1.技术架构

SpringBoot+Spring Data Jpa+mysql+ES+Redis+Thymeleaf+bootstrap+jquery+H-ui admin页面模板（后台管理）

2.架构设计

3.API设计

RESTFul风格

API数据格式标准：

（1）code   自定义请求编码

（2）message     自定义请求响应信息描述

（3）data      请求目标数据

API格式封装类

public class ApiResponse \{  
    private int code;  
    private String message;  
    private Object data;  
    private boolean more;//表示数据集是否含有一些更多的信息

public ApiResponse(int code, String message, Object data) \{  
        this.code = code;  
        this.message = message;  
        this.data = data;  
    \}

public ApiResponse() \{  
        this.code = Status.SUCCESS.getCode();  
        this.message = Status.SUCCESS.getStandardMessage();  
    \}

public int getCode() \{  
        return code;  
    \}

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

public String getMessage() \{  
        return message;  
    \}

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

public Object getData() \{  
        return data;  
    \}

public void setData(Object data) \{  
        this.data = data;  
    \}

public boolean isMore() \{  
        return more;  
    \}

public void setMore(boolean more) \{  
        this.more = more;  
    \}

public static ApiResponse ofMessage(int code, String message) \{  
        return new ApiResponse(code, message, null);  
    \}

public static ApiResponse ofSuccess(Object data) \{  
        return new ApiResponse(Status.SUCCESS.getCode(), Status.SUCCESS.getStandardMessage(), data);  
    \}

public static ApiResponse ofStatus(Status status) \{  
        return new ApiResponse(status.getCode(), status.getStandardMessage(), null);  
    \}

public enum Status \{  
        SUCCESS(200, "OK"),  
        BAD\_REQUEST(400, "Bad Request"),  
        NOT\_FOUND(404, "Not Found"),  
        INTERNAL\_SERVER\_ERROR(500, "Unknown Internal Error"),  
        NOT\_VALID\_PARAM(40005, "Not valid Params"),  
        NOT\_SUPPORTED\_OPERATION(40006, "Operation not supported"),  
        NOT\_LOGIN(50000, "Not Login");

private int code;  
        private String standardMessage;

Status(int code, String standardMessage) \{  
            this.code = code;  
            this.standardMessage = standardMessage;  
        \}

public int getCode() \{  
            return code;  
        \}

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

public String getStandardMessage() \{  
            return standardMessage;  
        \}

public void setStandardMessage(String standardMessage) \{  
            this.standardMessage = standardMessage;  
        \}  
    \}

web错误全局异常类配置

@Controller  
public class AppErrorController implements ErrorController \{  
    private static final String ERROR\_PATH = "/error";

private ErrorAttributes errorAttributes;

@Override  
    public String getErrorPath() \{  
        return ERROR\_PATH;  
    \}

@Autowired  
    public AppErrorController(ErrorAttributes errorAttributes) \{  
        this.errorAttributes = errorAttributes;  
    \}

/\*\*  
     \* Web页面错误处理  
     \*/  
    @RequestMapping(value = ERROR\_PATH, produces = "text/html")  
    public String errorPageHandler(HttpServletRequest request, HttpServletResponse response) \{  
        int status = response.getStatus();  
        switch (status) \{  
            case 403:  
                return "403";  
            case 404:  
                return "404";  
            case 500:  
                return "500";  
        \}

return "index";  
    \}

/\*\*  
     \* 除Web页面外的错误处理，比如Json/XML等  
     \*/  
    @RequestMapping(value = ERROR\_PATH)  
    @ResponseBody  
    public ApiResponse errorApiHandler(HttpServletRequest request) \{  
        RequestAttributes requestAttributes = new ServletRequestAttributes(request);

Map<String, Object> attr = this.errorAttributes.getErrorAttributes(requestAttributes, false);  
        int status = getStatus(request);

return ApiResponse.ofMessage(status, String.valueOf(attr.getOrDefault("message", "error")));  
    \}

private int getStatus(HttpServletRequest request) \{  
        Integer status = (Integer) request.getAttribute("javax.servlet.error.status\_code");  
        if (status != null) \{  
            return status;  
        \}

return 500;  
    \}  
\}
