、

import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import java.io.IOException;
import java.io.InputStream;

public class MyBatisUtils {

    private static SqlSessionFactory sqlSessionFactory;

    static {
        try {
            String resources="";
            InputStream inputStream = Resources.getResourceAsStream(resources);
            sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public static SqlSession getSqlSession(){
        //true：自动提交事务,默认为false
        return sqlSessionFactory.openSession(true);
    }
}

4、

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="/schema/beans"
       xmlns:xsi="http:///2001/XMLSchema-instance"
       xsi:schemaLocation="/schema/beans
