Springboot獲取前端反饋信息並存入數據庫的實現代碼

導入mybatis依賴

<!--mybatis-->
<dependency>
  <groupId>org.mybatis.spring.boot</groupId>
  <artifactId>mybatis-spring-boot-starter</artifactId>
  <version>2.0.1</version>
</dependency>

yml實現mybatis依賴

spring:
 datasource:
  driver-class-name: com.mysql.cj.jdbc.Driver
  url: jdbc:mysql://localhost:3306/yanan_user #寫自己的數據庫名
  username: root
  password: 123456 #自己的賬號密碼
mybatis:
 type-aliases-package: com.wjr.pojo
 configuration:
  log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

編寫前端代碼

自行導入jQuery包,並調用

(form表單)

<form>
  <input type="text" name="name" placeholder="請輸入您的姓名" required="">
  <input type="email" name="email" placeholder="請輸入您的郵箱" required="">
  <input type="text" name="telephone" placeholder="請輸入您的聯系方式" required="">
  <textarea name="message" placeholder="請您提出您的寶貴建議,我們將認真閱讀" required=""></textarea>
  <input class="btn1" type="button" value="提交" onclick="send(this.form)">
</form>

(ajax請求)

<script>
    function send(fdform){
      alert(fdform);
      var fdj = {name:fdform.name.value,email:fdform.email.value,telephone:fdform.telephone.value,message:fdform.message.value};
      $.ajax({
        url:"jsonfb",
        data:fdj,
        contentType:"application/json",
        type:"GET"
      })
    }
</script>

編寫數據庫信息

@Data //這裡導入瞭lombok依賴
@Table(name = "feedback")
public class Feedback {
  @Id
  //主鍵回填
  @KeySql(useGeneratedKeys = true)
  private int id;
  private String name;
  private String email;
  private String telephone;
  private String message;
}

編寫insert方法(mapper層接口)

@Repository
public interface FeedbackMapper {
  @Insert({"insert into feedback(name,email,telephone,message) values('${feedback.name}','${feedback.email}','${feedback.telephone}','${feedback.message}')"})
  int add(@Param("feedback") Feedback feedback);
}

編寫接口(service層)

public interface FeedbackService {
  int addFeedback(String name, String email, String telephone,String message);
}

編寫接口實現(serviceImpl層)

@Service
public class FeedbackServiceImpl implements FeedbackService{
  @Autowired
  private FeedbackMapper feedbackMapper;
  @Override
  public int addFeedback(String name, String email, String telephone,String message){
    Feedback fb = new Feedback();
    fb.setName(name);
    fb.setMessage(message);
    fb.setTelephone(telephone);
    fb.setEmail(email);
    return feedbackMapper.add(fb);
  }
}

接收信息並存入數據庫(controller層)

@Autowired
  FeedbackServiceImpl feedbackServiceImpl;
  @RequestMapping(value = "/jsonfb") //和ajax請求中url相對應
  public String json(Feedback feedback){
    System.out.println(feedback);
    int f = feedbackServiceImpl.addFeedback(feedback.getName(), feedback.getEmail(), feedback.getTelephone(), feedback.getMessage());
    return "contact";
  }
