通过Maven更新项目配置后的错误消息

Question

我正在用Maven开发一个项目。过了一会儿，我在IDE (Springsource工具套件)中做了“更新项目配置”。现在我的IDE在抱怨，有一些错误，以前从未出现过。奇怪的是，错误信息似乎是错误的。在下面的代码中，它说我必须删除@重写注释，因为超类必须被覆盖(我实际上是在这样做吗？)

 package org.powertac.humanbroker.services;

        import javax.jms.JMSException;
        import javax.jms.Message;
        import javax.jms.MessageListener;
        import javax.jms.TextMessage;            
        import org.slf4j.Logger;
        import org.slf4j.LoggerFactory;

    public class JMSMessageListenerDecorator  implements MessageListener{

        private static final Logger Log =     LoggerFactory.getLogger(JMSMessageListenerDecorator.class);
        private BaseMessageListener messageListener = null;

        public JMSMessageListenerDecorator(BaseMessageListener l){
            messageListener = l;
        }

        @Override
        public void onMessage(Message message) {

            if (message instanceof TextMessage) {
                try {                               
                    if(Log.isDebugEnabled())
                        Log.debug("Received message "+ message.toString()+" from JMS.");

                    messageListener.onMessage(((TextMessage) message).getText());
                } catch (Exception e){ 
                    Log.error ("The original message leading up to the exception reads ${message.text}.", e);
                }
            } else {
                Log.error ("The JMS Listener knows only how to react to TextMessage objects.");
            }

        }

    }

知道我能做些什么让错误信息消失吗？Thx

PS:在3个不同的类中，我收到了大约5条错误消息，它们都抱怨@重写注释。

Answer 1

在您的pom.xml中，您可能需要这样的内容：

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.3.2</version>
            <configuration>
                <source>1.6</source>
                <target>1.6</target>
            </configuration>
        </plugin>
    </plugins>
</build>

您当前的pom.xml可能会为Java5配置您的项目(可能是默认的)，在这里您使用的是Java6的语言语义。如果将所有内容都配置为适用于Java 6，那么您应该已经全部设置好了。
