我希望你能帮助我.. 我有一个 spring-boot 应用程序，它在一个文件夹中加载一些 jar（带有带注释的类和方法@Test）@TestFactory，并在 JSON 中加载所有 jar 名称 - 类名称 - 方法Test名称。当我调用 get 服务时/getTestList，我会像这样查看这个 json，例如：

{jarFile:{classFileName:{methodTestName1:"xxxx",methodTestName2:"yyy"},{classFileName2:{methodTestName1:"xxxx",methodTestName2:"yyy"} }

这是Controller.class：

 @RestController
public class Controller {
public JarClassMethod getAllTests() throws IllegalArgumentException,  NoSuchMethodException, 
InvocationTargetException, IllegalAccessException, IOException,LinkageError, ClassNotFoundException {

    JarClassMethod testClassObjMap= new JarClassMethod();
    LoadLibrary loadLibrary=new LoadLibrary();
    List<JarFile> jarList= loadLibrary.getListJar().stream().map(f -> {
        try {
            return new JarFile(f);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    })
        .collect(Collectors.toList());

    for (JarFile j : jarList) {
        for (Enumeration<JarEntry> entries = j.entries(); entries.hasMoreElements(); ) {
            JarEntry entry = entries.nextElement();
            String file = entry.getName();
            if (file.endsWith(".class")) {
                String classname = file.replaceAll("/", ".")
                        .substring(0, file.lastIndexOf("."));
                try {
                    Class<?> currentClass = Class.forName(classname);
                    List<String> testMethods = new ArrayList<>();
                    for (int i = 0; i < currentClass.getMethods().length; i++) {
                        Method method = currentClass.getMethods()[i];
                        Annotation annTest = method.getAnnotation(Test.class);
                        Annotation annTestFactory = method.getAnnotation(TestFactory.class);
                        if (annTest != null || annTestFactory != null) {
                            testMethods.add(method.getName());
                        }
                    }//fine for metodi
                    if (testMethods.size() >=1) {
                        testClassObjMap.put(j.getName().substring(j.getName().lastIndexOf("\\")+1),classname,testMethods);
                        System.out.format("%s %s %s",j.toString(),classname,testMethods);
                    }
                }catch (NoClassDefFoundError e) {
                    System.out.println("WARNING: failed NoClassDefFoundError " + classname + " from " + file);
                } 
                catch (Throwable e) {
                    System.out.println("WARNING: failed to instantiate " + classname + " from " + file);
                }

            }//if .class
        }//chiudo jarentry for
    }//chiudo jarfile for
    return testClassObjMap;
}

@ResponseStatus(value = HttpStatus.OK)
@RequestMapping(value = "/getTestList", method = RequestMethod.GET)
public ResponseEntity<JarClassMethod> getTestList() throws IOException, ClassNotFoundException, NoSuchMethodException, IllegalAccessException, InvocationTargetException {
    JarClassMethod testClassObjMap=this.getAllTests();
    return new ResponseEntity<>(testClassObjMap, HttpStatus.OK);
}

使用方法getAllTests()我首先像外部库一样加载 jar，然后使用一个用于迭代所有 jarsFile，另一个用于迭代所有类，最后使用另一个用于使用注释@Test或@TestFactory.

在我的 Windows 电脑上它可以正常工作，但是当我打包项目并将这个 jar 放在 Linux 服务器上时，我遇到了这个错误：

        There was an unexpected error (type=Internal Server Error, status=500).
    loader constraint violation: when resolving method
 "com.fasterxml.jackson.databind.ser.impl.ReadOnlyClassToSerializerMap.untypedValueSerializer(Ljava/lang/Class;)Lcom/fasterxml/jackson/databind/JsonSerializer;" the class loader (instance of 
org/springframework/boot/loader/LaunchedURLClassLoader) of the current class, 
com/fasterxml/jackson/databind/SerializerProvider, and the class loader (instance of 
sun/misc/Launcher$AppClassLoader) for the method's defining class, 
com/fasterxml/jackson/databind/ser/impl/ReadOnlyClassToSerializerMap, have different Class objects for 
the type com/fasterxml/jackson/databind/JsonSerializer used in the signature

我试图从 spring-boot 依赖项中排除 Jackson，但 Response ofgetTestList()不起作用。其他 Jars 文件也使用了 Jackson 库。

这是我的 pom.xml：pomxml

请帮助我.. 我累了 3 天。:-P 谢谢和

问候朋友..
