Springboot获取前端反馈信息并存入数据库的实现代码

时间:2021-05-20

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)

@Repositorypublic 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)

@Servicepublic 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;
