Spring JUnit Test Error
提问by Robert Brooks
I am receiving the following error when I attempt to run my Spring JUnit test. I am just trying to get familiar with creating JUnits using the Spring Framework.
当我尝试运行 Spring JUnit 测试时收到以下错误。我只是想熟悉使用 Spring 框架创建 JUnit。

I had this exact same issue when upgrading from Spring 3.0.6 and to 3.1.0 release. Here is the solution:
从 Spring 3.0.6 升级到 3.1.0 版本时，我遇到了完全相同的问题。这是解决方案：
Some of your dependencies are listed as being the 3.1.0 version, but they resolve their transitive dependencies to the older versions which don't have the method listed in the error message.
您的某些依赖项被列为 3.1.0 版本，但它们解决了对旧版本的传递依赖项，这些旧版本没有错误消息中列出的方法。
If you use Eclipse, open the pom.xml and look at the dependency hierarchy tab. Some libraries you declared will be listed as version 3.1.0 but have a resolved dependency of 3.0.6. For me, I had spring-security-config and spring-security-taglibs listed as version 3.1 in my pom, but they resolved dependencies such as spring-core and spring-expression as 3.0.6.
如果您使用 Eclipse，请打开 pom.xml 并查看依赖项层次结构选项卡。您声明的某些库将列为 3.1.0 版，但已解析依赖项 3.0.6。对我来说，我的 pom 中将 spring-security-config 和 spring-security-taglibs 列为 3.1 版，但它们将 spring-core 和 spring-expression 等依赖项解析为 3.0.6。
To resolve this, explicitly list each of the highest transitive dependencies explicitly in your pom. For example, I was originally counting on spring-security-config to bring in spring-core as a transitive dependency, so I did not list the spring-core artifact in my pom. But to fix this issue I changed my pom to explicitly include spring-core (version 3.1.0). I added direct dependencies for every resolved dependency in my pom that was being resolved to an older version, and then it worked!
要解决此问题，请在您的 pom 中明确列出每个最高的传递依赖项。例如，我最初指望 spring-security-config 引入 spring-core 作为传递依赖，所以我没有在我的 pom.xml 中列出 spring-core 工件。但是为了解决这个问题，我改变了我的 pom 以明确包含 spring-core（版本 3.1.0）。我为正在解析为旧版本的 pom 中的每个已解析的依赖项添加了直接依赖项，然后它就起作用了！
Hope this helps...

If solutions above are not working, it might be eclipse's fault: in eclipse, on the project -> properties -> java build path -> Librairies -> if there is "Junit 4", remove it.
如果上述解决方案不起作用，则可能是 eclipse 的错误：在 eclipse 中，在项目上 -> 属性 -> java 构建路径 -> 库 -> 如果有“Junit 4”，请将其删除。
I had this stacktrace:
我有这个堆栈跟踪：
java.lang.NoSuchMethodError: org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runLeaf(Lorg/junit/runners/model/Statement;Lorg/junit/runner/Description;Lorg/junit/runner/notification/RunNotifier;)V

at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:89)
And of course updating the pom wasn't the solution...
当然，更新 pom 不是解决方案......

In my case,I had dependency one junit-dep and one junit, when I remove the junit-dep, everything is ok.
就我而言，我依赖一个 junit-dep 和一个 junit，当我删除 junit-dep 时，一切正常。

It complains about java.lang.NoSuchMethodErrorand I think this has to do with your spring dependencies. Try changing your spring dependencies like this:
它抱怨java.lang.NoSuchMethodError，我认为这与您的 spring 依赖项有关。尝试像这样更改您的 spring 依赖项：
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>

</dependency>
<dependency>
<groupId>org.springframework</groupId>

</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>3.1.0.RC1</version>
</dependency>
And I don't know where following dependencies come from, but I think they might need correction with their artifactId as well:
而且我不知道以下依赖项来自哪里，但我认为他们可能也需要更正其 artifactId：
<dependency>
<groupId>org.springframework</groupId>

</dependency>
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongodb-java-driver</artifactId>
<version>2.7.2</version>
</dependency>
And one final thing that I want you to consider, do you really, really need ALL of those dependencies?
我希望您考虑的最后一件事是，您真的、真的需要所有这些依赖项吗？

Jay is correct. Based on what he said and the error originating from org.springframework.beans, review your dependency graph for said project and resolve any version conflicts by excluding transitive dependencies on org.springframework.beansand explicitly stating a dependency on the latest or the correct version of org.springframework.beans.
杰是对的。根据他所说的以及源自org.springframework.beans的错误，检查您的项目的依赖关系图并通过排除对org.springframework.beans 的传递依赖并明确说明对最新或正确版本的依赖来解决任何版本冲突的org.springframework.beans。
The same should probably be done to other dependencies, but if it ain't broke don't fix it ;) unless you can't get passed your OCD, like myself.
对其他依赖项可能也应该这样做，但如果它没有损坏，请不要修复它；) 除非您无法通过强迫症，就像我自己一样。
I leveraged Netbeans by selecting the project, right click-> show dependency. Once in the dependency graph view, search for Beans. Double click on the dependency and right click to resolve version conflict where a wizard like window will provide additional configurations to resolve the conflict. Piece of cake!
我通过选择项目，右键单击-> 显示依赖来利用 Netbeans。在依赖关系图视图中，搜索 Beans。双击依赖项并右键单击以解决版本冲突，其中类似窗口的向导将提供其他配置来解决冲突。小菜一碟！
Thanks Jay!
谢谢杰！

add this one to your pom File, I had the same ERROR, but I have done this, now it works for me,
将此添加到您的 pom 文件中，我有同样的错误，但我已经这样做了，现在它对我有用，
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>3.1.0.RC1</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>3.0.0.RELEASE</version>
</dependency>
Note: I have POM parent, and POM child, and I wanted to test my child project, but I got error. mvn test.... so I have done this thing. in Parent.
注意：我有 POM 父项和 POM 子项，我想测试我的子项目，但出现错误。mvn test....所以我做了这件事。在家长。
with version and in child without. like this one org.springframework spring-beans
与版本和在孩子没有。像这样一个 org.springframework spring-beans
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
</dependency>
try it.
尝试一下。
