SpringBoot集成HBase-client的票据认证

背景说明：在SpringBoot初使化时加载票据信息，拿着票据信息到HBase服务端进行认证，依赖文件

        
            org.apache.hbase
            hbase-client
            2.1.1
        

        
            org.springframework.data
            spring-data-hadoop-hbase
            2.5.0.RELEASE
        

1.MyServletContextListener 继承ServletContextListener，重写contextInitialized方法

@Configuration
public class MyServletContextListener implements ServletContextListener {
	
	//初始化
	public void contextInitialized(ServletContextEvent arg0) {
		System.out.println("-------------开始执行指定任务-------------------");
        //加载外部配置文件参数
//		File file = new File(System.getProperty("user.dir")+
        File.separator+"config"+File.separator+"hbase.properties");
		HbaseConfig.load("application.properties");
		try {
			new HBaseAPI().getConnection();// 连接HBase
		} catch (Exception e) {
			System.out.println("连接HBase 异常----------------------------" + "\n"
					+ e.getMessage());
		}
		System.out.println("--------------结束执行指定任务------------------");
	}
	
	//环境初始化
	public void contextDestroyed(ServletContextEvent arg0) {
		System.err.println("销毁程序");
	}
}

2.HbaseConfig类

import org.springframework.core.io.ClassPathResource;
import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.InputStream;
import java.util.Properties;

public class HbaseConfig {

    public static String QUORUM = "";

	public static String CLIENTPORT = "";

	public static String KEYTAB_PATH = "";

	public static String PRINCAL_NAME = "";

	public static String PRINCAL_SUFFIX = "";

	public static String KRB5_CONF = "";

    public static void load(String path) {
        try {
            ClassPathResource cpr = new ClassPathResource(path);
            Properties prop = new Properties();
            InputStream in;
            try {
                in = new BufferedInputStream(cpr.getInputStream());
                prop.load(in);
                in.close();
            } catch (Exception e) {
                e.printStackTrace();
            }

            // 读取配置
            QUORUM = prop.getProperty("hbase.quorum").trim();
            CLIENTPORT = prop.getProperty("hbase.clientPort").trim();
            KEYTAB_PATH = prop.getProperty("hbase.keytab_path").trim();
            PRINCAL_NAME = prop.getProperty("hbase.princal_name").trim();
            PRINCAL_SUFFIX = prop.getProperty("hbase.princal_suffix").trim();
            KRB5_CONF = prop.getProperty("hbase.krb5_conf").trim();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
