Question

在我目前的项目中，我有这段代码：

    for(Annotation annotation : field.getAnnotations()) {
      String package = annotation.annotationType().getPackage().getName();
      if(package.equals("com.loja.annotations.input_type"))
        input.setAttribute("type", annotation.annotationType().getSimpleName());
    }

当我尝试构建项目时，由于此错误，此代码导致编译失败：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project store: Compilation failure: Compilation failure:
[ERROR] /c:/Users/Kleber Mota/Documents/GitHub/app/src/main/java/com/loja/thymeleaf/processor/form/InputProcessor.java:[37,11] not a statement

[ERROR] /c:/Users/Kleber Mota/Documents/GitHub/app/src/main/java/com/loja/thymeleaf/processor/form/InputProcessor.java:[38,22] variable declaration not allowed here

任何人都可以看到这里有什么问题？

第37行是：String package = annotation.annotationType().getPackage().getName();，第38行是if(package.equals("com.loja.annotations.input_type"))

Answer 1

你可以试试这个..

annotation.annotationType().getName();

Answer 2

您可以在第37行（之前的if）之后打印出“package”变量。我编写并运行了类似的代码，它对我有用。我在api包中创建了一个自定义注释，第37行返回“api”。

从类变量中尝试提取包名称时出错
