java接口开发 全局异常,全局异常处理
習(xí)慣在controller中進(jìn)行try catch 異常處理了，但其實(shí)如果不做異常處理的話，也可以采取全局異常處理的方式進(jìn)行解決，同樣方便統(tǒng)一使用、維護(hù)，具體實(shí)現(xiàn)如下：
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.validation.ConstraintViolationException;
import org.apache.shiro.authz.UnauthorizedException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.validation.BindException;
import org.springframework.web.HttpRequestMethodNotSupportedException;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.view.json.MappingJackson2JsonView;
@ControllerAdvice
public class GlobalExceptionHandler {
/**
*
* @desc 移動(dòng)端接口請(qǐng)求參數(shù)驗(yàn)證異常類
* @param e
* @param request
* @param response
* @return
*/
@ExceptionHandler(ConstraintViolationException.class)
public ModelAndView constraintViolationException(ConstraintViolationException e, HttpServletRequest request, HttpServletResponse response) {
ModelAndView modelAndView = new ModelAndView(new MappingJackson2JsonView());
modelAndView.addObject("code", MobileCode.HTTP_REQUEST_PARAMETER_CODE);
modelAndView.addObject("msg", "傳入?yún)?shù)格式不正確：" + e.getMessage());
return modelAndView;
}
@ExceptionHandler(BindException.class)
public ModelAndView bindException(BindException e, HttpServletRequest request, HttpServletResponse response) {
ModelAndView modelAndView = new ModelAndView(new MappingJackson2JsonView());
modelAndView.addObject("code", MobileCode.HTTP_REQUEST_PARAMETER_CODE);
modelAndView.addObject("msg", "傳入?yún)?shù)格式不正確：" + e.getMessage());
return modelAndView;
}
/**
*
* @desc 移動(dòng)端接口請(qǐng)求方式不正確異常類
* @param e
* @param request
* @param response
* @return
*/
@ExceptionHandler(HttpRequestMethodNotSupportedException.class)
public ModelAndView httpRequestMethodNotSupportedException(HttpRequestMethodNotSupportedException e, HttpServletRequest request, HttpServletResponse response) {
ModelAndView modelAndView = new ModelAndView(new MappingJackson2JsonView());
modelAndView.addObject("code", MobileCode.HTTP_REQUEST_METHOD_CODE);
modelAndView.addObject("msg", "請(qǐng)求方式不正確：" + e.getMessage());
return modelAndView;
}
}
