小编Thu*_*tne的帖子

我是JavaFx的新手.在我的JavaFX应用程序中,我设置了onAction属性,当我使用鼠标按下按钮时,它工作正常.即使用户按下Enter按钮,我也要发射相同的内容.我知道我可以使用偶数处理程序来做到这一点.但是当我阅读onAction JavaDoc时,它说这个事件会被按键发生.

楼盘简介:

按钮的动作,每当触发按钮时都会调用该动作.这可能是由于用户使用鼠标单击按钮,或通过触摸事件或按键,或者开发人员以编程方式调用fire()方法.

但是当我按下Enter键时没有任何反应.这是文档中的错误吗？如果不在按钮上添加alistener,还有其他方法可以实现吗？

PS

在评论后我用空格键检查然后它被解雇了.但我想将其设置为Enter键.我有很多按钮.我试过button.setDefaultButton(true);但它没有被解雇.我认为这是因为有多个按钮.如果我只将它设置为一个按钮,它可以正常工作.如何设置多个按钮？

我正在尝试将gSoap2.8与VS2010 C++项目一起使用,我宣布了一个预构建事件

wsdl2h.exe -o test.h "test.wsdl"

然后它说

error C1083: Cannot open type library file:<path>\stlvector.h: Error loading type library/DLL.  <path>\test.h

所以我用-s来摆脱如下

wsdl2h.exe -s -o .\test.h "test.wsdl"

但后来它说

error : #import: Cannot open file "soap12.h" for reading

我怎么能摆脱这个？

我创建了一个 E2E 测试项目，最初，所有 java 类都在“src/test/java”中，但现在我想将所有不包含测试的文件移动到“src/main/java”文件夹中，问题是在我这样做之后：
我无法将包从“src/test/java”导入到“src/main/java”（但可以做相反的事情）。就像导入的包根本不存在一样。

清理了项目并尝试通过 IDE 和 Maven 运行，但它不会改变结果。

我究竟做错了什么？

我下载了最新版本的ANTLR - 4.2.2(antlr-4.2.2-complete.jar)当我用它来为语法文件Java.g4生成解析器时,它会给我打印一些警告:"Java.g4:525:16: rule'expression'在无法识别的位置包含'assoc'终端选项"

文件已生成但未编译

以前的版本工作正常.

怎么了？

我在用 Java 签名电子邮件时遇到了一些问题。

我相信我的代码很好，但是当我在收件箱中收到电子邮件时，它说无法验证签名。

这里的代码 - 非常简单：

  boolean isAlias = false;

        // Add BouncyCastle content handlers to command map
        MailcapCommandMap mailcap = (MailcapCommandMap) CommandMap.getDefaultCommandMap();

        mailcap.addMailcap("application/pkcs7-signature;; x-java-content-handler=org.bouncycastle.superman.mail.smime.handlers.pkcs7_signature");
        mailcap.addMailcap("application/pkcs7-mime;; x-java-content-handler=org.bouncycastle.superman.mail.smime.handlers.pkcs7_mime");
        mailcap.addMailcap("application/x-pkcs7-signature;; x-java-content-handler=org.bouncycastle.superman.mail.smime.handlers.x_pkcs7_signature");
        mailcap.addMailcap("application/x-pkcs7-mime;; x-java-content-handler=org.bouncycastle.superman.mail.smime.handlers.x_pkcs7_mime");
        mailcap.addMailcap("multipart/signed;; x-java-content-handler=org.bouncycastle.superman.mail.smime.handlers.multipart_signed");

        CommandMap.setDefaultCommandMap(mailcap);

        Security.addProvider(new BouncyCastleProvider());

        KeyStore keyStore = KeyStore.getInstance("JKS");

        InputStream ins = SigningEmail.class.getResourceAsStream("/keystore.jks");

        // Provide location of Java Keystore and password for access
        keyStore.load(ins,"changeit".toCharArray());

        // Find the first legit alias in the keystore and use it
        Enumeration<String> es = keyStore.aliases();
        String alias = "";
        while (es.hasMoreElements()) {
            alias …

由于intsafe.h和stdint.h两者都定义了INT8_MIN。因此，VS2010 会生成一条警告：

    1>C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\stdint.h(72): warning C4005: 'INT8_MIN' : macro redefinition
1>          C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\include\intsafe.h(144) : see previous definition of 'INT8_MIN'

有没有办法在 VS2010 中修复该警告。

我们目前正在使用spring 3.2.9.我们正在考虑将其升级到更新版本.当我检查文档时,它说明了这一点

与4.0 M1一起,我们发布了Spring Framework 3.2.3,其中包含针对最近报告的问题的修复,但也提供了OpenJDK 8运行时支持.对于针对JDK 7(使用-target 1.7)或更早版本编译的应用程序,Spring Framework 3.2.x将支持在JDK 8运行时上进行部署.

这是否意味着我无法在Java 8上编译？
如果我想用Java 8编译,我应该使用Spring 4.0.x版吗？

list.getSelectionModel().select(game_ptr);
list.scrollTo(game_ptr);

运行此代码时,我收到以下警告:

com.sun.javafx.scene.control.skin.VirtualFlow addTrailingCells
INFO: index exceeds maxCellCount. Check size calculations for class com.sun.javafx.scene.control.skin.ListViewSkin$2

现在,game_ptr中的索引是正确的.这是经过测试的.如果我运行以下代码,则没有警告:

list.getSelectionModel().select(game_ptr);
//list.scrollTo(game_ptr);

我正在使用嵌入式 tomcat，当我尝试启动服务器时，出现以下错误。我正在使用 tomcat 8.0.20 和 jdk8

这与jax-rs-2-0-change-default-implementation有关, 我有一个OSGi包,它包含cxf 2.7.8和openejb.cxf依赖项作为嵌入式依赖项添加.

当我尝试部署webapp时,我得到以下异常.当我在启动服务器时设置系统属性,因为-Djavax.ws.rs.ext.RuntimeDelegate=org.apache.cxf.jaxrs.impl.RuntimeDelegateImpl这可以解决.

但是在上面的链接中它说当我有META-INF/services/javax.ws.rs.ext.RuntimeDelegate文件的内容,因为org.apache.cxf.jaxrs.impl.RuntimeDelegateImpl这可以解决.

在我的OSGi包中,该文件存在于cxf-rt-frontend-jaxrs-2.7.8.jar但是这个jar嵌入在OSGi包中似乎没有得到正确的选择.我试图将相同的文件添加到OSGi包中,META-INF/services但它也不起作用.

有人可以告诉我有没有办法摆脱这个没有手动设置系统属性？
