Question

WEB-INF / spring-servlet.xml的相关定义如下。

    <bean id="propertyConfigurer"
              class="org.jasypt.spring31.properties.EncryptablePropertyPlaceholderConfigurer">
              <constructor-arg ref="standardEncryptor" />
              <property name="locations">
                    <list>
                            <value>classpath:#{systemProperties.env} jdbc_server.properties</value>
                            <value>classpath:#{systemProperties.env} DBIB.properties</value>
                            <value>classpath:#{systemProperties.env}smtp.properties</value>
                            <value>classpath:#{systemProperties.env}templatedatabase.properties
                            </value>
                            <value>classpath:InstanceOrderWFEmail.properties</value>
                    </list>
            </property>
            <property name="ignoreUnresolvablePlaceholders" value="true" />
    </bean>

“ systemProperties”似乎不是系统属性的有效引用名称。从tomcat加载应用程序时出现以下错误。

    EL1008E: Property or field 'env' cannot be found on object of type 'java.util.Properties' - maybe not public?

Answer 1

“：＃{systemProperties.env}”的语法正确，它引用了JVM属性。我只需要添加-Denv =即可使其正常工作。

无法从spring-servlet.xml创建propertyConfigurer的bean
