如将10.0.1.155的/u01/attachments 目录挂载到10.0.1.156对应的/u01/attachments 目录下。
使用以下命令：
mount 10.0.1.155:/u01/attachments /u01/attachments

一、在项目根目录下安装
npm install --save js-base64
npm install --save js-md5

二、在项目文件中引入
import md5 from 'js-md5';

let Base64 = require('js-base64').Base64;

三、在项目文件中使用
base64

Base64.encode('heckjj.com');  // aGVja2pqLmNvbQ==
Base64.encode( '大将军');    // 5aSn5bCG5Yab+
Base64.encodeURI('大将军'); // 5aSn5bCG5Yab-

Base64.decode(aGVja2pqLmNvbQ==');  // heckjj.com
Base64.decode('5aSn5bCG5Yab+');  // 大将军
// note .decodeURI() is unnecessary since it accepts both flavors
Base64.decode('5aSn5bCG5Yab-');  // 大将军

md5

md5(''); // d41d8cd98f00b204e9800998ecf8427e
md5('The quick brown fox jumps over the lazy dog'); // 9e107d9d372bb6826bd81d3542a419d6
md5('The quick brown fox jumps over the lazy dog.'); // e4d909c290d0fb1ca068ffaddf22cbd0

// It also supports UTF-8 encoding
md5('中文'); // a7bac2239fcdcb3a067903d8077c4a07

// It also supports byte `Array`, `Uint8Array`, `ArrayBuffer`
md5([]); // d41d8cd98f00b204e9800998ecf8427e
md5(new Uint8Array([])); // d41d8cd98f00b204e9800998ecf8427e

// Different output
md5(''); // d41d8cd98f00b204e9800998ecf8427e
md5.hex(''); // d41d8cd98f00b204e9800998ecf8427e
md5.array(''); // [212, 29, 140, 217, 143, 0, 178, 4, 233, 128, 9, 152, 236, 248, 66, 126]
md5.digest(''); // [212, 29, 140, 217, 143, 0, 178, 4, 233, 128, 9, 152, 236, 248, 66, 126]
md5.arrayBuffer(''); // ArrayBuffer
md5.buffer(''); // ArrayBuffer, deprecated, This maybe confuse with Buffer in node.js. Please use arrayBuffer instead.

Element UI Upload 上传文件上传文件一次 ，不论是上传成功之后修改文件再上传还是上传失败重新上传，再次点击上传均无反应。
方法一：利用 :on-success
ref=‘upload’
:on-success=“handleSuccess”

注意： ref='upload 一定要加上ref 不然不起作用

                <el-upload
                        class="upload-demo"
                        action=""
                        :limit="1"
                        :show-file-list="false"
                        :http-request="uploadLogo"
                        ref='upload'
                        :on-success="handleSuccess"
                >
                    <el-button style="width: 150px; height: 35px;line-height: 0;margin-left: 20px" size="medium"
                               type="primary">
                        {{$t('StaffManage.bulkImport')}}
                    </el-button>
                </el-upload>

        handleSuccess(res, file) {
            this.$refs.upload.clearFiles(); //上传成功之后清除历史记录
            // this.tableReload()
        },

方法二：利用if el-upload让移除文档流
                <el-upload
                        v-if="!form.contractFileUrl"
                        class="upload-demo"
                        action=""
                        :limit="1"
                        :show-file-list="false"
                        :http-request="uploadLogo"
                >
                    <el-button size="medium" type="primary">{{$t('AttendanceInformation.ClickUpload')}}</el-button>
                </el-upload>

            uploadLogo(param) {
                let _this = this
                _this.form.contractFileUrl = '1'
                let formData = new FormData();
                formData.append("file", param.file);
                _this.$send.post({url: '/contract/upload', data: formData}, res => {
                    if (res.code === 10000) {
                        _this.isdisabled = true
                        _this.form.contractFileUrl = res.data.url
                        _this.form.contractFileId = res.data.id
                    } else {
                        _this.form.contractFileUrl = null
                        _this.form.contractFileId = null
                        _this.$msg.error(res.message)
                    }

                })
            },

sql执行正常的，但是放到mybatisPlus中执行错误报: Failed to process, please exclude the tableName or statementId.

大概率是存在特殊字符使mybatis解析异常
1.在mapper.java中的方法上添加@SqlParser(filter=true)注解


2.如果sql中有注释，删掉注释
