Question

好的，我将简要说明。我用Maven，Eclipse和Spring MVC制作了一个API，当与“ tomcat7：run”一起运行时，它可以完美地工作。（端口9090）

运行服务器并在其中部署API时出现问题。服务器的工作方式很吸引人，http //：localhost：8080可以正常工作，当我尝试向API发出请求时就会出现问题，因为它似乎不存在，因为它不响应任何请求（每次404）。

该项目已部署，如果我从manager / html看到它，则可以看到它正在运行，因此我不知道可能是什么问题。我尝试搜索并搜索错误，但已达到极限。预先感谢！

如果您想查看任何代码，请问一下，因为在这种情况下我不知道要上传什么代码。

这是控制器类之一：

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：

Answer 1

好的，所以我解决了。经过大量的眼泪，经过大量的pom.xml处理之后，它开始工作了。

pom.xml仍然对我来说是个错误，但是我将发布与我处境相同的人所拥有的东西：)请记住，我在Maven项目中使用Angular，这就是为什么有一些节点插件等等。

将以下内容写入{MAVEN_HOME} /conf/settings.xml中，这也很重要（尽管我不知道这是否在api的正确部署和运行中起作用）

<settings>
   <servers>
      <server>
        <id>TomcatServer</id>
        <username>admin</username>
        <password>admin</password>
     </server>
  </servers>
</settings>

希望它对某人有帮助！
