我创建了一个动态Web项目,但我无法将其部署到Apache Tomcat Server 6.0中.我尝试部署项目时遇到此错误:

没有可以从服务器添加或删除的资源.

为什么POJO Java类必须实现Serializable接口？如果我不执行Serializable会怎么样？

@Entity
@Table(name="Customer")
public class Customer implements Serializable {

    private static final long serialVersionUID = -5294188737237640015L;
    /**
     * Holds Customer id of the customer
     */
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "cust_id")
    private int Custid;

    /** Holds first Name of the customer*/
    @Column(name = "first_name")
    private String firstName;

    /** Holds last Name of the customer */
    @Column(name = "last_name")
    private String lastName;

    /** Holds Customer mobile number of customer*/
    @Column(name = "cust_mobile")
    private long MobileNo; …

无法启动应用程序，使此消息出现以下异常。

尝试升级Java和Spring Boot父启动器时

pom.xml已升级了Spring Boot父启动器和Java

我是否需要为此添加任何其他Maven依赖项？

尝试添加spring-integration-core依赖性会导致不同的异常。
