修改異常處理方法3中的全局異常處理Controller即可

package bjsxt.exception;

/**
 * Created by Administrator on 2019/2/14.
 * 全局異常處理類,使用SimpleMappingExceptionResolver 做全局異常處理
 * 優點：直接在一個方法裏對需要處理的異常跳轉不同的視圖，比較簡單方便
 * 缺點：無法把錯誤信息傳遞到視圖層
 
 
*/

@Configuration
public class GlobalException {

    /**
     *
     * @return
     */
    @Bean
    public SimpleMappingExceptionResolver getSimpleMappingExceptionResolver(){
        SimpleMappingExceptionResolver resolver=new SimpleMappingExceptionResolver();
        Properties properties=new Properties();
        
 
/**
         * 參數一：異常的類型，註意必須是異常類型的全名
         * 參數二：視圖名稱
         */
        properties.put("java.lang.ArithmeticException","error_arithmetic");
        properties.put("java.lang.NullPointerException","error_nullPointer");
        resolver.setExceptionMappings(properties);
        return resolver;
    }

}
