java - 通过启动 Spring Boot 应用程序在 H2 数据库中创建表

Question

启动 Spring Boot 应用程序时，未在 h2 中创建表

我创建了映射 mojo 类。在 application.properties 中添加了正确的条目。并且还启动了h2数据库。

pojo 类:

   package entities;

    import java.sql.Timestamp;

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

    @Entity
    public class links {
        @Id
        @GeneratedValue
        private Long userId;
        private String username;
        private String userAccountName;
        private String userPassword;
        private Integer age;
        private Timestamp setupTimestamp;
        private Integer weightInPounds;
        private Integer heightInCm;
        private String diet;
        private String intolerances;
        private Integer mealId;
        private Integer routineId;

        public links() {
            super();
        }
        public Long getUserId() {
            return userId;
        }
        public void setUserId(Long userId) {
            this.userId = userId;
        }
        public String getUsername() {
            return username;
        }
        public void setUsername(String username) {
            this.username = username;
        }
        public String getUserAccountName() {
            return userAccountName;
        }
        public void setUserAccountName(String userAccountName) {
            this.userAccountName = userAccountName;
        }
        public String getUserPassword() {
            return userPassword;
        }
        public void setUserPassword(String userPassword) {
            this.userPassword = userPassword;
        }
        public Integer getAge() {
            return age;
        }
        public void setAge(Integer age) {
            this.age = age;
        }
        public Timestamp getSetupTimestamp() {
            return setupTimestamp;
        }
        public void setSetupTimestamp(Timestamp setupTimestamp) {
            this.setupTimestamp = setupTimestamp;
        }
        public Integer getWeightInPounds() {
            return weightInPounds;
        }
        public void setWeightInPounds(Integer weightInPounds) {
            this.weightInPounds = weightInPounds;
        }
        public Integer getHeightInCm() {
            return heightInCm;
        }
        public void setHeightInCm(Integer heightInCm) {
            this.heightInCm = heightInCm;
        }
        public String getDiet() {
            return diet;
        }
        public void setDiet(String diet) {
            this.diet = diet;
        }
        public String getIntolerances() {
            return intolerances;
        }
        public void setIntolerances(String intolerances) {
            this.intolerances = intolerances;
        }
        public Integer getMealId() {
            return mealId;
        }
        public void setMealId(Integer mealId) {
            this.mealId = mealId;
        }
        public Integer getRoutineId() {
            return routineId;
        }
        public void setRoutineId(Integer routineId) {
            this.routineId = routineId;
        }
        @Override
        public String toString() {
            return "UserInfo [userId=" + userId + ", username=" + username + ", userAccountName=" + userAccountName
                    + ", userPassword=" + userPassword + ", age=" + age + ", setupTimestamp=" + setupTimestamp
                    + ", weightInPounds=" + weightInPounds + ", heightInCm=" + heightInCm + ", diet=" + diet
                    + ", intolerances=" + intolerances + ", mealId=" + mealId + ", routineId=" + routineId + "]";
        }



    }

应用程序属性

server.port=8090
spring.h2.console.enabled=true
spring.h2.console.path=/h2

H2 设置

Saved settings: Generic H2(Embedded)
Setting name: Generic H2(Embedded)
Driver Class: org.h2.driver
JDBC URL: jdbc:h2:mem:testdb
User Name: sa

应用程序正常启动，但表未创建。我在控制台中没有收到任何有关正在创建的表的消息。

我遇到了这个问题。问题在于文件夹结构。 Spring boot 无法映射实体类，因为应用程序启动时它们未包含在我的 basePackageClasses 映射中
