Android使用OKhttp3实现登录注册功能+springboot搭建后端的详细过程

Android使⽤OKhttp3实现登录注册功能+springboot搭建后端的详细过程⽬录

⼀、Android前端实现

⼆、数据库

三、SpringBoot后端搭建

四、部署⾄服务器

五、运⾏测试

⼀、Android前端实现

新建⼀个login的项⽬，主要的⼏个⽂件在这⾥

1、gradle引⼊OKhttp3依赖

implementation 'com.squareup.okhttp3:okhttp:3.14.7'

implementation 'com.squareup.okio:okio:1.17.5'

2、l布局⽂件

<?xml version="1.0" encoding="utf-8"?>

&straintlayout.widget.ConstraintLayout xmlns:android="schemas.android/apk/res/android"

xmlns:app="schemas.android/apk/res-auto"

xmlns:tools="schemas.android/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

tools:context=".MainActivity">

<EditText

android:id="@+id/username"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:hint="⽤户名"

android:textSize="34sp"

app:layout_constraintBottom_toBottomOf="parent"

app:layout_constraintEnd_toEndOf="parent"

app:layout_constraintStart_toStartOf="parent"

app:layout_constraintTop_toTopOf="parent"

app:layout_constraintVertical_bias="0.051" />

<EditText

android:id="@+id/password"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:hint="密码"

android:textSize="34sp"

app:layout_constraintBottom_toBottomOf="parent"

app:layout_constraintEnd_toEndOf="parent"

app:layout_constraintStart_toStartOf="parent"

app:layout_constraintTop_toBottomOf="@+id/username"

app:layout_constraintVertical_bias="0.067" />

<Button

android:id="@+id/button"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:onClick="register"

android:text="注册"

android:textSize="24sp"

app:backgroundTint="#E91E63"

app:layout_constraintBottom_toBottomOf="parent"

app:layout_constraintEnd_toEndOf="parent"

app:layout_constraintHorizontal_bias="0.501"

app:layout_constraintStart_toStartOf="parent"

app:layout_constraintTop_toBottomOf="@+id/password"

app:layout_constraintVertical_bias="0.058" />

<Button

android:id="@+id/getUser"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:onClick="getUser"

android:text="获取"

android:textSize="24sp"

app:backgroundTint="#E91E63"

app:layout_constraintBottom_toBottomOf="parent"

app:layout_constraintEnd_toEndOf="parent"

app:layout_constraintHorizontal_bias="0.501"

app:layout_constraintStart_toStartOf="parent"

app:layout_constraintTop_toBottomOf="@+id/button3"

app:layout_constraintVertical_bias="0.174" />

<Button

android:id="@+id/button3"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="登录"

android:textSize="24sp"

app:backgroundTint="#E91E63"

android:onClick="login"

app:layout_constraintBottom_toBottomOf="parent"

app:layout_constraintEnd_toEndOf="parent"

app:layout_constraintHorizontal_bias="0.501"

app:layout_constraintStart_toStartOf="parent"

app:layout_constraintTop_toBottomOf="@+id/button"

app:layout_constraintVertical_bias="0.113" />

</straintlayout.widget.ConstraintLayout>

3、l配置⽂件

这⾥需要加上⽹络请求权限，添加⽹络权限的时候注意：在res⽬录下新建xml⽬录，创建network_l⽂件

<?xml version="1.0" encoding="utf-8"?>

<network-security-config>

<base-config cleartextTrafficPermitted="true" />

</network-security-config>

并在配置⽂件中加⼊这⾏代码：

android:networkSecurityConfig="@xml/network_security_config"

