Question

我想简单地从sql server获取数据并在我的java程序中使用它，因为我使用过：sql server 2017，jdk10，mssql-jdbc-6.2.2.jre8.jar。顺便说一句，我是dindn＆＃39;记得我的sql数据库密码（我的意思是我已经忘记了sql server autentification密码）这就是为什么我使用了integratedSecurity = true并在system32中添加了sqljdbc_auth.dll（我想这对我来说很好）但是出于某种原因，我只是盯着看sql server servicies并在防火墙中为servure连接添加新规则我无法从服务器获取数据，我这样做错误：

java lang classnotfoundexception javax xml bind datatypeconverter

这是我的代码，你知道我该如何解决这个问题？

public void dbConnect(String db_connect_string)
       {
          try {
             Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
             Connection conn = DriverManager.getConnection(db_connect_string);
             System.out.println("connected");
             Statement statement = conn.createStatement();
             String queryString = "select * from tab1";
             ResultSet rs = statement.executeQuery(queryString);
             while (rs.next()) {
                System.out.println(rs.getString(1));
             }
          } catch (Exception e) {
             e.printStackTrace();
          }
       }

    public static void main(String[] args) {
        DBConnection connServer = new DBConnection();

          connServer.dbConnect("jdbc:sqlserver://localhost:51696;databaseName=test;integratedSecurity=true");

    }

java.xml.bind module and has been deprecated and removed from classpath in java 9

Since javax.xml.bind is sub package of Module java.xml.bind you are getting ClassNotFoundException

solution:-

java.xml is deprecated but not removed from Java 9 you have to run by adding below statement

--add-modules java.xml.bind

if you are using maven or gradle just add the below dependencies



    Gradle:-
compile 'javax.xml.bind:jaxb-api:2.3.0'

Maven:-
<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>

无法通过jdbc
