JarCastingSpring Easy Proxy
Library gives an ability to make spring interface proxy beans in easy way (Like spring data repositories do)
Getting started
Maven:
<dependency>
<groupId>org.decembrist.spring</groupId>
<artifactId>spring-easy-proxy</artifactId>
<version>1.0.0</version>
</dependency>
Gradle:
implementation "org.decembrist.spring:spring-easy-proxy:1.0.0"
Example:
@EasyProxy
//1. Define interceptor bean (any org.aopalliance.aop.Advice class)
@Component
public class Interceptor implements MethodInterceptor {
@Override
public Object invoke(MethodInvocation invocation) throws Throwable {
// do some staff
return invocation.proceed();
}
}
//2. Use @EasyProxy annotation to create singleton proxy bean
@EasyProxy({Interceptor.class}) //Interceptor array here
public interface ProxyInterface {
String proxyMethod(String param);
}
@Component
class AnotherClass {
//3. ProxyInterface above will be injected with Interceptor.class handler
@Autowired private ProxyInterface proxy;
}
@EasyProxyInterface
//1. Define interceptor bean (any org.aopalliance.aop.Advice class)
@Component
public class Interceptor implements MethodInterceptor {
@Override
public Object invoke(MethodInvocation invocation) throws Throwable {
// do some staff
return invocation.proceed();
}
}
//2. Use @EasyProxyInterface annotation to create proxy marker
@EasyProxyInterface({Interceptor.class}) //Interceptor array here
public interface ProxyInterfaceMarker {
String proxyMethod(String param);
}
//3. Extend marker interface to create singleton proxy bean
public interface MarkedProxyInterface extends ProxyInterfaceMarker {
String proxyMethod(String param);
}
@Component
class AnotherClass {
//4. MarkedProxyInterface above will be injected with Interceptor.class handler
@Autowired private MarkedProxyInterface proxy;
}
Interceptor injection:
@Component
public class TestInterceptor1 implements MethodInterceptor, ApplicationContextAware {
private ApplicationContext applicationContext;
//The only way to use another beans from interceptor for now
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.applicationContext = applicationContext;
}
Checked:
- Works for kotlin
- @EasyProxyInterface interfaces work as .jar spring boot library component
- Tested with graalvm-ce-java11-21.0.0.2
- Tested with java 8
Properties:
#disable easy proxies
