代碼生成器插件(mybatis-generator)代碼生成器插件

代碼生成器插件

代碼生成器插件(mybatis-generator)代碼生成器插件

1. 建立工程

建議：正式項目和代碼生成分别建立一個項目

複制了上次的javaEE工程規範化的最終工程

初始pom.xml

<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/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.teach</groupId>
    <artifactId>mybatis-generator</artifactId>
    <version>0.1</version>
    <packaging>war</packaging>
    
    <!-- 自定義配置資訊 -->
    <properties>
        <charset>UTF-8</charset>
        <jdk.version>1.8</jdk.version>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <argLine>-Dfile.encoding=UTF-8</argLine>
        <slf4j.version>1.7.25</slf4j.version>
    </properties>
​
    <dependencies>
        
    </dependencies>
    
    
    <build>
​
        <plugins>
            <!-- 工程編譯插件 -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.8.0</version>
                <configuration>
                    <source>${jdk.version}</source>
                    <target>${jdk.version}</target>
                    <encoding>${charset}</encoding>
                </configuration>
            </plugin>
​
        </plugins>
    </build>
​
</project>

2. 使用代碼生成插件

2.1. 添加插件依賴 

<!-- 插件運作指令：mybatis-generator:generate -X -->
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.6</version>
                <configuration>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>
                <dependencies>
                    <!-- 插件依賴的資料庫驅動 -->
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>5.1.28</version>
                    </dependency>
                </dependencies>
            </plugin>

2.2. 編寫插件配置檔案

檔案位置：src/main/resources/generatorConfig.xml

<?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>
    <context id="context1">
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <!-- 注釋開關 -->
            <property name="suppressAllComments" value="false"/>
        </commentGenerator>
​
        <jdbcConnection 
            connectionURL="jdbc:mysql://127.0.0.1:3306/user_product_news"
            driverClass="com.mysql.jdbc.Driver"
            password="" 
            userId="root" />
            
        <javaModelGenerator 
            targetPackage="com.teach.entity" 
            targetProject="src/main/java" />
            
        <sqlMapGenerator 
            targetPackage="com.teach.mapper"
            targetProject="src/main/resources" />
        <javaClientGenerator 
            targetPackage="com.teach.mapper"
            targetProject="src/main/java" 
            type="XMLMAPPER" />
​
        <!-- 下面添加需要自動生成MyBatis代碼的表 -->
        <!-- 
        <table schema="" tableName="news" domainObjectName="News" enableCountByExample="false" enableDeleteByExample="false" enableSelectByExample="false" enableUpdateByExample="false"/>
         -->
        <table schema="" tableName="%" enableCountByExample="false" enableDeleteByExample="false" enableSelectByExample="false" enableUpdateByExample="false"/>
    </context>
</generatorConfiguration>

3. 運作代碼生成器

mvn mybatis-generator:generate -X

4.上面是筆記，下面是我的配置檔案

generatorConfig.xml:

<?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>
	<context id="context1">
		<commentGenerator>
			<property name="suppressDate" value="flase" />
			<!-- 注釋開關 -->
			<property name="suppressAllComments" value="false" />
		</commentGenerator>
		<jdbcConnection
			connectionURL="jdbc:mysql://121.4.253.60:3306/bkpt?useUnicode=true&amp;characterEncoding=utf-8&amp;serverTimezone=GMT%2B8"
			driverClass="com.mysql.jdbc.Driver" 
			password="123456"
			userId="bkpt" />
		<javaModelGenerator 
			targetPackage="com.hx.entity"
			targetProject="src/main/java" />
		<sqlMapGenerator 
			targetPackage="com.hx.mapper"
			targetProject="src/main/resources" />
		<javaClientGenerator 
			targetPackage="com.hx.mapper"
			targetProject="src/main/java" 
			type="XMLMAPPER" />
		<!-- 下面添加需要自動生成MyBatis代碼的表 -->
		<!-- <table schema="" tableName="news" domainObjectName="News" enableCountByExample="false" 
			enableDeleteByExample="false" enableSelectByExample="false" enableUpdateByExample="false"/> -->
		<table schema="bkpt" tableName="%" enableCountByExample="false"
			enableDeleteByExample="false" enableSelectByExample="false"
			enableUpdateByExample="false" />
	</context>
</generatorConfiguration>
