尽管这个项目已经为我工作了一段时间,但当我尝试在 Tomcat 中部署我的应用程序上下文时,我现在遇到了一个异常:
Servlet /testapp threw load() exception
java.lang.NoSuchMethodError: org.springframework.core.convert.converter.ConverterRegistry.addConverter(Ljava/lang/Class;Ljava/lang/Class;Lorg/springframework/core/convert/converter/Converter;)V
at org.springframework.core.convert.support.DefaultConversionService.addScalarConverters(DefaultConversionService.java:62)
根据我的阅读,如果应用程序中正在编译多个 Spring 版本,则可能会发生这种情况。但是,我已经完全清除了我的本地依赖库,以确认我的构建路径中只有我想要的版本。我的依赖项如下:
<properties>
<java-version>1.6</java-version>
<org.springframework.version>3.1.0.RELEASE</org.springframework.version>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
</properties>

我在 Eclipse 项目中没有编译器错误,它构建完美,没有警告或错误。但是,Tomcat 将我的单个测试 servlet 标记为不可用,当我跟踪日志时,上面的堆栈跟踪是我唯一的提示。
任何人都可以提供的任何帮助将不胜感激。我对 Spring 和 Spring MVC 的经验很少,所以我希望这只是一个完全让我无法理解的新手问题。
