@ManyToMany(fetch = FetchType.LAZY)
@JoinTable(name = "theme_spu", joinColumns = @JoinColumn(name = "theme_id"),
inverseJoinColumns = @JoinColumn(name = "spu_id"))
private List<Spu> spuList;

Table [theme_spu] contains physical column name [theme_id] referred to by multiple logical column names: [theme_id], [themeId]

改成驼峰后可以正常启动了，但是我发现和老师的不一样， 是我配置的有问题吗

@ManyToMany(fetch = FetchType.LAZY)
@JoinTable(name = "theme_spu", joinColumns = @JoinColumn(name = "themeId"),
inverseJoinColumns = @JoinColumn(name = "spuId"))
private List<Spu> spuList;

最后我发现表名也可以改成驼峰,也可以正常启动

@ManyToMany(fetch = FetchType.LAZY)
@JoinTable(name = "themeSpu", joinColumns = @JoinColumn(name = "themeId"),
inverseJoinColumns = @JoinColumn(name = "spuId"))
private List<Spu> spuList;
