数据库连接超市异常我做了一个爬虫软件，需要在不同的服务器上拨号更换IP抓取数据，然后统一收回到一个固定的服务器数据库里面去。发现了一个问题，每次拨号后都会出现一个数据库连接超时的异常，导致部分数据没有传回服务器数据库里，大家有什么办法解决，或者有更好的方案。 org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is org.hibernate.TransactionException: JDBC begin failed: at org.springframework.orm.hibernate3.HibernateTransactionManager.doBegin(HibernateTransactionManager.java:599) at org.springframework.transaction.support.AbstractPlatformTransactionManager.getTransaction(AbstractPlatformTransactionManager.java:374) at org.springframework.transaction.interceptor.TransactionAspectSupport.createTransactionIfNecessary(TransactionAspectSupport.java:263) at org.springframework.transaction.interceptor.TransactionInterceptor.invoke(TransactionInterceptor.java:101) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:171) at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:204) at com.sun.proxy.$Proxy14.executeQuery(Unknown Source) at com.zxj.amazon.tool.AmazonCPCTool.run(AmazonCPCTool.java:327) at java.lang.Thread.run(Thread.java:745) Caused by: org.hibernate.TransactionException: JDBC begin failed: at org.hibernate.transaction.JDBCTransaction.begin(JDBCTransaction.java:96) at org.hibernate.impl.SessionImpl.beginTransaction(SessionImpl.java:1353) at org.springframework.orm.hibernate3.HibernateTransactionManager.doBegin(HibernateTransactionManager.java:558) ... 8 more Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: Connection reset by peer: socket write error at com.microsoft.sqlserver.jdbc.SQLServerConnection.terminate(SQLServerConnection.java:1667) at com.microsoft.sqlserver.jdbc.SQLServerConnection.terminate(SQLServerConnection.java:1654) at com.microsoft.sqlserver.jdbc.TDSChannel.write(IOBuffer.java:1805) at com.microsoft.sqlserver.jdbc.TDSWriter.flush(IOBuffer.java:3581) at com.microsoft.sqlserver.jdbc.TDSWriter.writePacket(IOBuffer.java:3482) at com.microsoft.sqlserver.jdbc.TDSWriter.endMessage(IOBuffer.java:3062) at com.microsoft.sqlserver.jdbc.TDSCommand.startResponse(IOBuffer.java:6120) at com.microsoft.sqlserver.jdbc.TDSCommand.startResponse(IOBuffer.java:6106) at com.microsoft.sqlserver.jdbc.SQLServerConnection$1ConnectionCommand.doExecute(SQLServerConnection.java:1756) at com.microsoft.sqlserver.jdbc.TDSCommand.execute(IOBuffer.java:5696) at com.microsoft.sqlserver.jdbc.SQLServerConnection.executeCommand(SQLServerConnection.java:1715) at com.microsoft.sqlserver.jdbc.SQLServerConnection.connectionCommand(SQLServerConnection.java:1761) at com.microsoft.sqlserver.jdbc.SQLServerConnection.setAutoCommit(SQLServerConnection.java:1901) at org.apache.commons.dbcp.DelegatingConnection.setAutoCommit(DelegatingConnection.java:371) at org.apache.commons.dbcp.PoolingDataSource$PoolGuardConnectionWrapper.setAutoCommit(PoolingDataSource.java:328) at org.hibernate.transaction.JDBCTransaction.begin(JDBCTransaction.java:91) ... 10 more

为什么我的正则表达式不能正确截取字符串？ public static List<String> getString(String str,String star, String end){ Pattern pattern = Pattern.compile("(?<="+star+")(\\S+?)(?="+end+")"); Matcher matcher = pattern.matcher(str); List<String> data = new ArrayList<String>(); while(matcher.find()) data.add(matcher.group()); return data; } public static List<String> getString(String str,String pre,String star, String end){ Pattern pattern = Pattern.compile("(?<="+star+")"+pre+"(?="+end+")"); Matcher matcher = pattern.matcher(str); List<String> data = new ArrayList<String>(); while(matcher.find()) data.add(matcher.group()); return data; } public static void main(String[] args) { String str = "<li>111111111zui2jun1111;" + "222222222</li>333<li>4444" + " 555555</li>666" + "777<li>8888" + " 9999" + "000</li>"; System.out.println(getString(str,"([\\s\\S]*)","<li>","</li>")); String str2 = "<li>111</li><li>222</li><li>333</li>"; System.out.println(getString(str2,"<li>","</li>")); } 结果： [111111111zui2jun1111;222222222</li>333<li>4444 555555</li>666777<li>8888 9999000] [111, 222, 333] 为什么第一个不能像第二个一样把每个符合<li>开头</li>结尾的字符串给截取出来呢我如果要达到第二个的效果要怎么写正则表达式呢
