Java Spring boot - 不支持请求方法“POST”。什么都试过了

Spring boot - Request method 'POST' not supported. Tried everything

提问by Nikhil Vibhav

I'm building a web application using Spring Boot and MongoDB which will simply perform CRUD operations for employee Documents.

我正在使用 Spring Boot 和 MongoDB 构建一个 Web 应用程序，它将简单地为员工文档执行 CRUD 操作。

I'm getting this error "Request method 'POST' not supported"when I try to hit the create employee endpoint with the json.

"Request method 'POST' not supported"当我尝试使用 json 创建员工端点时出现此错误。

My controller class is:

我的控制器类是：

@RestController
@RequestMapping("/employeeapp/employees")
public class EmployeeController {

    private final EmployeeService service;

    @Autowired
    public EmployeeController(EmployeeService service) {
        this.service = service;
    }

    @RequestMapping(method = RequestMethod.POST)
    @ResponseStatus(HttpStatus.CREATED)
    public
    @ResponseBody
    Employee create(@RequestBody @Valid Employee employeeEntry) {
        return service.create(employeeEntry);
    }

    @RequestMapping(value = "{id}", method = RequestMethod.DELETE)
    public Employee delete(@PathVariable("id") long id) {
        return service.delete(id);
    }

    @RequestMapping(method = RequestMethod.GET)
    public List<Employee> findAll() {
        return service.findAll();
    }

    @RequestMapping(value = "{id}", method = RequestMethod.GET)
    public Employee findById(@PathVariable("id") long id) {
        return service.findById(id);
    }

    @RequestMapping(value = "{id}", method = RequestMethod.PUT)
    public Employee update(@RequestBody @Valid Employee employeeEntry) {
        return service.update(employeeEntry);
    }

    @ExceptionHandler
    @ResponseStatus(HttpStatus.NOT_FOUND)
    public void handleEmployeeNotFound(EmployeeNotFoundException exception) {
    }

}

Application class:

应用类：

@SpringBootApplication
public class Application {
    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }
}

I've tried disabling csrf, adding @ResponseBodyon the method but nothing seems to work.

我试过禁用csrf，添加@ResponseBody方法，但似乎没有任何效果。

EDIT

编辑

I'm hitting http://localhost:8080/employeeapp/employeeswith the POST request. The headers include Content-Type : application/jsonand with this json in the body:

我正在http://localhost:8080/employeeapp/employees处理 POST 请求。标题Content-Type : application/json在正文中包含并带有此 json：

{
    "id" : 1,
    "name" : "nikhil",
    "dept" : "DCX"
}

Also, this is what i see in the logs when I hit the above URL with POST request.

此外，这就是我在使用 POST 请求点击上述 URL 时在日志中看到的内容。

I checked the Spring boot logs, turns out the mappings are not being generated and instead spring is mapping to default services. Any idea why it might be happening?

我检查了 Spring 启动日志，结果没有生成映射，而是 spring 映射到默认服务。知道为什么会发生吗？

Following might help.

以下可能会有所帮助。

1. While you deploy the application, spring boot displays all the available services on the console. Check the POST method to create is being displayed or not. Check that there shouldn't be any contradiction with other services. GET/PUT/POST
2. If there are services not deployed, try adding '/' before other services - GET, PUT, POST.
3. Adding exception handler(link) to check the client input request to check the POJO structure.
4. Check the URL - If any global path for app/name added with configuration.(link)
5. Try to remove headers - Content-Type in the request header and post the request again

1. 在部署应用程序时，spring boot 会在控制台上显示所有可用的服务。检查要创建的 POST 方法是否显示。检查不应该与其他服务有任何矛盾。获取/放置/发布
2. 如果有未部署的服务，请尝试在其他服务 - GET、PUT、POST 之前添加“/”。
3. 添加异常处理程序（链接）以检查客户端输入请求以检查 POJO 结构。
4. 检查 URL - 如果添加了配置的应用程序/名称的任何全局路径。（链接）
5. 尝试删除标头 - 请求标头中的 Content-Type 并再次发布请求

Following are different things that can happen. Need not to be followed in order.

以下是可能发生的不同事情。不必按顺序进行。

EDIT:

编辑：

Run the following to check whether your controller is being enabled and considered by the spring application or not.

运行以下命令以检查您的控制器是否被 spring 应用程序启用和考虑。

import java.util.Arrays;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        ApplicationContext ctx = SpringApplication.run(Application.class, args);

        System.out.println("Let's inspect the beans provided by Spring Boot:");

        String[] beanNames = ctx.getBeanDefinitionNames();
        Arrays.sort(beanNames);
        for (String beanName : beanNames) {
            System.out.println(beanName);
        }
    }

    }

If your @SpringBootApplication annotated class and controller are in different packages it does not pick it by default class scan.

如果您的 @SpringBootApplication 注释类和控制器位于不同的包中，则默认类扫描不会选择它。

It works in almost all demos because bootstrapping class (@SpringBootApplication annotated class) and rest controller class reside in the same package and loaded to spring context.

它适用于几乎所有演示，因为引导类（@SpringBootApplication 注释类）和其余控制器类驻留在同一个包中并加载到 spring 上下文。

// Make your class accessible to spring like this

// 让你的类可以像这样被 spring 访问

@SpringBootApplication(scanBasePackageClasses = {GreetingController.class})
public class BootPocApplication {

OR // give the base package name like this

或 // 像这样给出基本包名

@SpringBootApplication(scanBasePackages = {"com.tryout"})
public class BootPocApplication {

For me this error occurred when i used @RequestParamin method definition:

对我来说，当我在方法定义中使用@RequestParam时发生了这个错误：

@RequestMapping(value = "/balance",method = RequestMethod.POST,produces = MediaType.APPLICATION_JSON_VALUE)
    public FinancialMsgResponse balance(@RequestParam(value = "requestMessage") FinancialMsgRequest requestMessage) throws Exception {

        return new FinancialMsgResponse();
    }

So when i remove the @RequestParamthe error

所以当我删除@RequestParam错误时

Request method 'POST' not supported

不支持请求方法“POST”

is gone away.

消失了。

good luck

祝你好运

回答by Khalil Mejdi

Just follow this

只要按照这个

@Controller
@RequestMapping(
        method={RequestMethod.POST,RequestMethod.GET,RequestMethod....} 
    )

public class YourController{
.
.
.
}

回答by Maayan Hope

For me the issue was that the @RequestBody class was not accessible since it was an internal class.

对我来说，问题是 @RequestBody 类无法访问，因为它是一个内部类。

Making it public/static made it accessible and solved this issue

将其设为 public/static 使其可访问并解决了此问题

public static class MyClassDto {
        public String   name;
        public String   comment;
        public String   key;
}
