注解方式

Java代码 // the service class that we want to make transactional @Transactional public class DefaultFfooService implements FooService { Foo getFoo(String fooName); Foo getFoo(String fooName, String barName); void insertFoo(Foo foo); void updateFoo(Foo foo); } |
以下是配置方式, 要么配置service, 要么配置扫描service bean注解也行
