春季更改应用程序行为：从Java代理到CGLIB代理

[英]Spring changing application behavior : from Java proxies to CGLIB proxies

 原文  2016-05-11 12:38:15  3   1    spring/ jhipster/ cglib

问题描述

The application is on the basis of JHipster. 该应用程序基于JHipster。 This one integrate spring 4.2 (spring boot, spring security, spring mvc/rest, spring data jpa). 这集成了弹簧4.2（弹簧保护套，弹簧安全装置，弹簧MVC /弹簧，弹簧数据JPA）。 I must turn the Jhipster "framework" application from java based proxies to CGLIB proxies. 我必须将Jhipster“框架”应用程序从基于Java的代理转变为CGLIB代理。 It is easy to configure in "DatabaseConfiguration.java" setting : 在“ DatabaseConfiguration.java”设置中进行配置很容易：

@EnableTransactionManagement(proxyTargetClass = true) @EnableTransactionManagement（proxyTargetClass = true）

So now I can use the implementation instead of the interface with @Inject annotation. 因此，现在我可以使用实现而不是带有@Inject批注的接口了。 I need this. 我需要这个。

The problem comes with whole JHipster application not parameterized for this at basis. 问题是整个JHipster应用程序没有为此设置参数。 So when I start application (which start well), I've got NullPointException in spring security framework when I attempt to log in after login form filled (click button), because of this CGLIB configuration. 因此，当我启动应用程序（运行良好）时，由于此CGLIB配置，在尝试填写登录表单（单击按钮）后尝试登录时，我在Spring安全框架中遇到了NullPointException。 (If I rollback this, it works like before). （如果我回滚，它会像以前一样工作）。

What I need to "refactor" in Jhispter so to be able to use CGLIB in whole application. 我需要在Jhispter中“重构”什么才能在整个应用程序中使用CGLIB。

Thanks for your help. 谢谢你的帮助。

  • CGLIB is already working with JHipster/Spring Boot. CGLIB已经在使用JHipster / Spring Boot。 Try generating a service without an implementation, you will see it works. 尝试在没有实现的情况下生成服务，您将看到它起作用。 As you say you want to directly use implementations instead of interfaces, there seems to be a misunderstanding here, as we do it all the time in the project (in fact that's our default usage of Spring Beans). 就像您说的那样，您想直接使用实现而不是接口，这似乎是一种误解，因为我们在项目中一直都这样做（事实上，这是Spring Beans的默认用法）。
  • Indeed you can force having CGLIB proxies with proxyTargetClass = true instead of JDK proxies, for when you have interfaces, but technically this shouldn't make any difference to you. 实际上，对于具有接口的情况，您可以强制使用具有proxyTargetClass = true CGLIB代理而不是JDK代理，但是从技术上讲，这对您没有任何影响。 I would even argue it's better to have JDK proxies for debugging, but that's up to you, of course. 我什至认为最好使用JDK代理进行调试，但这当然取决于您。 My point is that this shouldn't trigger any error, like you have. 我的观点是，这不应像您一样触发任何错误。 I don't understand how this could trigger a NPE in AbstractRememberMeServices anyway, this looks like another issue to me. 我不明白这怎么会触发AbstractRememberMeServices中的NPE，这对我来说似乎是另一个问题。
