java - Spring Jersey：如何摆脱 web.xml？

Question

我将我的应用程序创建为（链接）

public class InventoryApplication extends ResourceConfig {
    public InventoryApplication() {
        packages("com.org.my_services.inventory.services");
    }
}

我有空白web.xml，我想摆脱

当我使用货物在 tomcat 中部署我的战争时mvn cargo:run，它失败了

我怎样才能告诉我的容器寻找InventoryApplication？

Answer 1

您的类路径中需要 jersey-servlet。

看：

• 没有 web.xml 的 Jersey 设置
• 使用 Jersey 和 @ApplicationPath 注解加载资源
