通用 Mapper4 是一個可以實現任意 MyBatis 通用方法的框架，項目提供了常規的增刪改查操作以及Example 相關的單表操作。通用 Mapper 是爲了解決 MyBatis 使用中 90% 的基本操作，使用它可以很方便的進行開發，可以節省開發人員大量的時間。
環境及版本信息：
開發IDE軟件：idea
spring boot 2.1.1.RELEASE
mysql 驅動 5
tk.mybatis 4.0.0
採用原文中的第二種方式 使用maven插件形式運行MBG
- 使用spring boot初始化整個項目
pom.xml 該文件可用於生成代碼和spring boot項目使用<?xml version="1.0" encoding="UTF-8"?> <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> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.1.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.zjchsoft.bi</groupId> <artifactId>tkmb</artifactId> <version>1.0.0-SNAPSHOT</version> <name>tkmb</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid-spring-boot-starter</artifactId> <version>1.1.10</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.25</version> </dependency> <!-- 通用 Mapper --> <!-- https://mvnrepository.com/artifact/tk.mybatis/mapper --> <dependency> <groupId>tk.mybatis</groupId> <artifactId>mapper</artifactId> <version>4.0.0</version> </dependency> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper</artifactId> <version>4.2.1</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.29</version> </dependency> <!-- https://mvnrepository.com/artifact/tk.mybatis/mapper-spring-boot-starter --> <dependency> <groupId>tk.mybatis</groupId> <artifactId>mapper-spring-boot-starter</artifactId> <version>2.1.2</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.2</version> <configuration> <configurationFile>${basedir}/src/main/resources/generator/generatorConfig.xml</configurationFile> <overwrite>true</overwrite> <verbose>true</verbose> </configuration> <dependencies> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.29</version> </dependency> <dependency> <groupId>tk.mybatis</groupId> <artifactId>mapper</artifactId> <version>4.0.0</version> </dependency> </dependencies> </plugin> </plugins> </build> </project> - plug引入（此處使用了MySQL驅動及配置文件）
