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<Object> {
@Override
public boolean supports(MethodParameter returnType, Class<? extends HttpMessageConverter<?>> converterType) {
return true;
}
@Override
public Object beforeBodyWrite(Object object, MethodParameter returnType, MediaType selectedContentType, Class<? extends HttpMessageConverter<?>> selectedConverterType, ServerHttpRequest request, ServerHttpResponse response) {
if (object instanceof ResponseData) {
return object;
}
return ResponseData.of().setData(object);
}
}
请求报错
而且后台还说找不到映射路径
