@ControllerAdvice全局异常处理器无法捕获异常,问题解决

springmvc.xml配置文件中扫描的包是package=“com.test.controller”,而testException在com.test.exception包下,无法扫描到这个类,所以该全局异常处理类未生效

---

解决方案:
将该类移到controller包下,即可扫描到,也就是说交给了ioc容器,开始生效

---

1.Controller层的代码

//web层
@RestController
@RequestMapping("/checkitem")
public class CheckItemController {
	@Reference //远程注入 com.alibaba.dubbo.config.annotation.Reference;
	private CheckItemService checkItemService;
	@RequestMapping("/test")
	public Result test(@RequestBody QueryPageBean queryPageBean) {
		PageResult pageResult = checkItemService.findPage(queryPageBean);
		int i = 1 / 0;//模拟异常
		return new Result(true, MessageConstant.QUERY_CHECKITEM_SUCCESS);
	}
}

2.全局异常处理器

/**
 * 全局异常处理器,
 */
@ControllerAdvice
public class testException {
	@ExceptionHandler(Exception.class)
	@ResponseBody
	public Result myException() {
		return new Result(false, "全局异常处理器", "this is a data");
	}
}

3.浏览器返回的结果
