Spring MVC - nested exception is java.lang.RuntimeException: org.postgresql.util.PSQLException: ERROR: relation "userid" does not exist - postgresql

Question

I am making a simple spring MVC application that takes data from a view and sends it to a PostgreSQL database on my machine. I have been following tutorials and am not completely familiar with the bean configuration style of handling connection settings in the Data Access Objects. The error that returns when I attempt to post to the database is as follows:
HTTP Status 500 - Request processing failed; nested exception is java.lang.RuntimeException: org.postgresql.util.PSQLException: ERROR: relation "userid" does not exist
"userid" is my simple postgre table I'm using for testing.
My spring bean configuration file is this:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="org.postgresql.Driver" />
<property name="url" value="jdbc:postgresql://localhost:5432/postgres" />
<property name="username" value="postgres" />
<property name="password" value="kittens" />
</bean>
This is the DAO handling the connection to the DB:
package com.ARSmvcTest.dao.impl;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import javax.sql.DataSource;
import com.ARSmvcTest.dao.arsDAO;
import com.ARSmvcTest.models.ARS;
public class JDBCarsDAO implements arsDAO {
private DataSource dataSource;
public void setDataSource(DataSource dataSource) {
this.dataSource = dataSource;
}
public void insert(ARS ars){
String sql = "INSERT INTO UserID " +
"(ID_, First_, Last_, Email_, Pwd_) VALUES (?, ?, ?, ?, ?)";
Connection conn = null;
try {
conn = dataSource.getConnection();
PreparedStatement ps = conn.prepareStatement(sql);
ps.setString(1, ars.getID_());
ps.setString(2, ars.getFirst_());
ps.setString(3, ars.getLast_());
ps.setString(5, ars.getPwd_());
ps.setString(4, ars.getEmail_());
ps.executeUpdate();
ps.close();
} catch (SQLException e) {
throw new RuntimeException(e);
} finally {
if (conn != null) {
try {
conn.close();
} catch (SQLException e) {}
}
}
}
// FIND ARS BY ID WILL GO HERE EVENTUALLY
}
The spring bean is passing data to the connection successfully as evidenced by this screenshot below:

Despite the dataSource object receiving connection properties from my above spring bean, I notice that the ConnectionProperties field is still null.
Is this what is causing my exception on the Insert attempt?
Lastly I will include a screenshot of the Exception and stack being displayed in browser at the moment of failure:

Answer 1

this exception is directly triggered from the database(-driver).
It tells you that the table named "userid" is not existing.
Please check:
the table name on database and your insert-statement
if the table is read and writabled for the user you use for your connection; you need to have grated the correct right to be able to see and write to the table
I hope this will help you as this seems to be the typical error for this kind of exception.
