用PUnit测试上groovy Sql和spring SimpleJdbcTemplate的性能
日期：2014-05-16 浏览次数：20507 次
一共两个UnitTest，一个PUnit的Runner，代码如下
?
package test;
import java.math.BigDecimal;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import org.springframework.jdbc.core.simple.SimpleJdbcTemplate;
//import org.springframework.jdbc.datasource.DriverManagerDataSource;
import com.mchange.v2.c3p0.DriverManagerDataSource;
import junit.framework.TestCase;
public class InsertQueryJava extends TestCase {
public void testAll() {
DriverManagerDataSource ds = new DriverManagerDataSource();
// ds.setUsername("xx");
// ds.setPassword("xx");
// ds.setDriverClassName("oracle.jdbc.driver.OracleDriver");
// ds.setUrl("xx");
ds.setUser("xx");
ds.setPassword("xx");
ds.setJdbcUrl("xx");
ds.setDriverClass("oracle.jdbc.driver.OracleDriver");
SimpleJdbcTemplate tpl = new SimpleJdbcTemplate(ds);
String sql1 = "insert into xxxx(a, b) values ('test', 100)";
String sql2 = "select a, b from xxxx";
tpl.update(sql1);
int max = 0;
List ll = tpl.queryForList(sql2);
Iterator it = ll.iterator();
while(it.hasNext()){
Map item = (Map) it.next();
BigDecimal x = (BigDecimal) item.get("B");
if(x.intValue() > max)
max = x.intValue();
}
System.out.println(max);
}
}

package test
import com.mchange.v2.c3p0.DriverManagerDataSource;
import groovy.sql.Sql
class InsertQuery extends GroovyTestCase{
void testAll(){
def p = [
url:'xx',
u:'xx',
p:'xx',
driver:'oracle.jdbc.driver.OracleDriver'
]
// def db = Sql.newInstance(p.url, p.u, p.p, p.driver)
def ds = new DriverManagerDataSource()
ds.setUser(p.u)
ds.setPassword(p.p)
ds.setJdbcUrl(p.url)
ds.setDriverClass(p.driver)
def db = new Sql(ds)
String sql = "insert into xxxx(a, b) values ('test', 100)"
String sql2 = "select a, b from xxxx"
db.execute(sql)
def ll = db.rows(sql2)
int max = 0
for(one in ll){
if(one.b > max)
max = one.b
}
println max
// def item = ll.max{it.b}
// println item.b
}
}
?
?
package test;
import org.punit.runner.ConcurrentRunner;
public class Runner {
public static void main(String[] args) {
int threadNum = 20;
new ConcurrentRunner(threadNum).run(InsertQueryJava.class);
new ConcurrentRunner(threadNum).run(InsertQuery.class);
}
}
?
windows下jdk1.6.20 groovy1.8.0
通过运行结果发现了几点表面现象：
?
groovy的Sql，直接newInstance比new Sql(datasource)的性能要好
c3p0的DriverManagerDataSource要比spring jdbc的DriverManagerDataSource的性能要好
都编译成class文件后groovy的性能和java的性能几乎一样
?
下面是Runner结果

后面为了使得数据源连接池有个池的效果，我用了一个全局的DataSource，结果更吃惊。。groovy竟然效率更高
