springboot搭建通用mapper代码自动生成器

1.采用tk.mybatis.mapper包

pom包引入

<dependency>
            <groupId>tk.mybatis</groupId>
            <artifactId>mapper-spring-boot-starter</artifactId>
            <version>${mapper.version}</version>
            <exclusions>
                <exclusion>
                    <artifactId>mybatis-spring-boot-starter</artifactId>
                    <groupId>org.mybatis.spring.boot</groupId>
                </exclusion>
           </exclusions>
 </dependency>

pom内build的引用

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            &lt;!&ndash; mybatis generator自动生成代码 &ndash;&gt;

                    </execution>
                </executions>
                <configuration>

                </configuration>
            </plugin>
        </plugins>
    </build>
