我的Android应用程序需要对不同的移动国家代码做出不同的反应
它似乎是硬编码到mcc310(美国).我可以TelephonyManager.getSimCountryIso()通过使用资源文件夹来读取此值,res/values-mcc123/但是如何在模拟器中设置此值？
我听说"jBPM"的开发者最近已转移到"Activiti BPMN 2"(例如:Tom).
我想知道jBPM的支持是否会结束.此外,我很高兴听到你的想法,即随着时间的推移,Activiti BPMN的改进是否会比jBPM更好或更有用？
我也想知道他们之间的利弊.
在Java中,URI该类是不可变的.
这是我目前正在修改端口的方式:
public URI uriWithPort(URI uri, int port) {
try {
return new URI(uri.getScheme(), uri.getUserInfo(), uri.getHost(), port,
uri.getPath(), uri.getQuery(), uri.getFragment());
} catch (URISyntaxException e) {
LOG.error("Updating URI port failed:",e);
return uri;
}
}
有更简单的方法吗？
是否有一种简单的方法可以在gradle任务中写入mercurial版本(或类似的外部命令):
我还不熟悉/熟悉,但我目前的努力看起来像这样:
task versionInfo(type:Exec){
commandLine 'hg id -i -b -t'
ext.versionfile = new File('bin/$baseName-buildinfo.properties')
doLast {
versionfile.text = 'build.revision=' + standardOutput.toString()
}
}
我通过IntelliJ IDEA(Ultimate ed.)运行Tomcat应用程序时在JSP中设置了断点.到目前为止,我可以按预期逐步完成JSP.
问题是:我无法解析Spring模型变量,例如${path}调试时. Evaluate Expression触发错误:"无法找到变量'path'".
作为一种解决方法,我可以使用显式引用模型值<c:set var="testPath" value="${path}">.这样我可以testPath在Variables»_jspx_page_context»属性中看到,但不是path.
我正在尝试使用Curl和API密钥上传到Google云端存储,但没有成功.错误消息似乎表明我缺少Content-length标头,但我没有.有任何想法吗？

<title>Error …我们的摇篮构建必须 --add-modules=java.xml.bind,java.activation,java.xml.ws.annotation要options.compilerArgs在JavaCompile建立与JDK9/10.这现在很好用,但这些模块已被弃用.
我想为可能删除这些模块的 JDK11做准备.
我曾尝试加入javax.xml.bind:jaxb-api:2.3.0,com.sun.xml.bind:jaxb-impl:2.3.0并com.sun.xml.bind:jaxb-core:2.3.0以compile和runtime,以及classpath在buildscript,但我仍然得到NoClassDefFoundError.
我错过了什么？

at …我一直在尝试用PHP 复制Gnu Find("find."),但似乎不可能接近它的速度.PHP实现使用至少两倍的Find时间.使用PHP有更快的方法吗？
编辑:我使用SPL实现添加了一个代码示例 - 它的性能等于迭代方法
EDIT2:从PHP调用find时,它实际上比本机PHP实现慢.我想我应该对我得到的东西感到满意:)

在我的战争中,Weblogic类加载器似乎更喜欢系统库而不是库WEB-INF/lib/.
我尝试过设置以下内容WEB-INF/weblogic.xml,但没有成功:
<weblogic-web-app>
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
</weblogic-web-app>
这只是给了我很多验证错误:
