springMvc--全局异常处理

本文中只测试了, 异常处理接口HandlerExceptionResolver

步骤

1.自定义异常类：

/**
 * 自定义全局异常处理类
 */
public class CustomerExceptionResolver implements HandlerExceptionResolver {

    @Override
    public ModelAndView resolveException(HttpServletRequest request,
            HttpServletResponse response, Object handler, Exception ex) {
        
        return new ModelAndView("500", "message", ex.getMessage());
    }

}

2.springMvc配置文件中增加

<!-- 注册全局异常处理类 -->
    <bean class="zpark.exception.CustomerExceptionResolver"/>

3.controller

@RequestMapping("/test")
    public String test(){
        throw new RuntimeException("出错了,请修复..");
    }

4.异常页面捕获异常信息

  系统异常:${message }
