我需要這些分隔的數據轉換成JSON格式。請指教。

你可以做一些拆分和替換操作。下面是Java內容中的一個示例，您可以將其轉換爲json格式，調用toJsonArr方法。

public static String toJsonArr(String src){ 
    StringBuilder builder = new StringBuilder(); 
    String objArray[] = src.split("\\|R\\|\\|L\\|"); 
    builder.append("["); 
    for(String obj : objArray){ 
     builder.append(toJsonObj(obj)).append(","); 
    } 

    //remove last comma , 
    String str = builder.substring(0, builder.length()-1); 

    return str+"]"; 
} 

public static String toJsonObj(String src){ 
    StringBuilder builder = new StringBuilder(); 
    String elemArray[] = src.split("\\|L\\|"); 
    builder.append("{"); 
    for(String elem : elemArray){ 
        //for empty lines 
     if(elem.trim().length()!=0) 
      builder.append(toJsonElem(elem)).append(","); 
    } 

    //remove last comma , 
    String str = builder.substring(0, builder.length()-1); 

    return str+"}"; 
} 

public static String toJsonElem(String src){ 
    StringBuilder builder = new StringBuilder(); 
    builder.append("\"").append(src.trim().replaceAll("\\|\\|", "\":\"")).append("\""); 
    return builder.toString(); 
}
