1、Tomcat配置

Spring Boot默认内嵌的Tomcat为Servlet容器,所以本节只讲对Tomcat配置,其实本节的配置对Tomcat、Jetty和Undertow都是通用的。

1.1 配置Tomcat

关于Tomcat的所有属性都在org.springframework.boot.autoconfigure.web.ServerProperties配置类中做了定义,我们只需在application.properties配置属性做配置即可。通用的Servlet容器配置都以"server"作为前缀,而Tomcat特有配置都以"server.tomcat"作为前缀。下面举一些常用的例子。

配置servlet容器

server.port = #配置程序端口,默认为8080
server.session-timeout=#用户session过期,以秒为单位
server.context-path= #配置访问路径,默认为/

配置Tomcat

server.tomcat-uri-encoding = #配置Tomcat编码,默认为UTF-8
server.tomcat.compression = #Tomcat是否开启压缩,默认为关闭off

1.2 代码配置Tomcat

如果你需要通过代码的方式配置servlet容器,则可以注册一个实现EmbeddedServletContainerCustomizer接口的Bean,若想直接配置Tomcat、Jetty、Undertow,则可以直接定义TomcatEmbeddedServletContainerFactor、JettyEmbeddedServletContainerFactor、UndertowEmbeddedServletContainerFactor。
