【转】SpringBoot 2.0.0新版和SpringBoot1.5.2版本中Tomcat配置的差别

https://blog.csdn.net/wd2014610/article/details/79587161

2018年春SpringBoot 2.0.0 新版本有了很多新的改变，其中Tomcat配置上也有了很大改变
1、之前老的版本TomcatEmbeddedServletContainerFactory取的是这个类

2、在SpringBoot 2.0.0框架中，已经没有类TomcatEmbeddedServletContainerFactory了

3、在老版本的Tomcat配置中，构造tomcatFactory的bean

@Bean
public TomcatEmbeddedServletContainerFactory tomcatFactory() {
TomcatEmbeddedServletContainerFactory tomcatFactory = new TomcatEmbeddedServletContainerFactory();
tomcatFactory.addConnectorCustomizers(new GwsTomcatConnectionCustomizer());
return tomcatFactory;
}

4、那么早SpringBoot 2.0.0中该怎么构建呢？
去到SpringBoot官方文档这里写链接内容、找到Tomcat配置

5、最新的已经有了全新的类了

6、事例

7、那么就可以用全新的ServletWebServerFactory类来构造Tomcat的配置了

@Bean
public ServletWebServerFactory servletContainer() {
TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory();
tomcat.addConnectorCustomizers(new GwsTomcatConnectionCustomizer());
return tomcat;
}

8、最后附上全新的Tomcat配置

package com.gws.configuration;

import org.apache.catalina.connector.Connector;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.web.embedded.tomcat.TomcatConnectorCustomizer;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.boot.web.servlet.MultipartConfigFactory;
import org.springframework.boot.web.servlet.server.ServletWebServerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.servlet.MultipartConfigElement;

/**

*
* @version
* @author
*
*/
@Configuration
public class TomcatConfig {

@Value("${spring.server.port}")
private String port;
@Value("${spring.server.acceptorThreadCount}")
private String acceptorThreadCount;
@Value("${spring.server.minSpareThreads}")
private String minSpareThreads;
@Value("${spring.server.maxSpareThreads}")
private String maxSpareThreads;
@Value("${spring.server.maxThreads}")
private String maxThreads;
@Value("${spring.server.maxConnections}")
private String maxConnections;
@Value("${spring.server.protocol}")
private String protocol;
@Value("${spring.server.redirectPort}")
private String redirectPort;
@Value("${spring.server.compression}")
private String compression;
@Value("${spring.server.connectionTimeout}")
private String connectionTimeout;

@Value("${spring.server.MaxFileSize}")
private String MaxFileSize;
@Value("${spring.server.MaxRequestSize}")
private String MaxRequestSize;

@Bean
public ServletWebServerFactory servletContainer() {
TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory();
tomcat.addConnectorCustomizers(new GwsTomcatConnectionCustomizer());
return tomcat;
}

@Bean
public MultipartConfigElement multipartConfigElement() {
MultipartConfigFactory factory = new MultipartConfigFactory();
// 单个数据大小
factory.setMaxFileSize(MaxFileSize); // KB,MB
/// 总上传数据大小
factory.setMaxRequestSize(MaxRequestSize);
return factory.createMultipartConfig();
}

/**

* 默认http连接

* @version
* @author liuyi 2016年7月20日 下午7:59:41

*/
public class GwsTomcatConnectionCustomizer implements TomcatConnectorCustomizer {

public GwsTomcatConnectionCustomizer() {
}

@Override
public void customize(Connector connector) {
connector.setPort(Integer.valueOf(port));
connector.setAttribute("connectionTimeout", connectionTimeout);
connector.setAttribute("acceptorThreadCount", acceptorThreadCount);
connector.setAttribute("minSpareThreads", minSpareThreads);
connector.setAttribute("maxSpareThreads", maxSpareThreads);
connector.setAttribute("maxThreads", maxThreads);
connector.setAttribute("maxConnections", maxConnections);
connector.setAttribute("protocol", protocol);
connector.setAttribute("redirectPort", "redirectPort");
connector.setAttribute("compression", "compression");
}
}
}

9、最后在application.properties，进行配置

#嵌入tomcat配置
spring.server.port=8095
#和CPU数
spring.server.acceptorThreadCount=4
spring.server.minSpareThreads=50
spring.server.maxSpareThreads=50
spring.server.maxThreads=1000
spring.server.maxConnections=10000
#10秒超时
spring.server.connectionTimeout=10000
spring.server.protocol=org.apache.coyote.http11.Http11Nio2Protocol
spring.server.redirectPort=443
spring.server.compression=on
#文件请求大小
spring.server.MaxFileSize=300MB
spring.server.MaxRequestSize=500MB
