当我刷新到一定次数后报错

Answer 1

数据库连接关了的，我用的数据库连接池
数据库关闭代码是：/**
 * 关闭Connection、ResultSet、Statement
 * 
 * @param con
 * @param rs
 * @param stement
 */
public static void closeConnection(Connection con, ResultSet rs, Statement statement){
try{
if(rs!=null){
rs.close();
rs = null;
}
if(statement!=null){
statement.close();
statement = null;
}
if(con!=null&&con.isClosed()){
con.close();
con = null;
}
}catch (Exception e) {

}
}

Answer 2

是否有在finally块里调用你的关闭连接方法？

Answer 3

 Timed out waiting for a free available connection.
1.连接不够用，性能不行，连接数多设置一些，
2.连接没关闭

Answer 4

Timed out waiting for a free available connection.
 1.连接不够用，性能不行，连接数多设置一些，
 2.连接没关闭
