java+ 如何动态配置业务规则组-编程知识

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',`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 `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 {@Overridepublic Object promotiona(Object o) {return "promotiona:" + o;}@Overridepublic Object interpersonalConnections(Object o) {return "interpersonalConnections:" + o;}@Overridepublic Object education(Object o) {return "education";}@Overridepublic Object alternatedays(Object o) {return "alternatedays：" + o;}@Overridepublic Object kinship(Object o) {return "kinship：" + o;}@Overridepublic Object staffinfoUpdate(Object o) {return "staffinfoUpdate";}@Overridepublic Object deleteSchedulingRecord(Object o) {return "deleteSchedulingRecord";}@Overridepublic Object revocationSign(Object o) {return "revocationSign";}@Overridepublic 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();Method method = clazz.getDeclaredMethod(methodName);Object result = method.invoke(staffMoveService);System.out.println(result);} catch (NoSuchMethodException | IllegalAccessException | InvocationTargetException e) {e.printStackTrace();return ResultVo.failure();}}}return ResultVo.ok("success");}
}
