我将所有的

Spring配置转换为
@L_404_2@代码,但是我无法运行所有的测试(他们以前使用过的),因为我有一个丑陋的异常：

我尝试在我的测试类上放置@WebAppConfiguration,但这没有工作.
该项目是一个Spring MVC项目,但现在我正在测试服务层,那么为什么我需要把这个注释放在我的课上呢？
即使有这个注释,另一个错误即将到来.
那么这里有什么呢？@H_301_5@
解决方法
您的配置是正常的,除了一个地方
@ComponentScan(basePackages = { “org.example.springproject” })@H_301_5@
我会假设你的包中有其他@Configuration,这是由@ComponentScan(在您的异常中出现的DelegatingWebMvcConfiguration,最有可能由@EnableWebMvc在外部@Configuration中的某个地方导入)所选择的.@H_301_5@
@ComponentScan(basePackages = { “org.example.springproject” },excludeFilters = { @Filter(type = FilterType.ANNOTATION,value = Configuration.class) })@H_301_5@
