I had exactly the same issue - and here is how I solved the problem.
I found out that spring-boot doesnt support legacy web.xml configuration which is what you get when the maven-war-plugin does the overlay of the hawtio-web project on top of your own war.
The resulting war contains both your web code as well as the content of the hawtio-web archive.
See http://docs.spring.io/spring-boot/docs/current/reference/html/howto-traditional-deployment.html
So I started the process of configuring the servlets and filters in spring.
First add the necesary dependencies to pom.xml
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>${spring-boot-version}</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-actuator</artifactId>
<version>${spring-boot-version}</version>
</dependency>
<dependency>
<groupId>io.hawt</groupId>
<artifactId>hawtio-springboot</artifactId>
<version>${hawtio.version}</version>
</dependency>
<dependency>
<groupId>io.hawt</groupId>
<artifactId>hawtio-core</artifactId>
<version>${hawtio.version}</version>
</dependency>
</dependencies>
Im using these versions:
<hawtio.version>2.0.0</hawtio.version>
<spring-boot.version>1.2.3.RELEASE</spring-boot.version>
Add a Configuration class to configure the servlets and filters:
@Configuration
public class HawtioConfiguration extends WebMvcConfigurerAdapter {
@Override
public void addResourceHandlers(final ResourceHandlerRegistry registry) {
registry.addResourceHandler("/hawtio/plugins/**").addResourceLocations("/app/", "classpath:/static/hawtio/app/");
registry.addResourceHandler("/hawtio/**").addResourceLocations("/", "/app/", "classpath:/static/hawtio/",
"classpath:/static/hawtio/app/");
}
@Override
public void addViewControllers(final ViewControllerRegistry registry) {
registry.addViewController("/hawtio/plugin").setViewName("forward:/plugin");
registry.addViewController("/hawtio/").setViewName("redirect:/hawtio/index.html");
}
@Bean
public ServletRegistrationBean userServlet() {
return new ServletRegistrationBean(new UserServlet(), "/user/*", "/hawtio/user/*");

}

}
@Bean
public ServletRegistrationBean contextFormatter() {
return new ServletRegistrationBean(new ContextFormatterServlet(), "/hawtio/contextFormatter/*");
}
@Bean
public ServletRegistrationBean gitServlet() {
return new ServletRegistrationBean(new GitServlet(), "/hawtio/git/*");
}
@Bean
public ServletListenerRegistrationBean hawtioContextListener() {
return new ServletListenerRegistrationBean<>(new HawtioContextListener());
}
@Bean
public ServletListenerRegistrationBean fileCleanerCleanup() {
return new ServletListenerRegistrationBean<>(new FileCleanerCleanup());
}
@Bean
public FilterRegistrationBean redirectFilter() {
final FilterRegistrationBean filter = new FilterRegistrationBean();
filter.setFilter(new RedirectFilter());
filter.setUrlPatterns(Collections.singletonList("/hawtio/*"));
return filter;
}
@Bean
public FilterRegistrationBean sessionExpiryFilter() {
final FilterRegistrationBean filter = new FilterRegistrationBean();
filter.setFilter(new SessionExpiryFilter());
filter.setUrlPatterns(Collections.singletonList("/hawtio/*"));
return filter;
}
@Bean
public FilterRegistrationBean cacheFilter() {
final FilterRegistrationBean filter = new FilterRegistrationBean();
filter.setFilter(new CacheHeadersFilter());
filter.setUrlPatterns(Collections.singletonList("/hawtio/*"));
return filter;
}
@Bean
public FilterRegistrationBean CORSFilter() {
final FilterRegistrationBean filter = new FilterRegistrationBean();
filter.setFilter(new CORSFilter());
filter.setUrlPatterns(Collections.singletonList("/hawtio/*"));
return filter;
}
@Bean
public FilterRegistrationBean XFrameOptionsFilter() {
final FilterRegistrationBean filter = new FilterRegistrationBean();
filter.setFilter(new XFrameOptionsFilter());
filter.setUrlPatterns(Collections.singletonList("/hawtio/*"));
return filter;
}
@Bean
public FilterRegistrationBean AuthenticationFilter() {
final FilterRegistrationBean filter = new FilterRegistrationBean();
filter.setFilter(new AuthenticationFilter());
filter.setUrlPatterns(Arrays.asList("/hawtio/auth/*", "/jolokia/*", "/hawtio/upload/*", "/hawtio/javadoc/*"));
return filter;
}
}
I have tested this with both jetty and tomcat - and it works with both.
I have also submitted this as a patch to hawtio, but it is not released as of yet. You could compile hawtio yourself and import the HawtioConfiguration:
https://github.com/hawtio/hawtio/blob/master/hawtio-springboot/src/main/java/io/hawt/springboot/HawtioConfiguration.java
I have also updated the hawtio-sample to use the HawtioConfiguration:
https://github.com/hawtio/hawtio/tree/master/hawtio-sample-springboot
Now i can access hawtio by visiting http://localhost:8080/hawtio/index.html
Hope this helps.
Good luck.
