其实审批的本质就是两张表,一个审批状态表,一个审批表本身,审批流程的过程就是状态管理的过程。

为实现完整的请假申请流程,需要引入审批流的概念。这个流程不仅包括申请人提交申请,还包括选择审批人、审批操作(同意/驳回)以及状态的变更等功能。下面将详细介绍如何通过若依框架的 MVC 模式来实现请假申请和审批流程。

### 1. 需求分析

完整的业务流程包含以下步骤:

1. 用户填写请假申请。
2. 用户选择审批人,并提交申请。
3. 审批人查看待审批的申请,并决定批准或驳回。
4. 若审批通过,申请状态变为“已通过”;若驳回,状态变为“已驳回”。

### 2. 数据库表设计

为了支持审批功能,除了基本的请假申请数据表,还需要一个审批记录表来跟踪每个审批过程的状态。

**表1:`sys_leave_request`** (请假申请表)
```sql
CREATE TABLE sys_leave_request (
    request_id BIGINT PRIMARY KEY AUTO_INCREMENT,
    leave_type VARCHAR(50),       -- 请假类型
    start_time DATETIME,          -- 开始时间
    end_time DATETIME,            -- 结束时间
    reason TEXT,                  -- 请假原因
    applicant VARCHAR(50),        -- 申请人
    status VARCHAR(20),           -- 状态(待审批、已通过、已驳回)
    approver VARCHAR(50),         -- 审批人
    create_time DATETIME DEFAULT CURRENT_TIMESTAMP
);
```

**表2:`sys_leave_approval`** (审批记录表)
```sql
CREATE TABLE sys_leave_approval (
    approval_id BIGINT PRIMARY KEY AUTO_INCREMENT,
    request_id BIGINT,            -- 对应的请假申请ID
    approver VARCHAR(50),         -- 审批人
    approval_status VARCHAR(20),  -- 审批状态(同意、驳回)
    approval_time DATETIME,       -- 审批时间
    comments TEXT                 -- 审批意见
);
```

### 3. 数据模型(Model)

**请假申请实体类:`LeaveRequest`**
```java
package com.ruoyi.project.system.leave.domain;

import java.util.Date;

public class LeaveRequest {
    private Long requestId;
    private String leaveType;
    private Date startTime;
    private Date endTime;
    private String reason;
    private String applicant;
    private String status;
    private String approver;

    // Getters 和 Setters 略
}
```

**审批记录实体类:`LeaveApproval`**
```java
package com.ruoyi.project.system.leave.domain;

import java.util.Date;

public class LeaveApproval {
    private Long approvalId;
    private Long requestId;
    private String approver;
    private String approvalStatus;
    private Date approvalTime;
    private String comments;

    // Getters 和 Setters 略
}
```

### 4. 数据库操作(Mapper)

#### 4.1 请假申请 Mapper

```java
package com.ruoyi.project.system.leave.mapper;

import com.ruoyi.project.system.leave.domain.LeaveRequest;
import java.util.List;

public interface LeaveRequestMapper {
    List<LeaveRequest> selectAllRequests();
    
    LeaveRequest selectRequestById(Long requestId);
    
    int insertLeaveRequest(LeaveRequest leaveRequest);
    
    int updateLeaveRequest(LeaveRequest leaveRequest);
    
    int deleteLeaveRequestById(Long requestId);
    
    // 查询待审批的申请
    List<LeaveRequest> selectPendingRequests(String approver);
}
```

#### 4.2 审批记录 Mapper

```java
package com.ruoyi.project.system.leave.mapper;

import com.ruoyi.project.system.leave.domain.LeaveApproval;
import java.util.List;

public interface LeaveApprovalMapper {
    List<LeaveApproval> selectApprovalsByRequestId(Long requestId);
    
    int insertLeaveApproval(LeaveApproval leaveApproval);
}
```

### 5. 服务层(Service)

#### 5.1 请假申请服务接口

```java
package com.ruoyi.project.system.leave.service;

import com.ruoyi.project.system.leave.domain.LeaveRequest;
import java.util.List;

public interface ILeaveRequestService {
    List<LeaveRequest> selectAllRequests();
    
    LeaveRequest selectRequestById(Long requestId);
    
    int insertLeaveRequest(LeaveRequest leaveRequest);
    
    int updateLeaveRequest(LeaveRequest leaveRequest);
    
    int deleteLeaveRequestById(Long requestId);
    
    List<LeaveRequest> selectPendingRequests(String approver);
}
```

#### 5.2 审批记录服务接口

```java
package com.ruoyi.project.system.leave.service;

import com.ruoyi.project.system.leave.domain.LeaveApproval;
import java.util.List;

public interface ILeaveApprovalService {
    List<LeaveApproval> selectApprovalsByRequestId(Long requestId);
    
    int insertLeaveApproval(LeaveApproval leaveApproval);
}
```

### 6. 控制器(Controller)

        } else {
            leaveRequest.setStatus("已驳回");
        }

        return leaveRequestService.updateLeaveRequest(leaveRequest);
    }
}
```

### 7. 前端页面开发(Vue.js)

#### 7.1 请假申请页面

```html

      approveLeaveRequest({
        requestId: record.requestId,
        approver: this.$store.state.user.name,
        approvalStatus: status,
        comments: '审批意见',
      }).then(() => {
        this.$message.success(`${status}成功`);
        this.loadPendingRequests();
      });
    },
  },
};
</script>
```

### 8. 接口对接

```javascript
import request from '@/utils/request';

// 提交请假申请
export function submitLeaveRequest(data) {
  return request({
    url: '/system/leave',
    method: 'post',
    data,
  });
}

// 获取待审批的申请
export function getPendingRequests(approver) {
  return request({
    url: `/system/leave/pending/${approver}`,
    method: 'get',
  });
}

// 审批请假申请
export function approveLeaveRequest(data) {
  return request({
    url: '/system/leave/approval',
    method: 'post',
    data,
  });
}
```
