Java 在OpenShift Tomcat上部署后无法运行Spring MVC Web应用程序？

我想知道如何配置我的spring mvc配置xml文件以连接到openshiftpostgresql9.2数据库。我已经对path.openshift/config目录的tomcat配置文件进行了更改。 我只是想知道如何从部署在openshift tomcat gear上的spring mvc应用程序连接到openshift postgresql 9.2。 每次我在openshift tomcat上部署war时，都会出现错误：

原因是什么？？每当我使用本地DB连接在本地运行这场战争时，它都可以正常运行，但是当我在openshift tomcat上部署时，却无法得到什么结果

在

.openshift/config server.xml

中，我在

GlobalNamingResources

标记下有代码：

<Resource name="jdbc/postgresqldb" auth="Container" type="javax.sql.DataSource"
username="${env.OPENSHIFT_POSTGRESQL_DB_USERNAME}"        password="${env.OPENSHIFT_POSTGRESQL_DB_PASSWORD}"
url="jdbc:postgresql://${env.OPENSHIFT_POSTGRESQL_DB_HOST}:${env.OPENSHIFT_POSTGRESQL_DB_PORT}/${env.OPENSHIFT_APP_NAME}"
driverClassName="org.postgresql.Driver" initialSize="5" maxWait="5000"
maxActive="120" maxIdle="5" validationQuery="select 1"
poolPreparedStatements="true">
</Resource>

在我的spring mvc

servlet上下文中，xml

是：

<beans:bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
    <beans:property name="jndiName" value="java:comp/env/jdbc/postgresqldb"/>
</beans:bean>

检查JSP文件中html标记中是否缺少或错误的属性值

SpringMVC检查格式良好的html标记。如果您遗漏了填充任何属性，或者这些属性的值错误，它将不会运行，并将向您提供与JasperException相关的错误消息

我建议在使用表单时使用spring标记命名空间：

<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>

<form:input type="text" class="form-control" placeholder="Login" maxlength="10" size="10" path="" name="login"/>

---

Eclipse在这种情况下非常有用，因为如果出现问题，它会告诉您。

您能提供一个用于连接的代码示例吗？@corey112358我提供了用于连接的代码。有任何帮助吗？请尝试增强您的答案

<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>

<form:input type="text" class="form-control" placeholder="Login" maxlength="10" size="10" path="" name="login"/>
