问题：

不支持Spring Boot请求方法“POST”。什么都试过了

陈项禹
2023-03-14

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) {
    }

}

应用程序类：

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

我尝试禁用CSRF，并在该方法上添加@responsebody，但似乎没有任何效果。

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

以下可能会有所帮助。

  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。检查一下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，请尝试在其他服务之前添加'/'。
  3. 添加异常处理程序（link）来检查客户端输入请求以检查POJO结构。
  4. 检查URL-如果有任何带有配置的app/name的全局路径。(link)
  5. 尝试删除请求头中的headers-content-type，并再次发布请求

以下是可能发生的不同事情。不需要按顺序跟随。

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);
        }
    }

    }
