Java Spring给出非法状态异常：加载ApplicationContext失败，提示如何解决？

NetBeans向我显示以下错误消息：

未能加载ApplicationContext org.springframework.test.context.cache.DefaultCacheAwareContextLoaderDelegate.loadContext（DefaultCacheAwareContextLoaderDelegate.java:125）org.springframework.test.context.support.DefaultTestContext.getApplicationContext（DefaultTestContext.java:107）org.springframework.test.context.web.ServletTestExecutionListener.setupRequestContextIfEssential（ServletTestExecutionListener.java:190）org.springframework.test.context.web.ServletTestExecutionListener.prepareTestInstance（ServletTestExecutionListener.java:132）org.springframework.testContext.TestContextManager.prepareTestInstance（TestContextManager.java:242）org.springframework.test.context.junit4.SpringJUnit4ClassRunner.createTest（SpringJUnit4ClassRunner.java:227）org.springframework.test.context.junit4.SpringJUnit4ClassRunner$1.runReflectiveCall（SpringJUnit4ClassRunner.java:289）org.junit.internal.runners.model.ReflectiveCallable.run（ReflectiveCallable.java:12）org.springframework.test.context.junit4.SpringJUnit4ClassRunner.methodBlock（SpringJUnit4ClassRunner.java:291）org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild（SpringJUnit4ClassRunner.java:246）org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild（SpringJUnit4ClassRunner.java:97）org.junit.runners.ParentRunner$3.run（ParentRunner.java:238）org.junit.runners.ParentRunner$1.schedule（ParentRunner.java:63）org.junit.runners.ParentRunner.runners儿童（ParentRunner.java:236）org.junit.runners.ParentRunner.access$000（ParentRunner.java:53）org.junit.runners.ParentRunner$2.evaluate（ParentRunner.java:229）org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate（RunBeforeTestClassCallbacks.java:61）org.springframework.test.context.junit4.statements.runnextestclasscallbacks.evaluate（runnextestclasscallbacks.java:70）org.junit.runners.ParentRunner.ParentRunner.java:309）org.springframework.test.context.junit4.SpringJUnit4ClassRunner.run（SpringJUnit4ClassRunner.java:190）fi.helskini.cs.tmc.testrunner.testrunner$TestingRunnable.runTestCase（testrunner.java:134）fi.helskinki.cs.tmc.testrunner.testrunner$TestingRunnable.doRun（testrunner.java:89）fi.helskingi.cs.tmc.testrunner$TestingRunnable.runner.runnable.run（TestRunner.java:70）java.lang.Thread.run（Thread.java:748）

这是我的代码：

Hellomodel应用程序：

package wad.hellomodel;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class HelloModelApplication {

public static void main(String[] args) throws Exception {
    SpringApplication.run(HelloModelApplication.class, args);
}
}

Hellomodel控制器：

    import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;

@Controller
public class HelloModelController {

 @GetMapping("/")
public String title(Model model, @RequestParam String title) {
    model.addAttribute("title", title);
    return "index";
}

@GetMapping("/")
public String person(Model model, @RequestParam String person) {
    model.addAttribute("person", person);
    return "index";


   }

}

Localhost也不会显示。我对Spring真的很陌生，我想知道为什么这不起作用

堆栈跟踪中的第一行讨论了测试上下文，但您向我们展示了生产代码。您有任何测试吗？您的pom如何？我添加了pom和测试。整个包由大学提供，所以我不太确定这是他们的问题还是我的问题？堆栈跟踪看起来不完整（没有“原因：”）格式与通常不同（无“at”）。也许Netbeans只是向您展示了一个摘要？一个完整的stacktrace应该被写入控制台。堆栈跟踪中的第一行讨论了测试上下文，但您向我们展示了生产代码。您有任何测试吗？您的pom呢？我添加了pom和测试。整个包是由大学提供的，所以我不太确定是否有是他们的问题还是我的问题？stacktrace看起来不完整（否“由：”）并且与通常的格式不同（否“在”）。可能Netbeans只是向您显示一个摘要？应该将完整的stacktrace写入控制台。
