java - 尝试从类变量中提取包名称时出错

Question

在我当前的项目中，我有以下代码:

    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，此代码由于以下错误而导致编译失败:

[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

谁能看出这里出了什么问题吗？

第 37 行是:String package = comment.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();
