目前，我正在尝试为我工作旁边正在进行的学校项目设置 Spring MVC Controller 测试。通常我在 php 和 Laravel 这样的框架中编程，所以这对我来说很新。问题是我不知道如何解决加载 ApplicationContext 时不断弹出的问题。感谢您的帮助。
更新:
我现在被告知测试用例不在我的应用程序服务器中使用 jndi 引用。所以这个引用在测试用例上会失败，它在启动应用程序时运行良好。现在，我制作了第二个名为 servlet-test.xml(在下面列出) 的文件，它使用对端口 3306 上的数据库的引用。我只在测试时使用这个文件，而不是在启动应用程序时使用。但是当我使用这种方法时，我得到了 Following error: Error creating bean with name 'productController': Injection of autowired dependencies failed。欢迎任何帮助，因为我正在努力为我的学校项目设置 MVC Controller 测试。与我一起工作的其他学生也遇到了与我相同的问题，所以我也可以帮助他们。
我怀疑是以下问题，但我不确定如何解决。

最佳答案
根据您的堆栈跟踪，当应用程序上下文正在初始化时，它仍然会尝试加载错误的配置文件 (servlet.xml)，但应该加载 servlet-test.xml。请尝试使用根 (src) 文件夹中的路径更改您的配置位置，例如:
@ContextConfiguration({"file:src/main/web/WEB-INF/servlet-test.xml", "file:src/main/web/WEB-INF/dispatcher-servlet.xml"})
P.S 您也可以尝试将测试配置 (servlet-test.xml) 移动到 src/test/resources 并从类路径加载它:“classpath:servlet-test.xml”。您也可以在 stackoverflow 上查看此线程:Spring @ContextConfiguration how to put the right location for the xml用于对类似问题的扩展讨论。
关于java - Spring MVC 测试设置在加载 ApplicationContext.xml 时失败，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/39850364/
我有一个Ruby程序，它使用rubyzip压缩XML文件的目录树。gem。我的问题是文件开始变得很重，我想提高压缩级别，因为压缩时间不是问题。我在rubyzipdocumentation中找不到一种为创建的ZIP文件指定压缩级别的方法。有人知道如何更改此设置吗？是否有另一个允许指定压缩级别的Ruby库？ 最佳答案 这是我通过查看rubyzip内部创建的代码。level=Zlib::BEST_COMPRESSIONZip::ZipOutputStream.open(zip_file)do|zip|Dir.glob("**/*")d
很好奇，就使用rubyonrails自动化单元测试而言，你们正在做什么？您是否创建了一个脚本来在cron中运行rake作业并将结果邮寄给您？git中的预提交Hook？只是手动调用？我完全理解测试，但想知道在错误发生之前捕获错误的最佳实践是什么。让我们理所当然地认为测试本身是完美无缺的，并且可以正常工作。下一步是什么以确保他们在正确的时间将可能有害的结果传达给您？ 最佳答案 不确定您到底想听什么，但是有几个级别的自动代码库控制:在处理某项功能时，您可以使用类似autotest的内容获得关于哪些有效，哪些无效的即时反馈。要确保您的提

我有一个对象has_many应呈现为xml的子对象。这不是问题。我的问题是我创建了一个Hash包含此数据，就像解析器需要它一样。但是rails自动将整个文件包含在.........我需要摆脱type="array"和我该如何处理？我没有在文档中找到任何内容。 最佳答案 我遇到了同样的问题；这是我的XML:我在用这个:entries.to_xml将散列数据转换为XML，但这会将条目的数据包装到中所以我修改了:entries.to_xml(root:"Contacts")但这仍然将转换后的XML包装在“联系人”中，将我的XML代码修改为
我正在编写一个包含C扩展的gem。通常当我写一个gem时，我会遵循TDD的过程，我会写一个失败的规范，然后处理代码直到它通过，等等......在“ext/mygem/mygem.c”中我的C扩展和在gemspec的“扩展”中配置的有效extconf.rb，如何运行我的规范并仍然加载我的C扩展？当我更改C代码时，我需要采取哪些步骤来重新编译代码？这可能是个愚蠢的问题，但是从我的gem的开发源代码树中输入“bundleinstall”不会构建任何native扩展。当我手动运行rubyext/mygem/extconf.rb时，我确实得到了一个Makefile(在整个项目的根目录中)，然后当
我有一个围绕一些对象的包装类，我想将这些对象用作散列中的键。包装对象和解包装对象应映射到相同的键。一个简单的例子是这样的:classAattr_reader:xdefinitialize(inner)@inner=innerenddefx;@inner.x;enddef==(other)@inner.x==other.xendenda=A.new(o)#oisjustanyobjectthatallowso.xb=A.new(o)h={a=>5}ph[a]#5ph[b]#nil,shouldbe5ph[o]#nil,shouldbe5我试过==、===、eq?并散列所有无济于事。
鉴于我有以下迁移:Sequel.migrationdoupdoalter_table:usersdoadd_column:is_admin,:default=>falseend#SequelrunsaDESCRIBEtablestatement,whenthemodelisloaded.#Atthispoint,itdoesnotknowthatusershaveais_adminflag.#Soitfails.@user=User.find(:email=>"admin@fancy-startup.example")@user.is_admin=true@user.save!ende
我正在查看instance_variable_set的文档并看到给出的示例代码是这样做的:obj.instance_variable_set(:@instnc_var,"valuefortheinstancevariable")然后允许您在类的任何实例方法中以@instnc_var的形式访问该变量。我想知道为什么在@instnc_var之前需要一个冒号:。冒号有什么作用？ 最佳答案 我的第一直觉是告诉你不要使用instance_variable_set除非你真的知道你用它做什么。它本质上是一种元编程工具或绕过实例变量可见性的黑客攻击
我有一些Ruby代码，如下所示:Something.createdo|x|x.foo=barend我想编写一个测试，它使用double代替block参数x，这样我就可以调用:x_double.should_receive(:foo).with("whatever").这可能吗？ 最佳答案 specify'something'dox=doublex.should_receive(:foo=).with("whatever")Something.should_receive(:create).and_yield(x)#callthere
Sinatra新手；我正在运行一些rspec测试，但在日志中收到了一堆不需要的噪音。如何消除日志中过多的噪音？我仔细检查了环境是否设置为:test，这意味着记录器级别应设置为WARN而不是DEBUG。spec_helper:require"./app"require"sinatra"require"rspec"require"rack/test"require"database_cleaner"require"factory_girl"set:environment,:testFactoryGirl.definition_file_paths=%w{./factories./test/
