整合swagger、knife4j

1.导入pom依赖

<properties>
    <!-- 版本统一管理-->
    <!--Swagger Resources-->
    <knife4j.version>2.0.4</knife4j.version>
    <springfox.version>2.9.2</springfox.version>
    <swagger.version>1.6.1</swagger.version>
</properties>

<dependencyManagement>
    <dependencies>
        <!--knife4j是为Java MVC框架集成Swagger生成Api文档的增强解决方案-->

SwaggerConfiguration

3.具体使用

import cn.hutool.json.JSONObject;
import com.github.xiaoymin.knife4j.annotations.ApiOperationSupport;
import com.github.xiaoymin.knife4j.annotations.ApiSort;
import com.github.xiaoymin.knife4j.annotations.DynamicParameter;
import com.github.xiaoymin.knife4j.annotations.DynamicResponseParameters;import com.pojo.exam.UserRecentExam;
import io.swagger.annotations.*;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @Author: 马家立
 * @Date: 2020/10/19 14:02
 */
@ApiSort(14)
@RestController
@RequestMapping("/userExam")
@Api(tags = "用户考试模块")
public class TUserExamController {

    @ApiOperation(value = "考试历史记录")
    @ApiResponses(value = {
            @ApiResponse(code = 200, message = "成功")
            , @ApiResponse(code = 400, message = "失败")
            , @ApiResponse(code = 500, message = "服务器出错")})
    @ApiOperationSupport(order = 1, responses = @DynamicResponseParameters(properties = {
            @DynamicParameter(value = "响应码", name = "code"),
            @DynamicParameter(value = "描述", name = "message"),
            @DynamicParameter(value = "返回结果", name = "data", dataTypeClass = UserRecentExam.class)// 配置返回结果类
    }))
    @ApiImplicitParam(name = "userId", value = "用户id", required = true, dataType = "Long")
    @PostMapping("/recentExamAndHistory")
    public ReturnData<Object> recentExamAndHistory(@ApiParam(hidden = true) @RequestBody JSONObject param) throws Exception {
        Long userId = param.getLong("userId");
        /**
         * 考试历史记录
         */
        return null;
    }

}

 配置返回结果类

import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

/**
 * @Author: 马家立
 * @Date: 2020/10/20 10:14
 * @Description: TODO 考试历史记录
 */
@Data
public class UserRecentExam {

    @ApiModelProperty(value = "考试试卷名称")
    private String examName;

    @ApiModelProperty(value = "平均时间")
    private double avgTime;

    @ApiModelProperty(value = "总分数")
    private double totalScore;

    @ApiModelProperty(value = "平均分")
    private Long avgScore;

    @ApiModelProperty(value = "合格率")
    private Double passRate;

}
