mybatis为什么用的是mapper接口
接口》代理类》beandefinition》注册器》spring容器
把接口的代理类生成bean定义放到spring容器中怎么弄？如下图：
public class MyfactoryBean implements FactoryBean {
private Class clazz;
public MyfactoryBean(Class clazz){
this.clazz = clazz;
}
@Override
public Object getObject() throws Exception {
Class[] clazzes = new Class[]{this.clazz};
//proxy.newProxyInstance生成代理类
Object proxy = Proxy.newProxyInstance(this.getClass().getClassLoader(),clazzes,new MyInvocation());
return proxy;
}
@Override
public Class<?> getObjectType() {
return this.clazz;
}
@Override
public boolean isSingleton() {
return false;
}
}
public class MyInvocation implements InvocationHandler {
public MyInvocation(){
}
// invocationHandler 的invoke方法作用是动态代理增强
@Override
public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
System.out.println("This is a proxy of ImportTestDao");
return null;
}
}
