列挙+ダイナミック反射

列挙クラスの作成:

public enum TableEnum {
     

    ENUMONE("key1","method1"),
    ENUMTWO("key2","method2"),
    ENUMTHREE("key3","method3"),
    ENUMFOUR("key4","method4"),
    ENUMFIVE("key5","method5");

    private String key;

    private String value;

    TableEnum() {
     
    }

    TableEnum(String key, String value) {
     
        this.key = key;
        this.value = value;
    }

    private String key() {
     
        return this.key;
    }

    private String value() {
     
        return this.value;
    }


    public static String getValue(String key) {
     
        TableEnum[] tableEnums = values();
        for (TableEnum tableEnum : tableEnums) {
     
            if (tableEnum.key().equals(key)) {
     
                return tableEnum.value();
            }
        }
        return null;
    }

}

メソッドによって列挙クラスの対応する値が反射によって除去される方法を見つける

    public int createTable(String projectId,String tableName) {
     
        int count = 0;;
        String key = tableName.split("_")[2];
        String value = TableEnum.getValue(key);
        Class<? extends CreateTableServiceImpl> aClass = SpringUtils.getBean(CreateTableServiceImpl.class).getClass();
        try {
     
            Method method = aClass.getMethod(value, String.class);
            method.invoke(aClass.newInstance(),tableName);
            count = 1;
        } catch (Exception e) {
     
            e.printStackTrace();
        }
        return count;
    }
