SpringBoot集成knife4j

https://doc.xiaominfo.com/

1.添加pom文件

<!--knife4j 依赖 3.0.2版本会报错,springboot 2.3.4.RELEASE-->
<dependency>
    <groupId>com.github.xiaoymin</groupId>
    <artifactId>knife4j-spring-boot-starter</artifactId>
    <version>3.0.3</version>
</dependency>
<!--swagger 依赖-->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-boot-starter</artifactId>
    <version>3.0.0</version>
</dependency>

Knife4j里面集成了swagger的jar包，所以项目中有一个knife4j的jar包就能使用

2.添加配置文件

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
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.ApiSelectorBuilder;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

/**
 * @Author nitric oxide
 * @Description
 * @Date 6:13 下午 2021/11/11
 */
@EnableSwagger2
@Configuration
public class SwaggerConfig {
    @Bean(value = "defaultApi2")
    public Docket defaultApi2() {
        ApiSelectorBuilder builder = new Docket(DocumentationType.SWAGGER_2)
                .enableUrlTemplating(false)
                .apiInfo(apiInfo())
                // 选择那些路径和api会生成document
                .select()
                // 对所有api进行监控
                .apis(RequestHandlerSelectors.any())
                //这里可以自定义过滤
　　　　　　　　　//.paths(PathSelectors.any())
                .paths(this::filterPath);

        return builder.build();
    }

    private boolean filterPath(String path) {
        boolean ret = path.endsWith("/error");
        if (ret) {
            return false;
        }
        //这块可以写其他的过滤逻辑
        return true;
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("title")
                .description("description")
                .termsOfServiceUrl("https://www.baidu.com")
                .version("1.0")
                .contact(new Contact("nitric oxide", "www.baidu.com", "123@qq.com"))
                .build();
    }
}
