//全局捕获异常对basePackages的包生效
@ControllerAdvice(basePackages = "com.wld.controller")
public class GlobalExpectionHandler(){

	@ExceptionHandler(RuntimeException.class)
	//@ResponseBody 返回json格式

	@ResponseBody
	public Map<String,Object> errorResult(){
		Map<String,Object> resultMap = new HashMap<String,Object>();
		resultMap.put("errorCode", "500");
		resultMap.put("errorMessage", "system Error")
