前言
spring boot项目一般都是内嵌tomcat或者jetty服务器运行,很少用war包部署到外部的服务容器,即使放到linux中,一般也是直接启动application类,但是有些时候我们需要部署到外部的服务器,这对于spring boot来说却有点麻烦
下面就记录下自己部署的第一个springboot项目到tomcat中遇到的问题,三个地方需要注意:头疼……
详细如下:
1、springboot有自己内置tomcat容器,所以要告诉它不使用内置容器,不指定tomcat版本配置如下:
<dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-tomcat</artifactid> <scope>provided</scope> </dependency>
2、application类需要如下改动,其中exclude是忽略数据库的注解(我没弄数据库):
@springbootapplication(exclude = { datasourceautoconfiguration.class, datasourcetransactionmanagerautoconfiguration.class, hibernatejpaautoconfiguration.class}) public class application extends springbootservletinitializer { @override protected springapplicationbuilder configure(springapplicationbuilder application) { return application.sources(application.class); } public static void main(string[] args) throws exception { springapplication.run(application.class, args); } }
3、jdk版本要一直!我开始服务器用的jdk1.7,本地环境用的1.8,结果本地怎么调试运行都正常,服务器tomcat启动正常,jsp访问都正常,接口全部404,控制台也没有出现springboot的标示!!!!研究了一整天……头疼……
我的代码:

application类:
package wechatservice.app; import org.springframework.boot.springapplication; import org.springframework.boot.autoconfigure.springbootapplication; import org.springframework.boot.autoconfigure.jdbc.datasourceautoconfiguration; import org.springframework.boot.autoconfigure.jdbc.datasourcetransactionmanagerautoconfiguration; import org.springframework.boot.autoconfigure.orm.jpa.hibernatejpaautoconfiguration; import org.springframework.boot.builder.springapplicationbuilder; import org.springframework.boot.web.support.springbootservletinitializer; import org.springframework.web.bind.annotation.requestmapping; import org.springframework.web.bind.annotation.restcontroller; @springbootapplication(exclude = { datasourceautoconfiguration.class, datasourcetransactionmanagerautoconfiguration.class, hibernatejpaautoconfiguration.class}) public class application extends springbootservletinitializer { @override protected springapplicationbuilder configure(springapplicationbuilder application) { return application.sources(application.class); } public static void main(string[] args) throws exception { springapplication.run(application.class, args); } }
hello请求:
@restcontroller @requestmapping public class logincontroller { @requestmapping("/hello/{myname}") string index(@pathvariable string myname) { return "hello "+myname+"!!!"; } }
application.properties我这里只配置了端口,然而部署到tomcat以后这里就不起作用了:
server.port = 80
