Java8是往并行方向走的.由面向对象到函数式编程. 在支持函数式编程的同时还可以支持面向对象的开发. 在JDK1.8里面,接口里面可以有实现方法的!默认方法,default.实现这个接口. 接口里面可以有静态方法 注意Lambda表达式的类型势函数.但是在Java中,Lambda表达式是对象!他们必须依赖于一类特别的对象类型-函数式接口 关于Function<T,R>接口 public class FunctionTest { public static void main(String[]
@ControllerAdvice 对Controller进行"切面"环绕 结合方法型注解 @ExceptionHandler 用于捕获Controller中抛出的指定类型的异常,从而达到不同类型的异常区别处理的目的. @ControllerAdvice(basePackages = "mvc") public class ControllerAdvice { @ExceptionHandler(RuntimeException.class) public Mode
