Spring Boot部署到Tomcat过程中遇到的问题汇总

作者:Big丶Fine

这篇文章主要给大家分享了关于Spring Boot部署到Tomcat过程中遇到的一些问题,文中将解决的方法介绍非常详细,对同样遇到这个问题的朋友具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧。

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……

</project> 

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
