【问题描述】:
我正在尝试实现简单的 java Rest 应用程序并将其部署到 Tomcat 服务器。 (需要Tomcat,所以Tomee不是一个选项)
这是我项目的结构:
根pom.xml的内容:

web.xml 的内容:

"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>

RestApplication.java 的内容:
package org.example.rest;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
@ApplicationPath("rest")
public class RestApplication extends Application {
}
TestBean.java 的内容:
package org.example.rest;
import javax.ejb.Stateless;
@Stateless
public class TestBean {
public String test() {
return "Test Bean";
}
}
TestResource.java 的内容:
package org.example.rest;
import javax.ejb.Stateless;
import javax.inject.Inject;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
@Path("/test")
@Stateless
public class TestResource {
@Inject TestBean testBean;
@GET
public String test() {
return testBean.test();
}
}
正如您在 tomee-app pom.xml 中看到的,我已经配置了 maven 插件 tomee-maven-plugin 和 cargo-maven2-plugin(容器设置为 tomcat9x),这是我发现的唯一一个运行 Tomcat 9 的 maven 插件。
有了 Tomee,一切正常,Jax-Rs 正在运行,测试 bean 的注入工作正常。
但是对于 Tomcat,我至少无法让 CDI 正常工作。我尝试了在 Tomcat、OpenWebBeans、Apache CXF 等上找到的几个选项。但我总是发现 ether Jax-Rs not running on Injection doesn't work.
我没有发布我遇到的错误,因为我尝试了很多事情并最终出现了一堆不同的错误。
我更喜欢使用 OpenWebBeans 和 Apache CXF,因为 Tomee 使用它们,但到目前为止找不到任何工作说明。
我尝试按照这些instructions 让 OpenWebBeans 与 Tomcat 以及 Glassfish Jersey Containers 一起运行,但我在注入 TestBean 时遇到错误。
