枚舉的內容可以使用map的方式

下面是繼承的示例

public enum OracleErrorTypeEnum implements BaseEnum  {DemandTask("DemandTask","需求調查任務"),DemandReport("DemandReport","需求調查填報"),DemandSummary("DemandSummary","需求調查匯總"),NEEDS_SURVEY( "NEEDS_SURVEY","需求調查業務");private String key;private String value;/*構造函數*/private OracleErrorTypeEnum(String key, String value) {this.key = key;this.value = value;}public String getKey() {return key;}public void setKey(String key) {this.key = key;}public String getValue() {return value;}public void setValue(String value) {this.value = value;}}
