第一步：
pom.xml配置
如果使用tomcat服务器，则配置如下：
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
</dependencies>
如果使用undertow服务器，则配置如下：因为spring boot默认配置为tomcat:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<!-- 若使用log4j2 -->
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
再添加dependency依赖：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-undertow</artifactId>
第二步，再在定制tomcat/undertow服务器
/**

package com.lz.ovuola.general.util.tomcat;
import org.apache.catalina.connector.Connector;
import org.apache.coyote.http11.Http11NioProtocol;
import org.springframework.boot.context.embedded.EmbeddedServletContainerFactory;
import org.springframework.boot.context.embedded.tomcat.TomcatConnectorCustomizer;
import org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
/**

*/
@Configuration
@ConfigurationProperties(prefix = "tomcat")
public class CustomTomcatEmbeddedCustomizer {
private int maxThreads;
private int minSpareThreads;
private int acceptCount;
private int connectionTimeout;
private String URIEncoding = "UTF-8";
private boolean disableUploadTimeout;
private boolean enableLookups;
private String compression;
private int compressionMinSize;
private String compressableMimeType;
/**
* 订制内嵌tomcat容器
*/
@Bean
public EmbeddedServletContainerFactory servletContainer() {
TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory();
factory.addConnectorCustomizers(new MyTomcatConnectorCustomizer());
return factory;
}
class MyTomcatConnectorCustomizer implements TomcatConnectorCustomizer {
public void customize(Connector connector) {
Http11NioProtocol protocol = (Http11NioProtocol) connector
.getProtocolHandler();
// 设置最大连接数
protocol.setMaxThreads(maxThreads);
protocol.setConnectionTimeout(connectionTimeout);
protocol.setMinSpareThreads(minSpareThreads);
protocol.setAcceptorThreadCount(acceptCount);
protocol.setDisableUploadTimeout(disableUploadTimeout);
protocol.setCompression(compression);
protocol.setCompressionMinSize(compressionMinSize);
protocol.setCompressableMimeType(compressableMimeType);
// connector.setURIEncoding(URIEncoding);
connector.setEnableLookups(enableLookups);
}
}
public int getMaxThreads() {
return maxThreads;
}
public void setMaxThreads(int maxThreads) {
this.maxThreads = maxThreads;
}
public int getMinSpareThreads() {
return minSpareThreads;
}
public void setMinSpareThreads(int minSpareThreads) {
this.minSpareThreads = minSpareThreads;
}
public int getAcceptCount() {
return acceptCount;
}
public void setAcceptCount(int acceptCount) {
this.acceptCount = acceptCount;
}
public int getConnectionTimeout() {
return connectionTimeout;
}
public void setConnectionTimeout(int connectionTimeout) {
this.connectionTimeout = connectionTimeout;
}
public String getURIEncoding() {
return URIEncoding;
}
public void setURIEncoding(String uRIEncoding) {
URIEncoding = uRIEncoding;
}
public boolean isDisableUploadTimeout() {
return disableUploadTimeout;
}
public void setDisableUploadTimeout(boolean disableUploadTimeout) {
this.disableUploadTimeout = disableUploadTimeout;
}
public boolean isEnableLookups() {
return enableLookups;
}
public void setEnableLookups(boolean enableLookups) {
this.enableLookups = enableLookups;
}
public String getCompression() {
return compression;
}
public void setCompression(String compression) {
this.compression = compression;
}
public int getCompressionMinSize() {
return compressionMinSize;
}
public void setCompressionMinSize(int compressionMinSize) {
this.compressionMinSize = compressionMinSize;
}
public String getCompressableMimeType() {
return compressableMimeType;
}
public void setCompressableMimeType(String compressableMimeType) {
this.compressableMimeType = compressableMimeType;
}
}
或者是 undertow,测试只要启动一个就行
//package com.lz.ovuola.general.util.tomcat;
//
//import io.undertow.Undertow.Builder;
//
//import org.springframework.boot.context.embedded.EmbeddedServletContainerFactory;
//import org.springframework.boot.context.embedded.undertow.UndertowBuilderCustomizer;
//import org.springframework.boot.context.embedded.undertow.UndertowEmbeddedServletContainerFactory;
//import org.springframework.boot.context.properties.ConfigurationProperties;
//import org.springframework.context.annotation.Bean;
//import org.springframework.context.annotation.Configuration;
//
//@Configuration
//public class CustomUndertowEmbeddedCustomizer {
//
//
@Bean
//
public EmbeddedServletContainerFactory servletContainer() {
//
UndertowEmbeddedServletContainerFactory factory = new UndertowEmbeddedServletContainerFactory();
//
factory.addBuilderCustomizers(new UndertowBuilderCustomizer() {
//
//
@Override
//
public void customize(Builder builder) {
//
builder.addHttpListener(8080, "127.0.0.1");
//
}
//
//
});
//
return factory;
//
}
//
// }
第三步，在application -runAs -run as configuratuion-Arguments添加：--用于jconsole或者是visualVM监控，推荐使用后者
-Djava.rmi.server.hostname=127.0.0.1 --ip地址
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port="9093" --端口号
-Dcom.sun.management.jmxremote.authenticate="false"
第四步，采用visualVM监控同一个服务，分别开启tomcat/undertow容器，注意两者在application.propertites参数尽量相同，以便观察稳定性
第5步，打开jemter压力测试某一接口，观察堆内存、线程数、cpu等指标。
