Question

我有一个简单的服务器，该服务器应具有与数据库一起使用的POST，PUT和GET方法。我有一个应用程序，在这里我使用Retrofit2，在我使用GET调用时-没关系，我可以从数据库中获取数据。但是，当我尝试使用POST或PUT创建新数据或更新数据库时，我的服务器没有收到来自应用程序的任何调用。请向我解释我错了。

RemindController.java：

@RestController
public class ReminderController {

@Autowired
private RemindRepository repository;

@RequestMapping(value = "/profile", method = RequestMethod.GET)
@ResponseBody
public List<Profile> getAllProfiles(  ){
    return repository.findAll();
}

@RequestMapping(value = "/profile/{id}", method = RequestMethod.GET)
@ResponseBody
public Profile getProfile(@PathVariable("id") long profileID){
    return repository.findById(profileID).get();
}

@RequestMapping(value = "/profile", method = RequestMethod.POST)
@ResponseBody
public Profile saveProfile(@RequestBody Profile profile){
    return repository.saveAndFlush(profile);
}

@RequestMapping(value = "/profile/{id}", method = RequestMethod.PUT)
@ResponseBody
public Profile putProfile(@PathVariable("id") long id, @RequestParam String name, @RequestParam String address){
    Profile profile = repository.findById(id).get();
    profile.setCourier_name(name);
    profile.setAddress(address);
    repository.save(profile);
    return profile;
}
}

实体类：

@Entity
@Table(name = "profile")
public class Profile {

@Id
@GeneratedValue(generator = "increment")
@GenericGenerator(name = "increment", strategy = "increment")
private long id;

@Column(name = "courier_name", nullable = false, length = 50)
private String courier_name;

@Column(name = "address", nullable = false, length = 100)
private String address;

@Column(name = "number", nullable = false, length = 10)
private String number;

@Column(name = "info", nullable = false, length = 100)
private String info;

public Profile() {
}

public long getId() {
    return id;
}

public void setId(long id) {
    this.id = id;
}

public String getCourier_name() {
    return courier_name;
}

public void setCourier_name(String courier_name) {
    this.courier_name = courier_name;
}

public String getAddress() {
    return address;
}

public void setAddress(String address) {
    this.address = address;
}

public String getNumber() {
    return number;
}

public void setNumber(String number) {
    this.number = number;
}

public String getInfo() {
    return info;
}

public void setInfo(String info) {
    this.info = info;
}

我拨打电话的代码（POST / PUT）：

     ...
     ...
     Retrofit retrofit = new Retrofit.Builder()
            .baseUrl("http://192.168.1.2:8080/")
            .addConverterFactory(GsonConverterFactory.create())
            .build();

    jsonPlaceHolderApi = retrofit.create(JsonPlaceHolderApi.class);

    mSaveProfile = findViewById(R.id.save_data_profile);
    mSaveProfile.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            makeCallPost();
          //  makeCallPut();
        }
    });

   // makeCallGet();

}


    public void makeCallPut(){

    Call<GetAndSetProfile> call = jsonPlaceHolderApi.putProfile(1, "Someone", "Berlin");

    call.enqueue(new Callback<GetAndSetProfile>() {
        @Override
        public void onResponse(Call<GetAndSetProfile> call, Response<GetAndSetProfile> response) {
            if (!response.isSuccessful()){
                Toast toast = Toast.makeText(getApplicationContext(),
                        "Error 404", Toast.LENGTH_LONG);
                toast.show();
            }
        }

        @Override
        public void onFailure(Call<GetAndSetProfile> call, Throwable t) {
            mName.setText(t.getMessage());
            Toast toast = Toast.makeText(getApplicationContext(),
                    "Error", Toast.LENGTH_LONG);
            toast.show();
        }
    });

}

public void makeCallPost(){

    GetAndSetProfile getAndSetProfile = new GetAndSetProfile(1, mProfile.getName(), mProfile.getAddress(),
            mProfile.getNumber(), mProfile.getInfo());

    Call<GetAndSetProfile> call = jsonPlaceHolderApi.saveProfile(getAndSetProfile);

    call.enqueue(new Callback<GetAndSetProfile>() {
        @Override
        public void onResponse(Call<GetAndSetProfile> call, Response<GetAndSetProfile> response) {
            if (!response.isSuccessful()){

                Toast toast = Toast.makeText(getApplicationContext(),
                        "Error 404", Toast.LENGTH_LONG);
                toast.show();
            }


            Toast toast = Toast.makeText(getApplicationContext(),
                    "Saved", Toast.LENGTH_LONG);
            toast.show();
            return;
        }

        @Override
        public void onFailure(Call<GetAndSetProfile> call, Throwable t) {
            mName.setText(t.getMessage());
            Toast toast = Toast.makeText(getApplicationContext(),
                    "Error", Toast.LENGTH_LONG);
            toast.show();
        }
    });

}

GetAndSetProfile.java

public class GetAndSetProfile {

@SerializedName("increment")
private long id;
private String courier_name;
private String address;
private String number;
private String info;

public GetAndSetProfile(long id, String courier_name, String address, String number, String info) {
    this.id = id;
    this.courier_name = courier_name;
    this.address = address;
    this.number = number;
    this.info = info;
}

public long getId() {
    return id;
}

public void setId(long id) {
    this.id = id;
}

public String getCourier_name() {
    return courier_name;
}

public void setCourier_name(String courier_name) {
    this.courier_name = courier_name;
}

public String getAddress() {
    return address;
}

public void setAddress(String address) {
    this.address = address;
}

public String getNumber() {
    return number;
}

public void setNumber(String number) {
    this.number = number;
}

public String getInfo() {
    return info;
}

public void setInfo(String info) {
    this.info = info;
}

JsonPlaceHolderApi.java

public interface JsonPlaceHolderApi {

@GET("profile/{id}")
Call<GetAndSetProfile> getAllProfiles(@Path("id") long id);

@POST("profile")
Call<GetAndSetProfile> saveProfile(@Body GetAndSetProfile getAndSetProfile);

@FormUrlEncoded
@PUT("profile/{id}")
Call<GetAndSetProfile> putProfile(@Path("id") long id, @Field("name") String name, @Field("address") String address);

 }

如何使服务器处理POST和Put呼叫？我已经学习编程仅两个星期了，我不了解很多事情。所有这些代码，我都来自不同的资源，并不完全理解。希望得到您的帮助，并先谢谢您。
