springboot整合swagger2以及swagger2的介绍与Spring Security的整合使用

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()