完整的l⽂件如下

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="schemas.android/apk/res/android"

package="ample.login">

<uses-permission android:name="android.permission.INTERNET"/>

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

<application

android:allowBackup="true"

android:icon="@mipmap/ic_launcher"

android:label="@string/app_name"

android:roundIcon="@mipmap/ic_launcher_round"

android:networkSecurityConfig="@xml/network_security_config"

android:supportsRtl="true"

android:theme="@style/Theme.Login">

<intent-filter>

</intent-filter>

</activity>

</application>

</manifest>

4、创建User实体类

新建entity⽬录创建User实体类。注意这⾥我是根据后端数据库的字段创建的，在实现登录注册的时候只需要id,username,password ⼏个基础的字段就⾏，这⾥我⽐较多，读者可以⾃⾏忽略。User.java

ity;

public class User {

private Integer userId;

private String userName;

private String userPassword;

private String currentVersion;

private String latestVersion;

private String updateDescription;

private String headPortrait;

private String nickName;

private String vipTime;

private String userCategory;

private String registerDate;

public User(Integer userId, String userName, String userPassword, String currentVersion, String latestVersion, String updateDescription, String headPortrait, String nickName, String vipTime, String userCategory, String registerDate) { this.userId = userId;

this.userName = userName;

this.userPassword = userPassword;

this.currentVersion = currentVersion;

this.latestVersion = latestVersion;

this.updateDescription = updateDescription;

this.headPortrait = headPortrait;

this.nickName = nickName;

this.vipTime = vipTime;

this.userCategory = userCategory;

}

public User() {

}

public Integer getUserId() {

return userId;

}

public void setUserId(Integer userId) {

this.userId = userId;

}

public String getUserName() {

return userName;

}

public void setUserName(String userName) {

this.userName = userName;

}

public String getUserPassword() {

return userPassword;

}

public void setUserPassword(String userPassword) {

this.userPassword = userPassword;

}

public String getCurrentVersion() {

return currentVersion;

}

public void setCurrentVersion(String currentVersion) {

this.currentVersion = currentVersion;

}

public String getLatestVersion() {

return latestVersion;

}

public void setLatestVersion(String latestVersion) {

this.latestVersion = latestVersion;

}

public String getUpdateDescription() {

return updateDescription;

}

public void setUpdateDescription(String updateDescription) { this.updateDescription = updateDescription;

}

public String getHeadPortrait() {

return headPortrait;

}

public void setHeadPortrait(String headPortrait) {

this.headPortrait = headPortrait;

}

public String getNickName() {

return nickName;

}

public void setNickName(String nickName) {

this.nickName = nickName;

}

public String getVipTime() {

return vipTime;

}

public void setVipTime(String vipTime) {

this.vipTime = vipTime;

}

public String getUserCategory() {

return userCategory;

}

public void setUserCategory(String userCategory) {

this.userCategory = userCategory;

}

public String getRegisterDate() {

return registerDate;

}

public void setRegisterDate(String registerDate) {

}

LoginUser.java

public class LoginUser {

private String userName;

private String userPassword;

public LoginUser(String userName, String userPassword) { this.userName = userName;

this.userPassword = userPassword;

}

public LoginUser() {

}

public String getUserName() {

return userName;

}

public void setUserName(String userName) {

this.userName = userName;

}

安卓intent用法

public String getUserPassword() {

return userPassword;

}

public void setUserPassword(String userPassword) {

this.userPassword = userPassword;

}

5、MainActivity.java

ample.login;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;

import android.util.Log;

import android.view.View;

import android.widget.EditText;

import android.widget.TextView;

import android.widget.Toast;

ity.User;

import org.json.JSONException;

import org.json.JSONObject;

import java.io.IOException;

import okhttp3.Call;

import okhttp3.Callback;

import okhttp3.MediaType;

import okhttp3.OkHttpClient;

import okhttp3.Request;

import okhttp3.RequestBody;

import okhttp3.Response;

public class MainActivity extends AppCompatActivity {

private EditText username;

private EditText password;

private User user;

@Override

protected void onCreate(Bundle savedInstanceState) {

setContentView(R.layout.activity_main);

username = findViewById(R.id.username);

password = findViewById(R.id.password);

}

public void register(View view) {

user = new User();

user.Text().toString());

Log.d("whqusername",Text().toString());

Log.d("whqpassword",Text().toString());

new Thread(new Runnable() {

@Override

public void run() {

MediaType JSON = MediaType.parse("application/json;charset=utf-8");

JSONObject jsonObject = new JSONObject();

