java代理—InvocationHandler接口simple实现

定义一个接口

public interface TestService {

    String add(String param1);

    String query(String param1, String param2);

}

实现 InvocationHandler接口

@Data
public class TestProxy implements InvocationHandler {

    private Class interfaceClass;


    @Override
    public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
        String reslut = "invoke " + interfaceClass.getName() + "." + method.getName() + ".args:" + args + " , do anything ..";
        System.out.println(reslut);
        return reslut;
    }

    public Object getProxy(){
        final Class[] interfaces = {interfaceClass};
        return Proxy.newProxyInstance(this.getClass().getClassLoader(), interfaces, this);
    }


    public static void main(String[] args) {
        TestProxy testProxy = new TestProxy();
        testProxy.setInterfaceClass(TestService.class);
        TestService testService = (TestService)testProxy.getProxy();
        testService.add("000000000000000");
        testService.query("000000000000000","11111111111111");
    }
}

输出

invoke com.test.one.TestService.add.args:[Ljava.lang.Object;@7960847b , do anything ..
invoke com.test.one.TestService.query.args:[Ljava.lang.Object;@6a6824be , do anything ..
