Question

我想将hawt.io作为嵌入式组件添加到具有嵌入式tomcat服务器的spring boot'fulll jar'应用程序中。

我该怎么做？我怎么能部署hawt.io war文件？

更新：我添加了依赖项：

的 hawtio幅
的 hawtio核
的 hawtio-插件-的mbean
的 hawtio-springboot 到我的pom

当我立即启动应用程序并打开网址 localhost：8080 / hatio / index.html 时，我会显示登录页面。由于我不知道用户名和密码我添加了的 hawtio.authenticationEnabled =假 到我的 application.properties

但是 - 现在我收到了警告 'WARN 3420 --- [nio-8080-exec-4] o.s.web.servlet.PageNotFound：请求方法'POST'不受支持' 后跟一个空指针异常。

我有完全相同的问题 - 这就是我如何解决问题。

我发现spring-boot不支持遗留web.xml配置，这是maven-war-plugin在你自己的战争之上覆盖hawtio-web项目时得到的。由此产生的战争包含您的网络代码以及hawtio-web存档的内容。

请参阅http://docs.spring.io/spring-boot/docs/current/reference/html/howto-traditional-deployment.html

所以我开始在spring中配置servlet和过滤器。

首先将必要的依赖项添加到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>

我正在使用这些版本：

<hawtio.version>2.0.0</hawtio.version>
<spring-boot.version>1.2.3.RELEASE</spring-boot.version>

添加Configuration类以配置servlet和过滤器：

@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 jolokiaproxy() {
        return new ServletRegistrationBean(new ProxyServlet(), "/hawtio/proxy/*");
    }

    @Bean
    public ServletRegistrationBean kubeservice() {
        return new ServletRegistrationBean(new ServiceServlet(), "/hawtio/service/*");
    }

    @Bean
    public ServletRegistrationBean kubepod() {
        return new ServletRegistrationBean(new PodServlet(), "/hawtio/pod/*");
    }

    @Bean
    public ServletRegistrationBean fileupload() {
        return new ServletRegistrationBean(new UploadServlet(), "/hawtio/file-upload/*");
    }

    @Bean
    public ServletRegistrationBean loginservlet() {
        return new ServletRegistrationBean(new LoginServlet(), "/hawtio/auth/login/*");
    }

    @Bean
    public ServletRegistrationBean logoutservlet() {
        return new ServletRegistrationBean(new LogoutServlet(), "/hawtio/auth/logout/*");
    }

    @Bean
    public ServletRegistrationBean keycloakservlet() {
        return new ServletRegistrationBean(new KeycloakServlet(), "/hawtio/keycloak/*");
    }

    @Bean
    public ServletRegistrationBean exportcontextservlet() {
        return new ServletRegistrationBean(new ExportContextServlet(), "/hawtio/exportContext/*");
    }

    @Bean
    public ServletRegistrationBean mavenSource() {
        return new ServletRegistrationBean(new JavaDocServlet(), "/hawtio/javadoc/*");
    }

    @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;
    }

}

我用jetty和tomcat测试了这个 - 它适用于两者。我还提交了这个作为hawtio的补丁，但它尚未发布。你可以自己编译hawtio并导入HawtioConfiguration： https://github.com/hawtio/hawtio/blob/master/hawtio-springboot/src/main/java/io/hawt/springboot/HawtioConfiguration.java

我还更新了hawtio-sample以使用HawtioConfiguration： https://github.com/hawtio/hawtio/tree/master/hawtio-sample-springboot

现在我可以访问http://localhost:8080/hawtio/index.html

来访问hawtio

希望这会有所帮助。

祝你好运。

以下是我从最新教程中得到的内容（我猜测Hawtio已经改进了这个问题，因为这个问题最初被问到并回答）：使用spring-boot-starter-parent 1.3.5.RELEASE，Hawtio版本1.4.64 ，包括以下依赖项：

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </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>
        <dependency>
            <groupId>org.jolokia</groupId>
            <artifactId>jolokia-core</artifactId>
        </dependency>
    </dependencies>

以下是一个示例应用程序类，它使用禁用的身份验证设置Hawtio：

@SpringBootApplication
@EnableHawtio
public class SampleApplication {
    @Autowired
    private ServletContext servletContext;

    public static void main(String[] args) {
        System.setProperty(AuthenticationFilter.HAWTIO_AUTHENTICATION_ENABLED, "false");
        SpringApplication.run(SampleApplication.class, args);
    }

    @PostConstruct
    public void init() {
        final ConfigManager configManager = new ConfigManager();
        configManager.init();
        servletContext.setAttribute("ConfigManager", configManager);
    }

    /**
     * Set things up to be in offline mode
     * @return
     * @throws Exception
     */
    @Bean
    public ConfigFacade configFacade() throws Exception {
        ConfigFacade config = new ConfigFacade() {
            public boolean isOffline() {
                return true;
            }
        };
        config.init();
        return config;
    }
}
