启动类报Error creating bean with name 'configurationPropertiesBeans' defined in class path resource

启动类报Error creating bean with name 'configurationPropertiesBeans' defined in class path resource 是由于在Spring Boot项目中，无法创建名为'configurationPropertiesBeans'的bean所引起的错误。
根据提供的引用内容，这个问题可能由于Spring Boot和Spring Cloud Alibaba版本之间的不兼容性导致。根据引用中的建议，将Spring Boot的版本从2.5.11改为2.3.12.RELEASE可能解决这个问题。
此外，还可以检查启动类中是否存在错误的配置或依赖项，并确保它们与使用的版本兼容。

Error creating bean with name rabbitAdmin defined in class path resource

解决 Spring Boot 创建 rabbitAdmin Bean 失败的问题
当遇到错误提示 "Error creating bean with name 'rabbitAdmin'" 时，通常意味着在初始化 RabbitMQ 的管理组件过程中出现了异常。这类问题的原因多种多样，常见的原因包括但不限于配置文件中的连接参数设置不当、依赖库缺失或版本冲突。
配置检查
确保 application.properties 或 application.yml 文件中包含了正确的 RabbitMQ 连接信息：
spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

如果使用的是自定义的配置类来创建 RabbitAdmin 实例，则需确认该类是否正确实现了必要的逻辑[^1]。
依赖验证
对于因缺少必要依赖而导致的 NoClassDefFoundError 类型的错误，应仔细核对 pom.xml (Maven) 或 build.gradle (Gradle)，保证引入了所有必需的支持包。特别是针对 Redis 和 GSON 库引发的相关案例表明，某些第三方客户端工具集可能需要额外声明其对应的 Java API 接口实现[^2][^3]。
例如，在 Maven 中添加如下依赖可以解决部分由 Jedis 引起的问题：
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>${jedis.version}</version>
</dependency>

而对于 GSON 版本冲突的情况，可以通过排除默认加载路径下的特定模块并指定兼容版本的方式来处理：
@SpringBootApplication(exclude = {GsonAutoConfiguration.class})
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}

不过需要注意的是，上述措施仅作为一般指导原则；具体到 rabbitAdmin Bean 初始化失败的情形下，还需要进一步排查具体的堆栈跟踪日志以定位确切根源所在。

springboot使用websocket报错Error creating bean with name webSocketHandlerMapping defined in class path resource [

Spring Boot WebSocket Bean Creation Error
When encountering an error while creating a bean named webSocketHandlerMapping in a Spring Boot application using WebSocket, several factors could contribute to this issue. The configuration settings provided offer insights into resource handling but do not directly address WebSocket configurations[^1]. However, understanding how beans are configured and managed within the context of WebSockets is crucial.
In Spring Boot applications utilizing WebSocket, ensuring proper registration of handlers and mappings plays a vital role. If there's an error during the creation of the webSocketHandlerMapping bean, it often indicates misconfiguration or missing dependencies related specifically to WebSocket support rather than general resource management settings mentioned earlier.
To resolve issues surrounding the creation of the webSocketHandlerMapping bean:

Verify that all necessary WebSocket-related dependencies have been included in the project’s build file (e.g., Maven POM or Gradle).

Ensure correct annotations such as @EnableWebSocket, along with appropriate handler classes implementing interfaces like WebSocketHandler.

Check for any conflicting configurations between standard MVC components and those specific to WebSocket functionality.

Additionally, when configuring controllers interacting over WebSocket connections, consider patterns similar to RESTful service implementations where methods respond appropriately based on incoming requests[^2]:
@Configuration
@EnableWebSocket
public class WebSocketConfig implements WebSocketConfigurer {

@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
registry.addHandler(myWebSocketHandler(), "/ws").setAllowedOrigins("*");
}

@Bean
public MyWebSocketHandler myWebSocketHandler() {
return new MyWebSocketHandler();
}
}

For comprehensive testing purposes concerning asynchronous behaviors associated with WebSocket communications, tools listed provide valuable assistance through simplifying test scenarios involving concurrency and network interactions without relying solely upon actual external services[^3]:
// Example Test Using Awaitility for Asynchronous Operations Verification
@Test
public void shouldReceiveMessageViaWebSocket() throws Exception {
given().
contentType(JSON).
body(new Message("test").
expect().
statusCode(200);

await().atMost(5, TimeUnit.SECONDS).until(() -> !receivedMessages.isEmpty());
}
