SpringBoot项目配置Swagger

1、Swagger简介

根据在代码中使用自定义的注解来生成接口文档，这样做的好处是 在开发接口时可以通过swagger 将接口文档定义好提供给前端查询具体参数信息，同时也方便以后的维护。

当前项目配置好以后的Swagger原型：

2、Boot整合Swagger案例(复制可直接使用)

2.1、Pom文件依赖配置

            </plugin>
        </plugins>
    </build>

</project>

2.2、application.properties配置信息

#设置端口号
server.port=8088

#swagger配置
spring.mvc.pathmatch.matching-strategy=ant_path_matcher

2.3、在启动类同级别创建Config包

2.4、Swagger配置信息

2.4.1、配置跨域

package com.example.bootswagger.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;

@Configuration
public class GlobalCorsConfig {

    /**
     * 跨域处理
     */
    @Bean
    public CorsFilter corsFilter() {
        CorsConfiguration config = new CorsConfiguration();
        config.setAllowCredentials(true);
        // 设置访问源地址
        config.addAllowedOriginPattern("*");
        // 设置访问源请求头
        config.addAllowedHeader("*");
        // 设置访问源请求方法
        config.addAllowedMethod("*");
        // 有效期 1800秒
        config.setMaxAge(1800L);

        // 添加映射路径，拦截一切请求
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", config);

        // 返回新的CorsFilter
        return new CorsFilter(source);
    }
}

2.4.2、Swagger自定义配置

package com.example.bootswagger.config;

import lombok.Builder;
import lombok.Data;

/**
 * Swagger自定义配置
 */
@Data
@Builder
public class SwaggerProperties {

    /**
     * API文档生成基础路径
     */
    private String apiBasePackage;

    /**
     * 是否要启用登录认证
     */
    private boolean enableSecurity;

    /**
     * 文档标题
     */
    private String title;
    /**
     * 文档描述
     */
    private String description;
    /**
     * 文档版本
     */
    private String version;
    /**
     * 文档联系人姓名
     */
    private String contactName;
    /**
     * 文档联系人网址
     */
    private String contactUrl;
    /**
     * 文档联系人邮箱
     */
    private String contactEmail;
}

2.4.3、Swagger API文档相关配置(Swagger名称,控制层包扫描)

注意.apiBasePackage(“com.example.bootswagger.controller”)是用来设置你的Controller所在包路径!

package com.example.bootswagger.config;

import com.github.xiaoymin.knife4j.spring.annotations.EnableKnife4j;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import springfox.bean.validators.configuration.BeanValidatorPluginsConfiguration;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

/**
 * Swagger API文档相关配置
 *
 * @author mac
 */
@Configuration
@EnableSwagger2
@EnableKnife4j
@Import(BeanValidatorPluginsConfiguration.class)
public class SwaggerConfig extends SuperSwaggerConfig {


    @Override
    public SwaggerProperties swaggerProperties() {
        return SwaggerProperties.builder()
        		//设置Swagger扫描的Controller路径，只有扫描到了才会生成接口文档
                .apiBasePackage("com.example.bootswagger.controller")
                .title("swagger测试")
                .description("后台接口文档")
                .contactName("wranglings")
                .version("1.0")
                .enableSecurity(true)
                .build();
    }

}

2.4.4、Swagger基础配置

package com.example.bootswagger.config;

import org.springframework.context.annotation.Bean;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.*;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spi.service.contexts.SecurityContext;
import springfox.documentation.spring.web.plugins.Docket;

import java.util.Collections;
import java.util.List;

/**
 * Swagger基础配置
 * @author mac
 */
public abstract class SuperSwaggerConfig {

    /**
     * 自定义Swagger配置
     */
    public abstract SwaggerProperties swaggerProperties();

    @Bean
    public Docket docket() {
        SwaggerProperties swaggerProperties = swaggerProperties();
        Docket docket = new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo(swaggerProperties))
                .select()
                .apis(RequestHandlerSelectors.basePackage(swaggerProperties.getApiBasePackage()))
                .paths(PathSelectors.any())
                .build();

        if (swaggerProperties.isEnableSecurity()) {
            docket.securitySchemes(Collections.singletonList(securitySchemes()))
                    .securityContexts(Collections.singletonList(securityContexts()));
        }
        return docket;
    }

    private ApiInfo apiInfo(SwaggerProperties swaggerProperties) {
        return new ApiInfoBuilder()
                .title(swaggerProperties.getTitle() + " 服务API接口文档")
                .description(swaggerProperties.getDescription())
                .version(swaggerProperties.getVersion())
                .contact(new Contact(swaggerProperties.getContactName(), swaggerProperties.getContactUrl(), swaggerProperties.getContactEmail()))
                .version(swaggerProperties.getVersion())
                .build();
    }

    private ApiKey securitySchemes() {
        //设置请求头信息
        return new ApiKey("token", "accessToken", "header");
    }


    private SecurityContext securityContexts() {
        return SecurityContext.builder()
                .securityReferences(defaultAuth())
                .operationSelector(operationContext -> true)
                .build();
    }

    private List<SecurityReference> defaultAuth() {
        AuthorizationScope authorizationScope = new AuthorizationScope("xxx", "描述信息");
        AuthorizationScope[] authorizationScopes = new AuthorizationScope[1];
        authorizationScopes[0] = authorizationScope;
        return Collections.singletonList(new SecurityReference("Authorization", authorizationScopes));
    }

}

2.4.5、创建测试VO 和 Controller

创建用户Vo

package com.example.bootswagger.pojo.vo;

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

import java.io.Serializable;

@Data
@AllArgsConstructor
@NoArgsConstructor
@ApiModel("用户vo")
public class UserVo implements Serializable {

    @ApiModelProperty(value = "用户id")
    private Integer userId;

    @ApiModelProperty(value = "用户名称")
    private String userName;

    @ApiModelProperty(value = "用户密码")
    private String password;

}

创建Controller层

package com.example.bootswagger.controller;

import com.example.bootswagger.pojo.vo.UserVo;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.apache.commons.lang3.ObjectUtils;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@Api(tags = "用户信息")
@RestController
@RequestMapping("/user")
public class UserController {

    @ApiOperation(value = "查询用户详细信息")
    @GetMapping("/getInfo")
    public UserVo getInfo(Integer userId){
        UserVo userVo = new UserVo();
        if(ObjectUtils.isNotEmpty(userId)){
            userVo.setUserId(userId);
            userVo.setUserName("admin");
            userVo.setPassword("root");
        }
        return userVo;
    }

}

2.4.6、启动Swagger，重点菜单说明

链接: http://localhost:8088/doc.html
主页

授权

文档管理
这里可以配置一些消息头和一些查询参数，可以添加多个

剩下的菜单就是读取的Controller的信息
这里是测试案例中配置的用户信息接口

3、Swagger常用注解说明

3.1、@ApiModel(“用户vo”)

@ApiModel注解，用来配置Swagger文档中返回的对象名称，常用在实体类中;
如下图：

3.2、@ApiModelProperty(value = “用户id”)

@ApiModelProperty，用来配置Swagger文档中返回的对象的属性名称，如上图！
用户id、用户名称这些都是通过该注解配置的。

3.3、@Api(tags = “用户信息”)

@Api(tags = “”),用来配置控制层，在Swagger文档的菜单项可以体现！如下图

3.4、@ApiOperation(value = “查询用户详细信息”)

@ApiOperation(value = “”),用来配置控制层中具体的方法，在Swagger文档的菜单项可以体现！如上图文章来源地址https://www.toymoban.com/news/detail-419066.html
