今天讲一下wf_demo表单的一些修改
1、demo的实现类修改如下：
主要是增加一个服务名称，后面要用到，同时继承于WfCallBackServiceI，以便进行调用。
@Service("wfDemoService")
public class WfDemoServiceImpl extends ServiceImpl<WfDemoMapper, WfDemo> implements IWfDemoService, WfCallBackServiceI
package com.ruoyi.workflow.service.impl;
import cn.hutool.core.bean.BeanUtil;
import com.ruoyi.common.utils.StringUtils;
import com.ruoyi.common.core.page.TableDataInfo;
import com.ruoyi.common.core.domain.PageQuery;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.baomidou.mybatisplus.core.conditions.query.LambdaQueryWrapper;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.core.toolkit.Wrappers;
import lombok.RequiredArgsConstructor;
import org.springframework.stereotype.Service;
import com.ruoyi.workflow.domain.bo.WfDemoBo;
import com.ruoyi.workflow.domain.vo.WfDemoVo;
import com.ruoyi.workflow.domain.WfDemo;
import com.ruoyi.workflow.domain.WfMyBusiness;
import com.ruoyi.workflow.mapper.WfDemoMapper;
import com.ruoyi.workflow.service.IWfDemoService;
import com.ruoyi.workflow.service.WfCallBackServiceI;
import java.util.List;
import java.util.Map;
import java.util.Collection;
/**
* DEMOService业务层处理
*
* @author nbacheng
* @date 2023-10-12
*/
@RequiredArgsConstructor
@Service("wfDemoService")
public class WfDemoServiceImpl extends ServiceImpl<WfDemoMapper, WfDemo> implements IWfDemoService, WfCallBackServiceI {
private final WfDemoMapper baseMapper;
/**
* 查询DEMO
*/
@Override
public WfDemoVo queryById(Long demoId){
return baseMapper.selectVoById(demoId);
}
/**
* 查询DEMO列表
*/
@Override
public TableDataInfo<WfDemoVo> queryPageList(WfDemoBo bo, PageQuery pageQuery) {
LambdaQueryWrapper<WfDemo> lqw = buildQueryWrapper(bo);
Page<WfDemoVo> result = baseMapper.selectVoPage(pageQuery.build(), lqw);
return TableDataInfo.build(result);
}
/**
* 查询DEMO列表
*/
@Override
public List<WfDemoVo> queryList(WfDemoBo bo) {
LambdaQueryWrapper<WfDemo> lqw = buildQueryWrapper(bo);
return baseMapper.selectVoList(lqw);
}
private LambdaQueryWrapper<WfDemo> buildQueryWrapper(WfDemoBo bo) {
Map<String, Object> params = bo.getParams();
LambdaQueryWrapper<WfDemo> lqw = Wrappers.lambdaQuery();
lqw.like(StringUtils.isNotBlank(bo.getUserName()), WfDemo::getUserName, bo.getUserName());
lqw.like(StringUtils.isNotBlank(bo.getNickName()), WfDemo::getNickName, bo.getNickName());
lqw.eq(StringUtils.isNotBlank(bo.getEmail()), WfDemo::getEmail, bo.getEmail());
lqw.eq(StringUtils.isNotBlank(bo.getAvatar()), WfDemo::getAvatar, bo.getAvatar());
lqw.eq(StringUtils.isNotBlank(bo.getStatus()), WfDemo::getStatus, bo.getStatus());
return lqw;
}
/**
* 新增DEMO
*/
@Override
public Boolean insertByBo(WfDemoBo bo) {
WfDemo add = BeanUtil.toBean(bo, WfDemo.class);
validEntityBeforeSave(add);
boolean flag = baseMapper.insert(add) > 0;
if (flag) {
bo.setDemoId(add.getDemoId());
}
return flag;
}
/**
* 修改DEMO
*/
@Override
public Boolean updateByBo(WfDemoBo bo) {
WfDemo update = BeanUtil.toBean(bo, WfDemo.class);
validEntityBeforeSave(update);
return baseMapper.updateById(update) > 0;
}
/**
* 保存前的数据校验
*/
private void validEntityBeforeSave(WfDemo entity){
//TODO 做一些数据校验,如唯一约束
}
/**
* 批量删除DEMO
*/
@Override
public Boolean deleteWithValidByIds(Collection<Long> ids, Boolean isValid) {
if(isValid){
//TODO 做一些业务上的校验,判断是否需要校验
}
return baseMapper.deleteBatchIds(ids) > 0;
}
@Override
public Page<WfDemoBo> myPage(Page<WfDemoBo> page, QueryWrapper<WfDemoBo> queryWrapper) {
return baseMapper.myPage(page, queryWrapper);
}
@Override
public void afterFlowHandle(WfMyBusiness business) {
//流程操作后做些什么
business.getTaskNameId();//接下来审批的节点
business.getValues();//前端传进来的参数
business.getActStatus();//流程状态 ActStatus.java
//....其他
}
@Override
public Object getBusinessDataById(String dataId) {
return this.getById(dataId);
}
@Override
public Map<String, Object> flowValuesOfTask(String taskNameId, Map<String, Object> values) {
// TODO Auto-generated method stub
return null;
}
@Override
public List<String> flowCandidateUsernamesOfTask(String taskNameId, Map<String, Object> values) {
// TODO Auto-generated method stub
return null;
}
}2、增加一个列表查询的sql，主要是动态增加流程相关内容
<select id="myPage" resultType="com.ruoyi.workflow.domain.bo.WfDemoBo">
select t.*,b.process_definition_key,
