springboot集成swagger3
swagger3的springboot启动器jar包
<!-- https://mvnrepository.com/artifact/io.springfox/springfox-boot-starter -->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-boot-starter</artifactId>
<version>3.0.0</version>
</dependency>注意：当前SpringBoot版本为2.5.6，Swagger3.0目前无法完全兼容SpringBoot2.6.x！
编写TestController代码
@RestController
@RequestMapping("test")
public class TestController {
@GetMapping
public Map<String, Object> get(@RequestParam String id) {
Map<String, Object> r = new HashMap<>(1);
r.put("id", id);
return r;
}
@PostMapping
public Map<String, Object> post() {
Map<String, Object> r = new HashMap<>(1);
r.put("code", 200);
return r;
}
@PutMapping
public Map<String, Object> put(String id) {
Map<String, Object> r = new HashMap<>(1);
r.put("id", id);
return r;
}
@DeleteMapping
public Map<String, Object> delete(String id) {
Map<String, Object> r = new HashMap<>(1);
r.put("id", id);
return r;
}
}
创建Swagger3Configuration
@Configuration
@EnableOpenApi
public class SwaggerConfig {
private static final String VERSION = "0.0.1";
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.OAS_30)
.groupName("分组名称")
.apiInfo(apiInfo())
.select()
//要扫描的包
.apis(RequestHandlerSelectors.basePackage("com.example.swagger.controller"))
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
// 设置标题
.title("文档标题")
//联系人
.contact(contact())
//描述
.description("xxx文档")
//服务
.termsOfServiceUrl("https://spring.io/")
//许可证
.license("Apache 2.0")
.licenseUrl("https://www.apache.org/licenses/LICENSE-2.0")
.version(VERSION)
.build();
}
private Contact contact (){
return new Contact("SpringBoot", "https://spring.io/", "email");
}
}

对接口进行注解
swagger中常用的注解
| 注解 | 作用 | 使用位置 |
|---|---|---|
| @Api | 表示对类的说明常用参数 | 类 |
| @ApiOperation | 说明方法的用途 | 方法 |
| @ApiImplicitParams | 里面可以包含多个@ApiImplicitParam | 方法 |
| @ApiImplicitParam | 描述参数的用途 | 方法 |
| @ApiModel | 表示一个数据类的信息 | 类 |
| @ApiModelProperty | 描述数据类的属性 | 属性 |
| @ApiIgnore | 忽略某个字段使之不显示在文档中 | 属性 |
接口基本使用
1.新建一个用户实体类
@ApiModel("用户")
@Data
public class User {
@ApiModelProperty("用户名")
private String username;
@ApiModelProperty("密码")
private String password;
}
2.给TestController添加注解
@Api(tags = "测试接口")
@RestController
@RequestMapping("test")
public class TestController {
@ApiOperation("get请求")
@GetMapping
@ApiImplicitParam(name = "id", value = "测试用id", dataTypeClass = String.class)
public Map<String, Object> get(@RequestParam String id) {
Map<String, Object> r = new HashMap<>(1);
r.put("id", id);
return r;
}
@ApiOperation("post请求")
@PostMapping
public Map<String, Object> post(@RequestBody User user) {
Map<String, Object> r = new HashMap<>(1);
r.put("code", 200);
return r;
}
@ApiOperation("put请求")
@PutMapping
@ApiImplicitParam(name = "id", value = "put请求id", dataTypeClass = String.class)
public Map<String, Object> put(String id) {
Map<String, Object> r = new HashMap<>(1);
r.put("id", id);
return r;
}
@ApiOperation("delete请求")
@DeleteMapping
@ApiImplicitParam(name = "id", value = "delete请求id", dataTypeClass = String.class)
public Map<String, Object> delete(String id) {
Map<String, Object> r = new HashMap<>(1);
r.put("id", id);
return r;
}
}
运行结果
集成更好的UI-knife4j
maven
<dependency> <groupId>com.github.xiaoymin</groupId> <artifactId>knife4j-micro-spring-boot-starter</artifactId> <version>3.0.3</version> </dependency>
启动器
在SwaggerConfig类上添加**@EnableKnife4j**
@Configuration @EnableOpenApi @EnableKnife4j public class SwaggerConfig
