Spring实战运行第六章代码笔记（1）

Taco类中有Ingredient相关字段：

 @ManyToMany(targetEntity=Ingredient.class)
  @Size(min=1, message="You must choose at least 1 ingredient")
  private List ingredients;

依据Taco_Ingredients表进行连表查询：

但是问题在于hibernate在连表查询时，默认join table中的字段为taco_id和ingredient_id，这与实际join table中的column名称不符合。

@ManyToMany(targetEntity=Ingredient.class)
  @Size(min=1, message="You must choose at least 1 ingredient")
  @JoinTable(name = "Taco_Ingredients",
          joinColumns = @JoinColumn(name = "taco"),
          inverseJoinColumns = @JoinColumn(name = "ingredient"))
  private List ingredients;

因为hibernate默认将枚举类型字段的EnumType设置为EnumType.ORDINAL

显然，从mysql中获取到的type为string类型，无法转换为序数

  @Enumerated(EnumType.STRING)
  private final Type type;
