1 导入需要的jar包
io.springfox springfox-swagger2 2.9.2 io.springfox springfox-swagger-ui 2.9.2 org.springframework.boot spring-boot-starter-web
2.整合swagger2
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
/**
* @author Administrator
* @create 2018-09-12 15:16
**/
@Configuration
@EnableSwagger2
public class Swagger2 {
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("com.sungrow.modular.marchine.controller"))
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("springboot利用swagger构建api文档")
.description("简单优雅的restfun风格")
.termsOfServiceUrl("xxx")
.version("2.9.2")
.build();
}
}3.封装基本请求参数对象
import com.alibaba.druid.util.StringUtils; import io.swagger.annotations.ApiModel; import io.swagger.annotations.ApiModelProperty; import lombok.Data; import javax.validation.Valid; import javax.validation.constraints.NotNull; /** * @author shihaifeng * @date 2019-07-29 8:54 * @desc 请求头的基础参数 **/ @ApiModel @Data public class RequestBaseParam{ /** * 用户定位区域编码 */ /*@NotNull(message = "area不能为空") @Length(min = 6, max = 6, message = "area长度为6") @ApiModelProperty(value = "用户定位区域编码") private String area;*/ /** * 提交的数据进行base64签名，针对敏感接口（支付）采用对称加密算法进行加密 */ /*@ApiModelProperty(value = "data") private String data;*/ /** * 客户端根据一定规则生成的md5验证码，以保证数据访问的安全性； Sign值32位，不为空 */ // @NotNull(message = "sign不能为空") // @Length(min = 32, max = 32, message = "sign长度为32") @ApiModelProperty(value = "sign") private String sign; /** * 时间戳：客户端生成加密值时的时间戳；加一位设备类型 时间戳（13位）+设备类型（1位）共14位，不为空 */ // @NotNull(message = "tt不能位空") // @Length(min = 14, max = 14, message = "tt长度为14") @ApiModelProperty(value = "时间戳") private String tt; /** * 登录用户ID， 可为空 */ @NotNull(message = "登录用户ID不能为空") @ApiModelProperty(value = "登录用户ID") private Integer uid; /** * 泛型：自定义请求参数实体对象 * 嵌套验证必须用 @Valid */ @Valid @NotNull(message = "自定义参数必传") private T t; public String transfer(){ StringBuilder builder = new StringBuilder(); if(!StringUtils.isEmpty(tt)){ builder.append("tt=").append(tt).append("&"); } if(uid != null){ builder.append("uid=").append(uid).append("&"); } return builder.toString(); } }
4.使用aop拦截异常
package com.sungrow.common.exception;
import com.sungrow.common.api.ResultBaseEntity;
import org.springframework.http.HttpStatus;
import org.springframework.validation.BindException;
import org.springframework.validation.BindingResult;
import org.springframework.validation.FieldError;
import org.springframework.web.bind.MethodArgumentNotValidException;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseStatus;
import org.springframework.web.bind.annotation.RestControllerAdvice;
/**
* @author shihaifeng
* @date 2019-07-29 16:41
* @desc 用来处理参数绑定绑定异常的全局处理器
**/
@RestControllerAdvice
public class BizExceptionHandler {
/**
* 接收 表单 提交过来的异常，返回给客户端json格式
*
* @param e
* @return
*/
@ExceptionHandler(BindException.class)
@ResponseStatus(HttpStatus.BAD_REQUEST)
public ResultBaseEntity bindException(BindException e) {
ResultBaseEntity resultBaseEntity = new ResultBaseEntity<>();
BindingResult bindingResult = e.getBindingResult();
String errorMesssage = "校验失败: ";
for (FieldError fieldError : bindingResult.getFieldErrors()) {
errorMesssage += fieldError.getDefaultMessage() + ", ";
}
/**
* 把错误结果集封装给客户
*/
resultBaseEntity.setResult_code("400");
resultBaseEntity.setResult_msg(errorMesssage);
return resultBaseEntity;
}
/**
* 拦击json提交过来的参数绑定异常，返回给客户端json格式
* @param e
* @return
*/
@ExceptionHandler(MethodArgumentNotValidException.class)
@ResponseStatus(HttpStatus.BAD_REQUEST)
public ResultBaseEntity myMethodArgumentNotValidException(MethodArgumentNotValidException e){
ResultBaseEntity resultBaseEntity = new ResultBaseEntity<>();
BindingResult bindingResult = e.getBindingResult();
String errorMesssage = "josn校验失败: ";
for (FieldError fieldError : bindingResult.getFieldErrors()) {
errorMesssage += fieldError.getDefaultMessage() + ", ";
}
resultBaseEntity.setResult_code("400");
resultBaseEntity.setResult_msg(errorMesssage);
return resultBaseEntity;
}
} 4.增加返回对象封装
package com.sungrow.common.api; import io.swagger.annotations.ApiModel; import io.swagger.annotations.ApiModelProperty; import lombok.Data; import java.io.Serializable; /** * @author shihaifeng * @date 2019-07-31 19:04 * @desc (返回封装结果集) **/ @ApiModel(value = "返回封装结果集") @Data public class ResultBaseEntityimplements Serializable { @ApiModelProperty(value = "结果集编码，1：成功") private String result_code ; @ApiModelProperty(value = "结果集消息") private String result_msg ; @ApiModelProperty(value = "返回类") private T t ; }
快速返回结果集工具
package com.sungrow.common.api;
import com.sungrow.common.constant.ErrCodeEnum;
/**
* @author shihaifeng
* @date 2019-08-01 11:44
* @desc (用来快速返回结果集)
**/
public class JsonResult {
public static ResultBaseEntity success() {
return result(ErrCodeEnum.ERR_CODE_1.getErrCode(), null, ErrCodeEnum.ERR_CODE_1.getErrMsg());
}
public static ResultBaseEntity success(T data) {
return result(ErrCodeEnum.ERR_CODE_1.getErrCode(), data, ErrCodeEnum.ERR_CODE_1.getErrMsg());
}
public static ResultBaseEntity success(ErrCodeEnum iCode) {
return result(iCode.getErrCode(), null, iCode.getErrMsg());
}
public static ResultBaseEntity success(ErrCodeEnum iCode, Object data) {
return result(iCode.getErrCode(), data, iCode.getErrMsg());
}
public static ResultBaseEntity error(ErrCodeEnum iCode) {
return error(iCode, null);
}
public static ResultBaseEntity error(ErrCodeEnum iCode, T data) {
return result(iCode.getErrCode(), data, iCode.getErrMsg());
}
public static ResultBaseEntity error(ErrCodeEnum iCode, T data, String message) {
return result(iCode.getErrCode(), data, message);
}
/**
* @param code 返回码
* @param data
* @param message
* @return
*/
public static ResultBaseEntity result(String code, T data, String message) {
ResultBaseEntity ResultBaseEntity = new ResultBaseEntity();
ResultBaseEntity.setResult_code(code);
ResultBaseEntity.setResult_msg(message);
if (data != null) {
ResultBaseEntity.setT(data);
}
return ResultBaseEntity;
}
} 5.测试接口
