springboot 集成 jconsole 性能监控

 从Java 5开始 引入了 JConsole。JConsole 是一个内置 Java 性能分析器。

需要在项目中增加JMX 监控：

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.DependsOn;
import org.springframework.jmx.support.ConnectorServerFactoryBean;
import org.springframework.remoting.rmi.RmiRegistryFactoryBean;

@Configuration
class MqReceiverConfigureRMI {

    @Value("${jmx.rmi.hostname}")
    private String rmiHost;

    @Value("${jmx.rmi.port}")
    private Integer rmiPort;

    @Bean
    public RmiRegistryFactoryBean rmiRegistry() {
        final RmiRegistryFactoryBean rmiRegistryFactoryBean = new RmiRegistryFactoryBean();
        rmiRegistryFactoryBean.setPort(rmiPort);
        rmiRegistryFactoryBean.setAlwaysCreate(true);
        return rmiRegistryFactoryBean;
    }

    @Bean
    @DependsOn("rmiRegistry")
    public ConnectorServerFactoryBean connectorServerFactoryBean() throws Exception {
        final ConnectorServerFactoryBean connectorServerFactoryBean = new ConnectorServerFactoryBean();
        connectorServerFactoryBean.setObjectName("connector:name=rmi");
        connectorServerFactoryBean.setServiceUrl(String.format("service:jmx:rmi://%s:%s/jndi/rmi://%s:%s/jmxrmi", rmiHost, rmiPort, rmiHost, rmiPort));
        return connectorServerFactoryBean;
    }
}

然后win+R 输入cmd进入命令行，输入jconsole，即可弹出连接框：
输入配置的hostname和prot，点击连接即可：
