在Spring Boot 中,实现生成器模式的最佳写法是:

创建一个Builder类静态内部类,该类包含所有需要构建的属性,并提供setter方法来设置这些属性。

2. 在Builder类中创建一个build方法静态内部类,该方法将使用Builder类的属性创建并返回一个新的对象。

3. 在Spring Boot中,可以将Builder类作为静态内部类添加到要构建的类中,以便更好地组织代码

以下是示例代码:

public class Person {   private final String name;   private final int age;   private final String address;   private final String phone;      private Person(Builder builder) {       this.name = builder.name;       this.age = builder.age;       this.address = builder.address;       this.phone = builder.phone;   }      public String getName() {       return name;   }      public int getAge() {       return age;   }      public String getAddress() {       return address;   }      public String getPhone() {       return phone;   }      public static class Builder {       private String name;       private int age;       private String address;       private String phone;              public Builder name(String name) {           this.name = name;           return this;       }              public Builder age(int age) {           this.age = age;           return this;       }              public Builder address(String address) {           this.address = address;           return this;       }              public Builder phone(String phone) {           this.phone = phone;           return this;       }              public Person build() {           return new Person(this);       }   }}

现在,您可以使用以下代码创建Person对象:

Person person = new Person.Builder()                .name("John")                .age(25)                .address("123 Main St")                .phone("555-555-5555")                .build();

上文描述了如何逐步的构建一个复杂对象,在springboot日常使用中,可以采用lombok库的@Builder注解来便捷实现。
