> 思路
> 
> 1. 实现在页面上的动态配置规则组（2张数据表+枚举类+service+impl+action）
> 
> 2. 从数据库中表staffmoverules（规则明细表）或者staffmovetyperule（规则组表） ，根据传入类型，取出规则编号
> 
> 3. 根据规则编号反射找到对应的方法名
> 
> 4. 执行对应方法

1. 页面上实现手工配置

CREATE TABLE `staffmoverules` (
      `rulenumber` int DEFAULT NULL COMMENT '规则组编号',
      `movetype` varchar(50) DEFAULT NULL COMMENT '使用类型',
      `message` varchar(500) DEFAULT NULL COMMENT '规则说明',
      `operationtype` varchar(50) DEFAULT NULL COMMENT '操作类型',
      `createtime` datetime DEFAULT NULL COMMENT '创建时间',

      `lastermodifier` varchar(100) DEFAULT NULL COMMENT '最近修改人',
      `lastertime` datetime DEFAULT NULL COMMENT '最近修改时间',
      `id` varchar(100) DEFAULT NULL,
      UNIQUE KEY `staffmoverules_rulenumber_IDX` (`rulenumber`) USING BTREE
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci COMMENT='人员调度规则明细'

CREATE TABLE `staffmovetyperule` (
      `movetype` varchar(50) DEFAULT NULL COMMENT '规则组类型',
      `message` varchar(500) DEFAULT NULL COMMENT '规则说明',
      `createtime` datetime DEFAULT NULL COMMENT '创建时间',
      `creator` varchar(100) DEFAULT NULL COMMENT '创建者',
      `lastermodifier` varchar(100) DEFAULT NULL COMMENT '最近修改人',
      `lastertime` datetime DEFAULT NULL COMMENT '最近修改时间',
      `id` varchar(100) DEFAULT NULL,
      UNIQUE KEY `staffmovetyperule_movetype_IDX` (`movetype`) USING BTREE
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci COMMENT='人员调度规则组校验'

2. 枚举类

package com.hrs.controller.rules;
    
    public enum StaffMoveRulesEnum {
       //规则组配置数据库里：2张表 //1.配置规则组 、2 具体的规则
        //ehr页面上可以配置 规则组跟 具体规则，设置权限
        //internal recruitmen-- IR 内部招聘，Staff regularization-- SR 转正
        //1XXX--OA,2xxx-IR,3xxx-SR,4xxx-public
    
        //OA规则
        PROMOTIONA(1001,"OA","晋升提拔","check","promotiona"),
        INTERPERSONALCONNECTIONS(1002,"OA","人脉关系","check","interpersonalConnections"),
    
        //内招规则
        EDUCATION(2001,"IR","学历","check","education"),
    
        //人员转正规则
        ALTERNATEDAYS(3001,"SR","调休天数","check","alternatedays"),
    
        //共有规则
        KINSHIP(4001,"PUBLIC","上下级亲属关系","check","kinship"),
        STAFFINFOUPDATE(4002,"PUBLIC","人员信息更新","update","staffinfoUpdate"),
        DELETESCHEDULINGRECORD(4003,"PUBLIC","删除调度关系","C","deleteSchedulingRecord"),
        REVOCATIONSIGN(4004,"PUBLIC","撤销电子签","revocation","revocationSign"),
        RESOURCEALLOCATIONNOTIFICATION(4005,"PUBLIC","资源配置通知","inform","resourceAllocationNotification");
    
    
    
        public int ruleNumber;//规则编码
        String moveType;//使用类型
        String message;//说明
    
        String operationType;//操作类型
    
        String methodName;//方法名
    
        public int getRuleNumber() {
            return ruleNumber;
        }
    
        public void setRuleNumber(int ruleNumber) {
            this.ruleNumber = ruleNumber;
        }
    
        public String getMethodName() {
            return methodName;
        }
    
        public void setMethodName(String methodName) {
            this.methodName = methodName;
        }
    
