这篇文章给大家介绍Springboot2中怎么对knife4j进行整合,内容非常详细,感兴趣的小伙伴们可以参考借鉴,希望对大家能有所帮助。
在网站设计制作、网站设计过程中,需要针对客户的行业特点、产品特性、目标受众和市场情况进行定位分析,以确定网站的风格、色彩、版式、交互等方面的设计方向。创新互联还需要根据客户的需求进行功能模块的开发和设计,包括内容管理、前台展示、用户权限管理、数据统计和安全保护等功能。
1.代码结构

2.pom.xml
4.0.0 org.springframework.boot spring-boot-starter-parent 2.2.5.RELEASE com.example knife4j-demo 0.0.1-SNAPSHOT knife4j-demo Demo project for Spring Boot 1.8 org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-test test org.junit.vintage junit-vintage-engine com.github.xiaoymin knife4j-spring-boot-starter 2.0.2 com.alibaba fastjson 1.2.58 org.projectlombok lombok 1.18.10 org.springframework.boot spring-boot-maven-plugin
3.配置类
package com.example.knife4j.demo.config;
import com.github.xiaoymin.knife4j.spring.annotations.EnableKnife4j;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import springfox.bean.validators.configuration.BeanValidatorPluginsConfiguration;
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;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
@Configuration
@EnableSwagger2
@EnableKnife4j
@Import(BeanValidatorPluginsConfiguration.class)
public class SwaggerConfiguration {
@Bean(value = "defaultApi2")
public Docket defaultApi2() {
Docket docket=new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
//分组名称
.groupName("2.X版本")
.select()
//这里指定Controller扫描包路径(项目路径也行)
.apis(RequestHandlerSelectors.basePackage("com.example.knife4j.demo"))
.paths(PathSelectors.any())
.build();
return docket;
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("不重要")
.description("测试名称不重要")
.termsOfServiceUrl("http://localhost:88888/")
.contact("10086@mail.com")
.version("1.0")
.build();
}
}4.模型bean
package com.example.knife4j.demo.beans;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
/**
* 创建时间: 23:09 2018/9/19
* 修改时间:
* 编码人员: ZhengQf
* 版 本: 0.0.1
* 功能描述:
*/
@ApiModel(value = "用户模型")
public class UserEntity {
@ApiModelProperty(value="id" ,required= true,example = "123")
private Integer id;
@ApiModelProperty(value="用户姓名" ,required=true,example = "郑钦锋")
private String name;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Override
public String toString() {
return "DemoDoctor [id=" + id + ", name=" + name + "]";
}
}5.两个接口controller
package com.example.knife4j.demo.controller;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@Api(value = "IndexController测试接口")
@RestController
public class IndexController {
@ApiOperation(value = "测试index接口", nickname = "测试IndexController的index接口")
@GetMapping("/index")
public String index() {
return "测试IndexController的index接口...";
}
}package com.example.knife4j.demo.controller;
import com.example.knife4j.demo.beans.UserEntity;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.*;
@Api(value = "用户接口")
@RestController
public class UserController {
@ApiOperation(value = "获取用户信息接口", nickname = "根据用户ID获取用户相关信息")
@ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "int")
@PostMapping("/postMember")
public UserEntity postMember(@RequestParam Integer id) {
UserEntity userEntity = new UserEntity();
userEntity.setId(id);
userEntity.setName("admin");
return userEntity;
}
@ApiOperation(value = "添加用户", nickname = "添加用户接口1", notes = "入参是复杂对象", produces = "application/json")
@PostMapping("/postUser")
@ResponseBody
@ApiImplicitParam(paramType = "query", name = "userId", value = "用户id", required = true, dataType = "int")
public UserEntity postUser(@RequestBody UserEntity user, @RequestParam("userId") int userId) { // 这里用包装类竟然报错
if (user.getId() == userId) {
return user;
}
return new UserEntity();
}
@ApiOperation(value = "添加用户", nickname = "添加用户接口2", notes = "入参是简单对象", produces = "application/json")
@PostMapping("/addUser")
@ResponseBody
@ApiImplicitParams({
@ApiImplicitParam(paramType = "query", name = "userName", value = "用户姓名", required = true, dataType = "String"),
@ApiImplicitParam(paramType = "query", name = "id", value = "用户id", required = true, dataType = "int")})
public UserEntity addUser(String userName, int id) {
UserEntity userEntity = new UserEntity();
userEntity.setName(userName);
userEntity.setId(id);
return userEntity;
}
}6.srpingboot项目启动类
package com.example.knife4j.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import springfox.documentation.spring.web.SpringfoxWebMvcConfiguration;
@ConditionalOnClass(SpringfoxWebMvcConfiguration.class)
@SpringBootApplication
public class Knife4jDemoApplication implements WebMvcConfigurer {
public static void main(String[] args) {
SpringApplication.run(Knife4jDemoApplication.class, args);
}
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("doc.html").addResourceLocations("classpath:/META-INF/resources/");
registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
}
}这样简单一配置,就ok了,浏览器访问:http://127.0.0.1:8080/doc.html

不过,在项目中我使用了ResponseBodyAdvice接口对项目接口响应内容做统一处理,然后使用knife4j就出问题了。
ResponseBodyAdvice接口实现如下:
import org.springframework.context.annotation.Configuration; import org.springframework.core.MethodParameter; import org.springframework.http.MediaType; import org.springframework.http.converter.HttpMessageConverter; import org.springframework.http.server.ServerHttpRequest; import org.springframework.http.server.ServerHttpResponse; import org.springframework.web.bind.annotation.RestControllerAdvice; import org.springframework.web.servlet.config.annotation.EnableWebMvc; import org.springframework.web.servlet.mvc.method.annotation.ResponseBodyAdvice; /** * 自定义advise ,对restful请求响应体进行统一规范 */ @EnableWebMvc @Configuration @RestControllerAdvice public class ResponseAdvise implements ResponseBodyAdvice
请求报错

而且后台还说找不到映射路径
2020-03-10 23:31:01.533 WARN 7940 --- [nio-8080-exec-1] o.s.web.servlet.PageNotFound : No mapping for GET /service-worker.js
2020-03-10 23:31:01.560 WARN 7940 --- [nio-8080-exec-4] o.s.web.servlet.PageNotFound : No mapping for GET /favicon.ico
2020-03-10 23:31:14.468 WARN 7940 --- [nio-8080-exec-8] o.s.web.servlet.PageNotFound : No mapping for GET /service-worker.js
然后,我在ResponseAdvise#beforeBodyWrite方法中打上断点,发现我将swagger的请求内容进行了修改,以至于报了404。
最后在ResponseAdvise类上声明只对本项目的响应体内容进行统一处理
@RestControllerAdvice(basePackages = "com.example.knife4j.demo")
