mysql - Spring Boot 和数据库初始化 - 找不到 data.sql

问题描述

我正在设置一个 ** REST-API **，并且想在执行时启动 spring-boot 服务器时填充我的数据库（MySQL）。

我一直在研究箭头，发现有一种方法可以通过在资源文件夹中添加一个 data.sql 文件来做到这一点。

执行 que 数据操作，我发现有 2 种可能的方法

休眠支持

通过在属性文件中添加下一行 spring.jpa.properties.hibernate.hbm2ddl.import_files=data.sql

Spring JDBC 支持

通过在属性文件中添加下一行 spring.datasource.data=data.sql

用户实体

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

    /**
     *
     */
    private static final long serialVersionUID = 1L;

    @Id
    @Column(name = "id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    @NotNull(message = "FirstName cannot be null")
    @Column(name = "first_Name", length = 10)
    private String firstName;
    @NotNull(message = "LastName cannot be null")
    @Column(name = "last_Name", length = 20)
    private String lastName;
    @Email(message = "Email should be valid")
    private String email;
    @JsonProperty(access = Access.WRITE_ONLY)
    @Column(name = "pas")
    @Min(value = 8, message = "Password should not be less than 8")
    @NotNull
    private String pas;
    @JsonIgnore
    @Column(name = "enabled")
    private boolean enabled;
    @JsonIgnore
    @Column(name = "token_Expired")
    private boolean tokenExpired;
    @Column(name = "local_date_time", columnDefinition = "TIMESTAMP")
    private LocalDateTime localDateTime;


  //Getters Setters

我得到这个例外的第一个选项

spring.jpa.properties.hibernate.hbm2ddl.import_files=data.sql

我的陈述中似乎有一个 sintax 错误

insert into users(email, enabled, first_name, last_name, local_date_time, pas, token_expired)
values ('juan@email.com',false,'Juan','Lopez',curdate(),'pasword1',false);

第二个选项我得到了这个例外。

好像spring找不到data.sql文件

应用程序属性

 spring.jpa.hibernate.ddl-auto=create-drop
 spring.datasource.url=jdbc:mysql://localhost:3306/manager
 spring.datasource.username=root
 spring.datasource.password=
 spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
 spring.jpa.properties.hibernate.dialect =  org.hibernate.dialect.MySQL5Dialect
 spring.jpa.show-sql=true
 spring.datasource.data=data.sql
 spring.datasource.initialization-mode=always

感谢您的任何建议

解决方案

您可以尝试告诉 Spring 在类路径中显式查找文件：

spring.datasource.data=classpath:data.sql
