Java 创建 JUnit 测试时没有此类方法错误

No Such Method Error when creating JUnit test

提问by IaCoder

I've tried figuring out this problem for the last 2 days with no luck. I'm simply trying to create an annotation based JUnit test using the spring framework along with hibernate.

在过去的 2 天里，我一直在尝试解决这个问题，但没有成功。我只是尝试使用 spring 框架和 hibernate 创建一个基于注释的 JUnit 测试。

My IDE is netbeans 6.5 and I'm using hibernate 3, spring 2.5.5 and JUnit 4.4.

我的 IDE 是 netbeans 6.5，我使用的是 hibernate 3、spring 2.5.5 和 JUnit 4.4。

Here's the error I'm getting:

这是我得到的错误：

The java.lang.NoSuchMethodErroralways indicates that the version of a class that was on your compiler's classpath is different from the version of the class that is on your runtime classpath (had the method been missing at compile-time, the compile would have failed.)

将java.lang.NoSuchMethodError始终表明，一类是在你的编译器的类路径的版本是从上运行时类路径类的版本不同（有方法在编译时失踪，编译就失败了。）

In this case, you had a different version of org.objectweb.asm.ClassWriteron your classpath at compile time than is on your runtime classpath.

在这种情况下，您org.objectweb.asm.ClassWriter在编译时在类路径上的版本与在运行时类路径上的版本不同。

回答by krosenvold

I think you are picking up an incorrect version of asm.jar somewhere in the classpath you are using for your tests.

我认为您在用于测试的类路径中的某处选择了不正确的 asm.jar 版本。

回答by Xian

Definitely you have different versions of your ClassWriter class at runtime than compile time.

当然，您在运行时拥有与编译时不同版本的 ClassWriter 类。

I had a similar error using Spring 2.5 with Hibernate on NetBeans 6.5. One way I resolved the issue was downloading Spring 3.0 M2 and creating a NetBeans library I called Spring_3 using the jars from the distro. This library also had to include the antlr-runtime-3.0.jar.

我在 NetBeans 6.5 上使用 Spring 2.5 和 Hibernate 时遇到了类似的错误。我解决该问题的一种方法是下载 Spring 3.0 M2 并使用发行版中的 jar 创建一个名为 Spring_3 的 NetBeans 库。该库还必须包含 antlr-runtime-3.0.jar。

I would like to share my suggestion for anyone who comes across this JUnit Testing for Android; none of the above worked for me and this was a simple fix:

我想向遇到此 Android JUnit 测试的任何人分享我的建议；以上都不适合我，这是一个简单的修复：

In Eclipse>>project properties>>Android>>make sure that the project you are testing is referenced under Library. 'is library' can remain unchecked

在Eclipse>>project properties>>Android>>请确保您正在测试的项目库下引用。“是图书馆”可以保持未选中状态
