1. 自定義異常類

package cn.test.exception;

public class SysException extends Exception{

    //異常提示信息
    private String message;


    public SysException(String message) {
        this.message = message;
    }

    @Override
    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }


}

2. 自定義異常處理器 implements HandlerExceptionResolver

package cn.test.exception;

import org.springframework.web.servlet.HandlerExceptionResolver;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class SysExceptionResolver implements HandlerExceptionResolver {
    @Override
    public ModelAndView resolveException(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) {

        e.printStackTrace();

        SysException sysException = null;
        if(e instanceof SysException ){
            sysException = (SysException)e;
        }else{
            sysException = new SysException(e.getMessage());
        }

        ModelAndView modelAndView = new ModelAndView();
        modelAndView.addObject("message",sysException.getMessage());

        modelAndView.setViewName("error");

        return modelAndView;
    }
}

４. 配置異常處理器

<!--配置異常處理器-->
<bean id="sysExceptionResolver" class="cn.test.exception.SysExceptionResolver"/>
