由 喜欢而已 提交于 2021-01-04 05:40:49
问题 I'm using spring applications which sometimes uses @PostConstruct for setup in code and tests It seems that annotation will be excluded from Java 11: Note that both @PostConstruct and @PreDestroy annotations are part of Java EE. And since Java EE has been deprecated in Java 9 and removed in Java 11 we have to add an additional dependency to use these annotations Article suggest replacing all @PostConstruct with afterPropertiesSet method I recommend you to change implementation from

问题 It says in Java's documentation page for PostConstruct that Only one method can be annotated with this annotation But I just tried annotating three methods of a standalone application with PostConstruct. No compile errors, and all three of them are invoked and executed smoothly. So what am I missing? In what kind of class can and cannot exist multiple PostConstruct annotations? 回答1: Yes, it's seem Spring doesn't follow this restriction. I have found code to process this annotation which is

先看下@PostConstruct的注解 * The PostConstruct annotation is used on a method that needs to be executed * after dependency injection is done to perform any initialization. This * method MUST be invoked before the class is put into service. This * annotation MUST be supported on all classes that support dependency * injection. The method annotated with PostConstruct MUST be invoked even * if the class does not request any resources to be injected. Only one * method can be annotated with this annotation. The method on which the * PostConstruct annotation is applied MUST fulfill all of the following *

问题 I use, JSF Spring OCPSoft Rewrite Glassfish 4 / Jetty 9 I've noticed that my beans invoke @PostConstruct 's init() method twice.

Guice call init method after instantinating an object

由 依然范特西╮ 提交于 2020-01-18 13:36:46
问题 Is it possible to tell Guice to call some method (i.e. init()) after instantinating an object of given type? I look for functionality similar to @PostConstruct annotation in EJB 3. 回答1: Actually, it is possible. You need to define a TypeListener to get the functionality going. Something along the lines of the following in your module definition: bindListener(Matchers.subclassesOf(MyInitClass.class), new TypeListener() { @Override public <I> void hear(final TypeLiteral<I> typeLiteral,
