Spring引导 - 不支持请求方法'POST'。尝试了一切

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。Spring引导 - 不支持请求方法'POST'。尝试了一切

我在尝试使用json创建员工端点时遇到此错误"Request method 'POST' not supported"。

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) { 
    } 

}

应用类：

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

我已经试过禁用csrf，增加对方法@ResponseBody，但似乎没有任何工作。

编辑

我打http://localhost:8080/employeeapp/employees与POST请求。该头包括Content-Type : application/json以及与此JSON在身：

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

而且，这是我在日志中看到，当我击中POST请求上述URL。

我查了春天启动日志，原来不被生成的映射，而是春天是映射到默认服务。任何想法为什么它可能会发生？

这时候你打与POST请求的URL发生，你没有相应的映射在控制器，URL 。使用POST请求打什么URL？请提供相关问题 –

您确定您要访问的请求正文和网址是否正确？你也可以尝试添加'@ExceptionHandler（HttpMessageNotReadableException.class） public ResponseEntity handleBadInput（HttpMessageNotReadableException ex）{ Throwable cause = ex.getCause（）;'给你的类检查输入是否有问题。你是否在控制台中发现任何其他错误？ – Gyan

您要调用哪个URL以及您的应用程序映射了哪个URL。看起来你的映射网址是错误的，它包含了'DispatcherServlet'或应用程序名称的映射。 –

以下可能有所帮助。

在部署应用程序时，spring启动显示控制台上所有可用的服务。检查POST方法以创建正在显示与否。检查是否与其他服务不存在矛盾。 GET/PUT/POST
如果没有部署服务，请尝试在其他服务之前添加'/' - GET，PUT，POST。
添加异常处理程序（link）以检查客户端输入请求以检查POJO结构。
检查URL - 如果添加配置应用程序/名称的任何全局路径（link）
尝试删除头 - 在Content-Type请求头和后请求再次

以下是可能发生的不同事情。不需要按顺序进行。

编辑：

运行以下命令，检查您的控制器是否被启用，通过弹簧的应用程序或不考虑。

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); 
     } 
    } 

    }

所以事实证明，spring-boot并没有将url映射到服务。在上面的帖子中添加日志。 –

“日志”是在部署期间还是在请求期间？ – VinayVeluri

最近的回复，但我被卷入工作。是的，事实证明包装结构是错误的。早些时候，我在'src/java'子目录下有我的代码。现在，将它们添加到'com.nikhil.practice'下并且工作。 –

如果@SpringBootApplication注释的类和控制器在不同的包中，它不会在默认的类扫描中选择它。

它几乎适用于所有演示，因为bootstrapping类（@SpringBootApplication注释类）和其他控制器类驻留在同一个包中并加载到spring上下文中。

//让您的类访问到春天喜欢这样

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

是的，@ThusharaAriyasena。我想到几个月前。无论如何，感谢您的帮助:) –

对我来说，当我用@RequestParam这个错误发生此

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

OR //给基本包名称方法定义中的：

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

     return new FinancialMsgResponse(); 
    }

所以当我删除@RequestParam错误

请求方法 'POST' 不支持

的消失。

好运

您可能需要修改jar在包装war

<artifactId>demo</artifactId>
