这篇文章主要介绍了JAVA错误类结果类和分页结果类代码详解,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
代码如下
public interface ErrorCode { String getCode(); String getMsg(); /** * 公共错误码<br/> * 码段：10000~10099 * * */ public enum CommonError implements ErrorCode { SUCCESS("0", "success"), UNKNOWN_ERROR("10000", "未知错误"), SYSTEM_ERROR("10001", "系统内部处理异常[%s]"), REQUEST_ERROR("10002", "请求地址或参数错误"), DB_PROCESS_FAILED("10003", "数据库处理失败"), DATA_NOT_FOUND("10004", "数据不存在"), PARAM_REQUIRED("10005", "参数为空[%s]"); private String code; private String msg; private CommonError(String code, String msg) { this.code = code; this.msg = msg; } @Override public String getCode() { return this.code; } @Override public String getMsg() { return this.msg; } public ErrorCode setParams(Object... params) { this.msg = String.format(this.msg, params); return this; } } /** * 接口错误码<br/> * 码段：10100~10199 * */ public enum ApiError implements ErrorCode { REQUEST_EMPTY("10100", "请求数据为空"), API_NOT_EXISTS("10102", "接口不存在"); private String code; private String msg; private ApiError(String code, String msg) { this.code = code; this.msg = msg; } @Override public String getCode() { return this.code; } @Override public String getMsg() { return this.msg; } }}
ErrorCode error = CommonError.SYSTEM_ERROR.setParams(e.getCause().getMessage());
Result:
public class Result<T> { public static final String SUCCESS = "0"; public static final String SCUCESS_MSG = "success"; private String result = SUCCESS; private String msg = SCUCESS_MSG; private T data; public Result() {} public Result(ErrorCode error, Object... msgParams) { this.setError(error, msgParams); } public Result(ErrorCode error) { this.setError(error); } public void setError(ErrorCode error, Object... msgParams) { this.result = error.getCode(); this.msg = error.getMsg(); if (msgParams != null && msgParams.length > 0) { this.msg = String.format(msg, msgParams); } } public void setError(ErrorCode error) { this.setError(error, new Object[] {}); } public String getResult() { return result; } public void setResult(String result) { this.result = result; } public String getMsg() { return msg; } public void setMsg(String msg) { this.msg = msg; } public T getData() { return data; } public void setData(T data) { this.data = data; } public boolean isSuccess() { return SUCCESS.equals(result); } @Override public String toString() { return "Result [result=" + result + ", msg=" + msg + ", data=" + data + "]"; }}
PageResult:
public class PageResult<T> { public static final String SUCCESS = "0"; public static final String SCUCESS_MSG = "success"; private String result = SUCCESS; private String msg = SCUCESS_MSG; private Integer total = 0; private List<T> rows = new ArrayList<>(); public PageResult() {} public PageResult(ErrorCode error, Object... msgParams) { this.setError(error, msgParams); } public PageResult(ErrorCode error) { this.setError(error); } public String getResult() { return result; } public void setResult(String result) { this.result = result; } public String getMsg() { return msg; } public void setMsg(String msg) { this.msg = msg; } public Integer getTotal() { return total; } public void setTotal(Integer total) { this.total = total; } public List<T> getRows() { return rows; } public void setRows(List<T> rows) { this.rows = rows; } public void setError(ErrorCode error, Object... msgParams) { this.result = error.getCode(); this.msg = error.getMsg(); if (msgParams != null && msgParams.length > 0) { this.msg = String.format(msg, msgParams); } } public void setError(ErrorCode error) { this.setError(error, new Object[] {}); } public boolean isSuccess() { return SUCCESS.equals(result); }}
