这个问题怎么解决啊？maxidle is deprecate总是连接不到数据库

com.alibaba.druid.pool.DruidAbstractDataSource]maxIdle is deprecated
[com.alibaba.druid.pool.DruidDataSource]dataSource-1 inited
[org.hibernate.annotations.common.Version]HCANN000001: Hibernate Commons Annotations 4.0.1.Final
[org.hibernate.Version]HHH000412: Hibernate Core 4.1.7.Final
[org.hibernate.cfg.Environment]HHH000206: hibernate.properties not found
[org.hibernate.cfg.Environment]HHH000021: Bytecode provider name : javassist

参考技术A 你查看 at net.sourceforge.jtds.jdbc.SQLDiagnostic.addDiagnostic(SQLDiagnostic.java:368)
at net.sourceforge.jtds.jdbc.TdsCore.tdsErrorToken(TdsCore.java:2820)
at net.sourceforge.jtds.jdbc.TdsCore.nextToken(TdsCore.java:2258)
at net.sourceforge.jtds.jdbc.TdsCore.login(TdsCore.java:603)
at net.sourceforge.jtds.jdbc.ConnectionJDBC2.<init>(ConnectionJDBC2.java:357)
at net.sourceforge.jtds.jdbc.ConnectionJDBC3.<init>(ConnectionJDBC3.java:50)这几个方法中哪里有问题，这么看结果没有对应的代码是看不出来的 参考技术B 用你配置文件里的用户和密码能单独登陆数据库么？ 参考技术C 有没有考虑权限问题呢？
