org.atmosphere.cpr.AtmosphereMappingException 在 Spring 引导可执行文件 war 文件中
org.atmosphere.cpr.AtmosphereMappingException in Spring Boot executable war file
我有一个 Spring 引导应用程序，我在其中集成了 Atmosphere Framework.
这是 Application.java 文件：
package com.myproject.something;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.core.env.SimpleCommandLinePropertySource;
@SpringBootApplication
public class Application extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
public static void main(String[] args) {
SpringApplication app = new SpringApplication(Application.class);
addDefaultProfile(app, new SimpleCommandLinePropertySource(args));
app.run(args);
}
private static void addDefaultProfile(SpringApplication app, SimpleCommandLinePropertySource source) {
if (!source.containsProperty("spring.profiles.active")
&& !System.getenv().containsKey("SPRING_PROFILES_ACTIVE")) {
app.setAdditionalProfiles("dev");
}
}
}
为了将 Atmosphere Framework 集成 到我的 Spring 引导应用程序中，我一直在松散地关注 this resource combining elements from the official Atmosphere Documentation。
我最终得到了 类 MyAtmosphereConfig.java 和 MyAtmosphereManagedService.java:
package com.myproject.something.atmosphere;
import java.util.Collections;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import org.atmosphere.cpr.AtmosphereServlet;

registration.setOrder(Ordered.HIGHEST_PRECEDENCE);
return registration;
}
private static class EmbeddedAtmosphereInitializer extends ContainerInitializer

}
}
}

}
@Disconnect
public void onDisconnect() {
String atmosJSessionId = resource.getRequest().getRequestedSessionId();
log.info("Unregistering Atmosphere client connection with jsession = " + atmosJSessionId);
}
}
我一直在 Eclipse IDE 中开发，将我的 Spring 引导应用程序作为 Java 应用程序执行。 (右键单击 Application.java -> 运行 As -> Java Application)
运行按照上述方式将其设置为来自 Eclipse IDE 的 Java 应用程序- 前面-我的应用程序的结束部分可以 成功访问 Atmosphere Framework 公开的 URL ，如下所示：
(function() {
'use strict';
setTimeout(function() {
// Setup Atmosphere client
var myAtmosphereUrl = 'http://localhost:8080/myAtmosphereUrl';
var socket = atmosphere;
var subSocket;
var transport = 'sse';
var request = {
url : myAtmosphereUrl,
contentType : "application/json",
logLevel : 'debug',
transport : transport,
trackMessageLength : true,
reconnectInterval : 5000
};
request.onOpen = function(response) {
transport = response.transport;
request.uuid = response.request.uuid;
console.log("onOpen called!");
};
request.onMessage = function(response) {
transport = response.transport;
request.uuid = response.request.uuid;
console.log("onMessage called!");
};
subSocket = socket.subscribe(request);
}, 1000);
})();
在 浏览器控制台 的前端，我看到 HTTP 200 状态代码，在 Eclipse IDE 的后端] 控制台 ，它给我日志消息 Initiating Atmosphere client connection with jsession = A4A8790C27D531FE7B2CD82B5B9C9447。
不幸的是，在打包我的项目到可执行war文件并将其作为服务部署在Debian服务器上之后，它不再工作了，在后端的日志中留下一条错误消息：

我已经尝试将 atmosphere.xml 文件放入 war 文件 的 WEB-INF 文件夹中，但似乎仍然未拾取带有 @ManagedService 注释的 Servlet。
这是atmosphere.xml的内容，没有解决错误：
<atmosphere-handlers>
<atmosphere-handler support-session="true"
context-root="/"
broadcaster="org.atmosphere.cpr.DefaultBroadcaster"
class-name="com.myproject.something.atmosphere.MyAtmosphereManagedService">
</atmosphere-handler>
</atmosphere-handlers>
谁能告诉我我的配置有什么问题，或者这可能是与嵌入式 Tomcat、Atmosphere 和 Spring Boot 的次要版本相关的错误？
编辑：
可以通过克隆 official Atmosphere-Spring-Boot Sample project 并更改 pom.xml 将项目打包到 war 文件来重现此错误：

