最近看代码，进入依赖的包的class文件，每个方法只有RuntimeException，如下(mock的):public class MyServiceContainer { public static final AppServiceContainer SHARED_CONTAINER; public MyServiceContainer() { throw new RuntimeException("com.loserwang.MyServiceContainer was loaded by " + MyServiceContainer.class.getClassLoader() + ", it should be loaded by Pandora Container. Can not load this fake sdk class. please refer to xxxxxx."); } public static AppServiceContainer createAppServiceContainer(ApplicationModel var0) { throw new RuntimeException("com.loserwang.MyServiceContainer was loaded by " + MyServiceContainer.class.getClassLoader() + ", it should be loaded by Pandora Container. Can not load this fake sdk class. please refer to xxxxxx."); } public static <T> T getInstance(Class<T> var0) { throw new RuntimeException("com.loserwang.MyServiceContainer was loaded by " + MyServiceContainer.class.getClassLoader() + ", it should be loaded by Pandora Container. Can not load this fake sdk class. please refer to xxxxxx."); } public static <T> List<T> getInstances(Class<T> var0, String... var1) { throw new RuntimeException("com.loserwang.MyServiceContainer was loaded by " + MyServiceContainer.class.getClassLoader() + ", it should be loaded by Pandora Container. Can not load this fake sdk class. please refer to xxxxxx.""); }然后下载source文件：public class MyServiceContainer { public static final AppServiceContainer SHARED_CONTAINER; public MyServiceContainer() { super(); } public static AppServiceContainer createAppServiceContainer(ApplicationModel var0) { // 具体逻辑代码 } public static <T> T getInstance(Class<T> var0) { // 具体逻辑代码 } public static <T> List<T> getInstances(Class<T> var0, String... var1) { // 具体逻辑代码 }既然class文件是通过java文件编译的，为什么会有如此大的区别呢？
