Golang 复制版 Copier
Copier 是 Golang 的复制版，它从一个结构复制到了另一个结构。它具有以下特点：
*
如果名字匹配，就从一个场景复制到另一个场景
*
如果方法名和场景名匹配，就从方法复制到场景
*
如果场景名和方法名匹配，就从场景复制到方法
*
从片复制到片
*
从结构复制到片
示例代码：
<pre class="brush:cpp ;toolbar: true; auto-links: false;">import . "github.com/jinzhu/copier"
type User struct {
Name string
Role string
Age int32}
func (user *User) DoubleAge() int32 {
return 2 * user.Age}
type Employee struct {
Name
string
Age int32
DoubleAge int32
EmployeId int64
SuperRule string}func (employee *Employee) Role(role string) {
employee.SuperRule = "Super " + role
}
user := User{Name: "Jinzhu", Age: 18, Role: "Admin"}
employee := Employee{}Copy(&employee, &user)
// employee => Employee{ Name: "Jinzhu",
// Copy from field
// Age: 18,
// Copy from field
// DoubleAge: 36,
// Copy from method
// EmployeeId: 0,
// Just ignored
// SuperRule: "Super Admin",
// Copy to method
// }
// Copy struct to slice
user := User{Name: "hello", Age: 18, Role: "User"}
employees := []Employee{}Copy(&employees, &user)
// employees => [{hello 18 0 36 Super User}]
// Copy slice to sliceusers := []User{{Name: "Jinzhu", Age: 18, Role: "Admin"}, {Name: "jinzhu 2", Age: 30, Role: "Dev"}}
employees := []Employee{}Copy(&employees, &users)
// employees => [{hello 18 0 36 Super User}
{Jinzhu 18 0 36 Super Admin} {jinzhu 2 30 0 60 Super Dev}]</pre>
