问题描述：使用MyBatis Generator自动生成映射的时候报错 No plugin found for prefix ‘mybatis-generator’ in the current project and in the plugin groups 在当前项目和插件组中没有找到前缀’ mybatisi -generator’的插件

 1.在pom.xml添加

   <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
                <configuration>
                    <configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
                    <overwrite>true</overwrite>
                    <verbose>true</verbose>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>8.0.11</version>
                    </dependency>
                    <dependency>
                        <groupId>org.mybatis.generator</groupId>
                        <artifactId>mybatis-generator-core</artifactId>
                        <version>1.3.2</version>
                    </dependency>
                </dependencies>
            </plugin>

数据库连接修改为：connectionURL="jdbc:mysql://localhost:3306/gmall?useUnicode=true&characterEncoding=utf8&useSSL=false"
