SpringMVC框架中的异常解析器-ExceptionHandler和HandlerExceptionResolver(转)

@Controller
public class AccessController {
/**
* 处理这个Controller内部发生的运行时异常
*/
@ ExceptionHandler (RuntimeException.class)
public String runtimeExceptionHandler(RuntimeException runtimeException,ModelMap modelMap) {
logger.error(runtimeException.getLocalizedMessage());

modelMap.put("status", IntegralConstant.FAIL_STATUS);
return "exception";
}
}
处理全局异常

import java.util.HashMap;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.log4j.Logger;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.HandlerExceptionResolver;
import org.springframework.web.servlet.ModelAndView;

/**
* 全局异常处理器，跳转到错误页面。
*
* @author leiwen@FansUnion.cn
*/
@Component
public class SystemExceptionHandler implements HandlerExceptionResolver {

public static final String ERROR_500 = "/views/error/500.jsp";

private Logger logger = Logger.getLogger(getClass());

public ModelAndView resolveException(HttpServletRequest request,
HttpServletResponse response, Object handler, Exception ex) {
logger.error("Catch-exception");
ex.printStackTrace();

//other code
// 根据实际页面来修改
return new ModelAndView(ERROR_500);
}
