java - 抽象方法错误

Question

我正在netbeans中开发一个项目，当我使用glassfish 3.1.2启动它时。一切正常。但是当我调用映射到以下方法的/invite url时

@RequestMapping(value = "/invite", method = RequestMethod.POST)
    @ExceptionHandler(GenericException.class)
    public ModelAndView create(@ModelAttribute(value = "preRegister") @Valid PreRegister preRegister, BindingResult result, HttpServletRequest request) {
        mav = new ModelAndView();
        validator.validate(preRegister, result);
        List<Role> roleList = null;
        if (result.hasErrors()) {
            mav.setViewName("user_populate_create");
            try {
                roleList = roleDao.list();
            } catch (Exception ex) {
                logger.error("UserController: Unable to list Roles: ", ex);
                throw new GenericException("UserController: Unable to list Roles: " + ex.getMessage());
            }
            if (roleList == null || roleList.isEmpty()) {
                throw new GenericException("UserController: Unable to list Roles");
            } else {
                mav.addObject("roles", roleList);
            }

        } else {
            String uuid = RandomUuid.generate();
            preRegister.setUrlCode(uuid);
            preRegister.setCreatedOn(Helper.rightNow());
            List<PreRegister> p;

            try {
                p = preRegisterDao.findbyQuery("checkAvailability", preRegister.getLoginId());
                if (p == null || p.isEmpty()) {
                    preRegisterDao.saveOrUpdate(preRegister);
                } else {
                    throw new GenericException("User Email Id is Exist! try With another Email Id ");
                }
            } catch (Exception exception) {
                exception.printStackTrace();
                logger.error("Invite user: ", exception);
                throw new GenericException("Exception :: " + exception.getMessage());

            }



        }
        return mav;

    }

甚至第一行方法也没有执行，并给了我这个堆栈跟踪

Answer 1

java.lang.AbstractMethodError当应用程序尝试调用抽象方法时抛出。通常，这个错误会被编译器捕获；如果自上次编译当前执行的方法以来某些类的定义发生了不兼容的更改，则此错误只会在运行时发生。

似乎这个问题是由于某些 jar 文件中的版本不兼容造成的。我无法从您的代码中计算出来。请检查这个线程。

Answer 2

发生此错误是因为在没有实际实现的情况下调用了抽象方法。它通常发生在某些库升级之后，而有些则没有。依赖项以某种方式丢失。

因此，请检查所有库升级是否成功完成。

这是一个关于 AbstractMethodError 如何发生的很好的示例和演示。

Answer 3

我因此处未提及的原因而出现此错误。

我正在使用 proguard，它混淆了一个类，然后导致 AbstractMethodError。只需要保持这个类在proguard。

Answer 4

这可能发生在 NetBeans 中，同时运行 Java 8 并使用 lambda 实现接口，然后更改接口签名。

简单的解决方案：运行Clean 并构建（默认情况下是Shift+ ）*F11

Answer 5

在异常（或发生异常的行）上放置一个断点以找出究竟是哪个类/方法导致了问题，然后在您的类路径中搜索该类的所有出现。如果您的类路径中有多个版本的类，请删除错误的版本。

Answer 6

在我的情况下，我也遇到了同样的问题，问题是我在两个不同的 jar 文件中有两个同名的 .class 文件。我从 pom.xml 中排除了它开始工作的 jar 文件！

Answer 7

我为此浪费了一些时间。

在 pom.xml 中，对于依赖项，如果您设置了 LATEST，可能是由于这个原因，请在此处指定正确的版本，这也是最佳实践

Answer 8

如果您将任何 spring 依赖项与 spring-boot 混合，也可能会发生这种情况。检查所有依赖项并查找是否存在 sping-boot 依赖项。如果您使用的是 spring-boot，则不要导入 spring 依赖项，因为 spring-boot 已经提供了一切。如果您尝试使用 spring，则不要使用 spring-boot，反之亦然。

Answer 9

我也遇到了这个错误，使用Tomcat 8.5. 另一条消息指出它需要Tomcat 9.0，但事实并非如此 - 我正在使用Spring Boot 2.2.5，我的问题是缺少两种方法：

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }

    @Override
    public void destroy() {
    }

添加这两种方法解决了这个问题。

Answer 10

Aspectj 版本 1.7.3 将解决此问题。请尝试一下
