类加载时机启动main方法时创建类的实例创建子类的实例访问类的静态方法ReflectionClass.forName()-XX:+TraceClassLoading在vm选项中添加这条命令，log会加载类时打印加载代码示例这里只写了部分加载方法，请尝试@RequestMapping(value="/test1",method={RequestMethod.GET,RequestMethod.POST},produces="application/json;charset=utf-8")publicStringtest1(){try{Classc=Class.forName("com.example.demo.my.view.postConstruct.MyClass");}catch(ClassNotFoundExceptione){e.printStackTrace();}return"test1";}@RequestMapping(value="/test2",method={RequestMethod.GET,RequestMethod.POST},produces="application/json;charset=utf-8")publicStringtest2(){Classc=MyClass.class;return"test2";}@RequestMapping(value="/test3",method={RequestMethod.GET,RequestMethod.POST},produces="application/json;charset=utf-8")publicStringtest3(){MyClassc=新的我的类（）；返回“测试3";}打印结果
