模板文件：

在resources文件夹下新建templates文件夹：放入controller.java.vm与query.java.vm模板

controller.java.vm

package ${package.Controller};

import ${package.Service}.${table.serviceName};
import ${package.Entity}.${entity};
import cn.lin.query.${entity}Query;
import cn.lin.util.AjaxResult;
import cn.lin.util.PageList;
import com.baomidou.mybatisplus.plugins.Page;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.List;

@RestController
@RequestMapping("/${table.entityPath}")
public class ${entity}Controller {
    @Autowired
    public ${table.serviceName} ${table.entityPath}Service;

    /**
     * 保存和修改公用的
     * @param ${table.entityPath} 传递的实体
     * @return Ajaxresult转换结果
     */
    @RequestMapping(value = "/save", method = RequestMethod.POST)
    public AjaxResult save(@RequestBody ${entity} ${table.entityPath}) {
        try {
            if (${table.entityPath}.getId() != null){
                    ${table.entityPath}Service.updateById(${table.entityPath});
            }else{
                    ${table.entityPath}Service.insert(${table.entityPath});
            }
            return AjaxResult.me();
        } catch (Exception e) {
            e.printStackTrace();
            return AjaxResult.me().setSuccess(false).setMessage("保存对象失败！" + e.getMessage());
        }
    }

    /**
    * 删除对象信息
    * @param id
    * @return
    */
    @RequestMapping(value = "/{id}", method = RequestMethod.DELETE)
    public AjaxResult delete(@PathVariable("id") Long id) {
        try {
                ${table.entityPath}Service.deleteById(id);
            return AjaxResult.me();
        } catch (Exception e) {
            e.printStackTrace();
            return AjaxResult.me().setSuccess(false).setMessage("删除对象失败！" + e.getMessage());
        }
    }

    //获取用户
    @RequestMapping(value = "/{id}", method = RequestMethod.GET)
    public ${entity} get(@PathVariable("id") Long id) {
        return ${table.entityPath}Service.selectById(id);
    }


    /**
    * 查看所有的员工信息
    * @return
    */
    @RequestMapping(value = "/list", method = RequestMethod.GET)
    public List<${entity}> list() {

        return ${table.entityPath}Service.selectList(null);
    }


    /**
    * 分页查询数据
    *
    * @param query 查询对象
    * @return PageList 分页对象
    */
    @RequestMapping(value = "/pagelist", method = RequestMethod.POST)
    public PageList<${entity}> json(@RequestBody ${entity}Query query) {
        Page<${entity}> page = new Page<${entity}>(query.getPage(), query.getRows());
        page = ${table.entityPath}Service.selectPage(page);
        return new PageList<${entity}>(page.getTotal(), page.getRecords());
    }
}

query.java.vm

package ${package.query};

/**
 * @author ${author}
 * @since ${date}
 */
public class ${table.entityName}Query extends BaseQuery{
}

所需jar包：

   <!--导入mybatis-plus包-->
   <dependency>
       <groupId>com.baomidou</groupId>
       <artifactId>mybatis-plus-boot-starter</artifactId>
       <version>2.2.0</version>
   </dependency>

   <!--连接数据库-->
   <dependency>
       <groupId>mysql</groupId>
       <artifactId>mysql-connector-java</artifactId>
   </dependency>

   <!--模板引擎-->
   <dependency>
       <groupId>org.apache.velocity</groupId>
       <artifactId>velocity-engine-core</artifactId>
       <version>2.0</version>
   </dependency>	

使用的服务中需要MybatisPlusConfig

import com.baomidou.mybatisplus.plugins.PaginationInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.transaction.annotation.EnableTransactionManagement;

//Spring boot方式
@Configuration
@MapperScan("cn.lin.ffs.mapper") //mapper接口扫描
@EnableTransactionManagement  //事务管理
public class MybatisPlusConfig {

    @Bean
    public PaginationInterceptor paginationInterceptor() {
        return new PaginationInterceptor();
    }
}

主类上不需要@MapperScan

application.yml中加入
