Spring引导 - 在http.get中使用rest控制器的angularjs返回状态404

Question

我试图从服务器获取数据使用JPA存储库和spring restcontroller传递给angularjs的http.get方法。但是当我在console.log中查看它时，它显示：angular.js：11048 GET http://127.0.0.1:8096/api/shipmentcount/sample 404（Not Found）。什么似乎是错的？

master.controller.js - 函数

    $scope.countTrips = function() {
    $http.get("/api/shipmentcount/sample").success(function(response) {
        console.log(response);
    });
}

$scope.countTrips();

ShipmentResources.java - 使用方法get请求映射

@RequestMapping(value="/shipmentcount/sample", method=RequestMethod.GET)
public List<Shipment> getshipmentCount() {
    return shipmentRepository.findAll();
}

shipment repository.Java

    package com.pahrsek.smartfleet.repository;

import java.util.Date;
import java.util.List;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.JpaSpecificationExecutor;
import org.springframework.data.jpa.repository.Query;
import org.springframework.stereotype.Repository;

@Repository
public interface ShipmentRepository extends JpaRepository<Shipment, Long>, JpaSpecificationExecutor<Shipment>{



    @Query( value="select new com.pahrsek.smartfleet.dto.ShipmentSummary(ship.status as status, "
            + "count(ship.id) as recordCount "
            + ") from Shipment ship where ship.company=?1 and ship.dateCreated>=?2 AND ship.dateCreated <=?3  group by ship.status")
    public List<ShipmentSummary> summaryByStatus(Company company, Date from, Date to);

    public List<Shipment> findFirst10ByVehicle(Vehicle vehicle);

    public List<Shipment> findByVehicle(Vehicle vehicle);

    public Shipment findByIdAndCompany(Long id, Company company);

    public List<Shipment> findByStatus(Status status);

    public List<Shipment> findByCustomerAndDepotAndOriginAndTypeAndCommodityTypeAndDateCreatedAfter(Customer customer, String depot, String origin, String type, String commodityType, Date dateCreated);

}

我想要做的是获取表装运中的状态列。我尝试创建一个休息控制器并将其与前端的angularjs集成。我找不到导致问题的原因。我认为它无法找到控制器/ api / shipmentcount / sample。我是春季靴子的新手。这是我第一次开发它。我正在尝试使用其他控制器，我想从服务器获取数据，以便在我的仪表板中的图表中使用。我使用chart.js作为我的图表。

Answer 1

从我在你的问题中看到的，你似乎有不同的路径。你打电话给：angularJS中的"/api/shipmentcount/sample"，但你已经宣布："/shipmentcount/sample"中的@RequestMapping。你缺少"/api"部分。

检查你的控制器是否有注释：@RequestMapping(value="/api")

如果没有，请检查你的appication.properties文件，如果你有类似的东西：server.contextPath=/api

如果不是，您可以更正您的端点方法，如下所示：

@RequestMapping(value="/api/shipmentcount/sample", method=RequestMethod.GET)
public List<Shipment> getshipmentCount() {
    return shipmentRepository.findAll();
}

另外，如果angularJS在不同的域或端口上运行，则需要提供服务器域和端口。

例如，如果角度在http://127.0.0.1:4200上运行，而你的服务器在http://127.0.0.1:8096上运行，你需要像这样纠正它：

$http.get("http://127.0.0.1:8096/api/shipmentcount/sample").success(function(response) {
    console.log(response);
});

您还需要允许CORS才能从不同的域发出请求。您可以使用方法上方的注释来执行此操作：@CrossOrigin

我希望有帮助:)
