groovyでマップを使用してExcelを書く

Question

groovyでマップを使用してExcelファイルを作成しようとしています。これはグルーヴィーで行うことができますどのように

//writing data in the map 
Map < String, Object[] > empinfo = new TreeMap < String, Object[] >(); 
    empinfo.put("1", new Object[] {"EMP ID", "EMP NAME", "DESIGNATION" }); 
    empinfo.put("2", new Object[] {"", "Gopal", "Technical Manager" }); 
    empinfo.put("7", new Object[] {"tp02", "Manisha", "Proof Reader" }); 
    empinfo.put("4", new Object[] {"tp03", "", "Technical Writer" }); 
    empinfo.put("5", new Object[] {"tp04", "Satish", "Technical Writer" }); 
    empinfo.put("6", new Object[] {"tp05", "Krishna", "" }); 

    //Iterate over data and write to sheet 
    Set <String> keyid = empinfo.keySet(); 
    int rowid = 0; 
    for (String key : keyid) 
    { 
    row = spreadsheet.createRow(rowid++); 
    Object [] objectArr = empinfo.get(key); 
    int cellid = 0; 
    for (Object obj : objectArr) 
    { 
     Cell cell = row.createCell(cellid++); 
     cell.setCellValue((String)obj); 
    } 
    } 

以下に示すようにJavaで は、私は私のマップ内の値を入力するのですか？ 私はgroovyを初めて使用しており、どんな助力も高く評価されています。

Answer 1

groovyがこのような配列宣言構文をサポートしていないため、groovy.lang.MissingMethodExceptionが得られます。ここで

Groovy array declaration

Groovy map declaration

あなたは猫の皮を剥ぐために複数の方法がありますTreeMapの

def empinfo = new TreeMap<String, Object[]>(); 

empinfo["1"] = ["EMP ID", "EMP NAME", "DESIGNATION"] as Object[]; 
empinfo["2"] = ["", "Gopal", "Technical Manager"] as Object[]; 
empinfo["7"] = ["tp02", "Manisha", "Proof Reader"] as Object[]; 
empinfo["4"] = ["tp03", "", "Technical Writer"] as Object[]; 
empinfo["5"] = ["tp04", "Satish", "Technical Writer"] as Object[]; 
empinfo["6"] = ["tp05", "Krishna", ""] as Object[]; 

または

TreeMap empinfo = [ 
    "1": ["EMP ID", "EMP NAME", "DESIGNATION"] as Object[], 
    "2": ["", "Gopal", "Technical Manager"] as Object[], 
    "7": ["tp02", "Manisha", "Proof Reader"] as Object[], 
    "4": ["tp03", "", "Technical Writer"] as Object[], 
    "5": ["tp04", "Satish", "Technical Writer"] as Object[], 
    "6": ["tp05", "Krishna", ""] as Object[] 
]; 

Answer 2

を宣言することができる方法である。

// writing data in the map 
def empinfo = [ 
    "1" : ["EMP ID", "EMP NAME", "DESIGNATION"], 
    "2" : ["", "Gopal", "Technical Manager"], 
    "3" : ["tp02", "Manisha", "Proof Reader"], 
    "4" : ["tp03", "", "Technical Writer"], 
    "5" : ["tp04", "Satish", "Technical Writer"], 
    "6" : ["tp05", "Krishna", ""] 
] 

short rowid = 0 
empinfo.each { key, value -> 
    row = spreadsheet.createRow(rowid++) 
    short cellid = 0 
    value.each { item -> 
     def cell = row.createCell(cellid++) 
     cell.setCellValue(item) 
    } 
} 

"Groovyness"をどれくらい持ちたいかはあなた次第です。
