基于jeesite的cms系统（五）：wangEditor富文本编辑器

一、关于wangEditor：

二、创建wangEditor

editor创建十分简单只需要引入js文件（这里注意要加上版本号，具体原因不详），进行一些配置即可

因为这里使用的是Beetl模板表单，所以使用textarea来接收wangEditor的值

var $textarea = $('#textarea')
editor.customConfig.onchange = function (html) {
    // 监控变化，同步更新到 textarea
    $textarea.val(html)
}

<% layout('/layouts/default.html', {title: '发布文章', libs: ['validate','fileupload','ueditor','dataGrid']}){ %>
<div class="main-content">
    <div class="box box-main">
        <div class="box-header with-border">
            <div class="box-title">
                <i class="fa fa-list-alt"></i> ${testData.isNewRecord ? '编辑文章' : '编辑文章'}
            </div>
            <div class="box-tools pull-right">
                <button type="button" class="btn btn-box-tool" data-widget="collapse"><i class="fa fa-minus"></i></button>

<% } %>
<script type="text/javascript" src="/static/common/wangEditor/wangEditor.js?V4.1-01161701"></script>
<script type="text/javascript">
    // 初始化wangEditor
    var E = window.wangEditor
    var editor = new E('#editor')

    // 自定义菜单配置
    // editor.customConfig.menus = [
    // 'bold',  // 粗体

    $(".col-sm-2").css("width","11.66666667%");

<script>
    $("#inputForm").validate({

                js.closeCurrentTabPage(function(contentWindow){
                    contentWindow.page();
                });

        }, "json");
            // js.showMessage('文章发布成功');
        }
    });
</script>

如果不用beetl表单，只需要这样

var comments = editor.txt.html();

来接收数据

二、文件上传类

wangEditor接受Map返回集

package com.jeesite.modules.cms.web;

import java.io.File;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;
import java.util.UUID;
import javax.servlet.http.HttpServletRequest;

import com.jeesite.modules.cms.utils.PathUtil;
import org.springframework.stereotype.Controller;
import org.springframework.util.FileCopyUtils;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.multipart.MultipartFile;

/**
 * @author zombie
 */
@Controller
public class UploadController {

    @RequestMapping("/upload")
    @ResponseBody
    public Map<String, String> upload(@RequestParam(value="myFileName") MultipartFile file, HttpServletRequest request) {
        Map<String, String> map = new HashMap<String, String>();
        String separator = System.getProperty("file.separator");

        // 用于前端图片显示的路径  http://localhost:8080/upload/
        String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + request.getContextPath()
                + separator +"upload" + separator;
        // 用于保存图片至项目的路径 D:\_eclipsework\.metadata\.plugins\org.eclipse.wst.server.core\tmp2\wtpwebapps\JYSystem\ upload\
        // 或者 String uploadDir = request.getSession().getServletContext().getRealPath("upload") + separator;
        String uploadDir = PathUtil.getProjectPath() + separator +"upload" + separator;

        byte[] bytes = null;
        try {

            bytes = file.getBytes();
            File dirPath = new File(uploadDir);
            if (!dirPath.exists()) {
                if (!dirPath.mkdirs()) {
                }
            }

            /**
             * 构建新的图片名称
             */
            String fileName = file.getOriginalFilename();
            int index = fileName.lastIndexOf(".");
            String extName = index > -1 ? fileName.substring(index) : ""; // .jpg
            String uuid = UUID.randomUUID().toString().trim().replaceAll("-", "");
            String newFileName = uuid + extName;

            /**
             * 保存图片至项目
             */
            String filePath = uploadDir + newFileName;
            File descFile = new File(filePath);
            FileCopyUtils.copy(bytes, descFile);

            map.put("data", basePath + newFileName);
        } catch (IOException e) {
            e.printStackTrace();
        }

        return map;
    }

}

五、修改视图渲染路径

开始在这里路径总是报错，一度以为是/cms的问题，结果发现是把返回的postArticle.html拼写错了

package com.jeesite.modules.cms.web;

import com.jeesite.common.web.BaseController;
import com.jeesite.modules.test.entity.TestData;
import com.jeesite.modules.test.service.TestDataService;
import org.apache.shiro.authz.annotation.RequiresPermissions;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping(value = "${adminPath}/cms")
public class CmsController extends BaseController {

    @Autowired
    private TestDataService testDataService;

    /**
     * 获取数据
     */
    @ModelAttribute
    public TestData get(String id, boolean isNewRecord) {
        return testDataService.get(id, isNewRecord);
    }

    /**
     * Form
     */
    @RequiresPermissions("test:testData:view")
    @RequestMapping(value = "form/postArticle")
    public String form(TestData testData, Model model) {
        return "templates/postArticle";
    }
}