我找到了两个修复程序。
第一次修复：
1. 将 pom.xml 中的 Spring 引导版本更改为：
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.7.RELEASE</version>
</parent>
2。完成！
第二次修复：（如果不能更改版本）
- 将您的项目打包成一个
jar文件，然后@ManagedServices被识别。
注意：您可能需要在打包前将静态文件（js和html）复制到您的pom.xml中。
如果您正在使用 Spring boot 2 然后使用下面的配置测试。
@Bean
public ServletRegistrationBean < HttpServlet > PushServlet() {
ServletRegistrationBean pushServlet = new ServletRegistrationBean(new org.primefaces.push.PushServlet(), "/primepush/*");
pushServlet.addInitParameter("org.atmosphere.annotation.packages", "org.primefaces.push");
pushServlet.addInitParameter("org.atmosphere.cpr.packages", "com.ik");
pushServlet.setAsyncSupported(true);
pushServlet.setLoadOnStartup(0);
pushServlet.setOrder(Ordered.HIGHEST_PRECEDENCE);
return pushServlet;
}
com.ik是你的工程包名，就是scan
我有一个 Spring 引导应用程序，我在其中集成了 Atmosphere Framework.
这是 Application.java 文件：
package com.myproject.something;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.core.env.SimpleCommandLinePropertySource;
@SpringBootApplication
public class Application extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
public static void main(String[] args) {
SpringApplication app = new SpringApplication(Application.class);
addDefaultProfile(app, new SimpleCommandLinePropertySource(args));
app.run(args);
}
private static void addDefaultProfile(SpringApplication app, SimpleCommandLinePropertySource source) {
if (!source.containsProperty("spring.profiles.active")
&& !System.getenv().containsKey("SPRING_PROFILES_ACTIVE")) {
app.setAdditionalProfiles("dev");
}
}
}
为了将 Atmosphere Framework 集成 到我的 Spring 引导应用程序中，我一直在松散地关注 this resource combining elements from the official Atmosphere Documentation。

可执行文件war的创建由Maven命令maven package触发，并以这种方式在pom.xml中配置:

我已经尝试将 atmosphere.xml 文件放入 war 文件 的 WEB-INF 文件夹中，但似乎仍然未拾取带有 @ManagedService 注释的 Servlet。
这是atmosphere.xml的内容，没有解决错误：
<atmosphere-handlers>
<atmosphere-handler support-session="true"
context-root="/"
broadcaster="org.atmosphere.cpr.DefaultBroadcaster"
class-name="com.myproject.something.atmosphere.MyAtmosphereManagedService">
</atmosphere-handler>
</atmosphere-handlers>
谁能告诉我我的配置有什么问题，或者这可能是与嵌入式 Tomcat、Atmosphere 和 Spring Boot 的次要版本相关的错误？
编辑：
可以通过克隆 official Atmosphere-Spring-Boot Sample project 并更改 pom.xml 将项目打包到 war 文件来重现此错误：

我找到了两个修复程序。
第一次修复：
1. 将 pom.xml 中的 Spring 引导版本更改为：
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.7.RELEASE</version>
</parent>
2。完成！
第二次修复：（如果不能更改版本）
- 将您的项目打包成一个
jar文件，然后@ManagedServices被识别。
注意：您可能需要在打包前将静态文件（js和html）复制到您的pom.xml中。
如果您正在使用 Spring boot 2 然后使用下面的配置测试。
@Bean
public ServletRegistrationBean < HttpServlet > PushServlet() {
ServletRegistrationBean pushServlet = new ServletRegistrationBean(new org.primefaces.push.PushServlet(), "/primepush/*");
pushServlet.addInitParameter("org.atmosphere.annotation.packages", "org.primefaces.push");
pushServlet.addInitParameter("org.atmosphere.cpr.packages", "com.ik");
pushServlet.setAsyncSupported(true);
pushServlet.setLoadOnStartup(0);
pushServlet.setOrder(Ordered.HIGHEST_PRECEDENCE);
return pushServlet;
}
com.ik是你的工程包名，就是scan
