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：

pom.xml

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：
