Java 枚举模版

Posted 2022-12-09 AAA啊哈

项目中使用枚举，为了方便，编辑了模版，每次都能自动生成这些轮子：

#if ($PACKAGE_NAME != "")package $PACKAGE_NAME;#end

import java.util.HashMap;

#if ($IMPORT_BLOCK != "")$IMPORT_BLOCK
#end
#parse("File Header.java")

#if ($VISIBILITY == "PUBLIC")public #end enum $NAME #if ($INTERFACES != "")implements $INTERFACES #end 

    ONE(1, "one"),
    TWO(2, "two"),
    ;

    private Integer value;

    private String desc;


    $NAME(Integer value, String desc) 
        this.value = value;
        this.desc = desc;
    

    public String getDesc() 
        return desc;
    

    public void setDesc(String desc) 
        this.desc = desc;
    

    public Integer getValue() 
        return value;
    

    public void setValue(Integer value) 
        this.value = value;
    


    public static Integer getValueByDesc(String desc)
        for ($NAME enumItem : $NAME.values()) 
            if(enumItem.getDesc().equals(desc))
                return enumItem.getValue();
            
        
        return -1;
    

    public static String getDescByValue(Integer value)
        for ($NAME enumItem : $NAME.values()) 
            if(enumItem.getValue().equals(value))
                return enumItem.getDesc();
            
        
        return "";
    

    public static HashMap<Integer, String> getMapData() 
        HashMap<Integer, String> map = new HashMap<>();
        for ($NAME enumItem : $NAME.values()) 
            map.put(enumItem.getValue(), enumItem.getDesc());
        
        return map;
