2、Foo getFoo(String fooName); Foo getFoo(String fooName, String barName); void insertFoo(Foo foo); void updateFoo(Foo foo);/上述接口的一个实现package x.y.service;public class DefaultFooService implements FooService public Foo getFoo(String fooName) throw new UnsupportedOperationException(); public Foo getFoo(S

3、tring fooName, String barName) throw new UnsupportedOperationException(); public void insertFoo(Foo foo) throw new UnsupportedOperationException(); public void updateFoo(Foo foo) throw new UnsupportedOperationException(); classpath:jdbc-config.properties 更进一步：参照Spring2.0参考手册-9.5.5. 有关的设置1.2使用 Transa
