1、介绍
swagger是一个在线接口说明文档,在代码中通过注解的方式将说明问题集成到项目,代码发生修改,说明文档同步修改,前后台联调可以快速同步数据。
2、应用
1、引入依赖
<dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger2</artifactId><version>2.9.2</version> </dependency> <dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger-ui</artifactId><version>2.9.2</version> </dependency>
2、编写配置类
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; /*** @author szsw* @date 2023/3/1 18:12:17*/ @Configuration public class SwaggerConfig { @Beanpublic Docket docket() {/*采用swagger2版本*/return new Docket(DocumentationType.SWAGGER_2)/*生成api相关信息*/.apiInfo(createApiInfo())/*返回一个apiSelectorBuilder对象,用来控制接口生成在线文档*/.select()/*扫描某个包下的接口*/.apis(RequestHandlerSelectors.basePackage("org.jsoft.demo.controller"))/*生成所有的api*/.paths(PathSelectors.any()).build();} /*** 创建api相关信息** @return ApiInfo*/private ApiInfo createApiInfo() {return new ApiInfoBuilder()/*自定义title*/.title("swagger demo")/*描述*/.description("swagger示例")/*定义服务域名*/.termsOfServiceUrl("")/*自定义版本号*/.version("0.0.1").build();} }
3、开启Swagger
@EnableSwagger2 启动器
4、编写示例
1、实体类
package org.jsoft.demo.dto; import io.swagger.annotations.ApiModel; import io.swagger.annotations.ApiModelProperty; import lombok.Data; import java.util.Date; @Data @ApiModel public class UserUpdateDto { @ApiModelProperty(value = "主键", required = true, example = "asdfa54s56d")private String id;@ApiModelProperty(value = "名字", required = true, example = "张三")private String name;@ApiModelProperty(value = "密码", required = true, example = "123456")private String password;@ApiModelProperty(value = "年龄", required = true, example = "20")private Integer age;@ApiModelProperty(value = "生日", required = true, example = "1998-07-07")private Date birthday;@ApiModelProperty(value = "分数", example = "100.5")private Double score; } /* value 描述 required 必填项 example 举例 */ package org.jsoft.demo.dto; import io.swagger.annotations.ApiModel; import io.swagger.annotations.ApiModelProperty; import lombok.Data; import java.util.Date; @Data @ApiModel public class UserAddDto { @ApiModelProperty(value = "名字", required = true, example = "张三")private String name;@ApiModelProperty(value = "密码", required = true, example = "123456")private String password;@ApiModelProperty(value = "年龄", required = true, example = "20")private Integer age;@ApiModelProperty(value = "生日", required = true, example = "1998-07-07")private Date birthday;@ApiModelProperty(value = "分数", example = "100.5")private Double score; }
2、Controller
package org.jsoft.demo.controller; import io.swagger.annotations.Api; import io.swagger.annotations.ApiImplicitParam; import io.swagger.annotations.ApiImplicitParams; import io.swagger.annotations.ApiOperation; import org.jsoft.demo.dto.UserAddDto; import org.jsoft.demo.dto.UserUpdateDto; import org.jsoft.demo.utils.Result; import org.springframework.web.bind.annotation.*; import springfox.documentation.annotations.ApiIgnore; import java.util.Map; @Api(tags = "用户") @RestController @RequestMapping("/user") public class UserController { @PostMapping@ApiOperation("用户新增")public Result add(@RequestBody UserAddDto dto) {return Result.ok();} @DeleteMapping("/{id}")@ApiOperation("用户删除")@ApiImplicitParams({@ApiImplicitParam(value = "删除的用户主键", name = "id", paramType = "path")})public Result delete(@PathVariable String id) {return Result.ok();} @PutMapping@ApiOperation("用户修改")public Result update(@RequestBody UserUpdateDto dto) {return Result.ok();} @GetMapping("/{id}")@ApiOperation("用户详情")@ApiImplicitParams({@ApiImplicitParam(value = "用户主键", paramType = "path") //path是指地址传参。})public Result info(@PathVariable String id) {return Result.ok();} @GetMapping@ApiOperation("用户查询")@ApiImplicitParams({@ApiImplicitParam(value = "姓名", name = "name", paramType = "query"),@ApiImplicitParam(value = "年龄", name = "age", paramType = "query"),@ApiImplicitParam(value = "分数", name = "score", paramType = "query") // get地址栏传参})public Result query(@ApiIgnore @RequestParam Map<String, String> params) {return Result.ok();} }
3、访问地址
http:localhost:100/swagger-ui.html 100端口号
