Mybaits-Maven项目之逆向工程（代码自动生成）

1、添加maven插件，让maven环境支持mybatis-generator组件
在pom.xml里面添加如下代码：

<project xmlns="http://maven.apache.org/POM/4.0.0"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
	<modelVersion>4.0.0</modelVersion>
	<groupId>20180611</groupId>
	<artifactId>ddd</artifactId>
	<packaging>war</packaging>
	<version>0.0.1-SNAPSHOT</version>
	<name>ddd Maven Webapp</name>
	<url>http://maven.apache.org</url>
	<dependencies>
		<dependency>
			<groupId>junit</groupId>
			<artifactId>junit</artifactId>
			<version>3.8.1</version>
			<scope>test</scope>
		</dependency>
	</dependencies>
	<build>
		<finalName>taotao</finalName>
		<pluginManagement>
			<plugins>
				<plugin>
					<groupId>org.mybatis.generator</groupId>
					<artifactId>mybatis-generator-maven-plugin</artifactId>
					<version>1.3.2</version>
					<configuration>
						<configurationFile>src/main/resources/generator.xml</configurationFile>
						<verbose>true</verbose>
						<overwrite>true</overwrite>
					</configuration>
					<executions>
						<execution>
							<id>Generate MyBatis Artifacts</id>
							<goals>
								<goal>generate</goal>
							</goals>
						</execution>
					</executions>
					<dependencies>
						<dependency>
							<groupId>org.mybatis.generator</groupId>
							<artifactId>mybatis-generator-core</artifactId>
							<version>1.3.2</version>
						</dependency>
						<dependency>
							<groupId>mysql</groupId>
							<artifactId>mysql-connector-java</artifactId>
							<version>5.1.35</version>
							<scope>runtime</scope>
						</dependency>

					</dependencies>
				</plugin>
				<plugin>
					<groupId>org.apache.maven.plugins</groupId>
					<artifactId>maven-surefire-plugin</artifactId>
					<version>2.19.1</version>
					<configuration>
						<skipTests>true</skipTests>
					</configuration>
				</plugin>

				<plugin>
					<groupId>org.apache.maven.plugins</groupId>
					<artifactId>maven-resources-plugin</artifactId>
					<version>3.0.1</version>
					<configuration>
						<encoding>UTF-8</encoding>
					</configuration>
				</plugin>
				
				<!--JDK版本 -->
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-compiler-plugin</artifactId>
				<version>2.5.1</version>
				<configuration>
					<source>1.8</source>
					<target>1.8</target>
					<encoding>UTF-8</encoding>
					<showWarnings>true</showWarnings>
				</configuration>
			</plugin>
			</plugins>
		</pluginManagement>
	</build>

</project>

　　

2、新建generator.xml配置文件

注意：其中的数据可驱动包位置需要手动指向本机的绝对地址：我的本机地址是：G:\mysql-connector-java-5.1.37-bin.jar

<?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>
	<!-- 数据库驱动包位置 -->
	<classPathEntry
		location="G:\mysql-connector-java-5.1.37-bin.jar" />
	<context id="Tables" targetRuntime="MyBatis3">
		<commentGenerator>
			<!-- 是否去除自动生成的注释 true：是 ： false:否 -->
			<property name="suppressAllComments" value="true" />
		</commentGenerator>
		<!-- 数据库链接URL、用户名、密码 -->
		<jdbcConnection driverClass="com.mysql.jdbc.Driver"
			connectionURL="jdbc:mysql://39.108.217.125:3306/RoboBlogs"
			userId="root" password="HZBhzb1237763522-1">
			<!--<jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver" connectionURL="jdbc:oracle:thin:@localhost:1521:orcl" 
				userId="msa" password="msa"> -->
		</jdbcConnection>
		<javaTypeResolver>
			<!-- 默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer， 为 true时把JDBC DECIMAL和NUMERIC类型解析为java.math.BigDecimal -->
			<property name="forceBigDecimals" value="true" />
		</javaTypeResolver>
		<!-- 生成实体类的包名和位置，这里配置将生成的实体类放在com.loan.test.entity这个包下 -->
		<javaModelGenerator
			targetPackage="com.Mybaits.pojo" targetProject=".\src\main\java\">
			<!-- enableSubPackages:是否让schema作为包的后缀 -->
			<property name="enableSubPackages" value="true" />
			<!-- 从数据库返回的值被清理前后的空格 -->
			<property name="trimStrings" value="true" />
		</javaModelGenerator>
		<!-- 生成的SQL映射文件包名和位置，这里配置将生成的SQL映射文件放在com.loan.test.dao.xml这个包下 -->
		<sqlMapGenerator targetPackage="com.Mybaits.dao.xml"
			targetProject=".\src\main\java\">
			<!-- enableSubPackages:是否让schema作为包的后缀 -->
			<property name="enableSubPackages" value="true" />
		</sqlMapGenerator>
		<!-- 生成DAO的包名和位置，这里配置将生成的dao接口放在com.loan.test.dao.mapper这个包下 -->
		<javaClientGenerator type="XMLMAPPER"
			targetPackage="com.Mybaits.dao.mapper"
			targetProject=".\src\main\java\">
			<!-- enableSubPackages:是否让schema作为包的后缀 -->
			<property name="enableSubPackages" value="true" />
		</javaClientGenerator>
		<!-- 要生成那些表(更改tableName和domainObjectName就可以) -->
		<table tableName="u01" domainObjectName="u01"
			enableCountByExample="false" enableUpdateByExample="false"
			enableDeleteByExample="false" enableSelectByExample="false"
			selectByExampleQueryId="false" />
		<table tableName="Upload_info" domainObjectName="Upload_info"
			enableCountByExample="false" enableUpdateByExample="false"
			enableDeleteByExample="false" enableSelectByExample="false"
			selectByExampleQueryId="false" />
		<table tableName="Upload_UserPushContent" domainObjectName="Upload_UserPushContent"
			enableCountByExample="false" enableUpdateByExample="false"
			enableDeleteByExample="false" enableSelectByExample="false"
			selectByExampleQueryId="false" />
	</context>
</generatorConfiguration>

　　3、运用maven指令生成逆向工程

             项目右键->run as->maven build...,Goals:中输入mybatis-generator:generat，如图：

   4、刷新项目。
