如何使用JavaPoet构造具有自定义类型枚举

import com.squareup.javapoet.*;

public class EnumGenerator {
    public static void main(String[] args) {
        // 创建一个Java文件的构造器
        JavaFile javaFile = JavaFile.builder("com.example", generateEnum())
                .build();

        // 输出生成的Java文件
        try {
            javaFile.writeTo(System.out);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private static TypeSpec generateEnum() {
        // 创建一个枚举类型的构造器
        TypeSpec.Builder enumBuilder = TypeSpec.enumBuilder("MyEnum");

        // 添加枚举常量
        enumBuilder.addEnumConstant("VALUE1", TypeSpec.anonymousClassBuilder("$S", "Value 1").build());
        enumBuilder.addEnumConstant("VALUE2", TypeSpec.anonymousClassBuilder("$S", "Value 2").build());

        // 添加枚举方法
        MethodSpec method = MethodSpec.methodBuilder("getValue")
                .returns(String.class)
                .addStatement("return this.value")
                .build();
        enumBuilder.addMethod(method);

        // 添加枚举注解
        ClassName annotationClass = ClassName.get("com.example", "MyAnnotation");
        AnnotationSpec annotation = AnnotationSpec.builder(annotationClass)
                .addMember("value", "$S", "My Annotation")
                .build();
        enumBuilder.addAnnotation(annotation);

        return enumBuilder.build();
    }
}
