我正在尝试在我的spring项目中实现执行器(不是spring boot)。我在pom文件中添加了以下依赖项:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-actuator</artifactId>
<version>1.3.5.RELEASE</version>
</dependency>
还添加了以下类别:
import java.util.Collection;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.actuate.autoconfigure.EndpointAutoConfiguration;
import org.springframework.boot.actuate.autoconfigure.PublicMetricsAutoConfiguration;
import org.springframework.boot.actuate.endpoint.MetricsEndpoint;
import org.springframework.boot.actuate.endpoint.mvc.EndpointHandlerMapping;
import org.springframework.boot.actuate.endpoint.mvc.EndpointMvcAdapter;
import org.springframework.boot.actuate.endpoint.mvc.MvcEndpoint;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
@Configuration
@Import({EndpointAutoConfiguration.class, PublicMetricsAutoConfiguration.class})
public class SpringBootActuatorConfigBindings {
@Bean
@Autowired
public EndpointHandlerMapping endpointHandlerMapping(Collection<? extends MvcEndpoint> endpoints) {
return new EndpointHandlerMapping(endpoints);
}
@Bean
@Autowired
public EndpointMvcAdapter metricsEndPoint(MetricsEndpoint delegate) {
return new EndpointMvcAdapter(delegate);
}
}
但是在运行时,我遇到以下错误:

答案 0 :(得分:1)
如果您检查异常日志:
Caused by: java.lang.IllegalStateException: Failed to introspect annotated methods on class com.mycompany.ans.processor.bindings.SpringBootActuatorConfigBindings

Caused by: java.lang.NoClassDefFoundError:
org/springframework/web/servlet/mvc/method/annotation/RequestMappingHandlerMapping
at java.lang.ClassLoader.defineClass1(Native Method) ~[?:1.8.0_202]
...
您需要包括Spring Web mvc的依赖项,从该依赖项可以实现RequestMappingHandlerMapping
类。这是NoClassDefFoundError
的原因。