    
    
        public String getMoveType() {
            return moveType;
        }
    
        public void setMoveType(String moveType) {
            this.moveType = moveType;
        }
    
        public String getMessage() {
            return message;
        }
    
        public void setMessage(String message) {
            this.message = message;
        }
    
        public String getOperationType() {
            return operationType;
        }
    
        public void setOperationType(String operationType) {
            this.operationType = operationType;
        }
    
        StaffMoveRulesEnum(int ruleNumber, String moveType, String message, String operationType, String methodName) {
            this.ruleNumber = ruleNumber;
            this.moveType = moveType;
            this.message = message;
            this.operationType = operationType;
            this.methodName = methodName;
        }
    }

3. service 、impl类

package com.hrs.service;
    
    import org.springframework.stereotype.Service;
    
    @Service
    public interface StaffMoveService {
        Object promotiona(Object o);
        Object interpersonalConnections(Object o);
        Object education(Object o);
        Object alternatedays(Object o);
        Object kinship(Object o);
        Object staffinfoUpdate(Object o);
        Object deleteSchedulingRecord(Object o);
        Object revocationSign(Object o);
        Object resourceAllocationNotification(Object o);
    }

package com.hrs.service;
    
    import com.hrs.service.StaffMoveService;
    import org.springframework.stereotype.Service;
    
    @Service
    public class StaffMoveImpl implements StaffMoveService {
    
        @Override
        public Object promotiona(Object o) {
            return "promotiona:" + o;
        }
    
        @Override
        public Object interpersonalConnections(Object o) {
            return "interpersonalConnections:" + o;
        }
    
        @Override
        public Object education(Object o) {
            return "education";
        }
    
        @Override
        public Object alternatedays(Object o) {
            return "alternatedays：" + o;
        }
    
        @Override
        public Object kinship(Object o) {
            return "kinship：" + o;
        }
    
        @Override
        public Object staffinfoUpdate(Object o) {
            return "staffinfoUpdate";
        }
    
        @Override
        public Object deleteSchedulingRecord(Object o) {
            return "deleteSchedulingRecord";
        }
    
        @Override
        public Object revocationSign(Object o) {
            return "revocationSign";
        }
    
        @Override
        public Object resourceAllocationNotification(Object o) {
            return "resourceAllocationNotification";
        }
    }

4 action类

package com.hrs.controller.rules;
    
    import com.hrs.entity.ResultVo;
    import com.hrs.service.StaffMoveService;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.web.bind.annotation.PostMapping;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    import java.lang.reflect.InvocationTargetException;
    import java.lang.reflect.Method;
    import java.util.ArrayList;
    import java.util.List;
    
    public class StaffMoveAction {
        StaffMoveService staffMoveService;
        public ResultVo adjust(Object o){
            String type;//从入参中取出
            //1.从数据库中表staffmoverules或者staffmovetyperule 取出规则编号
            //List<Integer> rulesNumber = ucc.adjutst();
            List<Integer> rulesNumber = new ArrayList<>();
            rulesNumber.add(1001);
            rulesNumber.add(1002);
            //2.
            // 根据规则编号找到对应的枚举值
            for (StaffMoveRulesEnum rule : StaffMoveRulesEnum.values()){
                    if (rulesNumber.contains(rule.ruleNumber)){
                        // 获取对应的方法名
                        String methodName = rule.getMethodName();
                        // 通过反射执行对应的方法
                        try {
                            Class<?> clazz = staffMoveService.getClass();
                            Class<?>[] parameterTypes = new Class<?>[]{Object.class}; // 传入Object类型参数
                            Method method = clazz.getDeclaredMethod(methodName,parameterTypes);
                            Object result = method.invoke(staffMoveService,o);
                            System.out.println(result);
                        } catch (NoSuchMethodException | IllegalAccessException | InvocationTargetException e) {
                            e.printStackTrace();
                            return ResultVo.failure();
                        }
                    }
            }
            return ResultVo.ok("success");
        }
    }
