Intellij Idea中定制getter setter的模板, 将代码都生成为一行

1 Alt + Insert, 调出快捷菜单后选择 Getter and Setter

2 选择 Getter and Setter 后会到如下界面

3 如下图，点击右边第①步，然后第②步点击+号，添加模板，第③步是添加模板内容

4 模板内容如下

Getter

public ##
#if($field.modifierStatic)
  static ##
#end
$field.type ##
#set($name = $StringUtil.capitalizeWithJavaBeanConvention($StringUtil.sanitizeJavaIdentifier($helper.getPropertyName($field, $project))))
#if ($field.boolean)
  #if ($StringUtil.startsWithIgnoreCase($name, 'is'))
    #set($name = $StringUtil.decapitalize($name))
  #else
    is##
#end
#else
  get##
#end
${name}() { return $field.name; }

Setter

#set($paramName = $helper.getParamName($field, $project))
public ##
#if($field.modifierStatic)
  static ##
#end
void set$StringUtil.capitalizeWithJavaBeanConvention($StringUtil.sanitizeJavaIdentifier($helper.getPropertyName($field, $project)))($field.type $paramName) {##
  #if ($field.name == $paramName)
    #if (!$field.modifierStatic)
      this.##
    #else
      $classname.##
    #end
  #end
$field.name = $paramName; }

5 最后一步， 修改Settings / Editor / Code Style / Java / Wrapping and Braces 下, 勾选Keep when reformatting下的"Simple methods in one line"
