Maven API 在服务器上部署时没有响应 (Tomcat 7)

Question

好的，那我就简单的解释一下。我用 Maven、Eclipse 和 Spring MVC 制作了一个 API，它在运行 "tomcat7:run" 时完美运行。 (端口 9090)

当运行服务器并在那里部署 API 时，问题就来了。服务器工作得很好，http//:localhost:8080 工作完美，当我尝试向 API 发出请求时出现问题，因为它似乎不存在，因为它没有响应任何请求（每次 404）。

项目已部署，如果我从 managers/html 观看它，我可以看到它是运行，所以我不知道可能是什么问题。我试图搜索并搜索错误，但已达到我的极限。提前致谢！

如果您想查看任何代码，请直接询问，因为在这种情况下我不知道要上传什么代码。

这是控制器之一类:

package com.autentia.spring.controller;

import com.autentia.spring.model.Course;
import com.autentia.spring.service.CourseService;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@CrossOrigin("*")
@RestController
public class CourseController {

    @Autowired
    private CourseService courseService;

    @RequestMapping(value = "/", method = RequestMethod.GET, headers = "Accept=application/json") //This method was a get, post is just for testing
    public ResponseEntity<String> welcome(@RequestBody String body) {
        System.out.println("In the UserController::index");
        return new ResponseEntity<>("It works!", HttpStatus.OK);
    }

    @RequestMapping(value = "/courses", method = RequestMethod.GET)
    public ResponseEntity<List<Course>> users() {
        System.out.println("Getting all courses");
        List<Course> list = courseService.getAllCourses();
        System.out.println("List: " + list);
        return ResponseEntity.ok().body(list);
    }

    @RequestMapping(value = "/courses", method = RequestMethod.POST, headers = "Accept=application/json")
    public ResponseEntity<String> insertCourse(@RequestBody Course course) {
        System.out.println("Inserting course: " + course);
        course.setId((long)0);
        // boolean teacherSaved = teacherService.insertTeacher(teacher);
        courseService.insertCourse(course);
        return new ResponseEntity(course.getId(), HttpStatus.OK);
    }
}

这是部署应用程序时的日志：

好的，所以我解决了。经过大量的眼泪，经过与 pom.xml 的大量杂耍之后，它成功了。

pom.xml 对我来说仍然是个谜，但我会 post 我为和我处境相同的人提供的东西 :) 请记住，我正在使用 Angular 在我的 Maven 项目中，这就是为什么有一些节点插件等的原因。

        <username>admin</username>
