java.lang.AbstractMethodError：javax.servlet.jsp.JspFactory.getJspApplicationContext（Ljavax / servlet / ServletContext;）Ljavax / servlet / jsp / JspApplicationContext;

您好， 我正在开发vaadin中的Web服务器。我的应用程序工作正常，但现在当我启动它时，我有以下错误

服务器是Tomcat 7.0.59版。 java版本是1.7。 我发现错误可能是以下罐子：

servlet.jar
servlet-api.jar
j2ee.jar

因为他们有文件javax.servlet，但我没有它们。 https://community.oracle.com/thread/1397338?start=0

感谢您的帮助

您缺少项目的以下依赖性：

<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
    <version>7.0.59</version>
</dependency>

在包含org.apache.jasper.compiler.Validator的库期望它作为javax.servlet.jsp.JspFactory实现的类定义之间可能存在版本控制问题。

为类提供3个具有相同二进制名称的jar并不是一个好习惯。除非你知道类加载器会选择哪个类，否则你将对行为的内容不知所措。 减少罐子的数量，只包括你需要的罐子。

如果那时仍然存在此冲突，请检查包含org.apache.jasper.compiler.Validator的库的依赖关系树，并确保您提供的javax.servlet.jsp.JspFactory实现实现了您在依赖树。

会发生什么事情：

-- my-framework-1.0.0 --
interface A {
  method b ();
}

class AFactory {
  A getDefault () { ... }

-- my-framework-2.0.0 --
interface A {
  method b(String s);
}

class AFactory {
  A getDefault () { ... }

-- my-implementation --
class B {
  public void act () {
    AFactory.getDefault().b();
  }
}

只要使用my-framework-1.0.0进行部署，这将正常工作。使用my-frameworke-2.0.0进行部署将使其中断。

如果您的类加载器选择my-framework-1.0.0进行编译，但您的打包程序选择my-frameworke-2.0.0，则可能无法在IDE中看到此问题。
