如何将@RequestBody映射到实现Builder模式的Java对象

public class User {
    private String name;
    private int age;
    // 其他属性...

    private User(Builder builder) {
        this.name = builder.name;
        this.age = builder.age;
        // 其他属性...
    }

    // Getter方法...

    public static class Builder {
        private String name;
        private int age;
        // 其他属性...

        public Builder name(String name) {
            this.name = name;
            return this;
        }

        public Builder age(int age) {
            this.age = age;
            return this;
        }

        // 其他setter方法...

        public User build() {
            return new User(this);
        }
    }
}

@PostMapping("/user")
public void createUser(@RequestBody User.Builder userBuilder) {
    User user = userBuilder.build();
    // 处理用户创建逻辑...
}
