9.log4j.properties

配置日志文件 ，在resource目录下 创建 log4j.properties，文件内容如下：

#定义LOG输出级别 debug改成info信息输出变少
log4j.rootLogger=debug,Console,File
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以灵活地指定日志输出格式，下面一行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File = logs/ssm.log
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n
# sql语句显示
log4j.logger.com.ibatis=debug
log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=debug
log4j.logger.com.ibatis.common.jdbc.ScriptRunner=debug
log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=debug
log4j.logger.java.sql.Connection=debug
log4j.logger.java.sql.Statement=debug
log4j.logger.java.sql.PreparedStatement=debug
log4j.logger.java.sql.ResultSet=debug
log4j.logger.org.apache.ibatis.io=debug

10.一键生成mapper，dao，实体类

1.配置文件（方法一）

在 src/main/resources 创建xml文件generatorConfig.xml ，内容如下：(一键生成mapper，dao，实体类)

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE generatorConfiguration PUBLIC
        "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd" >
<generatorConfiguration> <!-- 配置驱动 -->
    <classPathEntry location="D:\.m2\repository\mysql\mysql-connector-java\5.1.30\mysql-connector-java-5.1.30.jar"/>
    <context id="context1">
        <commentGenerator> <!-- 不希望生成的注释中包含时间戳 -->
            <property name="suppressDate" value="true"/> <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/ssm"
                        userId="root" password="root"/> <!-- 生成实体类 实体bean文件 -->
        <javaModelGenerator targetPackage="com.hqyj.pojo" targetProject="src/main/java/"/> <!-- mapper xml文件 -->
        <sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources/"/> <!-- mapper 接口文件 -->
        <javaClientGenerator targetPackage="com.hqyj.dao" targetProject="src/main/java/"
                             type="XMLMAPPER"/> <!-- schema为数据库名，oracle需要配置，mysql不需要配置。 tableName为对应的数据库表名 domainObjectName 是要生成的实体类名(可以不指定) enableXXXByExample 默认为 true， 为 true 会生成一个对应Example帮助类，帮助你进 行条件查询，不想要可以设为false -->
        <table tableName="admin" domainObjectName="Admin" enableCountByExample="false" enableDeleteByExample="false"
               enableSelectByExample="false" enableUpdateByExample="false" selectByExampleQueryId="false"/>
    </context>
</generatorConfiguration>

2.图形化生产（方法二）
