java - 如何使用java将阿拉伯语单词插入mysql数据库

Question

我有一个 java 应用程序，想将阿拉伯语单词插入 mysql 数据库，我的代码如下所示

Connection con = null;
    String url = "jdbc:mysql://localhost/";
    String db = "students";
    String driver = "com.mysql.jdbc.Driver";
    try {
        Class.forName(driver);
        con = DriverManager.getConnection(url+db,"root","");
        Statement st = con.createStatement();
        String name = new String(txtName.getText().getBytes(), "UTF-8");
        int val = st.executeUpdate("insert into student(name, roll) VALUES('"+name+"','"+txtRoll.getText()+"')");
    } catch (Exception ex) {
        ex.printStackTrace();
    }

但它只插入'??????'。我现在可以做什么？

Answer 1

在 db 变量声明之后添加这个变量:

String unicode= "?useUnicode=yes&characterEncoding=UTF-8";

然后修改你的行:

con = DriverManager.getConnection(url+db,"root","");

到

con = DriverManager.getConnection(url+db+unicode,"root","");
