我尝试调查给定包中可用的类。暂时我已经硬编码了类名，I get so many methods which are not available in the class when i try to print all the methods and parameter type the method takes

以下是我的主要课程，我在其中研究课程及其方法：

package com.hexgen.reflection;

`// removed imports to post question`
import com.hexgen.tools.HexgenClassUtils;

public class HexgenWebAPITest {

    @SuppressWarnings({ "rawtypes", "unchecked", "unused" })
    public static void main(String[] args) {
        HexgenWebAPITest test = new HexgenWebAPITest();
        HexgenClassUtils hexgenClassUtils = new HexgenClassUtils();
        String uri="";
        String[] mappingValues=null;
        HttpClientRequests httpRequest = new HttpClientRequests();
        Class parames = CreateRequisitionRO[].class;

        Class booleanVal;
        booleanVal = Boolean.TYPE;
        Class cls;


        try {
            List classNames = hexgenClassUtils.findMyTypes("com.hexgen.*");
            Iterator<Class> it = classNames.iterator();
            while(it.hasNext())
            {

                Class obj = it.next(); 
                System.out.println("Methods available in : "+obj.getName());
                System.out.println("===================================");
                if(obj.getName().equals("com.hexgen.api.facade.HexgenWebAPI")){
                    cls = Class.forName(obj.getName());
                    cls.getClass();
                    Method[] method = cls.getDeclaredMethods();
                    int i=1;
                    for (Method method2 : method) {
                        System.out.println(+i+":"+method2.getName());
                        Class[] parameterTypes = method2.getParameterTypes();
                        for (Class class1 : parameterTypes) {
                            System.out.println("Parameter Type : "+class1.getName());
                        }
                        i++;
                    }
                }

            }


        } catch (Exception ex) {
            ex.printStackTrace();
        }

    }

}

这是Utility Class 

package com.hexgen.tools;

// removed imports to post the question here

public class HexgenClassUtils {
    @SuppressWarnings({ "rawtypes"})
    public List<Class> findMyTypes(String basePackage) throws IOException, ClassNotFoundException
    {
        ResourcePatternResolver resourcePatternResolver = new PathMatchingResourcePatternResolver();
        MetadataReaderFactory metadataReaderFactory = new CachingMetadataReaderFactory(resourcePatternResolver);

        List<Class> candidates = new ArrayList<Class>();
        String packageSearchPath = ResourcePatternResolver.CLASSPATH_ALL_URL_PREFIX +
                                   resolveBasePackage(basePackage) + "/" + "**/*.class";
        Resource[] resources = resourcePatternResolver.getResources(packageSearchPath);
        for (Resource resource : resources) {
            if (resource.isReadable()) {
                MetadataReader metadataReader = metadataReaderFactory.getMetadataReader(resource);
                if (isCandidate(metadataReader)) {
                    candidates.add(Class.forName(metadataReader.getClassMetadata().getClassName()));
                }
            }
        }
        return candidates;
    }
    public String resolveBasePackage(String basePackage) {
        return ClassUtils.convertClassNameToResourcePath(SystemPropertyUtils.resolvePlaceholders(basePackage));
    }

    @SuppressWarnings({ "rawtypes", "unchecked" })
    public boolean isCandidate(MetadataReader metadataReader) throws ClassNotFoundException
    {
        try {
            Class c = Class.forName(metadataReader.getClassMetadata().getClassName());
            if (!c.isInterface() && c.getAnnotation(Controller.class) != null) {
                return true;
            }
        }
        catch(Throwable e){
        }
        return false;
    }

}

Spring 框架的不同部分在运行时执行检测，以扩充类并提供附加功能。Spring 使用三种不同的工具：

  • DynamicProxies - 这是 J2SE 的一个特性，它允许通过指定“方法处理程序”来“即时”生成接口 - 一种被调用以处理方法调用的方法。处理程序将查看方法签名和参数来决定要做什么。通常这将涉及在实现相同接口的具体目标类上调用相应方法之前或之后添加圆顶功能。（因此名称为“代理”）。当类由接口支持时，动态代理是默认设置。

  • 字节码工程（BCEL）。这涉及覆盖在第一次需要时加载类的类加载器方法。被覆盖的方法返回一个在运行时生成的子类，并包含额外的功能。Spring 使用的库是 'cglib'，它建立在 'asm' 之上。. . 这些库优先考虑性能而不是易用性。. . （易用性不是问题，因为 Spring 用户不为自己做任何字节码工程——只使用检测类）。

  • AspectJ 编织。这涉及使用编译时编织或运行时编织。在后者的情况下，使用特殊的 Java 代理（JVM 的命令行参数）而不是拦截类加载器。

检测的示例是基于注释的事务、安全注释、验证等。

您正在观察第二种类型的检测（运行时生成的子类），这是具体类的默认值。. . （AspectJ 可以用于更复杂的情况，例如在 Spring 容器之外的类上提供依赖注入）。
