spring異常處理@ControllerAdvice

1.自定義異常

package com.xxx.finance.common.exception;

/**

 */
public abstract class FinanceException extends RuntimeException {

    protected FinanceException(Integer exceptionCode, ExceptionGrade exceptionGrade, String message) {
        if (exceptionGrade != null) {

            this.exceptionCode = exceptionCode;
        }

    }

    }

    public void setMessage(String message) {

}

package com.xxx.finance.common.exception;

/**

 */

    public FinanceExceptionService(String exceptionCode, ExceptionGrade exceptionGrade) {
        super(Integer.valueOf(exceptionCode), exceptionGrade, null);
    }
}

2.返回值基類

package com.xxx.finance.common.model;

import org.apache.commons.lang.builder.*;

/**
 * Created by xdc on 2016/8/3 15:32.
 */
public class ResponseHeaderModel {

    protected long time=System.currentTimeMillis();
    protected String message="SUCCESS";
    protected Integer code = 0;

    public ResponseHeaderModel() {
        super();
    }

    public ResponseHeaderModel(long time,String message, Integer code) {
        this.time=time;
        this.message = message;
        this.code = code;
    }

    public long getTime() {
        return time;
    }

    public String getMessage() {
        return message;
    }

    public Integer getCode() {
        return code;
    }
    public void setCode(Integer code) {
        this.code = code;
    }

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

    public String toString() {
        return ToStringBuilder.reflectionToString(this);
    }
}

package com.xxx.finance.common.model;

import com.xxx.finance.common.exception.*;
import net.sf.json.*;

/**
 * Created by xdc on 2016/8/3 15:32.
 */
public class ResponseModel extends ResponseHeaderModel {
    private Object data;

    public ResponseModel() {
        super();
        super.time = System.currentTimeMillis();
    }

    public ResponseModel(Object data) {
        this.data = data;
        super.time = System.currentTimeMillis();

    }

    public ResponseModel(int code, String massage) {
        super.code = code;
        super.message = massage;
        super.time = System.currentTimeMillis();
    }

    public Object getData() {
        return data;
    }

    public void setData(Object data) {
        this.data = data;
        super.time = System.currentTimeMillis();
    }

    public static ResponseModel successResult() {
        ResponseModel ro = new ResponseModel();
        ro.setCode(ResultCode.codeSuccess);
        ro.setMessage(ResultCode.massageSuccess);
        return ro;
    }

    public static ResponseModel errorResult() {
        ResponseModel ro = new ResponseModel();
        ro.setCode(ResultCode.codeError);
        ro.setMessage(ResultCode.massageError);
        return ro;
    }

    @Override
    public String toString() {

        JSONObject jsonObject = new JSONObject();
        jsonObject.put("code", code);
        jsonObject.put("message", message);
        jsonObject.put("data", data);

        return jsonObject.toString();
    }
}

3.異常攔截類

package com.xxx.finance.interceptor;

import com.xxx.finance.common.exception.*;
import com.xxx.finance.common.model.*;
import org.springframework.web.bind.annotation.*;

/**
 * 異常攔截類
 * Created by xdc on 2016/8/3 15:25.
 */
@ControllerAdvice
public class ExceptionHandler {

    @ResponseBody
    @org.springframework.web.bind.annotation.ExceptionHandler(Exception.class)
    public ResponseModel handleUnexpectedServerError(Exception ex) {
        ex.printStackTrace();

        // 處理異常
        ResponseModel response = new ResponseModel();

        String errorMsg = ex.getMessage();
        response.setCode(Integer.valueOf(ResultCode.SYSTEM_EXCEPTION));
        if(errorMsg.contains("excpStart")){
            errorMsg = errorMsg.substring(errorMsg.indexOf("excpStart") + 9, errorMsg.indexOf("excpEnd"));
        }
        response.setMessage(errorMsg);

        // 返回數據
        return response;
    }

}

4.前端獲取異常

if(confirm("確認作廢？")){
            $.ajax({
                type : "POST",
                url : "../invoice/cancelInvoice?ran="+Math.random(),
                data : {
                    id : id,
                    timestamp : lastChangedDate
                },
                cache : false,
                async : true,
                error : function(XMLHttpRequest, textStatus, errorThrown) {
                    $.globalMessenger().post({
                        message : "系統異常，請聯繫管理員！",
                        type : "error"
                    });
                },
                success : function(res) {
                    if (res && res.code == 0) {
                        showMsg("發票作廢成功");
                    }else{
                        showMsg(res.message, "error");
                    }
                }
            });
        }

5.異常測試

throw new FinanceExceptionService("3", "異常測試");

（另一個項目異常處理備份）

1.自定義異常

package com.xx.cloud.assets.common.exception;

import org.slf4j.*;

import com.xx.cloud.assets.common.constant.ResponseCode;

/**
 * xx管理exception

public class AssetException extends Exception {
    protected Logger logger = LoggerFactory.getLogger(this.getClass());

    private Integer exceptionCode = 0;
    private String message = null;

   
    private static final long serialVersionUID = 1L;

    public AssetException() {
        super();
    }

    public AssetException(Integer exceptionCode, String message) {
        if (exceptionCode != null) {
            this.exceptionCode = exceptionCode;
        }
        this.message = message;
    }

    public AssetException(ResponseCode responseCode) {
        this.exceptionCode = responseCode.getCode();
        this.message = responseCode.getMessage();
    }


    public AssetException(String message) {
        this.message = message;
    }

    public Integer getExceptionCode() {
        return exceptionCode;
    }

    public void setExceptionCode(Integer exceptionCode) {
        this.exceptionCode = exceptionCode;
    }

    public String getMessage() {
        return message;
    }

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

}

2.異常代碼

package com.xx.cloud.assets.common.constant;


public enum ResponseCode {



    /**

     */
    SUCCESS(0, "操作成功！"),

    UNKONW_ERROR(-1,"未知錯誤！"),

     */
    LOGOUT_ERROR(3, "登出失敗！"),

    NO_READ_PERMISSION(59001,"該資產非本公司資產，無權限查看!"),

    NO_WRITE_PERMISSION(59003,"無權操作!"),

    PARAM_ERROR(59002,"參數錯誤"),
    UNAUTHENTICATION(50003, "認證失敗，請重新登錄"),

    UNAUTHORIZATION(60001, "權限驗證失敗，請聯繫管理員");

    /** 返回狀態code */
    private Integer code = 0;

    /** 狀態描述 */
    private String message = null;

    private ResponseCode(Integer code, String message) {
        this.code = code;
        this.message = message;
    }

    public Integer getCode() {
        return code;
    }

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

    public String getMessage() {
        return message;
    }

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

    public static ResponseCode fromValue(Integer code) {
        for (ResponseCode field : values()) {
            if (field.code == code) {
                return field;
            }
        }
        return null;
    }
}
