如何解决Spring Boot-请求方法'POST'不支持尝试了一切
遵循可能会有所帮助。
- 在部署应用程序时，spring boot在控制台上显示所有可用服务。检查创建的POST方法是否显示。检查与其他服务不应有任何矛盾。GET / PUT / POST
- 如果没有部署服务，请尝试在其他服务（GET，PUT和POST）之前添加“ /”。
- 添加异常处理程序以检查客户端输入请求以检查POJO结构。
- 检查URL-如果在配置中添加了应用程序/名称的全局路径
- 尝试删除标题-请求标题中的Content-Type并再次发布请求
以下是可能发生的不同事情。无需按顺序进行。
编辑：
运行以下命令检查spring应用程序是否启用并考虑了控制器。
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);
}
}
}
解决方法
我正在使用Spring Boot和MongoDB构建一个Web应用程序，它将仅对员工文档执行CRUD操作。
"Request method 'POST' not supported"当我尝试使用json命中create employee端点时出现此错误。
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) {
}
}
应用类别：
@SpringBootApplication
public class Application {
public static void main(String[] args) throws Exception {
SpringApplication.run(Application.class,args);
}
}
我尝试禁用csrf，添加@ResponseBody了方法，但似乎没有任何效果。
编辑
我遇到http://localhost:8080/employeeapp/employees了POST请求。标题包含Content-Type :
application/json，并在正文中包含以下json：
{
"id" : 1,"name" : "nikhil","dept" : "DCX"
}
另外，这是我通过POST请求点击上述URL时在日志中看到的内容。

我检查了Spring引导日志，结果是未生成映射，而是spring映射到默认服务。知道为什么会发生吗？
