我正在使用Java和mongoDB开发webApp，但是当我尝试保存对象“ Student”时，出现以下错误。
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).

这是我的pom.xml的mongo驱动程序依赖项
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongodb-driver</artifactId>
<version>3.4.2</version>
</dependency>
我按照老师的步骤创建了资源库，但是这个问题出现了，我无法解决。
这是我的StudentController：
@Controller
public class StudentController {
@Autowired
private StudentRepository studentRepository;
@GetMapping("/student/register")
public String register(Model model) {
model.addAttribute("student", new Student());
return "student/register";
}
@PostMapping("/student/save")
public String save(@ModelAttribute Student student) {
System.out.println("Aluno para salvar: " + student);
studentRepository.save(student);
return "redirect:/";
}
这是我的StudentRepository：
@Repository
public class StudentRepository {
public void save(Student student) {
Codec<Document> codec = MongoClient.getDefaultCodecRegistry().get(Document.class);
StudentCodec studentCodec = new StudentCodec(codec);
CodecRegistry registry = CodecRegistries.fromRegistries(MongoClient.getDefaultCodecRegistry(), CodecRegistries.fromCodecs(studentCodec));
MongoClientOptions options = MongoClientOptions.builder().codecRegistry(registry).build();
MongoClient mongoClient = new MongoClient("localhost:27017", options);
MongoDatabase database = mongoClient.getDatabase("test");
MongoCollection<Student> alunos = database.getCollection("alunos", Student.class);
alunos.insertOne(student);
mongoClient.close();
}
