我有一个junit测试方法,它将CommonsMultipartFile对象作为参数.

我正在尝试创建一个FileItem对象,以便将其传递给构造函数,

CommonsMultipartFile(org.apache.commons.fileupload.FileItem fileItem)

为此,我尝试使用DiskFileItem构造函数创建FileItem对象,

DiskFileItem(java.lang.String fieldName, java.lang.String contentType, boolean isFormField, java.lang.String fileName, int sizeThreshold, java.io.File repository)

但我不知道如何传递任何这些参数.

我所有这些都在Spring 3 MVC控制器中工作,但是为了进行junit测试,我需要传递一个方法两个对象.一个是UploadItem对象,如下所示,

import org.springframework.web.multipart.commons.CommonsMultipartFile;

public class UploadItem {
 private String fileName;
 private String filePath;
 private CommonsMultipartFile fileData;

 public String getFileName() {
  return fileName;
 }

 public void setFileName(String fileName) {
  this.fileName = fileName;
 }

 public String getFilePath() {
  return filePath;
 }

 public void setFilePath(String filePath) {
  this.filePath = filePath;
 }

 public CommonsMultipartFile getFileData() {
  return fileData;
 }

 public void setFileData(CommonsMultipartFile fileData) { …

所以我有一个主JSP索引页面"index.jsp",它有几个包含.就像是,

<%@ include file="/WEB-INF/views/includes/jstl/include.jsp" %>
<%@ include file="/WEB-INF/views/includes/licenses/license.jsp" %>
<%@ include file="/WEB-INF/views/includes/generalHtml/header.jsp" %>
<%@ include file="/WEB-INF/views/includes/navigation/navbar.jsp" %>
<%@ include file="/WEB-INF/views/includes/generalHtml/footer.jsp" %>

"include.jsp"包含字符串"String basePath = request.getContextPath();".

"navbar.jsp"使用"basePath",但Eclipse在"navbar.jsp"的任何一行上放置一个红色X,该行使用"basePath",消息"basePath无法解析".

我的webapp工作正常,但想知道可能导致这种情况的原因,或者它是否可以解决？或者也许有办法让Eclipse忽略这个？我只想让假阳性的红色X消失.我想Eclipse并不理解"navbar.jsp"从"include.jsp"获取"basePath",因为它与"index.jsp"一起编译.

我正在开发一个最近引入lambda表达式的项目.一个例子是这样的.

public class ExampleItemWriter implements ItemWriter<MyItem> {
    public void write(List<? extends MyItem> list) throws RepositoryException {
        list.stream().forEach((item)->{
            if (item == null) {
            }
        });
    }
}

我不相信里面的细节forEach()与问题有关,但如果他们是我可以发布.在整个代码中还有一些其他类似的表达式抛出相同的异常.

我有一个配置了 SSO 的 Argo Workflows 实例。当我单击工作流程链接时，如果我未登录，它会将我带到登录页面，这迫使我单击“登录”按钮将我重定向到我的 SSO 提供商，然后在成功时将我重定向到工作流程。

有谁知道是否可以配置 SSO 身份验证，以便跳过登录页面并将用户直接重定向到 SSO 登录页面？我一直在浏览文档和源代码，但没有运气，我想在放弃之前我会在这里问。

首先,我有一个Spring 3.0控制器,其方法类似于以下方法.

我正在向视图传递一个名为"message"的对象,如果已经通过"doStuff"方法设置,则希望通过视图打印该消息.

@RequestMapping("/index")
public ModelAndView doStuff() {
    ModelAndView mav = new ModelAndView();
    Map<String, String> message = new HashMap<String, String>();
    message.put("message", "Hello World");
    mav.setViewName("pages/myView");
    mav.addObject("message", message);
    return mav;
}

该视图类似于以下内容,

<%@ page session="false"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core_rt" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt" %>
<html>
<head>
<title>Test</title>
</head>
<body>
<c:if test="${message.message} != null">
    <div class="msg">test1: ${message.message}</div>
</c:if>
<c:if test="${message.message} != ''">
    <div class="msg">test2: ${message.message}</div>
</c:if>
<c:if test="${message.message}">
    <div class="msg">test3: ${message.message}</div>
</c:if>
<c:if test="not empty ${message.message}">
    <div class="msg">test4: ${message.message}</div>
</c:if>
<div class="msg">test5: …

我有两个实体,Document并BodyElement试图用Hibernate 4.2来坚持它们.mtdt_t填入正确的,但外键docid的mtdt_body_t表NULL.

