我正在使用javamail API创建电子邮件并将文件附加到它.

有没有办法使用javamail api发送带附件的电子邮件,而无需在文件系统上物理创建文件.

我只想从应用程序中选择一些数据并将其作为文件附加到我的电子邮件中

我该如何附上:

try {
            // create a message
            MimeMessage msg = new MimeMessage(session);
            msg.setFrom(new InternetAddress(from));
            InternetAddress[] address = {new InternetAddress(to)};
            msg.setRecipients(Message.RecipientType.TO, address);
            msg.setSubject(subject);

            // create and fill the first message part
            MimeBodyPart mbp1 = new MimeBodyPart();
            mbp1.setText(msgText1);

            // create the second message part
            MimeBodyPart mbp2 = new MimeBodyPart();

            // attach the file to the message
            **mbp2.attachFile(filename);**


            // create the Multipart and add its parts to it
            Multipart mp = new MimeMultipart();
            mp.addBodyPart(mbp1);
            mp.addBodyPart(mbp2);

            // add the …

我在我的代码库中的一个类中有一个方法,对于我的生活,我无法进行我的junit测试.基本上,当我请求数据库连接时调用此类,如果返回过时连接,则建立新连接

这是我班上的方法片段(为此目的而修剪)

public class TCSOracleDataSourceWrapper extends OracleDataSource {

private static final int STALE_CONNECTION_EX_CODE = 17143;
private OracleConnectionCacheManager cacheManager;  
private String cacheName;
/** Local log variable **/
private final Log logger = LogFactory.getLog(getClass());


/**
 * Class constructor
 * @throws SQLException
 */
public TCSOracleDataSourceWrapper() throws SQLException {
    super();
}

private static final long serialVersionUID = 1L;

@Override
/**
 * Get a connection but if the connection is stale then refresh all DB connections
 * 
 */
public final Connection getConnection() throws SQLException { …

我只是单元测试和ASP.NET MVC的新手.我一直在尝试使用Steve Sanderson的"Pro ASP.NET MVC框架".书中有这段代码:

public class AdminController : Controller
{
 ...

    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult Edit(Product product, HttpPostedFileBase image)
    {
      ...
       productsRepository.SaveProduct(product);

       TempData["message"] = product.Name + " has been saved.";
       return RedirectToAction("Index");
    }
}

他如此测试:

[Test]
public void Edit_Action_Saves_Product_To_Repository_And_Redirects_To_Index()
{
    // Arrange
    AdminController controller = new AdminController(mockRepos.Object);

    Product newProduct = new Product();

    // Act
    var result = (RedirectToRouteResult)controller.Edit(newProduct, null);

    // Assert: Saved product to repository and redirected
    mockRepos.Verify(x => x.SaveProduct(newProduct));
    Assert.AreEqual("Index", result.RouteValues["action"]);
}

测试通行证.

所以我故意通过添加"productsRepository.DeleteProduct(product);"来破坏代码.在"SaveProduct(product);"之后 如:

            ...
       productsRepository.SaveProduct(product);
       productsRepository.DeleteProduct(product);
            ... …

我想在我的IDEA Web应用程序项目中包含一个使用maven2(pom.xml)的.jar.

如何在不使用maven的项目中添加.jar？

有人可以帮我配置log 4j.我正在使用eclipse,该应用程序是一个gwt应用程序.无论何时,我正在启动网络应用程序,它正在显示

log4j:WARN No appenders could be found for logger (org.apache.jasper.compiler.JspRuntimeContext).
log4j:WARN Please initialize the log4j system properly.

我已将log4j.propeties文件放在gwt应用程序的src中.log4j.propeties文件包含:

# Set root logger level to DEBUG and its only appender to Appender1.
log4j.rootLogger=INFO, Appender1,Appender2

# Appender1 is set to be a ConsoleAppender.
log4j.appender.Appender1=org.apache.log4j.ConsoleAppender
log4j.appender.Appender2=org.apache.log4j.RollingFileAppender
log4j.appender.Appender2.File=sample.log


# Appender2 uses PatternLayout.
log4j.appender.Appender1.layout=org.apache.log4j.PatternLayout
log4j.appender.Appender1.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

log4j.appender.Appender2.layout=org.apache.log4j.PatternLayout
log4j.appender.Appender2.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

有人可以帮忙吗？
