1.entity.java

##引入宏定义
$!define

##使用宏定义设置回调（保存位置与文件后缀）
#save("/entity", ".java")

##使用宏定义设置包后缀
#setPackageSuffix("entity")

##使用全局变量实现默认包导入
$!autoImport
import java.io.Serializable;

##使用宏定义实现类注释信息
#tableComment("实体类")
public class $!{tableInfo.name} implements Serializable {
    private static final long serialVersionUID = $!tool.serial();
#foreach($column in $tableInfo.fullColumn)
    #if(${column.comment})/**
    * ${column.comment}
    */#end

    private $!{tool.getClsNameByFullName($column.type)} $!{column.name};
#end
    private Integer startRow;//首行
    private Integer pageSize;//页容量
    private Integer pageNum;//页码

#foreach($column in $tableInfo.fullColumn)
##使用宏定义实现get,set方法
#getSetMethod($column)
#end
    public Integer getStartRow() {
        return startRow;
    }

    public void setStartRow(Integer startRow) {
        this.startRow = startRow;
    }

    public Integer getPageSize() {
        return pageSize;
    }

    public void setPageSize(Integer pageSize) {
        this.pageSize = pageSize;
    }

    public Integer getPageNum() {
        return pageNum;
    }

    public void setPageNum(Integer pageNum) {
        this.pageNum = pageNum;
    }

}

2.dao.java

##定义初始变量
#set($tableName = $tool.append($tableInfo.name, "Dao"))
##设置回调
$!callback.setFileName($tool.append($tableName, ".java"))
$!callback.setSavePath($tool.append($tableInfo.savePath, "/dao"))

##拿到主键
#if(!$tableInfo.pkColumn.isEmpty())
    #set($pk = $tableInfo.pkColumn.get(0))
#end

#if($tableInfo.savePackageName)package $!{tableInfo.savePackageName}.#{end}dao;

import $!{tableInfo.savePackageName}.entity.$!{tableInfo.name};
import org.apache.ibatis.annotations.Param;
import java.util.List;

/**
 * $!{tableInfo.comment}($!{tableInfo.name})表数据库访问层
 *
 * @author wangxin
 * @since $!time.currTime()
 */
public interface $!{tableName} {


    List<$!{tableInfo.name}> selectPage($!{tableInfo.name} $!tool.firstLowerCase($!{tableInfo.name}));

    int getCount($!{tableInfo.name} $!tool.firstLowerCase($!{tableInfo.name}));
    
    List<$!{tableInfo.name}> selectAll($!{tableInfo.name} $!tool.firstLowerCase($!{tableInfo.name}));

    $!{tableInfo.name} selectByPrimaryKey($!pk.shortType $!pk.name);
    
    int insert($!{tableInfo.name} $!tool.firstLowerCase($!{tableInfo.name}));
    
    int insertSelective($!{tableInfo.name} $!tool.firstLowerCase($!{tableInfo.name}));

    int updateByPrimaryKey($!{tableInfo.name} $!tool.firstLowerCase($!{tableInfo.name}));

    int deleteById($!pk.shortType $!pk.name);

}

3.mapper.xml

##引入mybatis支持
$!mybatisSupport

##设置保存名称与保存位置
$!callback.setFileName($tool.append($!{tableInfo.name}, "Dao.xml"))
$!callback.setSavePath($tool.append($modulePath, "/src/main/resources/mapper"))

##拿到主键
#if(!$tableInfo.pkColumn.isEmpty())
    #set($pk = $tableInfo.pkColumn.get(0))
#end
