Question

我目前正在关注有关带有Spring Cloud Security的Java微服务的Pluralsight教程。运行此应用程序后，我将从日志中复制生成的安全密码，并在邮递员中致电 http://localhost:9001/services/tolldata对用户：用户和密码：使用生成的密码使用基本身份验证。但是它给出了404 Not Found作为响应。

我尝试从应用程序设置更改端口，结果相同。试图在属性中也添加主机地址，结果相同。删除了server.servlet.context-path，结果相同。将@RequestMapping（“ / tolldata”）放在getTollData（）方法上方，结果相同。

这是我的主班。

@SpringBootApplication
@RestController
public class DemoApplication {

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

@RequestMapping("/tolldata")
public class TollUsage{
    public String id;
    public String stationId;
    public String licensePlate;
    public String timestamp;

    public List<TollUsage> getTollData(){
        TollUsage instance1 = new TollUsage("100", "station150", "B65GT1W", "2016-09-30T06:31:22");
        TollUsage instance2 = new TollUsage("101", "station119", "AHY673B", "2016-09-30T06:32:50");
        TollUsage instance3 = new TollUsage("102", "station150", "ZN2GP0", "2016-09-30T06:37:01");

        List<TollUsage> tolls = new ArrayList<TollUsage>();
        tolls.add(instance1);
        tolls.add(instance2);
        tolls.add(instance3);

        return tolls;
    }

    public TollUsage(){}

    public TollUsage(String id, String stationId, String licensePlate, String timestamp){
        this.id = id;
        this.stationId = stationId;
        this.licensePlate = licensePlate;
        this.timestamp = timestamp;
    }
}

}

这是我的application.properties

server.port=9001
server.servlet.context-path=/services

最后是pom.xml

Answer 1

将@RestController放到TollUsage类上，而不是DemoApplication上，然后将这些类拆分为不同的文件。

Answer 2

尝试一下：

  @SpringBootApplication
    public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
    }
    @RequestMapping(value = "/tolldata")
@RestController
    class TollUsage{
        public String id;
        public String stationId;
        public String licensePlate;
        public String timestamp;

        @GetMapping
        @CrossOrigin
        @ResponseBody
        public ResponseEntity<List<TollUsage>> getTollData(){
            TollUsage instance1 = new TollUsage("100", "station150", "B65GT1W", "2016-09-30T06:31:22");
            TollUsage instance2 = new TollUsage("101", "station119", "AHY673B", "2016-09-30T06:32:50");
            TollUsage instance3 = new TollUsage("102", "station150", "ZN2GP0", "2016-09-30T06:37:01");

            List<TollUsage> tolls = new ArrayList<TollUsage>();
            tolls.add(instance1);
            tolls.add(instance2);
            tolls.add(instance3);

            return new ResponseEntity<>(tolls, HttpStatus.OK);;
        }

        public TollUsage(){}

        public TollUsage(String id, String stationId, String licensePlate, String timestamp){
            this.id = id;
            this.stationId = stationId;
            this.licensePlate = licensePlate;
            this.timestamp = timestamp;
        }
    }

使用Spring Cloud Starter安全性的404 Not Found Spring Boot应用程序
