java.lang.IllegalStateException：无法加载ApplicationContext,springboot设置

Question

以下是错误消息

java.lang.IllegalStateException：无法加载ApplicationContext

一个使用elasticSearch、mysql、redis等的Spingboot项目，谷歌有很多，但他只是一个新的Spingboot。网上的东西不管用。我不知道怎么改。

应与ES的配置相关

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.net.InetAddress;
import java.net.UnknownHostException;

@Configuration
public class ESConfig {

    @Value("${elasticsearch.host:127.0.0.1}")
    private String host;

    @Value("${elasticsearch.port:9300}")
    private int port;

    @Value("${elasticsearch.cluster.name:elasticsearch}")
    private String clusterName;

    public String getHost() {
        return this.host;
    }

    public int getPort() {
        return this.port;
    }

    @Bean
    public Client client() {
        TransportClient client = null;

        Settings settings = Settings.builder()
            .put("cluster.name", clusterName)
            .put("client.transport.ignore_cluster_name", false)
            .build();

        try {
            client = new PreBuiltTransportClient(settings)
                .addTransportAddress(new TransportAddress(InetAddress.getByName(host), port));
        } catch (UnknownHostException e) {
            e.printStackTrace();
        }

        return client;
    }
}

Answer 1

这是您的例外情况：

原因：org.springframework.beans.factory.unsatisfieddependencyexception：创建名为“woker logcontroller”的bean时出错：通过字段“client”表示的未满足的依赖项；嵌套异常为org.springframework.beans.factory.BeanCreationException：创建类路径资源中定义的名称为“client”的bean时出错

而且

此问题在本环节已有报道。没有用弹性搜索来面对这个问题。以下方法可以解决您的问题，但这可能与webserver相关。看看这个。

@Component
public class ElasticSearchConfiguration implements InitializingBean {
    static {
        System.setProperty("es.set.netty.runtime.available.processors", "false");
    }

    @Override
    public void afterPropertiesSet() throws Exception {
        System.out.println(System.getProperty("es.set.netty.runtime.available.processors"));
    }
}
