@Service 类的 Spring @Autowired 适用于 Tomcat 但不适用于 Resin答案

【问题标题】：Spring @Autowired of @Service classes works on Tomcat but not Resin@Service 类的 Spring @Autowired 适用于 Tomcat 但不适用于 Resin
【发布时间】：2015-06-04 03:01:18
【问题描述】：

我在 Tomcat 8.0.20 中有一个 100% 有效的解决方案，使用 Spring RESTful 服务和 Spring 核心库打包为 WAR。

当我使用相同的 WAR 并将其放入 Resin 4.0.36（以及 4.0.43）时，我的 @Autowired @Services 无论如何都无法识别。

这让我相信 Tomcat 和 Resin 之间存在环境差异。我是否需要设置一些属性或明确引用某些东西才能使 WAR 在 Resin 上工作？

【问题讨论】：

您使用的是哪个版本的树脂？你能检查一下弹簧罐是否正在加载吗？
我使用的是 Resin 4.0.36，我也尝试在 4.0.43 上部署它。两者都有相同的堆栈跟踪。此外，Spring 库正在启动，这最终导致自动装配失败。
好的，你能包括你的应用程序上下文配置吗？
我已将其添加到原始帖子中。同样，这在 Tomcat 中工作而无需改变一件事。它在 Resin 中不起作用。
得到它，但可能在树脂部署中组件扫描没有到达注解@Service的包，可能的测试是显式创建bean或扫描包“ca.abcc”

标签： spring tomcat spring-data-rest resin

【解决方案1】：

还不知道为什么，但这最终奏效了。我必须识别每个上下文文件：

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:service-context.xml classpath:data-context.xml</param-value>
</context-param>

代替：

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:*-context.xml</param-value>
</context-param>

原始（后一种）解决方案在 Tomcat 中使用 classpath*:* ant 风格的通配符查找非常好，但在 Resin 4.0.42、4.0.43 和 4.0.36 中却不是这样。
