android - 发现两个 getter 或属性的大小写敏感度冲突的字段

Question

任何人都可以检查它是否有错误，因为我总是出错

com.google.firebase.database.DatabaseException: Found two getters or fields with conflicting case sensitivity for property.

这是我的代码 signupTeacherActivity:

public class signupTeacher extends AppCompatActivity {
EditText userfirstname,userlastname, useremail,userpassword,userconfirmpassword, CV,city;
private DatabaseReference mDatabase;
private FirebaseAuth mAuth;
Spinner spinner;
String defaultuserprofileimg;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_signup_teacher);
    getSupportActionBar().setTitle("Sign Up");
    findViewByIds();

    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.subject_array, android.R.layout.simple_spinner_item);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(adapter);
}

public void signUpUser(View view) {
    if(useremail.getText().toString().length()==0 || userpassword.getText().toString().length()==0||userfirstname.getText().length()==0 ||userconfirmpassword.getText().length()==0 ||userlastname.getText().length()==0){
        Toast.makeText(signupTeacher.this, "Please enter all the fields to proceed further.",
                Toast.LENGTH_SHORT).show();
    }else {
        if(spinner.getSelectedItem().toString().equals("Select a Subject")){
            Toast.makeText(signupTeacher.this, "Please select a valid Subject.", Toast.LENGTH_LONG).show();
        }
        else {
            mAuth = FirebaseAuth.getInstance();
            mAuth.createUserWithEmailAndPassword(useremail.getText().toString(), userpassword.getText().toString())
                    .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                        @Override
                        public void onComplete(@NonNull Task<AuthResult> task) {
                            Log.d("demo", "createUserWithEmail:onComplete:" + task.isSuccessful());

                            if (!task.isSuccessful()) {
                                Toast.makeText(signupTeacher.this, task.getException().toString(),
                                        Toast.LENGTH_SHORT).show();
                            } else {
                                mDatabase = FirebaseDatabase.getInstance().getReference();
                                Teacher user = new Teacher(userfirstname.getText().toString(), userlastname.getText().toString(), useremail.getText().toString(), userpassword.getText().toString() , CV.getText().toString(), spinner.getSelectedItem().toString(), city.getText().toString(),task.getResult().getUser().getUid().toString(), defaultuserprofileimg);
                                mDatabase.child("Teachers").child(task.getResult().getUser().getUid().toString()).setValue(user);
                                Intent i = new Intent(signupTeacher.this, MainActivity.class);
                                startActivity(i);
                                Toast.makeText(signupTeacher.this, "Succesfully registered. Please login with the created credentials",
                                        Toast.LENGTH_LONG).show();
                                mAuth = FirebaseAuth.getInstance();
                                mAuth.signOut();
                                finish();
                            }

                        }

                    });
        }

感谢您的帮助!

Answer 1

尝试固定您的字段和方法的大写。 firstName, getFirstName...等

您的错误在 CV 字段上，该方法应该是 setCV 以匹配该字段的大小写，但是，您应该将其命名为 cv 遵循 Java 命名争用。然后方法是 get 或 setCv

public String getCv() {
    return cv;
}

public void setCv(String cv) {
    this.cv = cv;
 }

我还建议不要将密码存储为对象的一部分。特别是如果它们是纯文本。您将密码发送到数据库以检查有效性或更新；读出它们并在别处坚持它们很少是一个好主意
