Springboot获取前端反馈信息并存入数据库的实现代码

导入mybatis依赖

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

yml实现mybatis依赖

spring:
datasource:
 driver-class-name: com.mysql.cj.jdbc.Driver
 url: jdbc:mysql://localhost:3306/yanan_user #写自己的数据库名
 username: root
 password: 123456 #自己的账号密码
mybatis:
type-aliases-package: com.wjr.pojo
configuration:
 log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

编写前端代码

自行导入jQuery包，并调用

（form表单）

<form>
 <input type="text" name="name" placeholder="请输入您的姓名" required="">
 <input type="email" name="email" placeholder="请输入您的邮箱" required="">
 <input type="text" name="telephone" placeholder="请输入您的联系方式" required="">
 <textarea name="message" placeholder="请您提出您的宝贵建议，我们将认真阅读" required=""></textarea>
 <input class="btn1" type="button" value="提交" onclick="send(this.form)">
</form>

（ajax请求）

<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>

编写数据库信息

@Data //这里导入了lombok依赖
@Table(name = "feedback")
public class Feedback {
 @Id
 //主键回填
 @KeySql(useGeneratedKeys = true)
 private int id;
 private String name;
 private String email;
 private String telephone;
 private String message;
}

编写insert方法（mapper层接口）

@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);
}

编写接口（service层）

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

编写接口实现（serviceImpl层）

@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);
 }
}

接收信息并存入数据库（controller层）

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

注：一个简单的实现获取前端反馈信息存入数据库操作，自行尝试，如果有报错，请看注解是否正确，还可能存在各种版本问题；
