Question

尝试执行serachpage.jsp，它可以在搜索ID的基础上搜索数据库中的数据。基本上我在select语句后出错了。

代码：

<%

try {
    String value = request.getParameter("Issue_ID");
    int Issue_ID=Integer.parseInt(value);
    Class.forName("com.mysql.jdbc.Driver").newInstance();
    Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/report_tracking","root", "root");
    Statement st = conn.createStatement();
    ResultSet rs = st.executeQuery("select * from issue_creating where Issue_ID='"+Issue_ID+"'");
    if(rs.next()) {         
        rs.getString("Problem_Submit");  
        rs.getString("Problem_Submit"); 
        rs.getString("Problem_Descr"); 
    }

%>

错误：

生成的java文件中的行：[108]发生错误：[D：\ mohit \ apache-tomcat-7.0.37 \ work \ Catalina \ localhost_ \ org \ apache \ jsp \ serachisue_jsp.java]
  语法错误，插入“最后”以完成TryStatement

try块缺少

}括号：

try { 
    String value = request.getParameter("Issue_ID"); int  Issue_ID = Integer.parseInt(value);
    Class.forName("com.mysql.jdbc.Driver").newInstance(); 
    Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/report_tracking","root", "root"); 
    Statement st = conn.createStatement(); ResultSet rs = st.executeQuery("select * from issue_creating where Issue_ID='"+Issue_ID+"'");     
    if(rs.next()) {
        rs.getString("Problem_Submit");
        rs.getString("Problem_Submit"); 
        rs.getString("Problem_Descr"); 
    }
} 
catch(Exception e) {
   e.printStackTrace();
}

无法在jsp中执行搜索页面
