<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.openshift/config Context.xml中，上下文xml下有：

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

在我的spring mvcservlet-context.xml中是：

<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标记中缺少或错误的属性值。

Spring MVC检查格式良好的html标记。如果您没有填充任何属性，或者这些属性的值错误，它将不会运行，并将给出一条与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"/>
