Java 一个Spring应用程序中具有不同上下文的多个servlet

java spring hibernate spring-mvc servlets

Java 一个Spring应用程序中具有不同上下文的多个servlet,java,spring,hibernate,spring-mvc,servlets,Java,Spring,Hibernate,Spring Mvc,Servlets,我有一个Spring应用程序，它必须有两个servlet（dispatcherMain和dispatcherCatalog）通过Hibernate（finance和Financials\u global）处理不同的数据库首先，在web.xml中，我定义：父上下文配置位置（application config.xml） Servlet及其自己的：上下文配置位置（dispatcherMain servlet.xml，dispatcherCatalog servlet.xml）休眠数据源配置

我有一个Spring应用程序，它必须有两个servlet（

dispatcherMain

和

dispatcherCatalog

）通过Hibernate（

finance

和

Financials\u global

）处理不同的数据库

首先，在

web.xml

中，我定义：

父上下文配置位置（

application config.xml

）

Servlet及其自己的：

上下文配置位置（

dispatcherMain servlet.xml

，

dispatcherCatalog servlet.xml

）

休眠数据源配置文件（

databaseConfigMain.xml

，

databaseConfigCatalog.xml

）

Second，在每个servlet的配置文件中，我创建了一个bean

MainConfig

，它为每个servlet读取一个单独的资源包（

mainServlet.properties

和

catalogServlet.properties

）

但事实证明，配置文件从未被读取，因此部署失败。在日志文件中，我有很多

java.lang.RuntimeException:无法读取属性“server.redis”

和

，原因是：klab.backend.utils.MainConfig.get（MainConfig.java:351）

上的java.lang.NullPointerException

我做错了什么

这是我的配置

您是否在启动时启用了spring调试日志？有什么错误吗？@ArunM我有很多

java.lang.RuntimeException:无法读取属性“server.redis”

和

，原因是：klab.backend.utils.MainConfig.get（MainConfig.java:351）上的java.lang.NullPointerException

。您的帐户不应该在吗？可能在SheetalMohanSharma检查此线程<代码>用于父上下文，父上下文只有一个，还是不是？每个servlet是否可以单独使用？抱歉，这是可能的。我检查了类似的线程，你似乎在正确的方向。
