Mybastic自動生成Mapper,Xml，Pojo。

使用mybatisGenerator插件可以自動生成Mapper,Xml，Pojo，減少工作量。

當然，也可以使用Mybastic Plus。

在Springboot項目中的src/main/resource目錄下加入mybatis-config.xml：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
	PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
	"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
	<!-- 全局的設置信息-->
	<settings>
		<!-- 配置用生成的主鍵值 -->
		<setting name="useGeneratedKeys" value="false"/>
		<!-- 啓用緩存 -->
		<setting name="cacheEnabled" value="true"/>
		<!-- 啓用延遲加載功能 -->
		<setting name="lazyLoadingEnabled" value="true"/>
		<!-- 按需要延遲加載-->
		<setting name="aggressiveLazyLoading" value="false"/>
		<!-- 開啓駝峯命名(方便自動映射)  -->
		<setting name="mapUnderscoreToCamelCase" value="true"/>
		<!-- 開啓SQL控制檯打印  -->
		<setting name="logImpl" value="SLF4J" />
	</settings>
	<!-- 批量設置別名(可以不配) 作用：就是在mapper.xml文件中直接寫類名，也可以不用寫全路徑名。 -->
	<typeAliases>
		<!--<package name="cn.e3mall.manager.po" />-->
	</typeAliases>

	<!-- 配置分頁插件 -->
	<plugins>
		<plugin interceptor="org.mybatis.extend.interceptor.PaginationInterceptor">
		</plugin>
	</plugins>
	
	
</configuration>

Springboot中使用mybastic，要在gradle的配置文件中 加入依賴。
implementation 'org.springframework.boot:spring-boot-starter'。

在gradle的配置文件中的configurations加入 mybatisGenerator 插件，

mybatisGenerator插件就是用來運行並生成生成Mapper,Xml，Pojo。

完整的配置文件settings.gradle如下：

buildscript {
    ext { springBootVersion = '2.2.6.RELEASE' }
    repositories {
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }

        //mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")

mybatisGenerator插件配置好後，就會在IDEA上顯示，點擊就運行。
