Swagger和knife4j
1-swagger
1.1-pom.xml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>
1.2-配置类SwaggerConfiguration.java
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.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
@Configuration
@EnableSwagger2
public class SwaggerConfiguration {
@Bean
public Docket buildDocket() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
//为当前包下controller生成API文档
.apis(RequestHandlerSelectors.basePackage("cn.ztuo.swagger"))
//为有@Api注解的Controller生成API文档
// .apis(RequestHandlerSelectors.withClassAnnotation(Api.class))
//为有@ApiOperation注解的方法生成API文档
// .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
Contact contact = new Contact("ztuo","","");
return new ApiInfoBuilder()
.title("SwaggerUI演示")
.description("SwaggerUI测试")
.contact(contact)
.version("1.0.0").build();
}
}
1.3-数据准备Person.java
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
@Data
public class Person {
@ApiModelProperty("person-id")
private String id;
@ApiModelProperty("person-name")
private String name;
@ApiModelProperty("person-age")
private int age;
@ApiModelProperty("person-address")
private String address;
}
1.4-数据准备User.java
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
@Data
public class User {
@ApiModelProperty(value="姓名",required = true)
private String name;
@ApiModelProperty(value="年龄",required = true)
private String age;
}
1.5-测试
启动admin微服务,访问地址:http://host:port/swagger-ui.html
package cn.ztuo.swagger.controller;
import cn.ztuo.swagger.pojo.Person;
import cn.ztuo.swagger.pojo.User;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.*;
@Api(value="swagger-test",tags="channer",description = "swagger测试Api")
@RestController
@RequestMapping("/swagger")
public class SwaggerController {
@ApiOperation("访问person测试")
@GetMapping("/person")
public Person test(){
Person p=new Person();
p.setId("001");
p.setAddress("紫荆城");
p.setName("老八");
p.setAge(32);
return p;
}
@ApiOperation("带参访问person测试")
@PostMapping("/person2")
public Person test1(@RequestBody User user){
System.out.println(user);
Person p=new Person();
p.setId("002");
p.setAddress("驻马店");
p.setName("六六六");
p.setAge(32);
return p;
}
}
2-Swagger常用注解
在Java类中添加Swagger的注解即可生成Swagger接口文档,常用Swagger注解如下:
@Api:修饰整个类,描述Controller的作用 @ApiOperation:描述一个类的一个方法,或者说一个接口 @ApiParam:单个参数的描述信息
@ApiModel:用对象来接收参数
@ApiModelProperty:用对象接收参数时,描述对象的一个字段
@ApiResponse:HTTP响应其中1个描述
@ApiResponses:HTTP响应整体描述
@ApiIgnore:使用该注解忽略这个API
@ApiError :发生错误返回的信息
@ApiImplicitParam:一个请求参数
@ApiImplicitParams:多个请求参数的描述信息
@ApiImplicitParam属性:
属性 | 取值 | 作用 |
---|---|---|
paramType | 查询参数类型 | |
path | 以地址的形式提交数据 | |
query | 直接跟参数完成自动映射赋值 | |
body | 以流的形式提交 仅支持POST | |
header | 参数在request headers 里边提交 | |
form | 以form表单的形式提交 仅支持POST | |
dataType | 参数的数据类型 只作为标志说明,并没有实际验证 | |
Long | ||
String | ||
name | 接收参数名 | |
value | 接收参数的意义描述 | |
required | 参数是否必填 | |
true | 必填 | |
false | 非必填 | |
defaultValue | 默认值 |
3-knife4j
3.1-pom.xml依赖
<dependency>
<groupId>com.github.xiaoymin</groupId>
<artifactId>knife4j-spring-boot-starter</artifactId>
<version>3.0.2</version>
</dependency>
3.2-配置类Swagger2Configuration.java
import com.github.xiaoymin.knife4j.spring.annotations.EnableKnife4j;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import springfox.bean.validators.configuration.BeanValidatorPluginsConfiguration;
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;
@Configuration
@EnableSwagger2
@EnableKnife4j
@Import(BeanValidatorPluginsConfiguration.class)
public class Swagger2Configuration {
@Bean(value = "defaultApi2")
public Docket defaultApi2() {
Docket docket=new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
//分组名称
.groupName("1.0")
.select()
//这里指定Controller扫描包路径
.apis(RequestHandlerSelectors.basePackage("cn.ztuo.swagger"))
.paths(PathSelectors.any())
.build();
return docket;
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("API文档测试")
.description("API文档")
.version("1.0")
.build();
}
}
3.3-knife4j说明
以上有两个注解需要特别说明,如下表:
注解 | 说明 |
---|---|
@EnableSwagger2 |
该注解是Springfox-swagger框架提供的使用Swagger注解,该注解必须加 |
@EnableKnife4j |
该注解是knife4j 提供的增强注解,Ui提供了例如动态参数、参数过滤、接口排序等增强功能,如果你想使用这些增强功能就必须加该注解,否则可以不用加 |
3.4-测试
测试类同Swagger,注解同Swagger
