spring - war 、 Spring 和 Tomcat 7

Question

我想在 Apache tomcat 7 服务器上使用 Spring Framework 创建一个 REST Web 服务。

因此，我从教程中获取了 build.gradle，我创建了我的 Ws 并使用 main 方法创建了主 Controller (/greeting) 和我的 Application.class。

然后，我 gradle clean build 我的解决方案，我得到了一场 war 。

我用 tomcat 服务器的管理器 ui 部署了这场 war ，当我尝试请求 url localhost:8080/mySoft/greeting 时，出现 404 错误。

谁能帮帮我？

我遵循了教程，但我像部署 war 一样部署应用程序。所以它应该在 localhost:8080/myApp/greeting 上。 localhost:8080/greeting deosnt 工作...

    Application.java

        package main.java;

    import org.springframework.boot.SpringApplication;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.web.servlet.config.annotation.EnableWebMvc;

    @Configuration
    @EnableWebMvc
    public class Application {

        public static void main(String[] args) {
            SpringApplication.run(Application.class, args);
        }

    }

    HelloController.java

    package com.id2tel.controller;

    import java.util.concurrent.atomic.AtomicLong;

    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestParam;
    import org.springframework.web.bind.annotation.ResponseBody;

    @Controller
    public class HomeController {

        private static final String template = "Hello, %s!";
        private final AtomicLong counter = new AtomicLong();

        @RequestMapping("/greeting")
        public @ResponseBody
        Greeting greeting(
                @RequestParam(value = "name", required = false, defaultValue = "World") String name) {
            return new Greeting(counter.incrementAndGet(), String.format(template,
                    name));
        }
    }

以及spring提供的基本问候类。

我创建了 HelloWebXml 类。

我检查了我的 catalina 日志，我发现了这个:
