在使用springboot过程中,一般都会设置全局异常管理,如下:

import com.yzf.enterprise.market.common.constant.HttpStatus;
import com.yzf.enterprise.market.common.exception.BaseException;
import com.yzf.enterprise.market.common.exception.CustomException;
import com.yzf.enterprise.market.common.exception.DemoModeException;
import com.yzf.enterprise.market.common.utils.StringUtils;
import com.yzf.enterprise.market.framework.web.domain.AjaxResult;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.security.access.AccessDeniedException;
import org.springframework.security.authentication.AccountExpiredException;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.validation.BindException;
import org.springframework.web.bind.MethodArgumentNotValidException;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RestControllerAdvice;
import org.springframework.web.servlet.NoHandlerFoundException;

/**
 * 全局异常处理器
 */
@RestControllerAdvice
public class GlobalExceptionHandler {
    private static final Logger log = LoggerFactory.getLogger(GlobalExceptionHandler.class);

    /**
     * 基础异常
     */
    @ExceptionHandler(BaseException.class)
    public AjaxResult baseException(BaseException e) {
        return AjaxResult.error(e.getMessage());
    }

    /**
     * 业务异常
     */
    @ExceptionHandler(CustomException.class)
    public AjaxResult businessException(CustomException e) {
        if (StringUtils.isNull(e.getCode())) {
            return AjaxResult.error(e.getMessage());
        }
        return AjaxResult.error(e.getCode(), e.getMessage());
    }

    @ExceptionHandler(NoHandlerFoundException.class)
    public AjaxResult handlerNoFoundException(Exception e) {
        log.error(e.getMessage(), e);
        return AjaxResult.error(HttpStatus.NOT_FOUND, "路径不存在,请检查路径是否正确");
    }

    @ExceptionHandler(AccessDeniedException.class)
    public AjaxResult handleAuthorizationException(AccessDeniedException e) {
        log.error(e.getMessage());
        return AjaxResult.error(HttpStatus.FORBIDDEN, "没有权限,请联系管理员授权");
    }
}

这样在系统报错的时候,就能将异常格式化输出到前端,对前端非常友好。但是过滤器中的异常通过这种方式是解决不了的,可以通过以下方式解决:

import org.springframework.boot.autoconfigure.web.ErrorProperties;
import org.springframework.boot.autoconfigure.web.servlet.error.BasicErrorController;
import org.springframework.boot.web.servlet.error.DefaultErrorAttributes;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;
import java.util.Map;

@RestController
public class TokenErrorController extends BasicErrorController {

    public TokenErrorController() {
        super(new DefaultErrorAttributes(), new ErrorProperties());
    }

    @Override
    @RequestMapping(produces = {MediaType.APPLICATION_JSON_VALUE})
    public ResponseEntity<Map<String, Object>> error(HttpServletRequest request) {
        Map<String, Object> body = getErrorAttributes(request, isIncludeStackTrace(request, MediaType.ALL));
        HttpStatus status = getStatus(request);
        return new ResponseEntity((String) body.get("message"), status);
    }
}

可以按照自定义的格式定义过滤器异常返回的数据格式。
