Intellij Idea中定制getter setter的模板

如果不想用lombok, 但是又希望代码尽量简洁, 可以用定制getter和setter方法的方式, 让代码尽量紧凑显示

目标格式

public class DemoClass {
    private String columnName;
    private String varName;
    private Class<?> varType;
    private boolean primary;
    private boolean autoIncrement;
    private boolean sortable;

    public String getColumnName() {return columnName;}
    public void setColumnName(String columnName) {this.columnName = columnName;}
    public String getVarName() {return varName;}
    public void setVarName(String varName) {this.varName = varName;}
    public Class<?> getVarType() {return varType;}
    public void setVarType(Class<?> varType) {this.varType = varType;}
    public boolean isPrimary() {return primary;}
    public void setPrimary(boolean primary) {this.primary = primary;}
    public boolean isAutoIncrement() {return autoIncrement;}
    public void setAutoIncrement(boolean autoIncrement) {this.autoIncrement = autoIncrement;}
    public boolean isSortable() {return sortable;}
    public void setSortable(boolean sortable) {this.sortable = sortable;}
}

设置 getter setter 模板

Alt + Ins, 调出快捷菜单后选择 Getter and Setter, 在对话框里, 选择对应的template, 右侧点开后, 可以新建自己的模板并编辑

将getter生成到一行的模板,

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

将setter生成到一行的模板

#set($paramName = $helper.getParamName($field, $project))
#if($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;}

因为实际的模板, 会跟随着Idea的版本不断变化, 所以上面的模板并非符合所有情况, 建议的修改方式是用IntelliJ Default复制一份在这个基础上改, 如果被条件语句隔开导致换行, 而你又不希望换行的地方, 可以用##表示不换行.

设置格式避免被格式化自动换行

上面的模板设置完会发现无效, 是因为在写入到编辑器时, 被编辑器的自动格式化换行了. 需要进行以下设置

1. 打开设置界面 Settings / Editor / Code Style / Java
2. Wrapping and Braces 下, 勾选Keep when reformatting 下
   • Line breaks
   • Comment at first column
   • Control statement in one line
   • Simple methods in one line
3. Blank Lines, Minimum blank lines 下
   • Around method in interface 改为 0
   • Around method 改为 0
