大家好，我是烤鴨：? ?

? ? 關于springboot war包部署tomcat。

? ? 環境：

????? ? springboot 2.0.3.RELEASE

????????apache-tomcat-8.5.32

1.? ? 修改pom

<?xml version="1.0" encoding="UTF-8"?> <project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://maven.apache.org/POM/4.0.0"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.0.3.RELEASE</version></parent><groupId>com.xxx.xxx</groupId><version>1.0.0-SNAPSHOT</version><artifactId>xxx_xxxx_interface</artifactId><packaging>war</packaging><name>xxx_xxxx_interface</name><description>xxx接口</description><properties><maven.compiler.source>1.8</maven.compiler.source><maven.compiler.target>1.8</maven.compiler.target><maven.compiler.encoding>UTF-8</maven.compiler.encoding><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><project.build.locales>zh_CN</project.build.locales></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency></dependencies><profiles><profile><!--本地開發環境 --><id>dev</id><properties><profiles.active>dev</profiles.active></properties><activation><activeByDefault>true</activeByDefault></activation></profile><profile><!--測試環境 --><id>test</id><properties><profiles.active>test</profiles.active></properties></profile><profile><!--生產環境 --><id>pro</id><properties><profiles.active>pro</profiles.active></properties></profile></profiles><build><finalName>xxxx_interface</finalName> <!-- 指定package生成的文件名為my-spring-boot.jar --><resources><!-- 所有環境配置文件過濾 --><resource><directory>src/main/resources</directory><filtering>true</filtering><excludes><exclude>test/*</exclude><exclude>pro/*</exclude><exclude>dev/*</exclude></excludes></resource><!-- 指定環境配置文件導入 --><resource><directory>src/main/resources/${profiles.active}</directory></resource></resources><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><configuration><source>1.8</source><target>1.8</target><delimiters><delimiter>@</delimiter></delimiters><useDefaultDelimiters>false</useDefaultDelimiters><archive><manifest><addClasspath>true</addClasspath><useUniqueVersions>false</useUniqueVersions><classpathPrefix>lib/</classpathPrefix><mainClass>xxx.xxx.xxxInterfaceMainApplication</mainClass></manifest><manifestEntries><version>${project.version}</version></manifestEntries></archive></configuration></plugin></plugins></build> </project>

網上很多人都說需要再加忽略內置tomcat,或者servlet.api的包，其實都不需要。

主要就是? ?

???? ????????<parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.0.3.RELEASE</version></parent> ????????????????<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency> <packaging>war</packaging>

<parent> ????spring-boot-starter-parent????</parent>

<dependency>? ? ? ? ?spring-boot-starter-web????</dependency>

?<packaging> war </packaging>

2.? ? 修改啟動方法

package com.xxx.xxxx.config;import java.util.ArrayList; import java.util.List; import java.util.concurrent.Executors;import javax.annotation.PostConstruct;import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.servlet.support.SpringBootServletInitializer; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.ComponentScan.Filter; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.FilterType; import org.springframework.stereotype.Controller;@Configuration @EnableAutoConfiguration @ComponentScan(value = "com.xxx.xxxx", excludeFilters = { @Filter(Controller.class),@Filter(type = FilterType.ASSIGNABLE_TYPE, value = { RootConfiguration.class }) }) @MapperScan({"com.xxx.xxxx.dao"}) public class RootConfiguration extends SpringBootServletInitializer {@PostConstructpublic void postConstruct() {}@Overrideprotected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {return configureApplication(builder);}public static void main(String[] args) {configureApplication(new SpringApplicationBuilder()).run(args);}private static SpringApplicationBuilder configureApplication(SpringApplicationBuilder builder) {return builder.sources(RootConfiguration.class);}}

主要就是繼承?SpringBootServletInitializer?，重寫?configure 方法。

3.? ? 問題及猜想

? ? 之前的項目就是這么配置的，用的springboot 1.5.6.RELEASE，是沒有問題的。

? ? ?改了新項目，升級了springboot，也加了很多東西，項目就起不來了。

? ? ?本地run方法運行是沒有問題的。

? ? 3.1 問題?：

? ? ????啟動卡死：

? ? 這是tomcat下log日志的最后幾行，乍一看并沒有什么問題。但是總覺得哪里不對。訪問tomcat也訪問不到。

或者卡在這：

或者卡在springboot讀取banner之后。

? ? 這種問題真的是難找，也不報錯。

? ? 3.2????猜想：

? ??? ? 1????是不是springboot版本升級導致的問題，第一時間降版本，無效。

????? ? 2????是不是引了多余的包，導致jar包沖突，解決了之后，無效。

????? ? 3????tomcat本身問題，換tomcat版本，保證tomcat是沒問題的，無效。

????? ? ????如果這些都做了，還是無效的話，考慮一下是不是代碼的問題。

我嘗試注釋掉部分代碼，再打包啟動，如果成功了，就說明代碼部分有問題。最后找到了代碼中的問題。

問題代碼：

/*** * 定時任務回調輪詢*/ @Component public class TaskUpdateNotify implements CommandLineRunner {public static Log logger = LogFactory.getLog(TaskUpdateNotify.class);public static final long timeFlag = 1000;@Autowiredprivate RedisClient redisClient;@Autowiredprivate ThreadHandler threadHandler;/*** 25小時以內完成8次通知（通知的間隔頻率一般是：4m,10m,10m,1h,2h,6h,15h） 異步通知回調*/@Overridepublic void run(String... args) throws Exception {while (true) {// 先處理發二維碼threadHandler.doNotifyAgainHandler(); //threadHandler.doPayNotifyAgainHandler(); //多線程方法//線成休息 1 minTimeUnit.MINUTES.sleep(1);}} }

我懷疑原因是在實現?CommandLineRunner?接口，并在我在方法中?TimeUnit.MINUTES.sleep(1)?。

????? ? 之后把這個方法改成了定時任務，又取消了線程sleep，就可以啟動了。

最后貼一下：

????啟動成功的日志最后幾行，應該是有tomcat容器啟動的。

4.? ? 總結

? ? 如果有報錯信息一切都好說，最怕的就是這樣，找不到原因。只能一點點摸索，算是分享一下吧。每個人的原因不可能一樣。這種問題只能慢慢找了。多嘗試幾次，如果還是找不到。

? ? 就用 jar包方式 運行 springboot 項目。如果有 靜態頁面，就前后端分離，簡單的方式 Nginx。
