问题解决了，在action中定义成List<String>
就可以

<?xml version="1.0" encoding="UTF-8"?>

  <param-name>log4jConfigLocation</param-name>

今天MyEclipse中可以连到数据库上，并且可以显示各个表，可是写个Junit test 抛出异常
Javava.sql.SQLException: Io 异常: The Network Adapter could not establish the connection
JUnit控制台输出是这样的

Could not connect to:  : 11716            
java.net.SocketException: Unrecognized Windows Sockets error: 10106: create
    at java.net.Socket.createImpl(Unknown Source)
    at java.net.Socket.<init>(Unknown Source)
    at java.net.Socket.<init>(Unknown Source)

    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:377)
    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196)

奇怪的是我用笔记本写个测试连接就没问题；
不知道是Myeclipse出了问题还是系统出了问题，之前装各种服务器把系统搞的有点毛病；
希望这里有高人看到了给指点下这个问题原因在哪里~小弟先谢过
