Springboot版本 2.1.14.RELEASE
Swagger版本 2.9.2
1. 引入jar pom.xml中加入
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.9.2</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.9.2</version>
</dependency>
2. 加入配置
public class WebConfiguration implements WebMvcConfigurer {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/**").addResourceLocations(
"classpath:/static/");
registry.addResourceHandler("/swagger-ui.html").addResourceLocations(
"classpath:/META-INF/resources/");
registry.addResourceHandler("/webjars/**").addResourceLocations(
"classpath:/META-INF/resources/webjars/");
}
}
3. 如果发现配置了之后仍然无法访问,可以跟踪下源代码 找到正确答案
通过 addResourceHandlers找到父类 org.springframework.web.servlet.config.annotation.DelegatingWebMvcConfiguration#addResourceHandlers
再向上一级 org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport#resourceHandlerMapping
@Bean
@Nullable
public HandlerMapping resourceHandlerMapping() {
Assert.state(this.applicationContext != null, "No ApplicationContext set");
Assert.state(this.servletContext != null, "No ServletContext set");
ResourceHandlerRegistry registry = new ResourceHandlerRegistry(this.applicationContext,
this.servletContext, mvcContentNegotiationManager(), mvcUrlPathHelper());
**addResourceHandlers(registry);**
AbstractHandlerMapping handlerMapping = registry.getHandlerMapping();
if (handlerMapping == null) {
return null;
}
handlerMapping.setPathMatcher(mvcPathMatcher());
handlerMapping.setUrlPathHelper(mvcUrlPathHelper());
handlerMapping.setInterceptors(getInterceptors());
handlerMapping.setCorsConfigurations(getCorsConfigurations());
return handlerMapping;
}
关键一行代码 addResourceHandlers(registry);
WebMvcConfigurationSupport 有一个空的实现方法
/**
* Override this method to add resource handlers for serving static resources.
* @see ResourceHandlerRegistry
*/
protected void addResourceHandlers(ResourceHandlerRegistry registry) {
}
有人提示 重写该方法,我试了下没有作用。
别人的答案永远只是必然的答案
不过你可以试试,对不对全看运气。
跟踪源码找答案,进步中。。。
