【Swagger学习入门】展示使用教程

这里简单说一下Swagger的作用：跟Postman、Eolinker都是用于数据测试

SpringBoot集成Swagger

1. 新建SpringBoot项目，导入swagger依赖

 <!--swagger依赖-->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.9.2</version>
</dependency>
<!--swagger ui-->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>2.9.2</version>
</dependency>

2. 编写swagger的配置文件

• 选择需要暴露在Swagger页面的接口
• 填写生成Swagger页面时的一些展示信息

@Configuration
@EnableSwagger2
public class Swagger2Config {
    @Bean
    public Docket coreApiConfig(){
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(adminApiInfo())	// apiInfo() 增加API相关信息
                .groupName("adminApi")		// groupName() 增加分组组名信息
                .select()					// select() 用来控制哪些接口暴露给Swagger来展现
                .paths(Predicates.and(PathSelectors.regex("/admin/.*")))	//只显示admin下面的路径
                .build();
    }

    private ApiInfo adminApiInfo(){
        return new ApiInfoBuilder()
                .title("尚融宝后台管理系统--api文档")
                .description("尚融宝后台管理系统接口描述")
                .version("1.0")
                .contact(new Contact("李燕茹","http://baidu.com","[email protected]"))
                .build();
    }
}

3. 编写实体类

//实体类
//entity的实体类中可以添加一些自定义设置
@Data
@EqualsAndHashCode(callSuper = false)
@ApiModel(value="IntegralGrade对象", description="积分等级表")
public class IntegralGrade implements Serializable {

    private static final long serialVersionUID = 1L;

    @ApiModelProperty(value = "编号")
      @TableId(value = "id", type = IdType.AUTO)
    private Long id;

    @ApiModelProperty(value = "积分区间开始")
    private Integer integralStart;

    @ApiModelProperty(value = "积分区间结束")
    private Integer integralEnd;

    @ApiModelProperty(value = "借款额度")
    private BigDecimal borrowAmount;

    @ApiModelProperty(value = "创建时间")
    private LocalDateTime createTime;

    @ApiModelProperty(value = "更新时间")
    private LocalDateTime updateTime;

    @ApiModelProperty(value = "逻辑删除(1:已删除，0:未删除)")
    @TableField("is_deleted")
    @TableLogic
    private Boolean deleted;
}

4. 编写Controller

@RestController
@RequestMapping("/admin/integralGrade")
@Api(value = "积分等级管理")
public class IntegralGradeController {

    @Resource
    private IntegralGradeService integralGradeService;

    @GetMapping("/list")
    @ApiOperation("积分等级列表")		//API接口信息描述
    public Result listAll(){
        List<IntegralGrade> list = integralGradeService.list();
        return Result.ok().data("list",list);
    }

    @DeleteMapping("/remove/{id}")
    @ApiOperation(value = "根据id删除积分等级",notes = "逻辑删除")
    public Result removeById(
        @ApiParam(value = "数据id",required = true,example = "1")
        @PathVariable Long id){
        boolean result = integralGradeService.removeById(id);
        if (result){
            return Result.ok().message("删除成功");
        }else {
            return Result.error().message("删除失败");
        }
    }

    @PostMapping("/save")
    @ApiOperation(value = "新增积分等级")
    public Result save(@ApiParam(value = "积分等级对象",required = true) @RequestBody IntegralGrade integralGrade){
        boolean result = integralGradeService.save(integralGrade);
        if (result){
            return Result.ok().message("新增成功");
        }else {
            return Result.error().message("新增失败");
        }
    }

    @PutMapping("/updateById")
    @ApiOperation(value = "根据id修改积分等级")
    public Result updateById(@ApiParam(value = "积分等级对象",required = true) @RequestBody IntegralGrade integralGrade){
        boolean result = integralGradeService.updateById(integralGrade);
        if (result){
            return Result.ok().message("修改成功");
        }else {
            return Result.error().message("修改失败");
        }
    }

    @GetMapping("/getById/{id}")
    @ApiOperation(value = "根据id查询积分等级")
    public Result getById(@ApiParam(value = "数据id",required = true,example = "1") @PathVariable Long id){
        IntegralGrade result = integralGradeService.getById(id);
        if (result == null){
            return Result.error().message("查询失败");
        }else {
            return Result.ok().data("integralGrade",result);
        }
    }
}

5. 访问Swagger页面

完成上述代码，启动Spring Boot程序，访问：http://localhost:8080/swagger-ui.html

6. 功能测试
