使用Lombok,是否可以指定一个arg构造函数?
我的目的是使用Lombok注释创建一个构造函数,如下所示.
- class MyClass {
- private String param;
- private Integer count;
- public MyClass(String param) {
- this.param = param;
- }
- }
解决方法
I didn’t find in documentation
怎么样:http://projectlombok.org/features/Constructor.html?
您必须初始化所有不应该是构造函数的变量.
@requiredArgsConstructor generates a constructor with 1 parameter for each field that requires special handling. All non-initialized final fields get a parameter,as well as any fields that are marked as @NonNull that aren’t initialized where they are declared. For those fields marked with @NonNull,an explicit null check is also generated.
所以下面应该创建一个参数(param)构造函数:
- @requiredArgsConstructor class MyClass {
- private String param;
- private Integer count = -1;
- }
