swagger ui.html 错误,spring boot admin导致swagger-ui.html无法访问的解决办法

spring boot admin版本：2.1.3

swagger2版本：2.7.0

spring boot security版本：2.1.3

问题现象是：spring boot admin可以正常监控了，但是swagger-ui.html却无法打开：

尝试1：重写public void configure(WebSecurity web)

@Override

public void configure(WebSecurity web) {

//allow Swagger URL to be accessed without authentication

web.ignoring().antMatchers("/v2/api-docs",

"/swagger-resources/configuration/ui",

"/swagger-resources",

"/swagger-resources/configuration/security",

"/swagger-ui.html");

}

没有用。

尝试2：更换spring boot admin到2.1.4

仍旧不起作用。

最终解决办法：

1.重写连接器的addResourceHandlers方法：

registry.addResourceHandler("/templates/**.js").addResourceLocations("classpath:/templates/");

registry.addResourceHandler("/templates/**.css").addResourceLocations("classpath:/templates/");

registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/");

registry.addResourceHandler("swagger-ui.html")

.addResourceLocations("classpath:/META-INF/resources/");

registry.addResourceHandler("/webjars/**")

.addResourceLocations("classpath:/META-INF/resources/webjars/");

2.在安全配置里加入：

http.authorizeRequests().antMatchers("/v2/api-docs", "/configuration/ui", "/swagger-resources", "/configuration/security", "/swagger-ui.html", "/webjars/**","/swagger-resources/configuration/ui").permitAll();

重启即可。

如果报错：

java.lang.IllegalStateException: Calling [asyncError()] is not valid for a request with Async state [MUST_DISPATCH]

可以不用管，不影响使用。
