According to Java tutorial on Oracle, if deprecated method marked with @Deprecated annotation is used, compiler should be giving warning on compilation. But with following code sample, I am not getting any warning in the console. Java version used: 1.8.0_112 Please let me know what could be missing here. Thanks. public class PreDefinedAnnotationTypesTest { /** * This method is deprecated
根据Oracle的Java教程,如果使用标记为@Deprecated注释的不推荐使用的方法,编译器应该在编译时给出警告。 但通过以下代码示例,我没有在控制台中收到任何警告。 使用的Java版本:1.8.0_112 请让我知道这里可能会丢失什么。 谢谢。 public class PreDefinedAnnotationTypesTest { /** * This method is deprecated. * @deprecated */ @Deprecated public void m1(){ } public static void main(String[] args) {
I'm looking to make my code more readable as well as use tooling like IDE code inspection and/or static code analysis (FindBugs and Sonar) to avoid NullPointerExceptions. Many of the tools seem incompatible with each others' @NotNull / @NonNull / @Nonnull annotation and listing all of them in my code would be terrible to read. Any suggestions of which one is the 'best'? Here is
我期望让代码更具可读性,并使用IDE代码检查和/或静态代码分析(FindBugs和Sonar)等工具来避免NullPointerException。 许多工具似乎与其他人的@NotNull / @NonNull / @Nonnull注解不兼容,并且在我的代码中列出所有这些工具会非常糟糕。 任何建议哪一个是'最好的'? 以下是我找到的等效注释列表: javax.validation.constraints.NotNull 创建用于运行时验证,而不是静态分析。 文件 edu.umd.cs.findbugs.annot
Executing the following gives me the differences in line count between local changes and the remote versions of the file: git diff --shortstat C:devSprint7 origin/master:C:devSprint7 Example result: 18 files changed, 11 insertions(+), 8 deletions(-) Please, how do I calculate the total number of unique changed lines? For instance, if line 5 of Login.jsp file is deleted and same line 5 is re
执行以下操作会给我本地更改和文件的远程版本之间的行计数差异: git diff --shortstat C:devSprint7 origin/master:C:devSprint7 示例结果: 18 files changed, 11 insertions(+), 8 deletions(-) 请问,如何计算唯一更改的行的总数? 例如,如果Login.jsp文件的第5行被删除,并且第5行被另一行(或字符串)替换(即删除和插入在第5行完成),我希望这被计为1改变的行。 我可以通过总结插入和删除从上面的命令中得到这
是否有任何适用于Ruby或Java的OData 提供程序 SDK? There are none, unfortunately. There are only clients. I've used ruby_odata successfully. It works well against a simple model and provides mappings for all the basic query options, although you do need to know the operators (like eq, substringof, etc). I did run into a more complex model and needed to tweak the code a bit. It's easy
是否有任何适用于Ruby或Java的OData 提供程序 SDK? 不幸的是,没有一个。 只有客户。 我已经成功地使用了ruby_odata。 它对一个简单的模型运行良好,并为所有基本查询选项提供映射,尽管您确实需要了解运算符(如eq,substringof等)。 我遇到了一个更复杂的模型,需要稍微调整代码。 很容易找到:http://odetocode.com/Blogs/scott/archive/2010/07/11/odata-and-ruby.aspx 这里有Ruby和Java的提供者:http://www.oda
MsWord uses Wingdings and Symbol characters for bullets, by default their hex values are F0A7 and F0B7. I want to convert the bullets to their Unicode equivalents. Of course, it depends on the actual font used, so F0A7 Wingding would become Unicode 25AA (●). I've found a partial mapping from Wingdings to Unicode and from Symbol to Unicode. Is there a general a library (preferably in Java)
MsWord使用Wingdings和Symbol字符作为项目符号,默认情况下它们的十六进制值是F0A7和F0B7。 我想将项目符号转换为它们的Unicode等价物。 当然,这取决于使用的实际字体,所以F0A7 Wingding将成为Unicode 25AA(●)。 我发现了从Wingdings到Unicode以及从Symbol到Unicode的部分映射。 有没有一个通用的库(最好是Java)或者这些映射的数据库? 这些信息嵌入在.ttf文件中 - 我不确定如何在java中访问它。 AFAIK java.awt.F
Hi I'm working on a project and try to add css to a page but its not loading and when i check srourcecode at the browser I get a : Resource interpreted as Stylesheet but transferred with MIME type text/html: I tried to load css in every way, with - " rel="stylesheet"> - - even with @import file ( not a best practice but i tried...) and its not working.

I've created .csv file using excel and I wrote following code using apache tika: public static boolean checkThatMimeTypeIsCsv(InputStream inputStream) throws IOException { BufferedInputStream bis = new BufferedInputStream(inputStream); AutoDetectParser parser = new AutoDetectParser(); Detector detector = parser.getDetector(); Metadata md = new Metadata(); MediaType mediaT
我使用excel创建了.csv文件,我使用apache tika编写了以下代码: public static boolean checkThatMimeTypeIsCsv(InputStream inputStream) throws IOException { BufferedInputStream bis = new BufferedInputStream(inputStream); AutoDetectParser parser = new AutoDetectParser(); Detector detector = parser.getDetector(); Metadata md = new Metadata(); MediaType mediaType = detector.detect(bi
There are tons of ways to get the Mime Type from a given InputStream or File. But given a MimeType or (in HTTP terms: content type) how do I get a list of file extensions. Java's activation library has MimetypesFileTypeMap but that goes File Ext -> Mime Type. I need Mime Type -> File Ext. It seems like I would have to copy the pseudo private code that is in com.sun.activation to l
有很多方法可以从给定的InputStream或File获取MIME类型。 但是,给定一个MimeType或(以HTTP的形式:内容类型)我如何获得文件扩展名列表。 Java的激活库有MimetypesFileTypeMap,但是文件分机 - > Mime类型。 我需要Mime Type - > File Ext。 看起来我必须复制com.sun.activation中的伪私有代码来加载MIME类型映射。 Apache带有一个mime.types文件。 你可以解析这个文件并使用它来映射文件扩展名到内容类型,反
I have a external jar file named "xxx.jar". I use "xxx.jar" in my GWT project. When I attempt to build the JavaScript version of my project in Ant, I get one of the following type of errors at every location in which I use xxx. I get a error of this kind when doing the "gwtc" task in Ant, the javac compilation process proceeds just fine. [ERROR] Line 45: No sou
我有一个名为“xxx.jar”的外部jar文件。 我在我的GWT项目中使用“xxx.jar”。 当我尝试在Ant中构建我的项目的JavaScript版本时,在我使用xxx的每个位置出现以下类型的错误之一。 在Ant中执行“gwtc”任务时出现此类错误,javac编译过程进行得很顺利。 [错误]第45行:没有源代码可用于org.xxx.ObjectName类型; 你忘了继承一个必需的模块吗? 好吧,很显然,它无法看到/使用xxx.jar。 然而,解决这个问题在GWT中并不像在“普通
