下面是配置信息：

spring.jpa:
    show-sql: true
    database: MYSQL
    properties.hibernate.dialect: org.hibernate.dialect.MySQL5Dialect
    hibernate:
      ddl-auto: update

    minIdle: 2
    test-on-borrow: false
    test-on-return: true
    test-while-idle: true

下面是實(shí)體類：

@Entity
@Table(name = "ssm_icon")
public class Icon {
    /**
     * 主鍵id
     */
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "id")
    private Long id;
    /**
     * 圖標(biāo)名稱
     */
    @Column(name = "icon_name")
    private String iconName;
    /**
     * 圖標(biāo)地址
     */
    @Column(name = "icon_address")
    private String iconAddress;
    /**
     * 圖標(biāo)編碼
     */
    @Column(name = "icon_code")
    private String iconCode;

    public Long getId() {
        return id;
    }

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

    public String getIconName() {
        return iconName;
    }

    public void setIconName(String iconName) {
        this.iconName = iconName;
    }

    public String getIconAddress() {
        return iconAddress;
    }

    public void setIconAddress(String iconAddress) {
        this.iconAddress = iconAddress;
    }

    public String getIconCode() {
        return iconCode;
    }

    public void setIconCode(String iconCode) {
        this.iconCode = iconCode;
    }
}

今天新建的一個(gè)srping boot項(xiàng)目無(wú)法jpa無(wú)法自動(dòng)生成數(shù)據(jù)庫(kù)表，把ddl-auto 換成create也不行，哪位大神可以幫忙看看是什么原因嗎
