# 项目分享



分享一个项目：[SkyEye](https://github.com/JThink/SkyEye),对java、scala等运行于jvm的程序进行实时日志采集、索引和可视化，对系统进行进程级别的监控，对系统内部的操作进行策略性的报警、对分布式的rpc调用进行trace跟踪以便于进行性能分析。欢迎对分布式跟踪感兴趣的交流~~，交流群：624054633



# 项目介绍



自定义的spring-boot的hbase starter，为hbase的query和更新等操作提供简易的api并集成spring-boot的auto configuration

# 打包

修改相关的maven私服地址

```shell

gradle clean install uploadArchives

```

# 使用方式

## 依赖

```shell

compile "com.spring4all:spring-boot-starter-hbase:1.0.0.RELEASE"

```

## 集成

在spring-boot项目的application.properties文件中加入spring.data.hbase.quorum,spring.data.hbase.rootDir,spring.data.hbase.nodeParent配置项，并赋予正确的值

## 使用

### query

1. 将上述配置项赋予正确的值

2. dto定义

```java

public class PeopleDto {



    private String name;



    private int age;



    public String getName() {

        return name;

    }



    public PeopleDto setName(String name) {

        this.name = name;

        return this;

    }



    public int getAge() {

        return age;

    }



    public PeopleDto setAge(int age) {

        this.age = age;

        return this;

    }

}

```

3. RowMapper定义

```java

import com.jthink.skyeye.data.hbase.api.RowMapper;

import org.apache.hadoop.hbase.client.Result;

import org.apache.hadoop.hbase.util.Bytes;



public class PeopleRowMapper implements RowMapper {



    private static byte[] COLUMNFAMILY = "f".getBytes();

    private static byte[] NAME = "name".getBytes();

    private static byte[] AGE = "age".getBytes();



    @Override

    public PeopleDto mapRow(Result result, int rowNum) throws Exception {

        PeopleDto dto = new PeopleDto();

        // TODO: 设置相关的属性值

        String name = Bytes.toString(result.getValue(COLUMNFAMILY, NAME));

        int age = Bytes.toInt(result.getValue(COLUMNFAMILY, AGE));



        return dto.setName(name).setAge(age);

    }

}

```

4. query操作

```java

import com.jthink.skyeye.data.hbase.api.HbaseTemplate;

import org.apache.hadoop.hbase.client.Scan;

import org.apache.hadoop.hbase.util.Bytes;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;



import java.util.List;



public class QueryService {



    @Autowired

    private HbaseTemplate hbaseTemplate;



    public List query(String startRow, String stopRow) {

        Scan scan = new Scan(Bytes.toBytes(startRow), Bytes.toBytes(stopRow));

        scan.setCaching(5000);

        List dtos = this.hbaseTemplate.find("people_table", scan, new PeopleRowMapper());

        return dtos;

    }



    public PeopleDto query(String row) {

        PeopleDto dto = this.hbaseTemplate.get("people_table", row, new PeopleRowMapper());

        return dto;

    }

}

```

### update等

1. 将上述配置项赋予正确的值

2. update、delete、put操作

```java

import com.jthink.skyeye.data.hbase.api.HbaseTemplate;

import org.apache.hadoop.hbase.client.Delete;

import org.apache.hadoop.hbase.client.Mutation;

import org.apache.hadoop.hbase.client.Scan;

import org.apache.hadoop.hbase.util.Bytes;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;



import java.util.ArrayList;

import java.util.List;



@Service

public class QueryService {



    @Autowired

    private HbaseTemplate hbaseTemplate;



    public List query(String startRow, String stopRow) {

        Scan scan = new Scan(Bytes.toBytes(startRow), Bytes.toBytes(stopRow));

        scan.setCaching(5000);

        List dtos = this.hbaseTemplate.find("people_table", scan, new PeopleRowMapper());

        return dtos;

    }



    public PeopleDto query(String row) {

        PeopleDto dto = this.hbaseTemplate.get("people_table", row, new PeopleRowMapper());

        return dto;

    }



    public void saveOrUpdates() {

        List puts = new ArrayList<>();

        // 设值

        this.hbaseTemplate.saveOrUpdates("people_table", puts);

    }



    public void saveOrUpdate() {

        Mutation delete = new Delete(Bytes.toBytes(""));

        this.hbaseTemplate.saveOrUpdate("people_table", delete);

    }

    

    public void saveOrUpdate() {

        List saveOrUpdates = new ArrayList<>();

        Put put = new Put(Bytes.toBytes("135xxxxxx"));

        put.addColumn(Bytes.toBytes("people"), Bytes.toBytes("name"), Bytes.toBytes("JThink"));

        saveOrUpdates.add(put);



        Delete delete = new Delete(Bytes.toBytes("136xxxxxx"));

        saveOrUpdates.add(delete);



        // 继续add



        this.hbaseTemplate.saveOrUpdates("people_table", saveOrUpdates);

    }

}

```



### 其他

不可以满足需求的可以使用hbaseTemplate暴露出来的getConnection()方法
