jax-rs - 使用 RESTEasy、Weld 和 Wildfly 失败的 @Inject 对象

我正在尝试使用 RESTEasy 和 Weld 进行注入(inject)来创建 REST Web 服务。当包部署在 Wildfly 上时,我没有问题,但是当尝试测试服务时,我收到以下错误。

我不知道如何解决这个问题。

有人可以帮助我吗?

最佳答案

如果您不使用特定的 Weld 或 Resteasy 功能,则不应添加 Weld 和 Resteasy 依赖项。如果您这样做,您应该将这些依赖项放在 provided 范围内。否则它将被打包在您的 WAR 中。

但是查看您的代码,您似乎没有使用特定的 Weld 或 Resteasy 功能。在这种情况下,我建议仅添加 Java EE api 的单个依赖项,仅此而已:

    <dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>7.0</version>
<scope>provided</scope>
</dependency>

Wildfly 将在运行时提供所有实现。
