SpringBoot：WebSocket使用Service层的方法

方法一：

创建工具类 ApplicationContextRegister.java

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.context.annotation.Lazy;
import org.springframework.stereotype.Component;

@Component
@Lazy(false)
public class ApplicationContextRegister  implements ApplicationContextAware {
    private static ApplicationContext APPLICATION_CONTEXT;

    /**
     * 设置spring上下文  *  * @param applicationContext spring上下文  * @throws BeansException  * author:huochengyan https://blog.csdn.net/u010919083
     */

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        APPLICATION_CONTEXT = applicationContext;
    }

    public static ApplicationContext getApplicationContext() {
        return APPLICATION_CONTEXT;
    }
}

逻辑代码中使用方式

//websocket 使用service 层
                ApplicationContext act = ApplicationContextRegister.getApplicationContext();
                messagelogService=act.getBean(MessagelogService.class);
                int resultlog = messagelogService.insertIntoMessagelog(messagelog); //.insertIntoMessagelog(messagelog)是我的方法

方法二：

引用spring-websocket 的包，使用@ServerEndpoint注解

pom.xml

<properties>
     <spring.version>4.0.5.RELEASE</spring.version>
</properties>

<dependencies>

  <dependency>
    <groupId>javax.websocket</groupId>
    <artifactId>javax.websocket-api</artifactId>
    <version>1.0</version>
    <scope>provided</scope>
  </dependency>

  <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-websocket</artifactId>
    <version>${spring.version}</version>
  </dependency>

</dependencies>

websocket实体类加注解

//在websocket类添加configurator = SpringConfigurator.class
//当创建好一个（服务）端点之后，将它以一个指定的URI发布到应用当中，这样远程客户端就能连接上它了
@ServerEndpoint(value="/websockets",configurator = SpringConfigurator.class)
public class MyWebSocket {

}

 有网友说 configurator = GetHttpSessionConfiguratorNew.class 这个配置，大家也可以试试。
