Question

我试图使用注入servlet（glassfish）的javax.sql.DataSource

@Resource (name="jdbc/MysqlDS" )
javax.sql.DataSource mysqlDS;

以下语句失败，抛出＆＃34; java.sql.SQLException：访问被拒绝用户＆＃39; userapp＆＃39; @＆＃39; localhost＆＃39; （使用密码：是）＆＃34; ：

con=mysqlDS.getConnection();
PreparedStatement pstmt=con.prepareStatement("select now()");

或

con=mysqlDS.getConnection("userapp","userpassword");
PreparedStatement pstmt=con.prepareStatement("select now()");

但以下成功：

Class.forName("com.mysql.jdbc.Driver");
con = java.sql.DriverManager.getConnection("jdbc:mysql://localhost:3306/user_lindenb", "appuser", "userpassword");
w.println("OK");
con.close(); con=null;

或

con=mysqlDS.getConnection("root","root_password");

或

con=mysqlDS.getConnection("me","mypassword");

或

$ mysql -u appuser --password=userpassword -D user_lindenb -e 'select now()'
+---------------------+
| now()               |
+---------------------+
| 2015-08-05 10:19:07 |
+---------------------+

该补助金被宣布如下：

 grant insert,select,update,delete on user_lindenb.* TO 'appuser'@'localhost' identified by 'userpassword';

并且资源声明如下

asadmin --port  8138 create-jdbc-connection-pool \
            --datasourceclassname com.mysql.jdbc.jdbc2.optional.MysqlDataSource \
            --restype javax.sql.DataSource \
            --property "password=userpassword:user=userapp:serverName=localhost:databaseName=user_lindenb" \
             MysqlDS
asadmin --port 8138 create-jdbc-resource \
            --connectionpoolid MysqlDS \
            "jdbc/MysqlDS"

这个用户的错误＆＃39; userapp＆＃39; ？

谢谢。

Answer 1

我添加

后

grant USAGE on *.* TO 'appuser'@'localhost' identified by 'adminadmin';

一切正常......我不明白为什么。

java.sql.SQLException：用户访问被拒绝＆＃39; userapp＆＃39; @＆＃39; localhost＆＃39; / glassfish
