java - 方法 POST 不支持 Netflix Eureka 和 ZUUL

Question

我正在用 JAVA 创建一个 Rest Controller 。当我在本地运行应用程序时，我可以执行 POST 操作。然后我创建一个 JAR，然后将其部署在服务器上。请注意，我使用 Netflix Eureka 进行服务发现，并使用 zuul 作为 API 网关。应用程序开始在服务器上正常运行，并且也在 Eureka 服务器中注册。但是当我使用 POST 服务时，它给我错误:405 Method Post not support 。

Controller 类

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
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;

import com.bp.budgetpulse.domain.FeedBackEmployeeDetails;
import com.bp.budgetpulse.service.FeedBackService;


@RestController
@RequestMapping(value = "/api/v1")
public class FeedBackController {

    @SuppressWarnings("unused")
    private final Logger logger = LoggerFactory.getLogger(FeedBackService.class);

    @Autowired
    private FeedBackService feedbackService;

    /**
     * This method to save the feedback details
     * 
     * @param feedbackDetails
     * @param userName
     * @return response
     */
    @RequestMapping(value = "/saveEmployeeFeedbackDetails", method = RequestMethod.POST)
    public String saveEmployeeFeedbackDetails(@RequestBody FeedBackEmployeeDetails empFeedbackDetails) {
        return feedbackService.saveEmployeeFeedbackDetails(empFeedbackDetails);
    }

    /**
     * 
     * this method to get the feedback details
     * 
     * @return feedback details
     */
    @RequestMapping(value = "/getFeedBackDetails/{email}", method = RequestMethod.GET)
    public FeedBackEmployeeDetails getFeedBackDetails(@PathVariable String email) {
        return feedbackService.getFeedBackDetails(email);
    }
}

Netflix Eureka 和 ZUUL 支持 POST 方法。 Netflix Eureka 和 ZUUL 不对 API 方法施加任何限制。以下是我编写的示例 Controller 代码，在 Netflix Eureka 和 ZUUL 环境中运行没有任何问题:

import com.aj.gradingservice.model.Grade;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
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;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;


@RestController
@RequestMapping("/")
public class GradeController {

    private static final Logger logger = LoggerFactory.getLogger(GradeController.class);

    @RequestMapping(value = "ping", method = RequestMethod.GET)
    public ResponseEntity<Map<String, String>> ping() {
        Map<String, String> response = new HashMap<>();
        response.put("message", "pong");
        return new ResponseEntity<>(response, HttpStatus.OK);
    }

    @RequestMapping(value = "grades", method = RequestMethod.GET)
    public ResponseEntity<List<Grade>> getGrades() {
        logger.info("In GradeController.getGrades(), fetching list of grades");
        List<Grade> grades = new ArrayList<>();
        grades.add(new Grade(1, "P001", "A+"));
        grades.add(new Grade(2, "C001", "A"));
        grades.add(new Grade(3, "M001", "B+"));
        return new ResponseEntity<>(grades, HttpStatus.OK);
    }

    @RequestMapping(value = "grade", method = RequestMethod.POST,
            consumes = MediaType.APPLICATION_JSON_VALUE,produces = MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<Grade> createGrade(@RequestBody Grade grade) {
        logger.info("Request received is: " + grade );
        Grade gradeCreated = new Grade(grade.getId(),grade.getStudentId(),grade.getGrade());
        return new ResponseEntity<>(gradeCreated, HttpStatus.OK);
    }
}
