定位.jar文件中的内部目录 - java [英] Targeting inner directories within a .jar file -- java

问题描述

我有一个非常好的Web服务客户端，其中有一行定义了WSDL的位置：

I have a web service client which works perfectly fine, within which there is a line that defines the location of the WSDL:

@WebServiceClient(name = "CReceiveMOMessageService", 
                  targetNamespace = "http://...", 
                  wsdlLocation = "CReceiveMOMessageService.wsdl")

代码段应该作为可运行的JAR导出，并且可以在远程位置工作。

The code piece should be exported as a runnable JAR and is intended to work on a remote location.

当我如上所述定义WSDL的位置时，它会在我运行JAR文件的目录中查找WSDL文件。相反，我想要做的是将WSDL文件添加到项目文件夹并在此之后导出为JAR，并以指向WSDL的方式配置 wsdlLocation 参数在JAR文件中。

When I define the location of the WSDL as above, it looks for a WSDL file at the directory in which I run the JAR file. Instead what I would like to do is to add the WSDL file to the project folder and export as JAR after that, and configure wsdlLocation parameter in a way that it points to the WSDL within the JAR file.

如何实现？

推荐答案

可以将WSDL添加到JAR。似乎惯例是将WSDL放在JAR的 META-INF / wsdl 位置（尽管Oracle工具似乎支持 META-INF / wsdls （参见第9点例如，这个Oracle教程。

It is possible to add the WSDL to the JAR. It seems that the convention is to place the WSDL in the JAR at the META-INF/wsdl location (although Oracle tools seem to favor META-INF/wsdls (see point 9 of this Oracle tutorial for example).

我没有使用Eclipse的Oracle Enterprise Pack，我猜OEPE ClientGen任务正确生成了指定在JAR中打包WSDL时的客户端类，但我不认为它与传递 -wsdllocation META-INF / wsdls / YourService.wsdl 参数相同运行 wsimport.exe ：

I haven't used the Oracle Enterprise Pack for Eclipse and I guess the OEPE ClientGen task does the correct generation of the client classes when you specify to package the WSDL inside the JAR but I don't think it's the same as passing a -wsdllocation META-INF/wsdls/YourService.wsdl parameter when running wsimport.exe:

wsimport.exe 将输出 @ WebServiceClient（... wsdlLocation =META-INF / wsdls / YourService.wsdl）但通常也会生成这样的代码在类的静态初始值设定项中：

wsimport.exe will output @WebServiceClient(... wsdlLocation = "META-INF/wsdls/YourService.wsdl") but will also normally generate code like this in the static initializer of the class:

baseUrl = YourService.class.getResource(".");
url = new URL(baseUrl, "META-INF/wsdls/YourService.wsdl");

它仍将指向一个根文件夹，然后它将所提供的WSDL路径添加到最终得到一个不存在的路径。

which will still point to a root folder to which it then adds the provided WSDL path to finally get a non existent path.

您必须在生成后更改类，以包含类似的内容：

You will have to change the class after it's generated to include something like this instead:

url = YourService.class.getClassLoader().getResource("META-INF/wsdls/YourService.wsdl");

现在将指向JAR。当然，在构建客户端JAR时，您必须在该位置打包WSDL。

which will now point within the JAR. Off course you must pack the WSDL at that location when building the client JAR.
