org.springframework.web.bind.MissingServletRequestParameterException: Required request parameter 'id' for method parameter type String is not present

This exception occurs when a required request parameter is missing in the request. In your case, the parameter 'id' is required for the controller method parameter to be resolved, but it is not present in the request.
To resolve this issue, you need to make sure that the request contains the required 'id' parameter. You can also use the `@RequestParam` annotation in the controller method signature to specify that the 'id' parameter is required, like this:
```
@RequestMapping("/example")
public String exampleMethod(@RequestParam("id") String id) {
// your code here
}
```
This will throw a `MissingServletRequestParameterException` if the 'id' parameter is not present in the request. You can also provide a default value or make the parameter optional by using the `defaultValue` and `required` attributes of the `@RequestParam` annotation.
