spring boot war包服务器部署无法运行
war包一般都是丢到webapps下就会自动运行了，但是对于无法运行的war包不知道怎么排查问题，不能看到日志十分恶心，所以想了一个简单的办法：
1.ps -ef | grep tomcat
root 901 1 0 00:21 ? 00:00:39 /usr/bin/java -Djava.util.logging.config.file=/usr/share/tomcat/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -server -XX:PermSize=256M -XX:MaxPermSize=1024m -Xms512M -Xmx1024M -XX:MaxNewSize=256m -Djava.endorsed.dirs=/usr/share/tomcat/endorsed -classpath /usr/share/tomcat/bin/bootstrap.jar:/usr/share/tomcat/bin/tomcat-juli.jar -Dcatalina.base=/usr/share/tomcat -Dcatalina.home=/usr/share/tomcat -Djava.io.tmpdir=/usr/share/tomcat/temp org.apache.catalina.startup.Bootstrap start
2.kill tomcat_pid(901)
3.手动执行命令重启tomcat:
/usr/bin/java -Djava.util.logging.config.file=/usr/share/tomcat/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -server -XX:PermSize=256M -XX:MaxPermSize=1024m -Xms512M -Xmx1024M -XX:MaxNewSize=256m -Djava.endorsed.dirs=/usr/share/tomcat/endorsed -classpath /usr/share/tomcat/bin/bootstrap.jar:/usr/share/tomcat/bin/tomcat-juli.jar -Dcatalina.base=/usr/share/tomcat -Dcatalina.home=/usr/share/tomcat -Djava.io.tmpdir=/usr/share/tomcat/temp org.apache.catalina.startup.Bootstrap start
4.然后我们就能看到启动日志了：
[root@water ~]# ps -ef | grep tomcat

。。。接下来就根据报错来解决问题。
5.也可以编译成jar包，然后放到服务器上java -jar xxx.jar运行然后看出错日志。
但是遇到这spring boot部署后没有报错。。。。然后查了各种资料，解决办法如下：
我都启动类方法如下：
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
改为：
@SpringBootApplication
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(Application.class);
}
}
备注：
使用外部Tomcat部署访问的时候，application.properties(或者application.yml)中配置的
server.port=
server.servlet.context-path=
将失效，需要使用使用tomcat的端口进行访问，例如：
http://ip:8080/项目名/接口