OkHttpClient httpClient = new OkHttpClient();

try {

jsonObject.put("userId",10);

jsonObject.put("userName",UserName());

jsonObject.put("userPassword",UserPassword());

jsonObject.put("currentVersion",null);

jsonObject.put("latestVersion",null);

jsonObject.put("updateDescription",null);

jsonObject.put("headPortrait",null);

jsonObject.put("nickName",UserName());

jsonObject.put("vipTime",null);

jsonObject.put("userCategory",null);

jsonObject.put("registerDate",null);

} catch (JSONException e) {

e.printStackTrace();

}

RequestBody requestBody = ate(JSON, String.valueOf(jsonObject)); String url = "ip:8001/server/user/addUser/";

Request request = new Request.Builder()

.url(url)

.post(requestBody)

.build();

Call call = wCall(request);

@Override

public void onFailure(Call call, IOException e) {

Log.d("whq","失败了");

}

@Override

public void onResponse(Call call, Response response) throws IOException {

Log.d("whq",String()+"------------------");

Log.d("whq",response.body().toString()+"------------------");

}

});

}

}).start();

}

public void getUser(View view) {

OkHttpClient httpClient = new OkHttpClient();

String url = "ip:8001/server/user/getAllUserName";

Request getRequest = new Request.Builder()

.url(url)

get()

.build();

Call call = wCall(getRequest);

new Thread(new Runnable() {

@Override

public void run() {

try {

//同步请求，要放到⼦线程执⾏

Response response = ute();

Log.i("whq+getAllUserName", "okHttpGet run: response:"+ response.body().string()); } catch (IOException e) {

e.printStackTrace();

}

}).start();

}

public void login(View view) {

loginUser = new LoginUser();

loginUser.Text().toString());

new Thread(new Runnable() {

@Override

public void run() {

MediaType JSON = MediaType.parse("application/json;charset=utf-8");

JSONObject jsonObject = new JSONObject();

OkHttpClient httpClient = new OkHttpClient();

try {

jsonObject.put("userName",UserName());

jsonObject.put("userPassword",UserPassword()));

} catch (JSONException e) {

e.printStackTrace();

}

RequestBody requestBody = ate(JSON, String.valueOf(jsonObject)); String url = "ip:8001/server/user/login";

Request request = new Request.Builder()

.url(url)

.post(requestBody)

.build();

Call call = wCall(request);

@Override

public void onFailure(Call call, IOException e) {

Log.d("whq登录","失败了");

}

@Override

public void onResponse(Call call, Response response) throws IOException {

String MyResult = response.body().string();

Log.d("whq登录",response+"---------response---------");

Log.d("whq登录",ssage()+"---------message---------");

Log.d("whq登录",response.body().toString()+"------------------");

Log.d("whq登录",MyResult+"-----------MyResult-------");

}

});

}

}).start();

}

到这⾥就实现了Android的前端实现。

⼆、数据库

数据库就是简单的⼀个user表

SET NAMES utf8mb4;

SET FOREIGN_KEY_CHECKS = 0;

-- ----------------------------

-- Table structure for user

-- ----------------------------

DROP TABLE IF EXISTS `user`;

CREATE TABLE `user` (

`userId` int(11) NOT NULL AUTO_INCREMENT,

`userName` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,

`userPassword` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,

`currentVersion` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,

`latestVersion` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,

`updateDescription` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,

`headPortrait` mediumblob NULL,

`nickName` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,

`vipTime` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,

`userCategory` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT 'normal',

`registerDate` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,

PRIMARY KEY (`userId`, `userName`) USING BTREE

) ENGINE = InnoDB AUTO_INCREMENT = 13 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = DYNAMIC; SET FOREIGN_KEY_CHECKS = 1;

三、SpringBoot后端搭建

后端搭建⽤到的是SSM框架

1、新建⼀个springboot项⽬，添加依赖

<java.version>1.8</java.version>

<mybatis-plus.version>3.0.5</mybatis-plus.version>

<swagger.version>2.7.0</swagger.version>

<jodatime.version>2.10.1</jodatime.version>

<poi.version>3.17</poi.version>
