我试图在Spring中构建一个基本的CRUD应用程序。

创建一个模型类，如下所示：

Employee.java

import java.io.Serializable;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class Employee implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(nullable = false, updatable = false)
    private Long id;
    private String name;
    private String email;
    private String jobTitle;
    private String phone;
    private String imageUrl;
    @Column(nullable = false, updatable = false)
    private String employeeCode;

    public Employee() {
    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getJobTitle() {
        return jobTitle;
    }

    public void setJobTitle(String jobTitle) {
        this.jobTitle = jobTitle;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String getImageUrl() {
        return imageUrl;
    }

    public void setImageUrl(String imageUrl) {
        this.imageUrl = imageUrl;
    }

    public String getEmployeeCode() {
        return employeeCode;
    }

    public void setEmployeeCode(String employeeCode) {
        this.employeeCode = employeeCode;
    }

    public Employee(String name, String email, String jobTitle, String phone, String imageUrl, String employeeCode) {
        this.name = name;
        this.email = email;
        this.jobTitle = jobTitle;
        this.phone = phone;
        this.imageUrl = imageUrl;
        this.employeeCode = employeeCode;
    }

    @Override
    public String toString() {
        return "Employee [id=" + id + ", name=" + name + ", email=" + email + ", jobTitle=" + jobTitle + ", phone="
                + phone + ", imageUrl=" + imageUrl + ", employeeCode=" + employeeCode + "]";
    }

}

这是我的application.properties文件。

#MYSQL Configuration

spring.datasource.url=jdbc:mysql://localhost:3306/employeemanager
spring.datasource.data-username=myusername
spring.datasource.password=mypassword
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
debug= true

</project>

下面是错误的日志。
