驗證 jboss 部署期間的錯誤。 如何解決這個問題？

Question

當我在 Jboss 中部署我的應用程序時，出現以下錯誤

ERROR [org.jboss.msc.service.fail] (MSC service thread 1-6) MSC000001: Failed to start service jboss.deployment.subunit."test.ear"."hello.war".INSTALL: org.jboss.msc.service.StartException in service jboss.deployment.subunit."test.ear"."hello.war".INSTALL: WFLYSRV0153: Failed to process phase INSTALL of subdeployment "hello.war" of deployment "test.ear"

注意：class HelloWorldImpl 沒有覆蓋最終方法 getDetails。 它只是調用它的超級 class 最終方法 getDetails。

代碼：

class HelloWorldImpl extends Hello{
...
public void display() { 
...     
 Foo fooObj = (Foo)getDetails("test");
...
}
}               

class Hello{
public final Object getDetails(String id){
...
}
}

Answer 1

HelloWorldImpl 不可代理，因為它有一個繼承自 Hello 的 final 方法。

不可代理類不能有除@Dependent之外的 scope 。

如果你不能使用@Dependent scope，你可以從HelloWorldImpl中提取一個你需要的方法的接口，並將注入點更改為接口類型。

然后檢查有關此情況和解決方法的 WELD 文檔： https://docs.jboss.org/weld/reference/latest/en-US/html/injection.html#_client_proxies
