java Spring 2.5.6 SimpleJdbcDaoSupport Transaction 事务验证示例
1.java代码:
//Foo.java
package x.y.service;
public class Foo {
private int id;
private String name;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
//FooService.java
package x.y.service;
//the service interface that we want to make transactional
public interface FooService {
Foo getFoo(String fooName);
Foo getFoo(String fooName, String barName);
void insertFoo(Foo foo);
void updateFoo(Foo foo);
}
//FooServiceImpl.java
package x.y.service;
import org.springframework.jdbc.core.simple.SimpleJdbcDaoSupport;
import org.springframework.transaction.annotation.Transactional;
public class FooServiceImpl extends SimpleJdbcDaoSupport implements FooService {
@Override
public Foo getFoo(String fooName) {
String sql = "insert into Foo values(5,'5555555555555555')";
int cnt2=this.getSimpleJdbcTemplate().update(sql);
System.out.println("affected2:"+cnt2);
return null;
}
@Override
public Foo getFoo(String fooName, String barName) {
// TODO Auto-generated method stub
return null;
}
@Override
@Transactional
public void insertFoo(Foo foo) {
String sql = "insert into Foo values("+foo.getId()+",'"+foo.getName()+"')";
int cnt=this.getSimpleJdbcTemplate().update(sql);
int cnt2=this.getSimpleJdbcTemplate().update(sql);
System.out.println("affected:"+cnt);
System.out.println("affected2:"+cnt2);
}
@Override
public void updateFoo(Foo foo) {
// TODO Auto-generated method stub
}
}
//Test.java
package x.y.service;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Test {
/**
* @param args
*/
public static void main(String[] args) {
ApplicationContext ctx = new ClassPathXmlApplicationContext("applicatinContext.xml", Test.class);
FooService fooService = (FooService) ctx.getBean("fooService");
// fooService.getFoo("");
Foo f1=new Foo();
f1.setId(13);
f1.setName("吴xx2222222222");
fooService.insertFoo(f1);
System.out.println("done");
}
}
2.Spring配置 applicationContext.xml

3.sql
create table Foo ( id bigint primary key, name nvarchar(50) )
运行程序,当注释spring配置的事务时,可以插入一条记录,而配置好spring事务,不能插入记录。
