JRE 9模块需要找不到的模块(JRE 9 module requires a module that was not found)

JRE 9模块需要找不到的模块(JRE 9 module requires a module that was not found)

运行我的项目时，我得到的错误是：

Error occurred during initialization of boot layer java.lang.module.FindException: Module java.xml.soap not found, required by java.xml.ws

据我所知， java.xml.ws是一个JRE模块而java.xml.soap不是，基于文档中提供的列表。 我开始我的程序的方式是：

java --upgrade-module-path c:/git/projectdir --add-modules java.xml.bind,java.xml.ws,java.xml.ws.annotation -cp c:/git/projectdir/Uservice.jar com.gert.DynamicService "arg1" "arg2" "arg3"

当我尝试将java.xml.soap添加到add-modules时，它无法找到该模块。

我的问题是：

java.xml.soap是一个JRE模块吗？ 如果java.xml.soap不是JRE模块，为什么java.xml.ws模块依赖于不在JRE中的模块？ 在哪里可以找到java.xml.soap模块？

我正在使用java 9.0.1

When running my project I get the error that says:

Error occurred during initialization of boot layer java.lang.module.FindException: Module java.xml.soap not found, required by java.xml.ws

As far as I understand java.xml.ws is a JRE module and java.xml.soap is not, based on the list provided in the documentation. The way I start my program is:

java --upgrade-module-path c:/git/projectdir --add-modules java.xml.bind,java.xml.ws,java.xml.ws.annotation -cp c:/git/projectdir/Uservice.jar com.gert.DynamicService "arg1" "arg2" "arg3"

When I try to add java.xml.soap to add-modules it cannot find the module.

My question is:

is the java.xml.soap a JRE module? if java.xml.soap isn't a JRE module, why does the java.xml.ws module depend on a module that isn't in the JRE? where to find the java.xml.soap module?

I'm using java 9.0.1

java.xml.soap是JRE模块吗？

不，这不是一个平台模块。 运行java --list-modules ，你不会在输出中看到java.xml.soap 。

如果java.xml.soap不是JRE模块，为什么java.xml.ws模块依赖于不在JRE中的模块？

有两个java.xml.ws模块。

第一个是平台模块，它已被弃用（您不应该使用它）。

第二个是独立模块，它作为jaxws-api部署到Maven中心（你应该使用这个模块）。

虽然这两个模块相似，但存在许多差异。 其中一个是独立的java.xml.ws有自己的依赖项。 例如， java.xml.ws依赖于java.xml.soap ，它也被部署到Maven中心（如javax.xml.soap-api ）。

在哪里可以找到java.xml.soap模块？

往上看。 你可以在Maven中心找到它。 如果您使用Maven，它应该作为jaxws-api的依赖项自动选取。

我认为，可升级文件夹c:/git/projectdir缺少java.xml.soap 。 您应该从.m2\repository\javax\xml\soap\javax.xml.soap-api复制jar。

Is the java.xml.soap a JRE module?

No, this is a not a platform module. Run java --list-modules and you will not see java.xml.soap in the output.

If java.xml.soap isn't a JRE module, why does the java.xml.ws module depend on a module that isn't in the JRE?

There are two java.xml.ws modules.

The first one is a platform module and it is deprecated (you should not use it).

The second one is a standalone module which is deployed to Maven central as jaxws-api (you should use this module).

While these two modules are similar, there are a number of differences. One of them is that standalone java.xml.ws has its own dependencies. E.g. java.xml.ws depends on java.xml.soap which is deployed to Maven central too (as javax.xml.soap-api).

Where to find the java.xml.soap module?

See above. You can find it in Maven central. If you use Maven, it should be picked up automatically as a dependency of jaxws-api.

I think, java.xml.soap is missing in your upgradeable folder c:/git/projectdir. You should copy the jar from .m2\repository\javax\xml\soap\javax.xml.soap-api.
