1、返回类

import java.io.Serializable;

public class ResponseInfo implements Serializable {

    private static final long serialVersionUID = -4417715614021482064L;

    private String code;
    private String message;

    public ResponseInfo(String code, String message) {
        super();
        this.code = code;
        this.message = message;
    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

}

2、异常处理类

import org.springframework.http.HttpStatus;
import org.springframework.http.converter.HttpMessageNotReadableException;
import org.springframework.security.access.AccessDeniedException;
import org.springframework.validation.ObjectError;
import org.springframework.web.bind.MissingServletRequestParameterException;
import org.springframework.web.bind.UnsatisfiedServletRequestParameterException;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseStatus;
import org.springframework.web.bind.annotation.RestControllerAdvice;
import org.springframework.web.method.annotation.MethodArgumentTypeMismatchException;
import com.xx.xx.xx.ResponseInfo;



/**
 * springmvc异常处理
 *
 */
@RestControllerAdvice
public class ExceptionHandlerAdvice {

    @ExceptionHandler({ IllegalArgumentException.class })
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    public ResponseInfo badRequestException(IllegalArgumentException exception) {
        return new ResponseInfo(HttpStatus.BAD_REQUEST.value() + "", exception.getMessage());
    }

    @ExceptionHandler({ AccessDeniedException.class })
    @ResponseStatus(HttpStatus.FORBIDDEN)
    public ResponseInfo badRequestException(AccessDeniedException exception) {
        return new ResponseInfo(HttpStatus.FORBIDDEN.value() + "", exception.getMessage());
    }

    @ExceptionHandler({ MissingServletRequestParameterException.class, HttpMessageNotReadableException.class,
            UnsatisfiedServletRequestParameterException.class, MethodArgumentTypeMismatchException.class })
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    public ResponseInfo badRequestException(Exception exception) {
        return new ResponseInfo(HttpStatus.BAD_REQUEST.value() + "", exception.getMessage());
    }
    @ExceptionHandler(org.springframework.web.bind.MethodArgumentNotValidException.class)
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    public ResponseInfo MethodArgumentNotValidException(org.springframework.web.bind.MethodArgumentNotValidException e) {
        ObjectError objectError = e.getBindingResult().getAllErrors().get(0);
        //参数检验出错
        return new ResponseInfo(HttpStatus.BAD_REQUEST.value()+"",objectError.getDefaultMessage());
    }
    
    @ExceptionHandler(Throwable.class)
    @ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
    public ResponseInfo exception(Throwable throwable) {
        //系统异常
        return new ResponseInfo(HttpStatus.INTERNAL_SERVER_ERROR.value() + "", throwable.getMessage());

    }

}
