springboot内嵌了tomcat容器,可以通过3中方式来修改tomcat。
(1)修改application.properties文件中属性,比如:
server.port=8081 server.address=127.0.0.1 server.tomcat.accesslog.enabled=true server.tomcat.accesslog.directory=d\:/springboot/logs
端口:8081
绑定IP:上面的配置只能在浏览器输入localhost:8081或者127.0.0.1访问
启动tomcat的访问日志
tomcat访问日志的路径:D:\springboot\logs\access_log.2019-12-05.log,(2019-12-05是运行时间)
其他配置可以看源码:org.springframework.boot.autoconfigure.web.ServerProperties
(2)实现WebServerFactoryCustomizer接口,并装配到spring容器中,如下:
pom.xml
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.edu.spring</groupId> <artifactId>springboot_web</artifactId> <version>1.0.0</version> <name>springboot_web</name> <!-- FIXME change it to the project‘s website --> <url>http://www.example.com</url> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.4.RELEASE</version> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies> </project>
MyWebServerFactoryCustomizer.java
package com.edu.spring.springboot; import java.io.File; import org.apache.catalina.connector.Connector; import org.apache.catalina.valves.AccessLogValve; import org.apache.coyote.http11.Http11NioProtocol; import org.springframework.boot.web.embedded.tomcat.TomcatConnectorCustomizer; import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory; import org.springframework.boot.web.server.WebServerFactoryCustomizer; import org.springframework.stereotype.Component; @Component public class MyWebServerFactoryCustomizer implements WebServerFactoryCustomizer<TomcatServletWebServerFactory> { @Override public void customize(TomcatServletWebServerFactory factory) { factory.setPort(8888);//tomcat端口 factory.setBaseDirectory(new File("d:/temp/tomcat"));//缓存路径 factory.addContextValves(getLogAccessLogValue());//设置日志 factory.addConnectorCustomizers(new MyTomcatConnectorCustomizer());//tomcat自定义访问连接 } private AccessLogValve getLogAccessLogValue(){ AccessLogValve log=new AccessLogValve(); log.setDirectory("d:/temp/logs");//日志路径 log.setEnabled(true);//启用日志 log.setPattern("common");//输入日志格式 log.setPrefix("springboot-access-log");//日志名称 log.setSuffix(".txt");//日志后缀 return log; } } class MyTomcatConnectorCustomizer implements TomcatConnectorCustomizer{ @Override public void customize(Connector connector) { Http11NioProtocol protocal=(Http11NioProtocol)connector.getProtocolHandler(); protocal.setMaxConnections(20000);//最大连接数 protocal.setMaxThreads(500);//最大线程数 } }
UserController.java
package com.edu.spring.springboot; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController public class UserController { @RequestMapping("/user/home") public String home(){ System.out.println("============home============="); return "user home1"; } }
App.java
package com.edu.spring.springboot; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class App { public static void main(String[] args) { SpringApplication.run(App.class, args); } }
启动,浏览器输入:http://192.168.43.53:8888/user/home
(3)创建TomcatServletWebServerFactory的bean,如下:
WebServerConfiguration.java
package com.edu.spring.springboot; import javax.servlet.ServletContext; import javax.servlet.ServletException; import org.apache.catalina.valves.AccessLogValve; import org.springframework.boot.SpringBootConfiguration; import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory; import org.springframework.boot.web.server.ErrorPage; import org.springframework.boot.web.servlet.ServletContextInitializer; import org.springframework.boot.web.servlet.server.AbstractServletWebServerFactory; import org.springframework.context.annotation.Bean; import org.springframework.http.HttpStatus; @SpringBootConfiguration public class WebServerConfiguration { @Bean public AbstractServletWebServerFactory createServletWebServerFactory(){ TomcatServletWebServerFactory factory=new TomcatServletWebServerFactory(); factory.setPort(10008);//tomcat端口 factory.addErrorPages(new ErrorPage(HttpStatus.NOT_FOUND,"/404.html"));//设置状态码对应的错误页面 factory.addContextValves(getLogAccessLogValue());//设置日志 factory.addInitializers(new MyServletContext());//tomcat容器初始化时执行 return factory; } private AccessLogValve getLogAccessLogValue(){ AccessLogValve log=new AccessLogValve(); log.setDirectory("d:/temp/logs");//日志路径 log.setEnabled(true);//启用日志 log.setPattern("common");//输入日志格式 log.setPrefix("springboot-access-log");//日志名称 log.setSuffix(".txt");//日志后缀 return log; } } class MyServletContext implements ServletContextInitializer{ @Override public void onStartup(ServletContext servletContext) throws ServletException { // TODO Auto-generated method stub System.out.println("------------servletContext start------------"); } }
启动,浏览器输入:http://localhost:10008/user/home
