这是我的组件,包含userService自动连线.问题是没有初始化,总是为空.用户服务从控制器工作正常.

如何在组件内部自动装配服务？

package com.boro.orange.component;

@Component("modelUtil")
public class ModelUtil {
    @Autowired
    private UserService userService; //null

    static Logger log = Logger.getLogger(ModelUtil.class.getName());

    public ModelMap warp(ModelMap model) {

        Object springUserObject = SecurityContextHolder.getContext().getAuthentication().getPrincipal();
        if (springUserObject == null || !(springUserObject instanceof User)) {
            return model;
        }
        User springUser = (User) springUserObject;
        String userEmailAddress = springUser.getUsername();
        com.boro.orange.entity.User signedInUser = userService.getUserByEmailAddress(userEmailAddress);

        if (signedInUser == null) {
            String errorMsg = "Failed to find user by email address[" + userEmailAddress + "]";
            log.error(errorMsg);
            model.addAttribute("Error", errorMsg);
            // TODO add …

当我点击expandable-icons-cancel时,我想保存form-group div 的子标签.这是结构:

<div class="form-group ">
 <label class="" style="padding-top:10px;"> Long Title</label>
 <span class="value ">
  <div class="expandable">
   <div class="expandable-icons">
    <img class="expandable-icons-cancel" style="display:none;" src="test/cancel.png">
   </div>
  </div>
 </span>
</div>

功能:

jQuery('.expandable-icons-cancel').click(function() {
  var parentDiv = jQuery(this).parents('div.expandable'); //-works, but how can i get upper? 
  // How to get 2 steps upper to form-group?
  // How to get get child label text of form-group and save in var?
 }

我正在尝试使用 htmlunit 制作 java 应用程序以从http://www.jobolizer.com站点获取信息。所以问题是我必须用我的网址填充文本框并单击锚点以提交表单。第一部分效果很好（查找表单并用我的数据填充表单文本框），但我无法使用 getByXPath() 方法找到锚点，锚点没有名称或值。

这是我的代码：

public class JobolizerCrawler {
    private final String jobolizerUrl = "http://www.jobolizer.com";
    WebClient webClient = new WebClient(BrowserVersion.FIREFOX_24);

    public JobolizerCrawler () {
        webClient.getOptions().setJavaScriptEnabled(true);
        webClient.getOptions().setCssEnabled(false);
    }
    public void fillTextBoxWithUrl(String vacancyURL) throws IOException {

        final HtmlPage page = webClient.getPage(jobolizerUrl);
        System.out.println(page.asText());
        final HtmlForm form = page.getFirstByXPath("//form[@action='/phpProxy/getJOBolizerResponse_en.php']");
        final HtmlTextInput input = form.getInputByName("url");
        input.setText(vacancyURL);

        HtmlButton button = (HtmlButton) page.getByXPath("/form[@action='/phpProxy/getJOBolizerResponse_en.php']/a[@id=lightboxlink]").get(0);
        HtmlPage page2 = button.click();


        String page2Text = page2.asText();
        System.out.println(page2Text);
    }
}

我正在尝试向 Bootstrap 添加工具提示，尝试了在互联网上找到的所有解决方案 - 没有任何帮助。这是我的下拉列表（我也在使用 String 和 jstl 标签）：

    <div class="btn-group" style="margin-bottom:5px; width: 100%;">
              <a id="tableNameButton" data-placement="bottom" title="Text" class="my-tooltip my-dropdown tableNameButton btn btn-default btn-block btn-select" data-toggle="dropdown" href="#">Select table <span class="caret"></span></a>
              <form:input class="form-control" id="tableNameFormId" path="tableName" style="visibility: hidden; display: none;" />
              <ul id="tableName" class="dropdown-menu scrollable-menu">
                     <c:forEach items="${databaseTables}" var="databaseTable">
                             <li><a href="#">${databaseTable}</a></li>
                     </c:forEach>
              </ul>
    </div>

在 javascript 上：

$('.my-dropdown').dropdown();
$('.my-dropdown').tooltip();

这东西行不通。希望有人已经解决了这个问题，提前致谢。

我在将ModelMap属性传递给tsp页面时遇到问题.Intelij IDEA识别传递良好的变量,但是当我在tomcat上部署应用程序并加载实际页面时,我只能看到变量名而不是变量值.尝试将一些数据打印到.jsp视图.
