我遇到了一个问题，我想我可能会看看是否有人知道答案。这不是太大的问题，因为实际上是在注入资源 - 但是控制台正在显示资源无法解决的信息警告。

EAP 5.1.2 中不会出现此问题。我只是好奇是否有其他人遇到了这个问题，并且可能我在 EAP 7 中没有正确地做事，因此有一个解决方法。

背景：

  1. 打包在 EAR 中的 EJB Web 服务。EAR 没有 application.xml 或 jboss-deployment-structure.xml

注意：虽然我确实尝试添加一个 jboss-deployment-structure.xml 只是为了看看它是否有帮助。

  1. 无状态 EJB 是一种 Web 服务

这是 ejb-jar.xml 文件中的一个片段：

        <env-entry>
            <description>Variable to distinguish between prod, uat and qa environments</description>
            <env-entry-name>net.mycompany.mypackage.mysubpackage.MyWSService.isUAT</env-entry-name>
            <env-entry-type>java.lang.Boolean</env-entry-type>
            <env-entry-value>false</env-entry-value>
        </env-entry>

        <env-entry>
            <description>Variable to distinguish between prod, uat and qa environments</description>
            <env-entry-name>isQA</env-entry-name>
            <env-entry-type>java.lang.Boolean</env-entry-type>
            <env-entry-value>false</env-entry-value>
        </env-entry>

正如你所看到的，我尝试了两种方式，例如在 env-entry-name 中使用完整的包和类名以及普通的旧 env 条目名称

下面是 Web 服务代码片段：

@SuppressWarnings("unused")
@Stateless
@Local(IMyWSService.class)
@WebService
public class MyWSService implements IMyWSService {

    @Resource(name = "isUAT")
    private boolean isUAT;
    @Resource
    private boolean isQA;

    @WebMethod
    @ResponseWrapper(localName="doSomethingResponse", className="Response", targetNamespace="http://model.mysubpackage.mypackage.net")
    public Response doSomething
    (@WebParam(name="param1", mode=Mode.IN) String param1
    , @WebParam(name="param2", mode=Mode.IN) String param2
    , @WebParam(name="param3", mode=Mode.IN) String param3) {

    //more and more code
    .
    .
    .
    //pertinent method
    initAndSetEnvEntrieVars();
    .
    .
    .
    //the method which actually utilizes the environment variables
    private void initAndSetEnvEntrieVars() {
    //setup env-entry related vars
            if(isUAT){
                System.out.println("We're in UAT");

            }else if(isQA){
                System.out.println("We're in QA");
            }
    }

注意：再一次，这些值实际上是被注入的，为了简洁起见，我从代码中删除了大约 15 个值。

这是 JBoss 控制台中的输出

再一次，这更像是一个麻烦，但我觉得我会由你们所有人运行它，以防其他人被困在研究它几个小时。

更新：抱歉，我没有意识到 StackExchange 和 StackOverFlow 之间的区别 - 一直想知道为什么不同的名称......但太忙了，无法找出原因。

所以在从好人那里得到一些帮助/建议之后，例如 JBoss 论坛中的 Alessio Soldano 和 jaikiran pai，Alessio 基本上说：“嗨，我需要去检查代码以确认，但我认为那里发生的事情是WS层基本上通过不同的机制来注入值.首先它尝试让Apache CXF层解析值,如果失败(这里显示的日志)它使用内部JBoss机制,这就是实际得到的此处来自 ejb-jar.xml 描述符的值。”

和...

“只需忽略日志中的那条消息，你就完成了。这基本上是一个内部问题，日志来自 apache cxf，所以在这种情况下我们无能为力来避免它。你链接的线程与稍微不同的线程有关由错误引起的场景（嗯，当时缺少一个功能），但这已经解决了。”

论坛帖子是： JBoss EAP 7 - Injected Resources 上的错误跟踪

如果有人想进一步跟进 - 看起来我们现在只是坚持下去