b.process_definition_id,
b.process_instance_id,
b.title,
b.data_id,
b.service_impl_name,
b.proposer,
b.act_status,
b.todo_users,
b.done_users,
b.priority,
b.task_id,
b.task_name_id,
b.task_name,
b.deploy_id
from wf_demo t left join wf_my_business b on b.data_id = t.demo_id
${ew.customSqlSegment}
</select>3、demo列表接口进行修改
/**
* 查询DEMO列表
*/
@SaCheckPermission("workflow:demo:list")
@GetMapping("/list")
public TableDataInfo<WfDemoBo> list(WfDemoBo bo, PageQuery pageQuery, HttpServletRequest req) {
//by nbacheng for java.sql.SQLSyntaxErrorException: ORA-00918: 未明确定义列
Map<String, String[]> ParameterMap = new HashMap<String, String[]>(req.getParameterMap());
String[] column = new String[]{""};
if(ParameterMap!=null&& ParameterMap.containsKey("column")) {
column[0] = ParameterMap.get("column")[0];
column[0] = "t."+ column[0];
ParameterMap.replace("column", column);
log.info("修改的排序规则>>列:" + ParameterMap.get("column")[0]);
}
QueryWrapper<WfDemoBo> queryWrapper = QueryGenerator.initQueryWrapper(bo, ParameterMap);
Page<WfDemoBo> page = new Page<WfDemoBo>(pageQuery.getPageNum(), pageQuery.getPageSize());
Page<WfDemoBo> result = iWfDemoService.myPage(page, queryWrapper);
return TableDataInfo.build(result);
}4、增加前端显示demo内容的页面
<template>
<div class="app-container">
<!-- 显示DEMO数据 -->
<el-form ref="form" :model="form" label-width="80px" :disabled="disabled">
<el-form-item label="用户账号" prop="userName">
<el-input v-model="form.userName" placeholder="" />
</el-form-item>
<el-form-item label="用户昵称" prop="nickName">
<el-input v-model="form.nickName" placeholder="" />
</el-form-item>
<el-form-item label="用户邮箱" prop="email">

</el-form-item>
<el-form-item label="头像地址" prop="avatar">
<el-input v-model="form.avatar" placeholder="" />
</el-form-item>
<el-form-item label="备注" prop="remark">
<el-input v-model="form.remark" type="textarea" placeholder="" />
</el-form-item>
</el-form>
<!--<div slot="footer" class="dialog-footer">
<el-button :loading="buttonLoading" type="primary" @click="submitForm">确 定</el-button>
<el-button @click="cancel">取 消</el-button>
</div> -->
</div>
</template>
<script>
import {getDemo, delDemo, addDemo, updateDemo } from "@/api/workflow/demo";
export default {
name: "wfDemo",
components: {
},
props: {
//表单禁用
disabled: {
type: Boolean,
default: false,
required: false
},
/*流程自定义表单数据*/
customFormData:{
type:Object,
default:()=>{return {}},
required:false
},
},
data() {
return {
// 按钮loading
buttonLoading: false,
// 弹出层标题
title: "",
// 是否显示弹出层
open: true,
// 表单参数
form: {},
}
},
created() {
//流程调用自定义表单的传入参数
if(this.customFormData != null) {
console.log("this.customFormData=",this.customFormData);
this.form = this.customFormData;
}
//this.handleView(this.form);
},
methods: {
// 取消按钮
cancel() {
this.open = false;
this.reset();
},
// 表单重置
reset() {
this.form = {
demoId: undefined,
userName: undefined,
nickName: undefined,
email: undefined,
avatar: undefined,
status: undefined,
delFlag: undefined,
createBy: undefined,
createTime: undefined,
updateBy: undefined,
updateTime: undefined,
remark: undefined
};
this.resetForm("form");
},
/** 新增按钮操作 */
handleAdd() {
this.reset();
this.open = true;
this.title = "添加DEMO";
},
/** 查看按钮操作 */
handleView(row) {
this.loading = true;
this.reset();
const demoId = row.demoId || this.ids
getDemo(demoId).then(response => {
this.loading = false;
this.form = response.data;
this.open = true;
this.title = "DEMO详情";
});
},
/** 修改按钮操作 */
handleUpdate(row) {
this.loading = true;
this.reset();
const demoId = row.demoId || this.ids
getDemo(demoId).then(response => {
this.loading = false;
this.form = response.data;
this.open = true;
this.title = "修改DEMO";
});
},
/** 提交按钮 */
submitForm() {
this.$refs["form"].validate(valid => {
if (valid) {
this.buttonLoading = true;
if (this.form.demoId != null) {
updateDemo(this.form).then(response => {
this.$modal.msgSuccess("修改成功");
this.open = false;
this.getList();
}).finally(() => {
this.buttonLoading = false;
});
} else {
addDemo(this.form).then(response => {
this.$modal.msgSuccess("新增成功");
this.open = false;
this.getList();
}).finally(() => {
this.buttonLoading = false;
});
}
}
});
},
}
}
</script>
<style>
</style>5、demo页面增加流程相关的按钮与组件方法
<template>
<div class="app-container">