我看到hibernate试图插入没有docid值.insert into mtdt_body_t values ( )

@Entity
@Table(name = "mtdt_t")
public class Document implements Serializable {

    @Id  
    @Column(name = "docid", unique = true, nullable = false)
    private String docid;

    @OneToOne(cascade = CascadeType.ALL, orphanRemoval = true, fetch = FetchType.EAGER)
    @OrderColumn
    @JoinColumn(name = "docid", nullable = false)
    private BodyElement bodyElement;

    public String getDocid() {
        return docid;
    }

    public void setDocid(String docid) {
        this.docid = docid; …

我试图创建使用Spring的批处理作业ListItemReader<String>,ItemProcessor<String, String>和ItemWriter<String>.

XML如下所示,

<job id="sourceJob" xmlns="http://www.springframework.org/schema/batch">
    <step id="step1" next="step2">
        <tasklet>
            <chunk reader="svnSourceItemReader" 
                processor="metadataItemProcessor" 
                writer="metadataItemWriter" 
                commit-interval="1" />
        </tasklet>
    </step>
    <step id="step2">
        <tasklet ref="lastRevisionLoggerTasklet"></tasklet>
    </step>
</job>

<bean id="svnSourceItemReader" 
        class="com.example.repository.batch.SvnSourceItemReader" 
        scope="prototype">
    <constructor-arg index="0">
        <list>
            <value>doc1.xkbml</value>
            <value>doc2.xkbml</value>
            <value>doc3.xkbml</value>
        </list>
    </constructor-arg>
</bean>

<bean id="metadataItemProcessor" 
        class="com.example.repository.batch.MetadataItemProcessor" 
        scope="prototype" />

<bean id="metadataItemWriter" 
        class="com.example.repository.batch.MetadataItemWriter" 
        scope="prototype" />

读者,处理者和作家都是香草,

public class SvnSourceItemReader extends ListItemReader<String> {

    public SvnSourceItemReader(List<String> list) {
        super(list);
        System.out.println("Reading data list " + list);
    }

    @Override
    public String read() {
        String out = …

我有一个包含三列的MySQL(5.1.49)表.

mysql> create table testme(id int auto_increment, id2 int not null, somedate datetime, primary key(id));

在我的情况下,id2不是唯一的,但我想返回具有不同id2值和max somedate的行.

这是一些示例数据.

mysql> insert into testme values (1, 5, '2012-01-02 01:01:01'),(2, 5, '2012-02-02 02:02:02'),(3, 7, '2010-01-10 11:01:33');

这个问题几乎可以回答我的问题,但是使用额外的id字段,返回的id和id2不匹配.对于id2 = 5,它返回id = 1而不是id = 2.

mysql> select id, id2, max(somedate) from testme group by id2;
+----+-----+---------------------+
| id | id2 | max(somedate)       |
+----+-----+---------------------+
|  1 …

我的目标是获取XML字符串并使用XMLBeans XmlObject解析它并添加一些子节点.

这是一个示例文档(xmlString),

<?xml version="1.0"?>
<rootNode>
 <person>
  <emailAddress>joefoo@example.com</emailAddress>
 </person>
</rootNode>

这是添加一些节点后我想要XML文档的方式,

<?xml version="1.0"?>
<rootNode>
 <person>
  <emailAddress>joefoo@example.com</emailAddress>
  <phoneNumbers>
   <home>555-555-5555</home>
   <work>555-555-5555</work>
  <phoneNumbers>
 </person>
</rootNode>

基本上,只需添加<phoneNumbers/>两个子节点的节点<home/>和<work/>.

就我而言,

XmlObject xml = XmlObject.Factory.parse(xmlString);

谢谢
