比较Spring、apache和Property的beanUtils效率的案例

平时使用的bean有许多，我们来比较一下；

1.首先建立FromBean和ToBean两个bean类，

package com.testbeanutils;


/**
 * @author zhangjiamei
 * @createtime 2015年10月28日 
 * @version 0.1
 * @instruction 用于测试的bean类
 */
public class FromBean {
private String name;
    private int age;
    private String address;
    private String idno;
    private double money;
 
    public double getMoney() {
        return money;
    }
 
    public void setMoney(double money) {
        this.money = money;
    }
 
    public String getName() {
        return name;
    }
 
    public void setName(String name) {
        this.name = name;
    }
 
    public int getAge() {
        return age;
    }
 
    public void setAge(int age) {
        this.age = age;
    }
 
    public String getAddress() {
        return address;
    }
 
    public void setAddress(String address) {
        this.address = address;
    }
 
    public String getIdno() {
        return idno;
    }

    public void setIdno(String idno) {
        this.idno = idno;
    }
}

2.定义出接口方法执行的接口，

package com.testbeanutils;


public interface IMethodCallBack {

String getMethodName();


    ToBean callMethod(FromBean frombean)  throws Exception;


}

3.写测试类；

package com.testbeanutils;


public class BenchmarkTest {
private int count;


    public BenchmarkTest(int count) {
        this.count = count;
        System.out.println("性能测试" + this.count + "==================");
    }


    public void benchmark(IMethodCallBack m, FromBean frombean) {
        try {
            long begin = new java.util.Date().getTime();
            ToBean tobean = null;
            System.out.println(m.getMethodName() + "开始进行测试");
            for (int i = 0; i < count; i++) {


                tobean = m.callMethod(frombean);


            }
            long end = new java.util.Date().getTime();
            System.out.println(m.getMethodName() + "耗时" + (end - begin));
            System.out.println(tobean.getAddress());
            System.out.println(tobean.getAge());
            System.out.println(tobean.getIdno());
            System.out.println(tobean.getMoney());
            System.out.println(tobean.getName());
            System.out.println("                                      ");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

4.开始测试.

package com.main;


import org.apache.commons.beanutils.BeanUtils;
import org.apache.commons.beanutils.PropertyUtils;


import com.testbeanutils.BenchmarkTest;
import com.testbeanutils.FromBean;
import com.testbeanutils.IMethodCallBack;
import com.testbeanutils.ToBean;


public class TestMain {
/**
     * @param args
     */
    public static void main(String[] args) {
    FromBean fb = new FromBean();
         fb.setAddress("北京市朝阳区大屯路");
         fb.setAge(20);
         fb.setMoney(30000.111);
         fb.setIdno("110330219879208733");
         fb.setName("测试");
         
         IMethodCallBack beanutilCB = new IMethodCallBack() {

@Override
public String getMethodName() {
return "BeanUtil.copyProperties";
}

@Override
public ToBean callMethod(FromBean frombean) throws Exception {
ToBean toBean = new ToBean();
                BeanUtils.copyProperties(toBean, frombean);
                return toBean;
}
};



IMethodCallBack propertyCB  = new IMethodCallBack() {

@Override
public String getMethodName() {
return "PropertyUtils.copyProperties";
}

@Override
public ToBean callMethod(FromBean frombean) throws Exception {
ToBean toBean = new ToBean();
PropertyUtils.copyProperties(toBean, frombean);
                return toBean;
}
};

IMethodCallBack springCB = new IMethodCallBack() {


            @Override
            public String getMethodName() {
                return "org.springframework.beans.BeanUtils.copyProperties";
            }


            @Override
            public ToBean callMethod(FromBean frombean) throws Exception {
                ToBean toBean = new ToBean();
                org.springframework.beans.BeanUtils.copyProperties(frombean,
                        toBean);
                return toBean;
            }
        };
        
        // 数量较少的时候，测试性能
        BenchmarkTest bt = new BenchmarkTest(10);
        bt.benchmark(beanutilCB, fb);
        bt.benchmark(propertyCB, fb);
        bt.benchmark(springCB, fb);


        // 测试一万次性能测试
        /*BenchmarkTest bt10000 = new BenchmarkTest(10000);
        bt10000.benchmark(beanutilCB, fb);
        bt10000.benchmark(propertyCB, fb);
        bt10000.benchmark(springCB, fb);*/


        // 担心因为顺序问题影响测试结果
        /*BenchmarkTest bt1000R = new BenchmarkTest(10000);
        bt1000R.benchmark(springCB, fb);
        bt1000R.benchmark(propertyCB, fb);
        bt1000R.benchmark(beanutilCB, fb);*/


    }
}
