问答 @Table自动建表的问题
发布于 2351天前 作者 Zhouwt998 3780 次浏览 复制 上一个帖子 下一个帖子
标签:
@Table("user")
public class User {

这样没有自动建表

@Table("use")
public class User {

随便换一个名字就自动建了,这是什么问题。

没有建表只能是表已经存在.

没有建表的痕迹,数据库里面也没有

这个就有了,好奇怪啊~~

不要用test数据库

贴代码看看

# -Spring Datasource- #

    driver-class-name: org.postgresql.Driver
    url: jdbc:postgresql://localhost:5432/student?useUnicode=true&characterEncoding=UTF-8&useSSL=false

    private String passWord;

    public Integer getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

    public void setName(String name) {

    }

    public String getUserName() {

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassWord() {
        return passWord;
    }

    public void setPassWord(String passWord) {
        this.passWord = passWord;
    }
}

没有这句日志?这个日志应该跟@Table无关的

忘记截日志了,您看一下,是有那句日志的

但为什么我只有一个实体,他Found 2 resource?

Found 2 resources 并非指实体数量, 只是说这个目录下有多少个文件

自行调用一下 dao.create(User.class, false) 试试

自行调用也不行,算了,不纠结了,主要换个名字就行,这就很奇怪。谢谢您~
