springboot版本号:2.7.3
knife4j:3.0.2
使用步骤
导入 knife4j 的maven坐标
在pom.xml中添加依赖
<dependency> <groupId>com.github.xiaoymin</groupId> <artifactId>knife4j-spring-boot-starter</artifactId> <version>3.0.2</version> </dependency>
在配置类中加入 knife4j 相关配置WebMvcConfiguration.java
/**
* 通过knife4j生成接口文档
* @return
*/
@Bean
public Docket docket() {
ApiInfo apiInfo = new ApiInfoBuilder()
.title("项目接口文档")
.version("2.0")
.description("项目接口文档")
.build();
Docket docket = new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo)
.select()
.apis(RequestHandlerSelectors.basePackage("com.sky.controller"))
.paths(PathSelectors.any())
.build();
return docket;
}
3.
设置静态资源映射,否则接口文档页面无法访问
WebMvcConfiguration.java
/**
* 设置静态资源映射
* @param registry
*/
protected void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/doc.html").addResourceLocations("classpath:/META-INF/resources/");
registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
}
4.访问:localhost:8080/doc.html
完整代码如下:
package com.qing.springboot.config;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
/**
* 配置类,注册web层相关组件
*/
@Configuration
@Slf4j
public class WebMvcConfiguration extends WebMvcConfigurationSupport {
/**
* 通过knife4j生成接口文档
* @return
*/
@Bean
public Docket docket() {
ApiInfo apiInfo = new ApiInfoBuilder()
.title("项目接口文档")
.version("2.0")
.description("项目接口文档")
.build();
Docket docket = new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo)
.select()
.apis(RequestHandlerSelectors.basePackage("com.qing.springboot.controller"))
.paths(PathSelectors.any())
.build();
return docket;
}
/**
* 设置静态资源映射
* @param registry
*/
@Override
protected void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/doc.html").addResourceLocations("classpath:/META-INF/resources/");
registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
}
}
友情提示:有些内容是可以根据自己的项目进行改写的,次框架还有一些其他的功能,请自行学习。祝每次运行顺利!
