org.springframework.web.servlet.HandlerExceptionResolver，处理器异常解析器接口，将处理器( handler )执行时发生的异常，解析( 转换 )成对应的 ModelAndView 结果。代码如下：

package org.springframework.web.servlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.lang.Nullable;
public interface HandlerExceptionResolver {
 //解析异常，转换成对应的 ModelAndView 结果
 @Nullable
 ModelAndView resolveException(HttpServletRequest var1, HttpServletResponse var2, @Nullable Object var3, Exception var4);
}
