springboot去掉内置tomcat使用外部tomcat容器

（1）启动入口部分Application

public class XXXXXXApplication
        extends SpringBootServletInitializer
{
//原来的入口注掉
//	public static void reg(String[] args) {
//		ConfigurableApplicationContext context = SpringApplication.run(SepaBeanApplication.class, args);
//		SpringUtil.setApplicationContext(context);
//	}
	@Override
   protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        // 注意这里要指向原先用main方法执行的Application启动类
        return builder.sources(SepaBeanApplication.class);
   }
    @Override
    protected WebApplicationContext run(SpringApplication application) {
        SpringUtil.setApplicationContext(application.run(new String[0]));
       return (WebApplicationContext)SpringUtil.getApplicationContext();
    }
}

（2）parent的pom文件打包部分

		
			
				src/main/java
				
					**/*.properties
					**/*.xml
				
				false
			
			
				src/main/resources
				
					*.*
					**/*.*
				
				
					*.*.bak
					**/*.bak
				
				false
			
		


		

			
				org.apache.maven.plugins
				maven-source-plugin
				
					
						attach-sources
						
							jar
						
					
				
			
			
				maven-compiler-plugin
				
					1.8
					1.8
					UTF-8
				
			
		
	

（3）需要打包的web的pom文件部分
改成打war包即可

    SepaBean-Web
    war

（4）如果使用了log4j作为日志输出的
也需要修改log4j的properties文件

log4j.rootLogger=debug, stdout, logFile, errorFile
#控制台输出
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss,SSS} [%c]-[%p] %m%n
log4j.appender.CONSOLE.Encoding=UTF-8


#日志文件输出  超过1M产生新log文件
log4j.appender.logFile=org.apache.log4j.RollingFileAppender
#log4j.appender.logFile.File=${catalina.base}/logs/log.log
log4j.appender.logFile.File=../logs/log.log
log4j.appender.logFile.MaxFileSize=20000KB
log4j.appender.logFile.MaxBackupIndex=10
log4j.appender.logFile.layout=org.apache.log4j.PatternLayout
log4j.appender.logFile.layout.ConversionPattern=%n%-d{yyyy-MM-dd HH:mm:ss}%n[%p]-[Thread: %t]-[%C.%M()]: %m%n
log4j.appender.ROLLING_FILE.Encoding=UTF-8

#报错输出
log4j.appender.errorFile=org.apache.log4j.DailyRollingFileAppender
#log4j.appender.errorFile.File=${catalina.base}/logs/error.log
log4j.appender.errorFile.File=../logs/error.log
log4j.appender.errorFile.Append = true
log4j.appender.errorFile.Threshold = ERROR
log4j.appender.errorFile.layout=org.apache.log4j.PatternLayout
log4j.appender.errorFile.layout.ConversionPattern=%n%-d{yyyy-MM-dd HH:mm:ss}%n[%p]-[Thread: %t]-[%C.%M()]: %m%n
log4j.appender.DAILY_ROLLING_FILE.Encoding=UTF-8
