枚举根据参数获取值

问题背景

业务中经常会遇到固定业务类型，数据库中常常以数值依次标识其含义 0-女 1-男

主体思路：

定义枚举》获取枚举中得值组成map生成bean》通过上下文获取bean获取对应的值

枚举

import lombok.Getter;
import lombok.Setter;

/**
 * @author Xuewei.Zhang
 * @date 2022/7/5
 */
public enum FlowEnum {

    ORDER(0, "订单"),
    PROCUREMENT(1, "采购"),
    PRODUCTION(2, "生产"),
    REIMBURSE(3, "报销"),
    VACATE(4, "请假"),
    ;

    @Getter
    @Setter
    private Integer code;

    @Getter
    @Setter
    private String msg;

    FlowEnum(Integer code, String msg) {
        this.code = code;
        this.msg = msg;
    }

}

组装bean

import com.zxw.common.core.base.enums.FlowEnum;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;

/**
 * @author Xuewei.Zhang
 * @date 2022/7/5
 */
@Configuration
public class FlowBean {

    @Bean("FlowEnumBean")
    public Map<String, Integer> FlowEnumBean() {
        Map<String, Integer> map = new ConcurrentHashMap<>();
        for (FlowEnum flowEnum : FlowEnum.values()) {
            map.put(flowEnum.getMsg(), flowEnum.getCode());
        }
        return map;
    }
}

获取对应的值

import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Configuration;

import javax.annotation.Resource;
import java.util.Map;

/**
 * @author Xuewei.Zhang
 * @date 2022/7/5
 */
@Configuration
public class BeanUtils {

    private static ApplicationContext applicationContext;

    @Resource
    public void setApplicationContext(ApplicationContext applicationContext) {
        BeanUtils.applicationContext = applicationContext;
    }

    public  static Integer getCodeByServiceName(String serviceName) {
        Map<String, Integer> map = (Map<String, Integer>) applicationContext.getBean("FlowEnumBean");
        return map.get(serviceName);
    }

}

使用

    @Override
    @InitInsertInfo
    public FlowTypeVO add(FlowTypeVO flowTypeVO) {
     //使用        
flowTypeVO.setServiceType(BeanUtils.getCodeByServiceName(flowTypeVO.getServiceTypeName()));
        flowTypeMapper.insert(flowTypeVO);
        return flowTypeVO;
    }

测试结果：
