内容类型为application/x-www-form-urlencoded的Post请求在Spring中不起作用

@PostMapping(value = "/submitForm", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
public ResponseEntity<String> submitForm(@RequestParam String name, @RequestParam String email) {
    // 处理逻辑
    return ResponseEntity.ok("Form submitted successfully");
}

fetch('/submitForm', {
    method: 'POST',
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded'
    },
    body: new URLSearchParams({
        name: 'John Doe',
        email: 'john.doe@example.com'
    })
});

@PostMapping(value = "/submitForm", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
public ResponseEntity<String> submitForm(@RequestBody String formData) {
    // 这里无法正确解析表单数据
    return ResponseEntity.ok("Form submitted successfully");
}

@PostMapping(value = "/submitForm", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
public ResponseEntity<String> submitForm(@ModelAttribute FormData formData) {
    // 处理逻辑
    return ResponseEntity.ok("Form submitted successfully");
}

const params = new URLSearchParams();
params.append('name', 'John Doe');
params.append('email', 'john.doe@example.com');
