原先不支持自定义业务表单的流程流转，因为这样对很多用户就更加方便，流程还是用现有的流程，但表单可以自己单独设计，满足各种不同的业务需求。 

     1、增加一个接口传入当前设计的流程应用类型

     

 
    /**
     * 获取流程分类详细信息
     * @param code 分类编码
     */
    @GetMapping("/appType/{code}")
    public R<List<WfAppTypeVo>> getInfoByCode(@NotNull(message = "主键不能为空") @PathVariable("code") String code) {
        return R.ok(categoryService.queryInfoByCode(code));
    }

2、相应的mapper.xml文件如下：

 <select id="selectAppTypeVoByCode" resultType="com.ruoyi.workflow.domain.vo.WfAppTypeVo">
       select a.app_type id, c.dict_label name from wf_category a  
         LEFT JOIN sys_dict_data c on a.app_type = c.dict_value
         LEFT JOIN sys_dict_type b on b.dict_type = c.dict_type
       where a.`code` = #{code}
    </select>

3、前端传入相应的流程应用类型

主要的ElementBaseInfo.vue修改如下：

<template>
  <div class="panel-tab__content">
    <el-form size="mini" label-width="90px" @submit.native.prevent>
      <el-form-item label="ID">
        <el-input
          v-model="elementBaseInfo.id"
          :disabled="idEditDisabled || elementBaseInfo.$type === 'bpmn:Process'"
          clearable
          @change="updateBaseInfo('id')"
        />
      </el-form-item>
      <el-form-item label="名称">
        <el-input v-model="elementBaseInfo.name" clearable @change="updateBaseInfo('name')" />
      </el-form-item>
      <!--流程的基础属性-->
      <template v-if="elementBaseInfo.$type === 'bpmn:Process'">
        <el-form-item label="应用类型">
         <el-select v-model="elementBaseInfo.processAppType">
            <el-option
               v-for="item in appType"
               :key="item.id"
               :label="item.name"
               :value="item.id">
             </el-option>
          </el-select>
        </el-form-item>
        <el-form-item label="版本标签">
          <el-input v-model="elementBaseInfo.versionTag" clearable @change="updateBaseInfo('versionTag')" />
        </el-form-item>
        <el-form-item label="可执行">
          <el-switch v-model="elementBaseInfo.isExecutable" active-text="是" inactive-text="否" @change="updateBaseInfo('isExecutable')" />
        </el-form-item>
      </template>
    </el-form>
  </div>
</template>
<script>

import { commonParse } from '../parseElement'

export default {
  name: "ElementBaseInfo",
  props: {
    businessObject: Object,
    appType: {
      type: Array,
      default: () => []
    },
    type: String,
    idEditDisabled: {
      type: Boolean,
      default: true
    }
  },
  data() {
    return {
      elementBaseInfo: {},
    };
  },
  watch: {
    businessObject: {
      immediate: false,
      handler: function(val) {
        if (val) {
          this.$nextTick(() => this.resetBaseInfo());
        }
      }
    }
  },
  methods: {
    resetBaseInfo() {
      this.bpmnElement = window?.bpmnInstances?.bpmnElement || {};
      const tempelement =commonParse(this.bpmnElement);//获取流程分类信息
      this.elementBaseInfo = JSON.parse(JSON.stringify(this.bpmnElement.businessObject));
      this.elementBaseInfo.processAppType = this.appType[0];//显示流程应用类型
    },
    updateBaseInfo(key) {
      const attrObj = Object.create(null);
      attrObj[key] = this.elementBaseInfo[key];
      if (key === "id") {
        window.bpmnInstances.modeling.updateProperties(this.bpmnElement, {
          id: this.elementBaseInfo[key],
          di: { id: `${this.elementBaseInfo[key]}_di` }
        });
      } else {
        window.bpmnInstances.modeling.updateProperties(this.bpmnElement, attrObj);
      }
    }
  },
  beforeDestroy() {
    this.bpmnElement = null;
  }
};
</script>

4、效果如下：
