spring.aop.proxy-target-class=false
in application.properties
file doesn't help me to force Spring Boot2 to use JDK Proxy.
Aspect
private Logger logger = LoggerFactory.getLogger(this.getClass());
private final String POINT_CUT = "execution(* weatherReport.entity.*.*(..)))";
@Pointcut(POINT_CUT)
private void pointcut() {}
@Before(value="pointcut()")
public void before(JoinPoint pjp) {
logger.info(" Check for user access ");
logger.info(" Allowed execution for {}", pjp);
}
Target Component:
@Component
public class Hello {
public String name = "default";
public String helloStr = "Guys";
public void saySomething() {
System.out.println(this.name+":"+this.helloStr);
}
}
Controller:
@Autowired
private WeatherQueryService weatherservice;
@Autowired
private Hello hello;
@RequestMapping(value="/hello")
public String sayHello() {
System.out.println(weatherservice);
System.out.println(hello.getClass());
hello.saySomething();
System.out.println(hello.getClass());
System.out.println(weatherservice.getClass());
return "hello world";
}
result: class weatherReport.entity.Hello$$EnhancerBySpringCGLIB$$b853a6c3
application.properties
spring.aop.auto=true
spring.aop.proxy-target-class=false
Okay I missed some important theory about JDK Proxy, the target class should implement interface then we can use JDK Proxy. In my code, weatherservice implements an interface, and when I set spring.aop.proxy-target-class to be false, Spring Boot 2 uses JDK Proxy:
class com.sun.proxy.$Proxy62
but when I set spring.aop.proxy-target-class to be true, Spring Boot2 uses default cglib Proxy: class weatherReport.service.impl.WeatherQueryServiceImpl$$EnhancerBySpringCGLIB$$40d58c6
