如何解决由于缺少列名而出现JDBI错误

我正在尝试使用jdbi将用户添加到MysqL数据库，但是当我尝试添加用户时，出现错误消息，提示我缺少列username

sql 

CREATE TABLE users
(
    id        int          NOT NULL AUTO_INCREMENT,username  varchar(100) NOT NULL,password  text         NOT NULL,email     varchar(150) NOT NULL,salt      text         NOT NULL,is_admin  boolean DEFAULT FALSE,is_active boolean DEFAULT TRUE,PRIMARY KEY (id),UNIQUE KEY username (username),UNIQUE KEY email (email)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8mb4;

是说我没有username列，但是我可以验证该列是否存在；

users table

我不确定我在做什么错。有什么想法吗？

修改 遵循@nbk的建议，我放下桌子并通过Workbench进行读取，但是这次我添加了反引号。这没什么！

sql 

CREATE TABLE users
(
    `id`        int          NOT NULL AUTO_INCREMENT,`username`  varchar(100) NOT NULL,`password`  text         NOT NULL,`email`     varchar(150) NOT NULL,`salt`      text         NOT NULL,`is_admin`  boolean DEFAULT FALSE,`is_active` boolean DEFAULT TRUE,PRIMARY KEY (`id`),UNIQUE KEY `username` (`username`),UNIQUE KEY `email` (`email`)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8mb4;

编辑＃2

包括端点和服务方法

UserResource 

@Path("/user")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public class UserResource {

    @Inject
    UserService userService;

    @POST
    public Response createNewRegularUser(@Valid UserEntity userEntity) {
        UserEntity user = userService.addRegularUser(userEntity);
        if (user != null) {
            return Response.ok(user).build();
        }
        return Response.noContent().build();
    }

}

UserService 

@ApplicationScoped
public class UserService {

    @Inject
    jdbiProvider dbi;

    public UserEntity addRegularUser(UserEntity user) {
        return dbi.get().inTransaction(handle -> {
            hashPassword(user);
            LOGGER.info("Hashed password for user {} and adding as user",user.getEmail());
            return handle.attach(UserEntity.DAO.class)
                    .addUser(user.getUsername(),user.getpassword(),user.getEmail(),user.getSalt());
        });
    }

}

注意：仅包括必要的方法，以免使问题超载

解决方法

我决定将数据库从MySQL更改为PostgreSQL，因为MySQL的docker容器启动时间太长。这样，我更新了我的应用程序文件pom.xml，然后更新了sql文件以修复语法。当我运行应用程序并决定添加一个用户（不更改任何代码）并将该用户添加到数据库中时，我感到很幸运，我得到了邮差的回复

在我看来这是一个MySQL问题，当我换成Postgres时，这个问题就消失了
