1. 创建springboot基础环境
根据自己自定义项目名称一路next即可
数据源配置
#通用数据源配置
spring.jpa.hibernate.ddl-auto=create
#spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/test?charset=utf8mb4&useSSL=false
spring.datasource.username=root
spring.datasource.password=root
2. 实体类，注意包一定要导对
package com.cx.springtransaction.domain;
import javax.persistence.*;
@Entity
@Table(name = "auth_user_t")
public class User {
@Id
@GeneratedValue(strategy= GenerationType.AUTO)
private Long id;
@Column(length = 32)
private String username;
@Column(length = 32)
private String amount;
@Column(length = 64)
private String password;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getAmount() {
return amount;
}
public void setAmount(String amount) {
this.amount = amount;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
3. 数据访问层
package com.cx.springtransaction.dao;
import com.cx.springtransaction.domain.User;
import org.springframework.data.jpa.repository.JpaRepository;
public interface UserRepository extends JpaRepository<User, Long> {
}
