springboot+ueditor1.4.33实现附件上传功能至本地

实现Spring Boot和ueditor1.4.33的附件上传至本地的步骤如下：

1. 添加ueditor1.4.33的jar包依赖，在pom.xml中添加以下代码：

<dependency>
    <groupId>com.baidu.ueditor</groupId>
    <artifactId>ueditor</artifactId>
    <version>1.4.3</version>
</dependency>

2. 配置ueditor，在resources目录下创建config.json文件，添加以下代码：

{
    "imageActionName": "uploadimage",
    "imageFieldName": "upfile",
    "imageMaxSize": 2048000,
    "imageAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"],
    "imageCompressEnable": true,
    "imageCompressBorder": 1600,
    "imageInsertAlign": "none",
    "imageUrlPrefix": "",
    "imagePathFormat": "/ueditor/jsp/upload/image/{yyyy}{mm}{dd}/{time}{rand:6}",
    "scrawlActionName": "uploadscrawl",
    "scrawlFieldName": "upfile",
    "scrawlPathFormat": "/ueditor/jsp/upload/image/{yyyy}{mm}{dd}/{time}{rand:6}",
    "scrawlMaxSize": 2048000,
    "scrawlUrlPrefix": "",
    "scrawlInsertAlign": "none",
    "snapscreenActionName": "uploadimage",
    "snapscreenPathFormat": "/ueditor/jsp/upload/image/{yyyy}{mm}{dd}/{time}{rand:6}",
    "snapscreenUrlPrefix": "",
    "snapscreenInsertAlign": "none",
    "catcherLocalDomain": ["127.0.0.1", "localhost", "img.baidu.com"],
    "catcherActionName": "catchimage",
    "catcherFieldName": "source",
    "catcherPathFormat": "/ueditor/jsp/upload/image/{yyyy}{mm}{dd}/{time}{rand:6}",
    "catcherUrlPrefix": "",
    "catcherMaxSize": 2048000,
    "catcherAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"],
    "videoActionName": "uploadvideo",
    "videoFieldName": "upfile",
    "videoPathFormat": "/ueditor/jsp/upload/video/{yyyy}{mm}{dd}/{time}{rand:6}",
    "videoUrlPrefix": "",
    "videoMaxSize": 102400000,
    "videoAllowFiles": [
        ".flv", ".swf", ".mkv", ".avi", ".rm", ".rmvb", ".mpeg", ".mpg",
        ".ogg", ".ogv", ".mov", ".wmv", ".mp4", ".webm", ".mp3", ".wav", ".mid"
    ],
    "fileActionName": "uploadfile",
    "fileFieldName": "upfile",
    "filePathFormat": "/ueditor/jsp/upload/file/{yyyy}{mm}{dd}/{time}{rand:6}",
    "fileUrlPrefix": "",
    "fileMaxSize": 51200000,
    "fileAllowFiles": [
        ".png", ".jpg", ".jpeg", ".gif", ".bmp",
        ".flv", ".swf", ".mkv", ".avi", ".rm", ".rmvb", ".mpeg", ".mpg",
        ".ogg", ".ogv", ".mov", ".wmv", ".mp4", ".webm", ".mp3", ".wav", ".mid",
        ".rar", ".zip", ".tar", ".gz", ".7z", ".bz2", ".cab", ".iso",
        ".doc", ".docx", ".xls", ".xlsx", ".ppt", ".pptx", ".pdf", ".txt", ".md", ".xml"
    ],
    "imageManagerActionName": "listimage",
    "imageManagerListPath": "/ueditor/jsp/upload/image/",
    "imageManagerListSize": 20,
    "imageManagerUrlPrefix": "",
    "imageManagerInsertAlign": "none",
    "imageManagerAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"],
    "fileManagerActionName": "listfile",
    "fileManagerListPath": "/ueditor/jsp/upload/file/",
    "fileManagerUrlPrefix": "",
    "fileManagerListSize": 20,
    "fileManagerAllowFiles": [
        ".png", ".jpg", ".jpeg", ".gif", ".bmp",
        ".flv", ".swf", ".mkv", ".avi", ".rm", ".rmvb", ".mpeg", ".mpg",
        ".ogg", ".ogv", ".mov", ".wmv", ".mp4", ".webm", ".mp3", ".wav", ".mid",
        ".rar", ".zip", ".tar", ".gz", ".7z", ".bz2", ".cab", ".iso",
        ".doc", ".docx", ".xls", ".xlsx", ".ppt", ".pptx", ".pdf", ".txt", ".md", ".xml"
    ]
}

3. 在Controller中添加上传附件的方法，例如：

@Controller
@RequestMapping("/file")
public class FileController {

    @PostMapping("/upload")
    @ResponseBody
    public Map<String, Object> uploadFile(HttpServletRequest request, HttpServletResponse response) {
        // 获取配置文件路径
        String rootPath = request.getSession().getServletContext().getRealPath("/");
        String configPath = rootPath + "config.json";

        // 创建配置对象
        ConfigManager configManager = ConfigManager.getInstance(rootPath, "http://localhost:8080/ueditor/jsp");
        try {
            // 初始化配置
            configManager.initEnv(configPath);
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }

        // 创建上传对象
        UEditorUploader uploader = new BinaryUploader(configManager, request, response);
        // 执行上传
        Map<String, Object> result = uploader.doExec();
        return result;
    }
}

4. 在前端页面中使用ueditor上传附件，例如：

<!-- 加载ueditor -->
<script type="text/javascript" src="/ueditor/ueditor.config.js"></script>
<script type="text/javascript" src="/ueditor/ueditor.all.js"></script>

<!-- 创建ueditor实例 -->
<script type="text/javascript">
    var ue = UE.getEditor('editor');
</script>

<!-- 创建上传按钮 -->
<div class="btn btn-primary" onclick="chooseFile()">上传文件</div>

<!-- 上传文件 -->
<script type="text/javascript">
    function chooseFile() {
        // 创建表单对象
        var formData = new FormData();
        // 获取文件对象
        var file = document.getElementById("file").files[0];
        // 添加文件到表单中
        formData.append("upfile", file);

        // 发送ajax请求
        $.ajax({
            url: "/file/upload",
            type: "POST",
            data: formData,
            cache: false,
            contentType: false,
            processData: false,
            success: function (result) {
                if (result.state === "SUCCESS") {
                    // 上传成功，将附件地址添加到ueditor中
                    ue.execCommand('insertHtml', '<a href="' + result.url + '">' + result.title + '</a>');
                } else {
                    alert("上传失败");
                }
            }
        });
    }
</script>

以上就是实现Spring Boot和ueditor1.4.33的附件上传至本地的完整步骤。
