Go语言建造者模式：复杂对象构建

Go语言建造者模式：复杂对象构建

1. 建造者实现

type User struct { Name string Age int Email string Phone string Address string } type UserBuilder struct { user *User } func NewUserBuilder() *UserBuilder { return &UserBuilder{user: &User{}} } func (b *UserBuilder) Name(name string) *UserBuilder { b.user.Name = name return b } func (b *UserBuilder) Age(age int) *UserBuilder { b.user.Age = age return b } func (b *UserBuilder) Email(email string) *UserBuilder { b.user.Email = email return b } func (b *UserBuilder) Build() *User { return b.user }

2. 总结

建造者模式适合构建复杂对象，通过链式调用提供流畅的API。
