【中文标题】java.lang.ClassFormatError:类文件 javax/faces/webapp/FacesServlet 中非本机或抽象方法中的缺失代码属性【英文标题】:java.lang.ClassFormatError: Absent Code attribute in method that is not native or abstract in class file javax/faces/webapp/FacesServlet 【发布时间】:2011-12-10 02:08:28 【问题描述】:我想将 Mojarra 2.1 与 Tomcat 7 一起使用, 所以我在我的 pom 文件中添加了以下依赖项:
<dependency>
<groupId>com.sun.faces</groupId>
<artifactId>jsf-api</artifactId>
<version>2.1.2</version>
</dependency>
<dependency>
<groupId>com.sun.faces</groupId>
<artifactId>jsf-impl</artifactId>
<version>2.1.2</version>
</dependency>
但是,当我尝试启动 Tomcat 时,出现以下异常:

这是怎么引起的,我该如何解决?
这是我的web.xml

【问题讨论】:
你可能想跟踪这个话题:***.com/questions/7806986/…今天其他人也遇到了同样的Maven和类路径污染问题。 java.lang.ClassFormatError: Absent Code attribute in method that is not native or abstract in class file javax/faces/webapp/FacesServlet的可能重复 【参考方案1】:我有同样的问题,它以某种方式接缝
<groupId>javax</groupId>
<artifactId>javaee-web-api</artifactId>
或
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
在将它们设置为范围提供后(或在 Maven 测试中启动服务器时完全删除它们)它开始为我工作。
@查看此博客:java.lang.ClassFormatError : Absent Code attribute in method that is not native or abstract in class file … - 它讨论了javax.persistence.GenerationType
的问题,但我认为你和我遇到了同样的问题。
【讨论】:
【参考方案2】:这个解决方法为我修复了它: https://rogerkeays.com/java-lang-classformaterror-exception-with-eclipselink-static-weaving-solved
【讨论】:
【参考方案3】:变化:
<dependency>
<groupId>com.sun.faces</groupId>
<artifactId>jsf-impl</artifactId>
<version>2.1.2</version>
</dependency>
收件人:
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>javax.faces</artifactId>
<version>2.1.6</version>
</dependency>
【讨论】:
【参考方案4】:我和你有同样的问题,发现从servlet-api
更改为javax.servlet.api
可以解决问题。希望这有帮助。请注意,我使用的是 Juno Eclipse、Tomcat 7、Dynamic Web Module 3.0 和 JDK 1.7。
