Cannot aquire lock exception: lock wait timeout exceeded spring sql

Question

Hi I am getting a timeout exception here as the title states and I am not finding any relevant answers as it is the only transaction occurring. Also when I take away the transaction status my test passes just fine. My method for creation:

@Transactional(readOnly = false, propagation = Propagation.REQUIRES_NEW)
public void createAMember(int memberid, String name, String address1, String address2, String town, String contact_number, int bookallowance, double balance, boolean active) {
    String SQL = "insert into member (id,name,address1,address2,town,contact_number,book_allowance, balance, active) values (?,?,?,?,?,?,?, ?, ?)";
    getJdbcTemplate().update(SQL, new Object[] { memberid,name,address1,address2,town,contact_number,bookallowance,balance,active});
    System.out.println("Created Member Name = " + name + " memberid= " + memberid);
    //throw new libException();

}

My actual test:

@Test
@DatabaseSetup(value="classpath:dbEntries.xml", type=DatabaseOperation.CLEAN_INSERT)
public void testCreateMember() throws SQLException{
    MemberDaoJDBCTemplate memberDaoJDBCTemplate=(MemberDaoJDBCTemplate)autoWireContext.getBean("memberDaoJDBCTemplate");
    //int firstCount=memberDaoJDBCTemplate.countAllMembers();
    memberDaoJDBCTemplate.createAMember(id,Name, Address1,Address2,Town,Contact_number,book_allowance,Balance,active);
    System.out.println("kafka");
    //int secondCount=memberDaoJDBCTemplate.countAllMembers();
    //assertNotEquals(firstCount, secondCount); 
}

My datasource bean:

<bean id="dataSource" 
    class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql://localhost:3306/library"/>
    <property name="username" value="root"/></bean>

I am pretty new to this so if I can add anything please just say, I have been wrestling this for awhile so any hints appreciated.Edit1: it is the only test I am running i.e createAMember

Answer 1

It seems that I have either asked a obscure or difficult question or I have asked it in the wrong manner of place. At any rate after much hair pulling I found the answer to this question. My original code that actually attempts to CreateAMember here:

public void createAMember(int memberid, String name, String address1, String address2, String town, String contact_number, int bookallowance, double balance, boolean active) { String SQL = "insert into member (id,name,address1,address2,town,contact_number,book_allowance, balance, active) values (?,?,?,?,?,?,?, ?, ?)"; getJdbcTemplate().update(SQL, new Object[] { memberid,name,address1,address2,town,contact_number,bookallowance,balance,active}); System.out.println("Created Member Name = " + name + " memberid= " + memberid); //throw new libException();

Must be structured more neatly and while identifying types and putting it neatly within a prepared statement. The below re-jigging worked for me. PreparedStatementCreatorFactory psc=new PreparedStatementCreatorFactory(SQL); psc.addParameter(new SqlParameter("id", Types.INTEGER)); psc.addParameter(new SqlParameter("name", Types.VARCHAR)); psc.addParameter(new SqlParameter("address1", Types.VARCHAR)); psc.addParameter(new SqlParameter("address2", Types.VARCHAR)); psc.addParameter(new SqlParameter("contact_number", Types.VARCHAR)); psc.addParameter(new SqlParameter("book_allowance", Types.INTEGER)); psc.addParameter(new SqlParameter("balance", Types.DOUBLE)); psc.addParameter(new SqlParameter("active", Types.BOOLEAN)); Object[] params=new Object[]{memberid,name, address1, address2, town, contact_number, bookallowance, balance,active}; KeyHolder holder = new GeneratedKeyHolder(); getJdbcTemplate().update(psc.newPreparedStatementCreator(params), holder); System.out.println("holder:"+holder.getKey().toString()); System.out.println("Created Record Name = " + name + " ID = " + memberid);

My original method was fine for plain JDBC interaction and this is where the confusion arose. Transactions need the structure as shown above. I hope this post may assist an ignorant so and so like myself at some point.
