spring boot 自动生成数据库对应的实体类和mapping文件

1、数据库创建好表。

2、srcmain esourcesmybatismybatis-generator.xml  创建mybatis-generator.xml 文件，内容如下：

<?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>

    <!-- 本地数据库驱动程序jar包的全路径 -->
 <classPathEntry location="D:
epomysqlmysql-connector-java8.0.21"/>

    <context />
    </context>
</generatorConfiguration>
3、配置pom文件：

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>1.3.5</version>
            <dependencies>
                <dependency>
                    <groupId> mysql</groupId>
                    <artifactId> mysql-connector-java</artifactId>
                    <version> 8.0.21</version>
                </dependency>
                <dependency>
                    <groupId>org.mybatis.generator</groupId>
                    <artifactId>mybatis-generator-core</artifactId>
                    <version>1.3.5</version>
                </dependency>
            </dependencies>
            <executions>
                <execution>
                    <id>Generate MyBatis Artifacts</id>
                    <phase>package</phase>
                    <goals>
                        <goal>generate</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <!--允许移动生成的文件 -->
                <verbose>true</verbose>
                <!-- 是否覆盖 -->
                <overwrite>true</overwrite>
                <!-- 自动生成的配置 -->
                <configurationFile>
src/main/resources/mybatis/mybatis-generator.xml</configurationFile>
            </configuration>
        </plugin>
    </plugins>
</build>
4、执行
