关于spring boot打包及其注意事项

spring boot打war包，部署到tomcat中

1.在pom.xml文件中加入“<packaging>war</packaging>”；



2.在build中加入war包名， “ <finalName>web</finalName>”如下：

<build>
<finalName>web</finalName>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>



3.在spring-boot-starter-tomcat中最好加入“<scope>provided</scope”



4.修改application，在注解了SpringBootApplication的类中，继承SpringBootServletInitializer，并重写configure方法，



注：如果项目启动时报异常“no springapplication sources have been defined.Either override the configure method or add an @Configuration annotation”，这是由于其他类也注解了SpringBootApplication，或者其他地方也创建了application。

5.用maven打包，生成war包。（eclipse：右键项目->run as->maven install）

6.将生成的war包，放入tomcat中运行即可。

以下是简单的pom.xml文件：
