002--SpringBoot的花式玩法

话题一：使用自定义Banner文字

• 1.Banner生成网址：http://patorjk.com/software/taag/#p=display&f=Jacky&t=unmi.cc
• 2.生成文字之后，保存到banner.txt中
• 3.然后放入到项目主目录，重启即可

---

话题二：不使用Banner文字

setBannerMode(Mode.OFF);

public static void main(String[] args) {
        SpringApplication application = new SpringApplication(HelloApplication.class);
        application.setBannerMode(Mode.OFF);
        application.run(args);
    }

---

话题三：修改SpringBoot的默认端口

• 1.添加默认配置文件application.property或者application.yml
• 2.添加配置更改（以application.yml为例）

server:
  port: 8088

• 3.重启程序即可

---

话题四：修改DispatcherServlet的规则

默认是/，现在可以修改成/api/

server:
  port: 8088
  servlet-path: /api/*

---

话题五：引入xml文件

• Properties文件：mongodb-context-config.properties

mongo.host=www.wenbronk.com
mongo.port=27017
mongo.connectionsPerHost=8
mongo.threadsAllowedToBlockForConnectionMultiplier=4
mongo.connectTimeout=1000
mongo.maxWaitTime=1500
mongo.autoConnectRetry=true
mongo.socketKeepAlive=true
mongo.socketTimeout=1500
mongo.slaveOk=true
mongo.writeNumber=1
mongo.riteTimeout=0
mongo.writeFsync=true

• XML文件：mongodb-context.xml

<?xml version="1.0" encoding="UTF-8"?>

            write-timeout="0" write-fsync="true"/> 
    </mongo:mongo>
    <!-- 设置使用的数据库 名-->

    </bean>
</beans>

• Java文件：XMLSource.java

@Configuration
@ImportResource(locations={"classpath:mongodb/mongodb-context.xml"})
public class XMLSource {
 
}
