1、首先引入jar包
<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、开启swagger,以及一些配置,参考地址
import com.google.common.base.Predicate;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.bind.annotation.RequestMethod;
import springfox.documentation.RequestHandler;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.builders.ResponseMessageBuilder;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.ResponseMessage;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
import java.util.ArrayList;
import java.util.List;
import java.util.Set;
/**
author: Administrator
*/
@Configuration
@EnableSwagger2
public class Swagger2 {
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("mybatis-plus and swagger2")
.description("mybatis-plus and swagger2 结合使用")
.termsOfServiceUrl("https://localhost:8081/")
.version("1.0.0")
.build();
}
@Bean
public Docket createRestApi() {
//可以控制 哪些符合条件的 接口 对外暴露文档;
Predicate<RequestHandler> predicate = (input) -> {
Set<String> patterns = input.getRequestMapping().getPatternsCondition().getPatterns();
for (String cur : patterns) {
//if (cur.startsWith("/api")) return true;
}
return true;
};
ResponseMessage responseMesssageSucc = new ResponseMessageBuilder()
.code(0)
.message("处理成功")
.build();
ResponseMessage responseMesssageFail = new ResponseMessageBuilder()
.code(-1)
.message("处理失败")
.build();
List<ResponseMessage> list = new ArrayList();
list.add(responseMesssageSucc);
list.add(responseMesssageFail);
return new Docket(DocumentationType.SWAGGER_2)
.useDefaultResponseMessages(false)
.globalResponseMessage(RequestMethod.POST, list)
.apiInfo(apiInfo())
.select()
.apis(predicate)
.apis(RequestHandlerSelectors.basePackage("com.example.mybatisplus.controller"))
.paths(PathSelectors.any())
.build();
}
}
3、swagger访问页面配置类:Swagger2MvcConfig
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
/**
author: Administrator
*/
@Configuration
public class Swagger2MvcConfig extends WebMvcConfigurationSupport {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/");
registry.addResourceHandler("/public/**").addResourceLocations("classpath:/public/");
registry.addResourceHandler("swagger-ui.html").addResourceLocations(
"classpath:/META-INF/resources/");
registry.addResourceHandler("/webjars/**").addResourceLocations(
"classpath:/META-INF/resources/webjars/");
}
}
4、swagger的使用,访问接口文档:localhost:8080/swagger-ui.html
用户信息实体类使用swagger注解
import com.baomidou.mybatisplus.extension.activerecord.Model;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
import lombok.EqualsAndHashCode;
import lombok.experimental.Accessors;
/**
*
*
*
*
* @author jasonwang
* @since 2020-07-30
*/
@ApiModel(value = "user",description = "用户信息表")
@Data
@EqualsAndHashCode(callSuper = true)
@Accessors(chain = true)
public class User extends Model {
private static final long serialVersionUID = 1L;
@ApiModelProperty(value = "用户id")
private Integer id;
@ApiModelProperty(value = "年龄")
private Integer age;
@ApiModelProperty(value = "姓名")
private String name;
@ApiModelProperty(value = "性别")
private String sex;
}
请求类以及请求方法上使用swagger注解
import com.example.mybatisplus.model.auto.User;
import com.example.mybatisplus.service.IUserService;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import java.util.List;
/**
*
* 前端控制器
*
*
* @author jasonwang
* @since 2020-07-30
*/
@RestController
@RequestMapping("/user")
public class UserController {
@Autowired
private IUserService userService;
@ApiOperation(value="获取用户详细信息", notes="根据id来获取用户详细信息")
@ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Integer", paramType = "path")
@GetMapping("/{id}/getUser")
public User getUser(@PathVariable int id){
return userService.getById(id);
}
@ApiOperation(value="获取所有用户信息", notes="获取所有用户信息")
@ApiImplicitParam()
@GetMapping("/findAllUser")
public List<User> findAllUser(){
return userService.findAllUser();
}
}
5、swagger2注解使用,参考地址:
@Api:用在请求的类上,表示对类的说明
tags="说明该类的作用,可以在UI界面上看到的注解"
value="该参数没什么意义,在UI界面上也看到,所以不需要配置"
@ApiOperation:用在请求的方法上,说明方法的用途、作用
value="说明方法的用途、作用"
notes="方法的备注说明"
@ApiImplicitParams:用在请求的方法上,表示一组参数说明
@ApiImplicitParam:用在@ApiImplicitParams注解中,指定一个请求参数的各个方面
name:参数名
value:参数的汉字说明、解释
required:参数是否必须传
paramType:参数放在哪个地方
· header --> 请求参数的获取:@RequestHeader
· query --> 请求参数的获取:@RequestParam
· path(用于restful接口)--> 请求参数的获取:@PathVariable
· body(不常用)
· form(不常用)
dataType:参数类型,默认String,其它值dataType="Integer"
defaultValue:参数的默认值
@ApiResponses:用在请求的方法上,表示一组响应
@ApiResponse:用在@ApiResponses中,一般用于表达一个错误的响应信息
code:数字,例如400
message:信息,例如"请求参数没填好"
response:抛出异常的类
@ApiModel:用于响应类上,表示一个返回响应数据的信息
(这种一般用在post创建的时候,使用@RequestBody这样的场景,
请求参数无法使用@ApiImplicitParam注解进行描述的时候)
@ApiModelProperty:用在属性上,描述响应类的属性
6、整合 Spring Security
// 配置权限豁免,才能正常访问 localhost:8080/swagger-ui.html
.antMatchers("/swagger-ui.html").permitAll()
.antMatchers("/swagger-resources/**").permitAll()
.antMatchers("/webjars/**").permitAll()
.antMatchers("/v2/api-docs").permitAll()
