SpringBoot整合Swagger3.0

引入pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <maven.compiler.target>11</maven.compiler.target>
    </properties>

</project>

在启动类加上@EnableOpi注解

package com.young;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import springfox.documentation.oas.annotations.EnableOpenApi;

@SpringBootApplication
@EnableOpenApi
public class Swagger03Application {
    public static void main(String[] args) {
        SpringApplication.run(Swagger03Application.class,args);
    }
}

Swagger3和Swagger2的注解对比
在这里插入图片描述

在dto类里面，使用schema来描述类的信息和类的属性

package com.young.entity;

import io.swagger.v3.oas.annotations.media.Schema;
import lombok.Data;

@Data
@Schema(description = "用户类")
public class User {
    @Schema(description = "用户id")
    private String id;
    @Schema(description = "用户姓名")
    private String name;
    @Schema(description = "用户年龄")
    private String age;
}

controller层，用@Tag注解描述这个controller类的具体功能，然后@Operation注解描述某个方法的具体功能，@Parameters用来记录方法中需要的参数，每个参数的含义。

package com.young.controller;

import com.young.entity.User;
import io.swagger.v3.oas.annotations.Operation;
import io.swagger.v3.oas.annotations.Parameter;
import io.swagger.v3.oas.annotations.Parameters;
import io.swagger.v3.oas.annotations.tags.Tag;
import org.springframework.web.bind.annotation.*;

@RestController
@RequestMapping("/user")
@Tag(name = "用户管理")
public class UserController {
    @Operation(summary = "根据用户id获取用户",tags = "用户管理")
    @Parameters({
            @Parameter(name = "id",description = "用户id")
    })
    @GetMapping("/{id}")
    public User getUserById(@PathVariable("id")String id){
        User user=new User();
        user.setId(id);
        user.setName("hello");
        user.setAge("0");
        return user;
    }
}

Swagger3的配置类

package com.young.config;

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;

@Configuration
public class Swagger03Config {
    @Bean
    public Docket createDocket(){
        return new Docket(DocumentationType.OAS_30)
                .enable(true) //是否开启OpenApi
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.young.controller")) //指定要扫描的包
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo(){
        return new ApiInfoBuilder()
                .title("未来先遣者")
                .contact(new Contact("沉河不浮",
                        "https://blog.csdn.net/weixin_55850954",
                        "2827523200@qq.com"))
                .description("记录SpringBoot整合Swagger3")
                .license("Apache2.0")
                .licenseUrl("https://localhost:apache")
                .build();
    }
}

application.yml

spring:
  mvc:
    pathmatch:
      matching-strategy: ant_path_matcher #这里一定要设置，因为swagger-ui默认使用的是ant_path_matcher
springfox:
  documentation:
    swagger-ui:
      enabled: true
      base-url: /documentation #这里可以设置访问的路径

启动项目，访问http://localhost:8080/documentation/swagger-ui/index.html

SpringBoot整合Swagger和SpringSecurity

在pom.xml里添加springSecurity的依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>

重启项目，然后重新访问接口文档，发现被拦截了
在这里插入图片描述
我们配置Security的配置类，来解除对接口文档访问的拦截

package com.young.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http)throws Exception{
        http.authorizeRequests().antMatchers("/static/**",
                "/swagger-resources/**",
                "/documentation/**", //因为刚才在application.yml里面设置baseUrl为documentation，所以要加上这个
                "/v2/**",
                "/v3/**",
                "/swagger-ui/**",
                "**/upload/**",
                "/index.jsp").permitAll()
                .anyRequest().authenticated();
    }
}
