eclipse使用（一）

　　使用eclipse时，编写对象的返回值非常麻烦，而使用返回值快捷键可以简化这一过程。

第一种 Alt+shift+L
- 将光标放在有返回值的代码句的分号后面；
```
Resources.getResourceAsStream("mybatis.xml");

new SqlSessionFactoryBuilder().build(resourceAsStream);

factory.openSession();
```
- 按住Alt+Shift+L键，会弹出对话框，输入变量的名字，点击OK即可；

InputStream resourceAsStream = Resources.getResourceAsStream("mybatis.xml");

SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(resourceAsStream);

SqlSession session = factory.openSession()；

第二种 Ctrl+1

将光标放置在有返回值代码句那一行上（分号前后都行）；

Resources.getResourceAsStream("mybatis.xml");

new SqlSessionFactoryBuilder().build(resourceAsStream);

factory.openSession();

选择Assign statement to new local variable ：生成局部变量；

InputStream resourceAsStream = Resources.getResourceAsStream("mybatis.xml");

SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(resourceAsStream);

SqlSession session = factory.openSession()；

选择Assign statement to new field ：生成全局变量；

import java.io.IOException;

import java.io.InputStream;

import java.util.List;

import org.apache.ibatis.io.Resources;

import org.apache.ibatis.session.SqlSession;

import org.apache.ibatis.session.SqlSessionFactory;

import org.apache.ibatis.session.SqlSessionFactoryBuilder;

import com.bjm.pojo.People;

public class Test {

	private static SqlSessionFactory factory;

	private static InputStream resourceAsStream;

	private static SqlSession openSession;

	public static void main(String[] args) throws IOException{

		resourceAsStream = Resources.getResourceAsStream("mybatis.xml");

		factory = new SqlSessionFactoryBuilder().build(resourceAsStream);

		openSession = factory.openSession();

		List<People> selectList = openSession.selectList("com.bjm.mapper.selAll");

		for (People people : selectList) {

			System.out.println(people.toString());

		}openSession.close();

	}

}
