我创建了一个产生此输出的Web服务(
)[{"MANAGER_ID":0,"DEPARTMENT_ID":90,"SALARY":24000,"HIRE_DATE":"1987-06-17","FIRST_NAME":"Steven","COMMISSION_PCT":0,"EMAIL":"SKING","EMPLOYEE_ID":100,"JOB_ID":"AD_PRES","PHONE_NUMBER":"515.123.4567","LAST_NAME":"King"}]
下面是我的代码:
package resource;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import javax.naming.NamingException;
import javax.sql.DataSource;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.UriInfo;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
@Path("hr")
public class HumanResources {
@SuppressWarnings("unused")
@Context
private UriInfo context;
/**
* Default constructor.
*/
public HumanResources() {
// TODO Auto-generated constructor stub
}
/**
* Retrieves representation of an instance of HumanResources
* @return an instance of String
* @throws NamingException
* @throws SQLException
*/
@GET
@Produces("application/json")
public String getText() throws JSONException, NamingException, SQLException {
// TODO return proper representation object
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe","hr","hr");
Statement sel = conn.createStatement();
ResultSet rs = sel.executeQuery("select * from employees where rownum <= 5");
JSONObject employees = new JSONObject();
JSONArray emp = new JSONArray();
while (rs.next()) {
JSONObject employee = new JSONObject();
employee.put("EMPLOYEE_ID", rs.getInt("EMPLOYEE_ID"));
employee.put("FIRST_NAME", rs.getString("FIRST_NAME"));
employee.put("LAST_NAME", rs.getString("LAST_NAME"));
employee.put("EMAIL", rs.getString("EMAIL"));
employee.put("PHONE_NUMBER", rs.getString("PHONE_NUMBER"));
employee.put("HIRE_DATE", rs.getDate("HIRE_DATE"));
employee.put("JOB_ID", rs.getString("JOB_ID"));
employee.put("SALARY", rs.getDouble("SALARY"));
employee.put("COMMISSION_PCT", rs.getDouble("COMMISSION_PCT"));
employee.put("MANAGER_ID", rs.getInt("MANAGER_ID"));
employee.put("DEPARTMENT_ID", rs.getInt("DEPARTMENT_ID"));
emp.put(employee);
}
employees.put("EMPLOYEES", emp);
sel.close();
return emp.toString();
}
/**
* PUT method for updating or creating an instance of HumanResources
* @param content representation for the resource
* @return an HTTP response with content of the updated or created resource.
*/
@PUT
@Consumes("text/plain")
public void putText(String content) {
}
}
如果我想在访问数据之前添加身份验证方案,我可以通过哪些方式保护这一点?在我的其他系统中,我在数据库级别(oracle)创建了一个接受用户名和密码的函数,如果有效则返回true,否则返回false。我可以使用这个吗?还是我需要以另一种方式做到这一点?
感谢任何帮助。
感谢。

创建一个新的Web服务方法来处理用户身份验证,给定用户和密码返回一个唯一的会话令牌,必须将其传递给任何后续的Web服务调用,然后您可以检查收到的令牌的有效性。
一个例子:
Authentication(String userName, String userPassword)
方法。SomeOtherMethod(String articleCode, Int articleQuantity, Single articlePrice, String autheticationToken)
方法。authenticationToken
且未过期。
