我正在使用JavaPoet编写代码生成器,并且需要在类上添加注释
例如 :
package some.package
import org.hibernate.annotations.CacheConcurrencyStrategy;
import javax.persistence.Entity;
import javax.persistence.Cache
@Entity
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
public class SomeClass {
}
我的代码如下所示:
TypeSpec spec = TypeSpec
.classBuilder("SomeClass")
.addAnnotation(Entity.class)
.addAnnotation(AnnotationSpec.builder(Cache.class)
.addMember("usage", "$L", CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
.build())
.build()
这段代码生成了该类,但是结果代码缺少CacheConcurrencyStrategy的import语句。
如何生成代码,以便输出所有必需的代码?
最佳答案
试试这个:
TypeSpec spec = TypeSpec
.classBuilder("SomeClass")
.addAnnotation(Entity.class)
.addAnnotation(AnnotationSpec.builder(Cache.class)
.addMember("usage", "$T.$L", CacheConcurrencyStrategy.class,
CacheConcurrencyStrategy.NONSTRICT_READ_WRITE.name())
.build())
.build()
$T
标识枚举类,$L
标识枚举常量。
