作用:自动生成模板代码和实体类,简化开发人员工作,降低错误率。
前置配置,去除指定前缀(“sys_”改成你要去掉的前缀)
##初始化区域
##去掉表的t_前缀
$!tableInfo.setName($tool.getClassName($tableInfo.obj.name.replaceFirst("sys_","")))
##参考阿里巴巴开发手册,POJO 类中布尔类型的变量,都不要加 is 前缀,否则部分框架解析会引起序列化错误
#foreach($column in $tableInfo.fullColumn)
#if($column.name.startsWith("is") && $column.type.equals("java.lang.Boolean"))
$!column.setName($tool.firstLowerCase($column.name.substring(2)))
#end
#end
##实现动态排除列
#set($temp = $tool.newHashSet("testCreateTime", "otherColumn"))
#foreach($item in $temp)
#set($newList = $tool.newArrayList())
#foreach($column in $tableInfo.fullColumn)
#if($column.name!=$item)
##带有反回值的方法调用时使用$tool.call来消除返回值
$tool.call($newList.add($column))
#end
#end
##重新保存
$tableInfo.setFullColumn($newList)
#end
##对importList进行篡改
#set($temp = $tool.newHashSet())
#foreach($column in $tableInfo.fullColumn)
#if(!$column.type.startsWith("java.lang."))
##带有反回值的方法调用时使用$tool.call来消除返回值
$tool.call($temp.add($column.type))
#end
#end
##覆盖
#set($importList = $temp)
1.entity-注意if下面留空格,不然影响下一行对齐,造成下一行错位
##导入宏定义
$!init
$!define
##保存文件(宏定义)
#save("/entity", ".java")
