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

Question

我想知道如何配置我的spring mvc配置xml文件来连接到openshiftpostgresql9.2数据库。我已经对路径.openshift/config目录下的tomcat配置文件进行了更改。 只是想知道如何从openshift tomcat齿轮上部署的spring mvc应用程序连接到openshift postgresql 9.2。 每次我上部署openshift tomcat的战争，我得到错误：

会是什么这样做的原因？每当我用本地数据库连接在本地运行这场战争时，它运行良好，但无法得到当我在openshift tomcat上部署时会发生什么？

在.openshift/config server.xml我下GlobalNamingResources标签具有代码：

<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> 

，并根据上下文XML .openshift/config context.xml是：

<ResourceLink name="jdbc/postgresqldb" global="jdbc/postgresqldb" type="javax.sql.DataSource"/> 

，并在我的Spring MVC servlet-context.xml是：

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

Answer 1

检查您的JSP文件是否丢失或错误属性值在html标签内。

Spring MVC检查格式良好的html标签。如果你错过了填充任何属性或者这些属性有错误的值，它将不会运行，并会给你一条与JasperException相关的错误消息。

我建议使用Spring标记命名空间使用表单时：

<%@ 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在这种情况下是非常有用的，因为如果事情是错了，它会告诉你。
