這篇文章主要給大家分享了關(guān)于Spring Boot部署到Tomcat過(guò)程中遇到的一些問(wèn)題，文中將解決的方法介紹非常詳細(xì)，對(duì)同樣遇到這個(gè)問(wèn)題的朋友具有一定的參考學(xué)習(xí)價(jià)值，需要的朋友們下面隨著小編來(lái)一起學(xué)習(xí)學(xué)習(xí)吧。

前言

Spring Boot項(xiàng)目一般都是內(nèi)嵌tomcat或者jetty服務(wù)器運(yùn)行，很少用war包部署到外部的服務(wù)容器，即使放到linux中，一般也是直接啟動(dòng)Application類(lèi)，但是有些時(shí)候我們需要部署到外部的服務(wù)器，這對(duì)于Spring Boot來(lái)說(shuō)卻有點(diǎn)麻煩

下面就記錄下自己部署的第一個(gè)SpringBoot項(xiàng)目到Tomcat中遇到的問(wèn)題，三個(gè)地方需要注意：頭疼……

詳細(xì)如下：

1、SpringBoot有自己內(nèi)置Tomcat容器，所以要告訴它不使用內(nèi)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類(lèi)需要如下改動(dòng)，其中exclude是忽略數(shù)據(jù)庫(kù)的注解（我沒(méi)弄數(shù)據(jù)庫(kù)）：

@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！我開(kāi)始服務(wù)器用的jdk1.7，本地環(huán)境用的1.8，結(jié)果本地怎么調(diào)試運(yùn)行都正常，服務(wù)器tomcat啟動(dòng)正常，jsp訪問(wèn)都正常，接口全部404，控制臺(tái)也沒(méi)有出現(xiàn)SpringBoot的標(biāo)示?。。?！研究了一整天……頭疼……

Application類(lèi)：

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請(qǐng)求：

@RestController 
@RequestMapping 
public class LoginController { 
 @RequestMapping("/hello/{myName}") 
 String index(@PathVariable String myName) { 
 return "Hello "+myName+"!!!"; 
 } 
}

application.properties我這里只配置了端口，然而部署到tomcat以后這里就不起作用了：
