作用:自動生成模板代碼和實體類,簡化開發(fā)人員工作,降低錯誤率。
前置配置,去除指定前綴(“sys_”改成你要去掉的前綴)
##初始化區(qū)域
##去掉表的t_前綴
$!tableInfo.setName($tool.getClassName($tableInfo.obj.name.replaceFirst("sys_","")))
##參考阿里巴巴開發(fā)手冊,POJO 類中布爾類型的變量,都不要加 is 前綴,否則部分框架解析會引起序列化錯誤
#foreach($column in $tableInfo.fullColumn)
#if($column.name.startsWith("is") && $column.type.equals("java.lang.Boolean"))
$!column.setName($tool.firstLowerCase($column.name.substring(2)))
#end
#end
##實現(xiàn)動態(tài)排除列
#set($temp = $tool.newHashSet("testCreateTime", "otherColumn"))
#foreach($item in $temp)
#set($newList = $tool.newArrayList())
#foreach($column in $tableInfo.fullColumn)
#if($column.name!=$item)
##帶有反回值的方法調(diào)用時使用$tool.call來消除返回值
$tool.call($newList.add($column))
#end
#end
##重新保存
$tableInfo.setFullColumn($newList)
#end
##對importList進行篡改
#set($temp = $tool.newHashSet())
#foreach($column in $tableInfo.fullColumn)
#if(!$column.type.startsWith("java.lang."))
##帶有反回值的方法調(diào)用時使用$tool.call來消除返回值
$tool.call($temp.add($column.type))
#end
#end
##覆蓋
#set($importList = $temp)
1.entity-注意if下面留空格,不然影響下一行對齊,造成下一行錯位
