将枚举内容放到Map中

将枚举内容放到Map中，简单方法如下

import java.util.Map;
import java.util.TreeMap;
import com.example.demo.utils.JacksonUtils;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
public class EnumToMapTest {

    @Test
    public void test() {
        Map<String, PayType> toMap = PayType.toMap();
        System.out.println(JacksonUtils.beanToJson(toMap));
    }

    enum PayType {

        ALIPAY("支付宝扫码", 1),
        WEIXIN_PAY("微信扫码", 2);

        PayType(String name, int value) {
            this.name = name;
            this.value = value;
        }

        public String name;
        public int value;

        public static Map<String, PayType> toMap() {
            Map<String, PayType> map = new TreeMap<>();
            PayType[] types = PayType.values();
            for (PayType type : types) {
                map.put(String.valueOf(type.value), type);
            }
            return map;
        }
    }
}

执行测试结果
